I love GraalVM and I'm a proponent but I still think it's overkill for my use-case.
Mar 18, 2022 · Nicolas Fränkel
I work on software projects since a long time. When I started, we always designed complex architectures just in case something changed: we paid upfront costs, continued to pay throughout the development, and most of the time, the change that we planned for never happened. Change is a constant, but among the infinity of changes, I can bet that your design is not fit for the ones that will happen.
Now, my approach is YAGNI. When you need to change, change it.
Mar 17, 2022 · Nicolas Fränkel
YAGNI. New requirements may never come. They may not evolve. etc.
Sep 13, 2021 · Otavio Santana
Good points but you could have gone much further and made it truly fluent by being compile-time valid using types instead of runtime valid using exceptions.
I explained it in this post.
On the down side, you might get a huge number of types depending on your valid object tree.

Beware of what you find on the WWW ;-)
Here's a post on AWS Lambda with GraalVM https://blog.formkiq.com/tutorials/aws-lambda-graalvm/index.html. I didn't try it.
May 07, 2021 · Kai Hendry
There's no "issue" with Spring. Whatever the framework, you can always run your JVM with a dedicated Java agent that records all interactions and generates the config file for you.
I'm not into serverless but I already read articles on how to GraalVM-ify your Java app and use it as an Amazon Lambda function.
May 05, 2021 · Kai Hendry
I'm a Java developer and I hate Go (mainly because of the return Err pattern).
Anyway, I do love your the process you followed: get the sources, re-execute the tests and try to fix the issues. This is exactly what I find lacking in most comparisons I find regardless of the subject - a scientific approach.
I also am quite "specific" on semantics. In this case, I agree that a native binary starts faster than a VM but not that Go starts faster than Java. Did you know you can code in Java (or any JVM language for that matter) and compile the JAR to a native binary? If you're interested, have a look at GraalVM and its native image capabilities.
Again, great process!
Jan 30, 2018 · Paweł Szeliga
I think you left out the most important point between nullable type and Optional.
You can write that in Java:
Optional<Foo> optional = null;
And now everything is broken again.

I just recently used Vaadin CDI integration v3 in a teaching context and had no issue.
(Note that the Spring Boot integration is really good since the beginning)
Jan 17, 2018 · Duncan Brown
When JSF was first released, I tried it. I remember the 7 or 8 phases lifecycle. The possibility of shortcut through the lifecycle. The fact that JSF was advertised as component-based but there was still a page-to-page navigation. End of the story.
Then I found Vaadin: a true component-oriented framework with event-based programming features. IMHO, that's what JSF should have been. Like some of the Java EE specifications, JSF was designed by very smart people who never had to work in a real-world project. As such, it's too complex with not enough benefits.
Jan 09, 2018 · Michael_Gates
Besides, it's not because your app only loads 4 classes that only those 4 are used. For example, String is defined as:
public final class String implements java.io.Serializable, Comparable<String>, CharSequence
Hence, it will load itself and 3 additional classes.
Jan 09, 2018 · Michael_Gates
> "So the problem with the default JRE is that it executes the all predefined .class files whether you want to or not."
I never understood how it works, the JRE changed recently or this is completely wrong. If a class is not required, then it's just not loaded into memory and that's all. The only downside of a monolithic rt.jar is that it takes space - and that's a no-go on embedded device.

> Scientific studies that OOP results in better readability?
I'm afraid you didn't read my post, or at least the conclusion, because that's exactly the question I ask.
That doesn't allow you to call OOP whatever code you happen to write in Java.
Nov 18, 2017 · Michael_Gates
Quite the opposite, actually. It's just that I don't agree with most developers who think whey use OOP just because they code in Java, and they have getters and setters, etc. I'm (unfortunately?) quite used to the layered architecture and the anemic domain model, as I was taught them first.
Nov 17, 2017 · Michael_Gates
Thanks Alexey,
Actually, I know the guy personnally, and though we don't always agree, I think he's quite good at pure OOP design - to the point where he pursues OOP for the sake of it.
Nov 17, 2017 · Michael_Gates
Then, let me refer you this post.
Nov 17, 2017 · Michael_Gates
I completely agree with you!
Yet, one cannot deny that Spring (and Java EE) code generally doesn't co-locate state and behavior. I just wanted to prove it's possible.
Aug 03, 2017 · Grzegorz Ziemoński
Thanks for your comment.
If you compare the number of steps, sure, your solution is better. But if you check the image size, then you have one single image file weighting 304 MB, while I have 2 weighting respectively 28 MB for Git and 116 MB for Maven.
So it all boils down to your objectives: reducing the number of steps, or having lightweight images.

Pretty smart hack, but still a hack :-)

It's not about new, it's about that one little feature that changes a lot. For me, that feature is extension functions. I don't care that it's present in language X or Y, it just allows me to write much cleaner and readable code than static methods in *Utils classes.
Jul 13, 2017 · Michael_Gates
I don't see in this post what problem I pointed out in Scala. I describe a generic problem, and check how Kotlin and Scala handle it.
I love a good debate, so instead of refering to generalities or using fallacies, please point out detailed arguments. Otherwise, I'm afraid your comment(s) has(have) not added value to the community.

Jul 13, 2017 · Michael_Gates
It's always funny to see such "argument" (cf. Ad hominem logical fallacy).
Jul 11, 2017 · Paweł Szeliga
I beg to disagree. The exception-throwing code has been written, and is available. It's not because you don't use it that a developer won't.
It just feels like trying to put a square peg in a round hole: Java is not made for that.
Jul 11, 2017 · Paweł Szeliga
IMHO, overriding a method to throw an exception at least defeats the principle of least surprise, and at worst is a design flaw. You didn't remove exception, you just pushed them udner the rug.
May 24, 2017 · Ana Jones
Code coverage is a useless metric that project managers like because 1) it's a metric 2) they can understand what it means.
Unfortunately, some things definitely have more dimensions that can be put in an Excel Sheet, such as assertless tests, or boundaries testing, etc.
Please kill code coverage so we can focus on the real subject - tests quality.
Apr 20, 2017 · Grzegorz Ziemoński
1. I never wrote that. I just stated, it's not proper OOP
2. As soon as you write a getter, you'll soon have getA().getB().getC() in your codebase. Discipline is as good as the laziest team member.
3. Good we agree
I've seen that as well, with the same problems.
It seems we more or less agree. My point was that encapsulation or future validation are no reason to write accessors.
Apr 20, 2017 · Grzegorz Ziemoński
That's why you have decorators, and all those nice design patterns.
Apr 20, 2017 · Grzegorz Ziemoński
You're already stating an implementation detail... Let's design the system first, then we can talk about encapsulation.
In your example, then the Car should know how to register itself into the cache manager. Again, you don't need to access its state.
Apr 20, 2017 · Grzegorz Ziemoński
I like stupid examples :-)
But in OOP, you should never query about the state of an object. If you need the license plate for car control, then you ask the Car to check its own license plate, you don't access the data.
Car.checkValidLicensePlate()
Apr 20, 2017 · Grzegorz Ziemoński
Could you elaborate on that? Because I don't see any relationship between accessors and interfaces right now...
Apr 20, 2017 · Grzegorz Ziemoński
If you write getters and setters:
1. You are not doing proper OOP
2. You do not understand true encapsulation
3. If you do that for a possible future validation, YAGNI
The only reason for writing accessors is because most (all?) java libraries assume the JavaBean model.
Mar 23, 2017 · Marcus Biel
I heard that a lot. Care to elaborate about a getter being "only" an implementation detail? And no, there will never be any formatting or whatever involved.
Mar 22, 2017 · Marcus Biel
Why would I use it? To highlight the Pavlov reflex most people have to generate a getter. Because in that case, it's not necessary.
Now, I fully agree with your point. Principle of least surprise, etc.
My point was: stop calling encapsulation $$anonymous$$ property and its associated getter.
Mar 22, 2017 · Marcus Biel
Why would you want your fields to be private if they cannot be changed (like String)?
Mar 22, 2017 · Marcus Biel
Ok, your example convinced me. Thanks for the clarification (and your patience ;-))
Mar 21, 2017 · Marcus Biel
For encapsulation, I've written my arguments there: https://blog.frankel.ch/encapsulation-dont-think-means-think-means/, so I won't repeat myself. I'd be happy to talk further about it if you're interested.
As for the final on class, I still don't get it. If you can override methods, those overriden methods still cannot change final parent fields. So, EvilSpaceship is still immutable. Only if it adds additional fields that are not final, then it might mutable.
Mar 21, 2017 · Marcus Biel
Great article, providing advantages of immutability I didn't formerly think about.
Just nitpicking, but if the type of a field is immutable (like String in your spaceship example), it's not necessary to have it private: public is enough. I admit this is rather strange, but it works.
Also, the class can be not final if all its fields are final. This shouldn't be a requirement IMHO.

Generally speaking, Spring Boot applications do not need child contexts.
Nov 27, 2016 · Fatih Dirlikli
Dependency Injection in general - and Spring in particular, allows to mock/fake dependencies and be able to test the class "in insolation". I fail to understand why injecting the logger would be better than creating it in that regard. Plus you need to write as much (if not more) code to inject the logger nonetheless; hence you've got boilerplate code also.
I can understand declaring the logger is a tedious task. In that case, I'd just create the relevant aspect and use AOP to achieve that. Or Lombok as Jonatan proposes. In both cases, that might be a hammer to squat a fly, though
Oct 28, 2016 · Miro Wengner
Or, you know, just use this thing called a build tool and configure plugins to have be done for you
Oct 25, 2016 · Michael_Gates
You can do even better. With Spring new versions, you can remove the @Autowired annotation entirely on the constructor.
Oct 19, 2016 · Michael_Gates
Happy to have been of service ;-)
Oct 19, 2016 · Michael_Gates
That started well enough until "Use Dependency Injection With Autowired Services", I stopped reading after the code snippet featuring field injection.
Long talk short, even Spring engineers advocate against field injection: I let you read the full article, no need to rant against that practice here again.
Oct 05, 2016 · Nikhil Wanpal
It's not about annotations, it's about style: explicit injection vs autowiring. If you're using explicit, there's nearly a 1-1 mapping between Guice and Spring.
Oct 04, 2016 · Nikhil Wanpal
This comparison is only focused on Spring self-annotated classes without taking into account JavaConfiguration. This post - sadly like many others, pretend to compare Spring that was 10 years ago.
Jun 22, 2016 · Jalal Kiswani, PhD
Quite interesting. But you don't solve the initial problem: the junior developer might forget to use your API and catch silently - or do any of the things you don't want.
In that case, you should use AOP: it's clean and there's no place for error. And in that case, you'd customize the handling of the exception in the aspect itself, thus making your API not so useful.
By the way, regarding your design, using static methods make clients of your API completely unit-untestable. You might want to change that.
Mar 24, 2016 · Dave Fecak
Reply or no reply, it doesn't change a thing. Java EE is the realm of application server vendors and customers who need to have someone to blame. But how many companies are running Tomcat? How many do have issues? Most don't really need the whole Java EE stack. Basically, only a few API are needed: Servlet, JMS, JPA (& JDBC), CDI, JAX-RS and perhaps a few I've forgotten. The rest? Useless... or worse. Batch is a pale copy of Spring and shouldn't have been part of EE. This was a shrewd move on the part of the vendors, so they can sell their high-priced ***ware. And now a MVC? Come on! I've always worked in the Java world with different application servers but this Java EE trend is becoming a tragedy.

Mar 09, 2016 · Alan Hohn
Not at all! It's just an evil snake waiting to bite you at the worst possible moment. It works until it doesn't anymore. It makes your app's structure completely unreadable. It also couples your classes and reduce re-use.
Could we please all switch to Java Config? Pretty please?

I agree that the "Architect" title is sometimes used to charge customers more. However, the problem lies as much on the customer side, as on the salesperson side.
What you're referring to is to have a professional pressure group define the do's and dont's of a particular job. I don't know how it is in the US, but in France such groups include the "Ordre des Medecins" for doctors, "Ordre des Avocats" for lawyers, and so on. In general, those are ancient professions that a. earned the privilege of ruling themselves b. spend much time defending all their advantages instead of the well-being of the society in general. In particular, our lawyers lobbied so you cannot get divorce without a lawyer (one for each side, of course). So, I wouldn't go that way...
Besides, there's no "Architect" per se: I'm generally using the Software Architect title because it makes managers more comfortable. In front of developers, I'll probably say I'm a (Senior) Developer. But I seldom tell people I'm an Enterprise Architect though I've successfully passed the TOGAF certification.
I let some wise words conclude my point:

Builders are very good from a "user" point of view. But if you are the API developer, things tend to get complicated.
Builders are to create objects: but then, the build() method that returns the final object should only be called in a stable state. Moreover, method chaining isn't always idempotent, meaning method calls may have to be ordered. Therefore, as your article describes, you need intermediate classes, and may be in numbers. At this point, I can only give your praises: it tries once with only a couple of limited cases, and that was complex.
Scala is much more adapted to those complex cases, with dynamic types (A with B).

IMHO, annotations are markers; they shouldn't provide any behavior intrisiquely: on the contrary, annotations should be hints for code to manage the annotated class in a different way.
In this light, while annotations stay the same, different codes would manage the annotated class differently.

"Help" should be more precise in your article's title: IMHO, the shared library strategy shouldn't be approached only from a memory point-of-view. Shared libraries also let us enforce enterprise (or projects) policies like set version(s) for libraries. It also put the responsibility from the developer to the server admin for providing the right libraries in the right version.
In the last case, I was once confronted with a library that had been modified by a previous developer so that the JAR contained many more classes and was only vaguely related to its name :-/
While I agree moving libraries from each deployed package to the server reduces agility, technologies such as OSGI can help us reduce the consequences while still bringing the aforementioned benefit.

I also prefer XML to annotations because of coupling :-) only not for transactions.
Spring's XML way of dealing with transaction is way too decoupled for junior (or even senior in some cases) developers. Pattern matching is a little bit dangerous for something as critical as transations, don't you think?
But the heart of the matter is the last point you raise: transactional behavoir shouldn't be part of the design contract for you; for me it should.

Hello,
You matrix is interesting; yet, there's a point you fail to mention. By default, all classes on the classpath are available for injection in CDI whereas only those referenced are in Spring.
Since this is a big source of potential problems, I think you should mention it.

Just an additional info: if your webapp uses HTTPS, you'll need ZAP to generate a dummy certificate (Options -> Dynamic SSL Certificates, Generate button) or import the real one before going further otherwise it won't work. Then accept the browser's security warning if there's one.

John,
Concerning the link, you can check the Red Hat knowledge base, provided you have a Red Hat account with paid support associated.
Second, I completely agree with the provided scope. The problem lies in that as of now, Red Hat doesn't guarantee the binary compatibility of an Open Source library versus a signed one. That means my code may compile just fine with the OS one, and then explode during runtime due to such a incompatibility!
Jun 20, 2011 · Sharon Smith
John, I'm sorry if I mislead you into thinking that open source projects must create their own repos. My point is exactly the contrary: use repo1!
As for your question, yes, the binaries from EAP are not the same from the community edition: they are signed and Red Hat cannot guarantee they are compatible with their open source equivalent!

I am amazed to see how far this XML-bashing trend go: should we be so happy to have replaced a single line XML with 1 line of compiled Java annotation? What's the damn point?
XML is not bad when you have the right tool. Just use Spring IDE and be done with it!

Why use static methods at all? If you use Spring, beans are singleton by default. The only pertinent use case is mocking a static method from a third-party library, which is not apparent from your example.
What's the point in designing static methods? They make your code far more complext to test, and you have to use powerful tools in order to still test them. I wish good luck to the poor developer who has to do the maintenance of your projects, once you're gone...

Hi,
You can also consider another option and use @Transactional in conjunction with <tx:annotation-driven />. It will let you choose which method you would want to make transactional and not make them so by default (which is what you did with the * pattern). As of now, it is my prefered method for managing trasactions (at the cost of coupling my code to Spring).

Some technologies are not human-friendly. It should be the goal of these technologies to get support from popular IDEs.
Another good example is Maven POM which can get pretty complex but is easily readable with m2eclipse Eclipse plugin or NetBeans.

Seems PowerMock is also on the trend: it offers additional features and supports Mockito and EasyMock.
It works without agent but requires that you use its API that in turn calls the chosen framework.

Moreover, you could get 100% coverage without true testing at all. Just write the tests and do not use assertions: work done. The same could be done with JavaDocs, and so on.
That's why you cant' rely on metrics alone.

Hi Andy,
Granted they are more. Yet, from my experience, I've only seen Hibernate (mostly) and TopLink (rarely). Sometimes, they are accessed through JPA...
It would be interesting to have statistics about each use but it isn't far fetched to approximate to these two major actors.
Thanks for your interest.

He he, notice that in my previous comment, I didn't say anything about autowiring?
Older people (like me...) remember that autowring can be used with XML. Well, guess what, I think it's a big error too. And the error gets bigger with bigger projects: haven't experienced it yet like Jonathan and Peter but it smells wrong... It happens when you rely too much on magic behind the scene. Add one more class and kaboom goes your DI! Good luck to you if you are adding features on an already developed application.
@LievenI can't agree with you. Java and JEE, though flawed, have come to be one of the most successfull stack on the server-side. Before JPA, I used Hibernate. I still use it when JPA doesn't fit my needs. Yet, I try to always use standards, when they do not impair development time (like JDO and EJB 2 IMHO).
What if the Spring developers decided to remove @Autowired in the next version of Spring? I wouldn't be able to upgrade Spring's version. Experience have taught me that it never happened in the Java/JEE APIs and I try to build my applications to last. My current customer wants its applications to last 10 years at least: so standards never hurts (less the ones that do... see example above)
@Mitchell
This post and my comment triggered an heated argument among my co-workers and me. Good job and thank you... but I still disagree with the content :-P
Apr 06, 2010 · Peterson Mark
Hi Mitchell,
I'm always happy to read your informative Daily Dose posts. That's why it sadens me to vigorously object to your article's conclusion.
Why do you use DI in the first place? If the answer is 'To decouple your code', then why use a proprietary Spring annotation that will bind you to Spring in the long run?
XML configuration may be (is) a bore, but with the right tool, namely Spring IDE, it is the best solution in terms of decoupling.
Using standard (javax.inject.*) is an option, @Autowired is not.

Like I said before, the benefit is instantly to know the test which failed and thus make the diagnostics easier.
If your tests are dependent on a context that is updated throughout the test run, I would advise you to still separate your big test method into many neat little method and make them dependent: TestNG has this feature (don't know about JUnit though). This clearly gets away from pure unit testing.

Hi Thomas,
I don't know about MagicTest but I fail to see why handling more than one exception per method is desirable. Since the subject is unit testing, I think separating the cases make for a better failed build diagnostics, so I would advise you to use JUnit/TestNG approach.

There are two answers: from a development point of view, this shouldn't be my problem and I have only to use the API. Now, from a production pov, it depends on many factors: what is stored, read frequency, write frequency, and so on... This shouldn't be a black or white answer.
For now, my requirements are simple: intranet, not many concurrent users (50 at most), non critical, and since I make the code reviews, I make sure there's not too much stored in session. So, simple Tomcat clustering would be enough. Terracotta free version would let me be server-agnostic. Too bad I have no admin role for my client...

Why? Because I didn't see anywhere what should be the behaviour of an application server which is tasked to fetched the resource referenced by multipart/context. Should it first checked for a webapp which context root is "multipart", then look for a servlet mapping of "context" or search first for a webapp which context root is "multipart/context"? Not specified anywhere I looked, hence not deterministic, thus a potential bug (or exploitation of one).
Ok, I agree that "deeply" is a figure of style...

Agreed, the price is a real argument against it (though I'm not aware of such a high price). We are now used to free IDEs but I have known the time when you had to pay for these and it was about the same price.
Anyway, apart from purely technical criteria, you have to consider ROI. How much time will you need to do your charts in JavaFX? How much with FlexBuilder? How much are you paid? Then you'll see how much FlexBuilder is really worth in your case.

Very good question! No, I haven't yet and won't use it for a while. I'm working at the moment for a company that is stuck on Java 1.5 and Java 1.6 is a prerequisite for Lombok. To be frank, I wouldn't recommend using any project in production before some companies used it before you: in the companies I worked for, the value is in the business code, not in using the latest products.However, I do think this project should be monitored closely since it could bring some productivity gains soon.

Excellent article considering I asked myself the question not so long ago whether it would be better not to use Transfer Object in small / independent applications.
Transfer Objects are inherited from EJB2 design patterns where you could not transfer entities from the back end to the front-end since you were tied to the EJB container. Nowadays, this behaviour is still used without any thoughts about it.
The only reason to keep this behaviour is to hide your business entitis from other applications. To hide BO from the front end if it's the same application is a waste of time IMHO (at development time and at runtime).
Some tenants of TO care to elaborate the need to use them?
For example, pieni, since you closed your JPA context when you went from the data access tier to the business tier, your BO are not tied to the DB anymore and you can do whatever you want with them: if you do not explicitly reattach them, there's not side effect on the DB.

Jacek,
Executing code client-side or server-side is a major architectural decision that you don't have the luxury to make! For most clients I have worked for, these choices were made before I came. It has nothing to do with this article whatsoever.
Besides, you'll get the same problem in developing from scratch for whatever framework you're using (Swing, .Net, what have you) if you don't have the component you want when needed, which is a common occurence. Making reusable components libraries for your organization is a big step in speeding up development.
I must concede though that JSF architecture favors ease of use over ease of development so new components are a bit complex to develop.

If I remember well what I was taught a looong time ago, OOP is about 3 things: encapsulation, inheritance and polymorphism.
What I understand from this article is that the first one is about to get shot. A more OOP-friendly approach would be the under-the-hood creation of defaults getters/setters if none existed, just like the creation of a default constructor is handled by the compiler. With annotations to configure in case one property shouldn't be accessed.
But I'm perhaps too old to consider new approaches...

Hello,
Don't get me wrong, but displaying tabular data in HTML is done since a loooooong time with the DisplayTaglib. There's a short article on my blog if you're interested. They use taglibs but I see it as an advantage.
For more informations, see their site or their live demos which are really bluffing when you see the tiny amount of config needed on the JSP.
Cheers.
