NullPointerException with invoker-interceptor-binding

[shadowcreeper]

When I include a jboss.xml file in my ejb.jar's META-INF directory which has invoker-interceptor-bindings, it always throws NullPointerException in Class.forName0(String).

Please help. Using JBoss 5.1.0CR1. If I remove the invoker bindings all deploys fine.

jboss.xml file:

 <enterprise-beans>
 <session>
 <ejb-name>MyStatelessRemoteBean</ejb-name>
 <configuration-name>Standard Stateless SessionBean</configuration-name>
 <invoker-bindings>
 <invoker>
 <invoker-proxy-binding-name>
 stateless-ssl-invoker
 </invoker-proxy-binding-name>
 </invoker>
 </invoker-bindings>
 </session>
 </enterprise-beans>

 <invoker-proxy-bindings>
 <invoker-proxy-binding>
 <name>stateless-ssl-invoker</name>
 <invoker-mbean>jboss:service=invoker,type=jrmp,socketType=SSL</invoker-mbean>
 <proxy-factory>org.jboss.proxy.ejb.ProxyFactory</proxy-factory>
 <proxy-factory-config>
 <client-interceptors>
 <home>
 <interceptor>org.jboss.proxy.ejb.HomeInterceptor</interceptor>
 <interceptor>org.jboss.proxy.SecurityInterceptor</interceptor>
 <interceptor>org.jboss.proxy.TransactionInterceptor</interceptor>
 <interceptor>org.jboss.invocation.InvokerInterceptor</interceptor>
 </home>
 <bean>
 <interceptor>org.jboss.proxy.ejb.StatelessSessionInterceptor</interceptor>
 <interceptor>org.jboss.proxy.SecurityInterceptor</interceptor>
 <interceptor>org.jboss.proxy.TransactionInterceptor</interceptor>
 <interceptor>org.jboss.invocation.InvokerInterceptor</interceptor>
 </bean>
 </client-interceptors>
 </proxy-factory-config>
 </invoker-proxy-binding>
 </invoker-proxy-bindings>

The jboss-service.xml file declares the "jboss:service=invoker,type=jrmp,socketType=SSL" bean and does not give errors.

Here is the stacktrace:

I moved this from the Clustering/JBoss forum as it has nothing to do with clustering.

Why do you use those invoker-interceptor-binding for? And is this a EJB3 or an EJB2.x application?

[shadowcreeper]

I believe this is an attempt to bind the remote bean to an SSL RMI connection so that data cannot easily be sniffed over the wire.

This is an EJB3 application. I have also tried adding the following to my bean, but still getting the NPE in Class.forName0().

@RemoteBinding(invokerName="stateless-ssl-invoker")

As soon as I try to attach the invoker to my bean, I get the exception.

If there are docs that explain how to do this, please let me know where I can find them as all the docs I saw (even the ones that claimed to be for JBoss v5) say to do it this way.

BTW - I'm not against using the UnifiedInvoker with SSL RMI connections, but this is what was in use on our 4.0.5 server (not sure if it was working, but it was in the code and no errors were being logged).

[alrubinger]

Please file a JIRA under JBMETA and assign to me; I'll have a look and either fix the NPE or give a better deployment exception on failed metadata validation.

[shadowcreeper]

Thanks for the help guys.

I created a bug per instructions, but could not assign it to you.

https://jira.jboss.org/jira/browse/JBMETA-195

If this is indeed misconfigured, please explain (or point me to the documentation which does explain) how to do it correctly.

Thanks.
