java.lang.IllegalAccessError when invoking protected method from another class in the same package path but different jar.

veitg Apr 12, 2012 11:42 AM

I'm encountering the same problem as described here:

https://issues.jboss.org/browse/AS7-3305

Is there any way, to avoid repackaging the jar's classes into one to avoid the IllegalAccessError? Problem seems that JBoss7 has a separate Classloader for each .jar within the ear.

So the EJB.jar has it's own and the foo.jar under /lib as well which leads to the error. Making the methods public is not an option for me.

I tried the proposed solution with jboss-deployment-structure.xml but that didn't work out for me. Maybe someone could shed some light on this by showing a working example. Tried

several combinations, but always ended up in two separate CLs.

I'm using JBoss 7.1.0 final.

Thanks.

Hi,

did you find a solution? Today I faced the same issue and just found your post...

Actually I don't understand why the related JIRA is rejected.

Regards,
Jochen

I ended up putting everything I need into jar's putting them in the lib folder .

Short story:JBoss uses different CLs for lib and ejb jars. I guess they have their reasons. The rest is a restriction per spec.

thanks for the link.

So I'll start changing a lot of methods to 'public'.
