WebSphere Liberty BASE Remote EJB call failed in JDK 17

Question

Here I'm trying to initiate a remote ejb call between two JavaEE applications which are deployed in two separate VMs, When I initiate remote ejb lookup from the primary JavaEE application following error trace will appear in the secondary server's console log.

Please note that both JavaEE applications are deployed in JDK 17 runtime and the remote ejb lookup will be performed as below,

Context ctx = new InitialContext(jndiProps);
Object remoteObj = ctx.lookup("corbaname:iiop:10.0.0.127:2809/NameService#ejb/global/app_server_2/RMS.jar/OMSCoreServicesBean#com.dfn.oms.newgen.core.tx.service.OMSCoreServicesWrapperRemote");
return (OMSCoreServicesWrapperRemote) PortableRemoteObject.narrow(remoteObj, OMSCoreServicesWrapperRemote.class);

Can someone suggest a way to fix this issue?

Answer 1

This could be a problem with module access in Java 17.

• Is there any more stack trace?
• Are there any other error or warning messages?
• Is there a logs/ffdc folder in your server directory that contains more information?

If we can figure out some missing module access, we can add it locally it for your server.
