Hi,
I'm going to use JBoss/Tomcat for production but want to use Resin for
development because Resin is much easier to test and develop servlets with.
However, I get an error when I call Handle.getEJBObject(). (Looking up, and
working with, Home interfaces works fine.)
This is the code in my test JSP:
Object ref=new
javax.naming.InitialContext().lookup("java:comp/env/HelloEJB");
HelloHome home=(HelloHome)ref; // Should use PortableRemoteObject.narrow(),
but casting also works with JBoss
Hello hello=home.create(); // This works. The session bean is created.
hello.getHandle().getEJBObject(); // This yields an error, see the
stacktrace below
This is the exception stacktrace:
java.rmi.ServerException: Could not get EJBObject; nested exception is:
com.caucho.naming.NamingExceptionWrapper: java.lang.ClassNotFoundException:
com.sun.jndi.url.HelloEJB.HelloEJBURLContextFactory

JBoss is linked to Resin's JNDI context this way: (This is Resin-specific
configuration.)
<jndi-link>
<jndi-name>java:comp/env</jndi-name>
<jndi-factory>org.jnp.interfaces.NamingContextFactory</jndi-factory>
<init-param java.naming.provider.url="localhost:1099"/>
</jndi-link>
I sent a posting to the Resin interest list over a week ago and didn't get
any replies. Perhaps someone on this list help me out. Invoking
Handle.getEJBObject() in a standalone application works fine, BTW.
