Deployment of EAR with Remote EJBs doesn't work

Hello Community,

first of all - thank you for your work. Since the glassfish AS development was moved to Eclipse, the progress is on another level. Kudos to you!

Environment Details

• GlassFish Version 7.0.15:
• JDK version 17:
• OS Windows:
• Database Oracle/Postgres:

Problem Description

We're trying to migrate our application from glassfish 5.1.0 to the current version (7.0.15)
Unfortunately the deployment of our EAR fails because several Remote EJBs cannot be found by the ejb-container.
We've tried to track the problem down and found the commit, which has changed the behaviour of the ejb-container in such way, that the deployment fails:
Commit HASH: 6fbf895
Commit Message: Fixes generated EJB remote interfaces loading
Class com.sun.ejb.codegen.ClassGenerator

Just one code line was replaced by this commit in the method:

private static boolean useMethodHandles(final ClassLoader loader, final Class<?> anchorClass,
final String targetPackageName)

old version:
return Objects.equals(targetPackageName, anchorClass.getPackageName());
new version:
return Objects.equals(anchorClass.getPackage(), loader.getDefinedPackage(targetPackageName));

To be sure, that was the only cause, we've reverted this commit, built the ejb-container locally and the application can be deployed without any further problems.

Our Remote EJB Interfaces and the corresponding implementations are parts of different jars within the EAR. The package names of the Remote EJB Interfaces and their implementation can also differ. The partition is done to provide Remote EJB Interface definitions to other remote service consumer applications in the minimal way.

Kind Regards

Hi, @chicko12345.

Could you please provide the stack traces from the server.log? And, if possible, more information on how to reproduce the problem.

Thanks.

Hi, @avpinchuk,

sorry for the very late answer. Other projects + wanted to create an example to provide something reproducible without the copy of productive code :-D.

The problem seems to be related to the signing of packages.
here:
https://github.com/chicko12345/remote-ejb-test/blob/feature/EJB_SIGN_PROBLEM/remote-ejb-interface/pom.xml
and here:
https://github.com/chicko12345/remote-ejb-test/blob/feature/EJB_SIGN_PROBLEM/remote-ejb-problem/pom.xml
the packages are signed with usage of a jks store.

if <jarsigner.skip>false</jarsigner.skip> the resulting ear cannot be deployed to glassfish.
Without signing(<jarsigner.skip>true</jarsigner.skip>) is all good.

The log contains in case of failed deployment:

Hope, it is enough to understand our problem.
