Investigation on the jberet usage on the WildFly

jberet-wildfly.md

project:

• https://github.com/jberet/jberet-wildfly-samples

Currently the examples doesn't support EE9 yet:

So I downgrade my JDK version to build the project:

However the build failed with Null Pointer failure:

This project currently does not build with jdk 11. To see the root cause of failure, I ran the following command:

mvn clean install -X -Dmaven.compiler.forceJavacCompilerUse=true

So from the above error message, the jaxb api is not there. It is part of Java 8 but was pruned in Java 9 or 10. So we just need to add jaxb-api dependency to fix the above problem. There may be other issues after that.

I'll try to bring this project up to date, creating a 1.x branch for javax.batch API, and keeping master branch for jakarta.batch API.

Thanks for checking! @chengfang

@chengfang I extracted one of the example and created this project:

• https://github.com/liweinan/play-jberet-rest-api

I started the server by running:

$ mvn wildfly:run -DskipTests

And then run the test:

Though the test passed however the server throws some error messages:

I'm not sure how to fix it, could you please help to check it? Thanks!

since the error points at line 1 col 0, so it could yasson is expecting some json payload but somehow got empty json object. You may want to check if a json payload is needed in your request.

another possibility is the client side (resteasy, etc) libs may be too old.

Also I've updated https://github.com/jberet/jberet-wildfly-samples project with various lib upgrades and fixes.

@chengfang I'll check the updated examples. thanks for help!

@chengfang After upgrading the jberet-wildfly-samples project locally, I can build the project now. And I went on running the tests restAPI example. I run the start() test and I can reproduce the INVALID TOKEN problem:

Could you please help to check it? Thanks!

sure, I'll take a look. It could be some problem with jberet-rest-api, which has not been updated for a while. I noticed all rest* sub-modules within jberet-wildfly-samples failed with the above error.

@chengfang thanks!
