Problem with IntraVmProxy when using openEJB in a embedded way.

[Marcelo de Oliveira Dias]

Hi folks.

Let me explain my problem:
I'm using OpenEJB embedded with Jetty. I have created a WebApp that have a
Servlet which instantiates the OpenEJB, deploy all of its EJBs (just one in
that case, called Catalogo), and deploy other EJBs from others WebApps that
are running on Jetty (just one in that case, called CatalogoLivraria).

And it has a service to handle the EJB requests:*
    protected void service(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
        ServletInputStream in = request.getInputStream();
        ServletOutputStream out = response.getOutputStream();
        try {
            ejbServer.service(in, out);
        } catch (ServiceException e) {
            throw new ServletException("ServerService error: " +
ejbServer.getClass().getName() + " -- " + e.getMessage(), e);
        }
    }*

The deployment seems that works, I get the Log messages:
*
*For the EJB that belong to my "Embedder openejb webapp"
*INFO - Jndi(name=CatalogoLocal) --> Ejb(deployment-id=Catalogo)
INFO - Jndi(name=CatalogoRemote) --> Ejb(deployment-id=Catalogo)
INFO - Created Ejb(deployment-id=Catalogo, ejb-name=Catalogo,
container=Default Stateless Container)*

For the EJB that belong to another webapp
*INFO - Jndi(name=CatalogoLivrariaLocal) -->
Ejb(deployment-id=CatalogoLivraria)
INFO - Jndi(name=CatalogoLivrariaRemote) -->
Ejb(deployment-id=CatalogoLivraria)
INFO - Created Ejb(deployment-id=CatalogoLivraria,
ejb-name=CatalogoLivraria, container=Default Stateless Container)

*When I run a simple J2SE ejb client that "look up" at "Catalogo" it works
ok!
But when I run it "looking up" at "CatalogoLivraria" a get this exception:

*javax.naming.NamingException: Unknown error in container [Root exception is
java.lang.IllegalArgumentException: interface
org.apache.openejb.core.ivm.IntraVmProxy is not visible from class loader]

*I guess that my problem is related to how my Servlet deploys the EJBs.
And how this proxy is instantiated by "Proxy.newProxyInstance()" in the
class "org.apache.openejb.util.proxy.Jdk13ProxyFactory".
Which is likely a ClassLoader problem.

I'm sure that the *IntraVmProxy *is visible. Taking a look at the peace of
code that throws that exception in "Proxy.newProxyInstance()" we have:

*String interfaceName = interfaces[i].getName();
  367               Class interfaceClass = null;
  368               try {
  369                   interfaceClass = Class.forName(interfaceName,
false, loader);
  370               } catch (ClassNotFoundException e) {
**  371               }
  372               if (interfaceClass != interfaces[i]) {
  373                   throw new IllegalArgumentException(
  374                       interfaces[i] + " is not visible from
class loader");
  375               }*

 So maybe, if it is visible, it is visible by a wrong ClassLoader.

I know that what I'm trying to do isn't easy. So any thing that helps me to
understand why I'm having this problem with "Proxy.newProxyInstance()" will
be very "helpful" :-)

Thank you a lot in advance,
