I am having problems obtaining a reference to an EJB within another EJB
bean. This code snippet,
javax.naming.Context jndiContext = getInitialContext();
Object obj = jndiContext.lookup("CabinBean");
CabinHome home = (CabinHome) javax.rmi.PortableRemoteObject.narrow(obj,
CabinHome.class)
works fine when used in a java client program, but when used within another
EJB, I get this exception when the narrow() function executes:
java.lang.ClassCastException: java.lang.NoClassDefFoundError
Can anyone help me with this? The ejb-jar.xml file appears below. Thanks
for any help.
