Hi everyone,
I am trying to connect to an EJB3.0 remote session bean (deployed in an ear on
JBoss V4.0.5) from a tomcat V5.5 webapp. The tomcat and the JBoss installation
are deployed on different machines.
I get the following ClassCastException in a call to PortableRemoteObject.narrow:
java.lang.ClassCastException
at
com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:229)
Caused by: java.lang.ClassCastException: javax.naming.Reference
at
com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:212)
Here is my client code:
String urlName = "jnp://156.135.155.156:1099";
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
p.put(Context.PROVIDER_URL, urlName);
p.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
InitialContext ic = new InitialContext(p);
Object ref =
ic.lookup("SDOCIBusinessApp/SDOCIBusinessServiceImpl/remote");
SDOCIBusinessService narrowed = (SDOCIBusinessService
)PortableRemoteObject.narrow(ref, SDOCIBusinessService.class);
Here is the list output of jmx-console:

| | +- local (proxy: $Proxy82 implements No ClassLoaders found for:
ch.skyguide.aim.interfaces.businesslogic.exportinvoker.IBriefingExportInvoker
(no security manager: RMI class loader disabled))
I have packaged the EJB plus interfaces in an SDOCIBusinessApp.ear to be
deployed on jboss and also as a jar in the WEB-INF/lib directory in the war
file of my webapp since the webapp needs to reference the interface
SDOCIBusinessService.
I have read all sorts of posted topics which seem to deal with this
ClassCastException but I haven't found the solution to my problem yet.
Can anybody help?
