Hi

I have a RCP applcation using MOXy to parse complex XML, the annotated classes are generated by XJC, and the package contains a ObjectFactory and a jaxb.properties pointing to MOXy.

The application works with Java8, but starting the application with Java11, i get this exception:

java.lang.RuntimeException: javax.xml.bind.JAXBException
 - with linked exception:
[Exception [EclipseLink-50000] (Eclipse Persistence Services - 2.7.4.v20190115-ad5b7c6b2a): org.eclipse.persistence.exceptions.JAXBException
Exception Description: The context path mypackage contains no ObjectFactory or jaxb.index, no external metadata was found in properties Map, and sessions.xml was found or was invalid.
Internal Exception: Exception [EclipseLink-7095] (Eclipse Persistence Services - 2.7.4.v20190115-ad5b7c6b2a): org.eclipse.persistence.exceptions.ValidationException
Exception Description: The sessions.xml resource [sessions.xml] was not found on the resource path.  Check that the resource name/path and classloader passed to the SessionManager.getSession are correct.  The sessions.xml should be included in the root of the application's deployed jar, if the sessions.xml is deployed in a sub-directory in the application's jar ensure that the correct resource path using "/" not "\" is used.]


My target platform contains:
org.eclipse.persistence.moxy_2.7.4....jar
javax.activation-1.2.0.jar
jaxb-api-2.3.1.jar
jaxb-osgi-2.3.2.jar

I use Multi-Release: true to be able to handle Java8 vs. Java9+.
In the main MANIFEST.FM i require org.eclipse.persistence.moxy.
In the versions/9/OSGI-INF/MANIFEST.FM I add the import packages: com.sun.xml.bind.v2, javax.xml.bind

To start the application in the Eclipse run configuration dialog, i switch the JRE Java8 vs Java11, and in the plugins tab, i remove (J8) or add (J11) com.sun.xml.bind.jaxb-osgi (jaxb-osgi.jar) to make it startable.

My question:
Is this the right way to go?
What is this exception and how to solve?

regards
Frank

jaxb-osgi-2.3.2.jar requires 'jakarta.xml.bind-api-2.3.2.jar' (formerly 'jaxb-api') and 'jakarta.activation-1.2.1.jar' and so should moxy. Does updating dependencies fix the problem?

Hello Lukas,

thanks a lot for your reply.

I update the target platform with those jars from the eclipselink zip file:
removed: javax.activation-1.2.0.jar
removed: jaxb-api-2.3.1.jar
added: jakarta.activation.jar
added: jakarta.xml.bind-api.jar
keep: jaxb-osgi-2.3.2.jar
keep: org.eclipse.persistence.moxy_2.7.4....jar

The runtime behavior is unchanged:
Java8 OK
Java11 (11.0.2) the exception from above.

Frank
