Classloading problems with 4.0.3RC1 and EJB 3.0 Beta1

koganty Jul 8, 2005 9:07 PM

We are developing an EJB 3.0 application and were using JBoss 4.0.2 and EJB 3.0 Preview 5.
And we just migrated to 4.0.3 RC1 and EJB 3.0 Beta1 and we are running into classloading issues.

Our ejb3 archive file contains some client files that reference other client files that are not part of that ejb3 archive.
The same used to work earlier, but now we get ClassNotFoundException during server startup :

I need to know the structure of your deployment.

Do you have an EAR? What archives are within the EAR? What classes are in which archives.

We have an EJB3 file (extension is .ejb3)
Classes in the EJB3 file include various SLSB, Entity beans, MDBs (all using EJB3 annotations only) and some client (applet related) classes.

IN our specific case we have a TestApplet class that extends a DefaultApplet class. The DefaultApplet class that is not part of the .ejb3 file.

This used to work with 4.0.2 and EJB3 Preview 5.

Why is the deployer in the first place trying to load the TestApplet class?
Or is it that deployer loads all the classes for it to analyze the annotations in it.

Thank You,
Raju

Also, the .ejb3 archive just contains classes only, it doesn't contain any other archives.

Ok, this is a bug and I have fixed in CVS.

But, in the meantime, remove TestApplet from your .ejb3 archive.
