Hello my project uses EclipseLink as Jpa provider. My objective is to now use Java 17 and EclipseLink 4.0.0 but here I am getting an error class file for org.eclipse.persistence.internal.weaving.PersistenceWeavedRest not found

I tried looking into
1. https://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Advanced_JPA_Development/Performance/Weaving/Static_Weaving and
2. https://github.com/empulse-gmbh/eclipselink-static-weave-plugin

which says this way is for Java 8 and EclipseLink 2.5.1 Moreover it uses a plug in

<groupId>de.empulse.eclipselink</groupId>
<artifactId>staticweave-maven-plugin</artifactId>
<version>1.0.0</version>
which is of 10 years ago and no updates. My project works fine with these versions but I have a requirement to upgrade to newer versions. So how should I proceed. How should I do the static weaving. Please help.

Hello Thanks for the reply. This also uses <groupId>de.empulse.eclipselink</groupId>
<artifactId>staticweave-maven-plugin</artifactId>

is it still usable in Java 17 and EclipseLink 4.0.0 Also has EclipseLink removed org.eclipse.persistence.internal.weaving.PersistenceWeavedRest because this is the error I am getting that this class file is not found. When I try to see in older version, I find this Class but not in the latest version of EclipseLink. Do we have any alternative

Hi Alok,
did you find a solution for your static weaving problem?

The reason why I'm asking is that we recently run into the same issue which a persistence unit where we use static weaving and eclipselink 4.0.3 in a Java 17 modularized environment.

And it looks like that the tagging interfaces

org.eclipse.persistence.internal.weaving.PersistenceWeaved;
org.eclipse.persistence.internal.weaving.PersistenceWeavedChangeTracking;
org.eclipse.persistence.internal.weaving.PersistenceWeavedFetchGroups;

and its corresponding package

org.eclipse.persistence.internal.weaving is not exported by the

org.eclipse.persistence.core module.

Best regards,
Manfred
