java.lang.NoClassDefFoundError: Failed to link org/jacorb/orb/Reference

[mgacamedica]

We are migrating JBOSS from 4.0.3SP1 to Wildfly 10.1.0. Our java application is deployed in JBOSS and connects to a CORBA server process (developed in c) running on another host. Our JAVA application uses JACORB implementation. After migrating to Wildfly 10, we are getting following exception in server.log:

We have included the jacorb.jar and all its dependencies in module "com.xxx.yyy:main". Any idea how to fix this error?

I'm reasonably certain that you cannot bundle your own ORB in a deployment and expect it to work.  At least, not without considerable effort.  Have you tried using the bundled ORB?  It should be largely (if not completely) compatible.

Hi David,

Can you please share how to use the ORB that is bundled with wildfly? I could not find any such documentation (may be I am searching properly). Also will using Wildfly's ORB require compilation of our JAVA client classes? Please note that there is no CORBA server running in our JBOSS instance.

What all changes would be required if we want to use our own CORBA implementation?

Thanks,

I've not done it myself, but you need to start by configuring the IIOP-OpenJDK subsystem, described here: WildFly 11.0 Model Reference
