Migrating from Java8 EE Tomee8 to Java11+ Tomee9

问题

I see that you're dealing with migration issues related to adopting the Jakarta EE platform and replacing Java EE dependencies with Jakarta EE dependencies. It appears that you're encountering class and dependency conflicts during this process.

Migrating from Java EE to Jakarta EE can indeed be complex, especially when dealing with third-party libraries that still rely on Java EE dependencies. To resolve these issues, you may need to follow these steps:

  1. Carefully review your project's dependencies and identify which ones are still using Java EE namespaces.

  2. For dependencies that are not yet Jakarta EE-compatible, you may need to search for newer versions or alternatives that are compatible with Jakarta EE.

  3. In some cases, you might need to use both Jakarta EE and Java EE dependencies side by side in your project. This mixed usage can be tricky, so you'll need to manage these dependencies carefully to avoid conflicts.

  4. Keep an eye on the documentation and updates of the libraries you're using. Sometimes, library maintainers release newer versions that are Jakarta EE compatible.

  5. Debug and address any class loading or classpath issues that arise during runtime, as indicated by the error messages you provided.

  6. It might be helpful to consult with the communities of the libraries you're using or seek advice from forums and discussion groups dedicated to Jakarta EE migration.

Remember that migrating a large and complex project like this can be challenging, and it may require a significant amount of effort and testing. It's essential to have a good understanding of your project's dependencies and the specific requirements of Jakarta EE to successfully complete the migration.

I've run into a brick wall with this.

What I'm trying to do here, is migrate to Adoptium 17 JDK with Tomee9. Tomee9 here is relevant because otherwise I'd just be using javaEE libraries with a newer JDK target and call it a day. However, due to class names mismatching (mainly EJB interceptors), I get ClassNotFound exceptions when trying to deploy my WAR.

My app relies pretty heavily on old JavaEE code. I'm talking Ejb for injects, javax.ws.rs for webclients, javax.servlets, etc. The ejb migration was painless. Just had to swap the namespace and that was it. A few others required a dependency such as jakarta mail.

So one of the first things I did when trying to migrate, replaced the tomEE javaEE (so javaEE-api) with

    <dependency>
        <groupId>org.apache.tomee</groupId>
        <artifactId>jakartaee-api</artifactId>
        <version>10.0-M1</version>
        <scope>compile</scope>
    </dependency>

This immediately caused issues, which makes sense. Red everywhere due to missing deps. I used the IntelliJ refactor tool, which replaces all Javax namespaces with Jakarta.

However, that's when I realized plenty of my libraries were still using Javax namespaces. To name a few, Auth0:

    <dependency>
        <groupId>com.auth0</groupId>
        <artifactId>mvc-auth-commons</artifactId>
        <version>1.9.2</version>
    </dependency>

Is relying on Javax servlets and Javax HTTP requests. Adding:

    <dependency>
        <groupId>jakarta.ws.rs</groupId>
        <artifactId>jakarta.ws.rs-api</artifactId>
        <version>3.1.0</version>
        <type>jar</type>
    </dependency>

had no effect, I think I still need my old:

    <dependency>
        <groupId>javax.ws.rs</groupId>
        <artifactId>javax.ws.rs-api</artifactId>
        <version>2.0</version>
    </dependency>

In any case, I've ended up in a goose chase of dependency hell (this is a pretty massive and old project), and I'm starting to second guess if my approach is the correct one.

Should I be importing the "necessary" Javax dependencies right back, next to the Jakarta ones? Is there a simple way to avoid all this pain? The libraries I'm using don't seem to care about Jakarta, and it's not really an option to go manually upgrade a bunch of them due to the number of regressions it might cause.

The ones on here have been easy to migrate:
https://blogs.oracle.com/javamagazine/post/transition-from-java-ee-to-jakarta-ee
https://foojay.io/today/migrating-from-java-ee-to-jakarta-ee-with-intellij-idea/

Meanwhile, some dependencies that kinda ship their own, or at least don't have a Jakarta version just don't seem to work:

https://github.com/auth0/auth0-java-mvc-common/issues/97

Now I know you guys hate general questions, and I'm bound to get so much negative engagement here, but this is eating me alive. I sadly need general guidance on how to do this. Am I really supposed to (I will probably just give up instead) port these deps, 1 by 1, hope newer versions fix it. And if there isn't, just do something else.

Mixing some Javax (namely servlet, ws rs client) and some Jakarta (mail, faces etc.) seems like a bad idea, but it's the only way I got it to even compile, while during the run time I get errors such as these:

Notice the no class def found error at the end. This is probably due to me still using javax classes.

Soon as I get rid of this one (although I'm not sure if it's just a coincidence), there's a similar error:

新的 Tomee9 不支持旧的 javax。

您必须将所有库更改为 jakarta 或保留在 Tomee8 上。

请看这里：

https://stackoverflow.com/questions/75680662/tomee-upgrade-from-8-0-13-to-9-0-0-spring-application-caused-by-java-lang-noc

这与您的情况相似。

英文:

The new Tomee9 won't support the old javax.

You have to change all libraries to jakarta or stay on Tomee8.

Please look here:

It's similar to yours.
