    interface javax.xml.rpc.Stub is not visible from class loade

      Hi,

      This seems to be a JNDI classloader issue but I do not know where to start.

      I have a portlet
      ->which looks up via JNDI a Module (extending org.jboss.system.ServiceMBeanSupport)
      ->which looks up via JNDI an wsee application client
      ->which in turns call a webservice

      All this happens on the same server (Jboss 4.0.2), same JVM (jdk 1.4.2 - j2ee 1.4)

      All the JNDI lookups work fine however when I try to access the port, the following exception is thrown:

      javax.xml.rpc.ServiceException: java.lang.IllegalArgumentException: interface javax.xml.rpc.Stub is not visible from class loader
      at org.jboss.axis.client.Service.getPort(Service.java:559)
      at org.jboss.axis.client.Service.getPort(Service.java:460)
      at org.jboss.webservice.client.ServiceImpl.getPort(ServiceImpl.java:180)
      at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
      at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
      at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
      at java.lang.reflect.Method.invoke(Method.java:324)
      at org.jboss.webservice.client.ServiceProxy.invoke(ServiceProxy.java:124)
      at $Proxy232.getMyPort(Unknown Source)
      ....

      Interestingly enough, another module located in the same jar an calling the same application-client does not throw this exception. This other module however is not looked up from a portlet (but rather the Jaas Securiy Manager).

      javax.xml.rpc.Stub seems however to be a pretty basic interface that I would assume would be visible from anywhere on the server.

      Do you have any clue where this issue could be coming from?

          To add to above, the problematic lines in org.jboss.axis.client.Service.getPort are

          ClassLoader classLoader = Thread.currentThread().getContextClassLoader();

return (Remote)Proxy.newProxyInstance(
 classLoader,
 new Class[]{proxyInterface, javax.xml.rpc.Stub.class},
 new AxisClientProxy(call, portName)
);


          Why in the case described above does the Context classLoader not "see" javax.xml.rpc.Stub?

          Bruno.
