WebLogic test RMI

Question

Hi,
I'm trying to test a call RMI in WebLogic 10.3.6 but an error is generated...
String serviceAddress = "rmi://localhost:7001/BeanRemoteService";
Naming.lookup(serviceAddress);
java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:
     java.io.EOFException
     at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:286)
     at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:184)
     at sun.rmi.server.UnicastRef.newCall(UnicastRef.java:322)
     at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source)
     at java.rmi.Naming.lookup(Naming.java:84)
Caused by: java.io.EOFException
     at java.io.DataInputStream.readByte(DataInputStream.java:250)
     at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:228)
     ... 7 more
javax.naming.ServiceUnavailableException: error during JRMP connection establishment; nested exception is:
     java.io.EOFException
I have a wlfullclient lib in the classpath...
Can anybody help me?

If Naming.lookup() works, then you muist be binding the server using Naming.bind(). To lookup under the JNDI tree, you must bind the using JNDI, too.

This test case uses the example classes in weblogic/examples/rmi/hello:
The rmi.hello classes are deployed on WL and the following code can connect
from a remote node and get a reference to the remote object.
try {
Hello_WLStub obj = ( Hello_WLStub )
Naming.lookup("t3://192.32.239.58:7511/HelloServer");
catch (Throwable t){
t.printStackTrace();
The following code, using WLInitialContext however, throws a
javax.naming.NameNotFoundException
Hashtable env = new Hashtable(5);
env.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFacto
ry");
env.put(Context.PROVIDER_URL,"t3://192.32.239.58:7511");
Context ctx = new InitialContext(env);
Hello_WLStub obj = ( Hello_WLStub )ctx.lookup("HelloServer");
here's the exception
javax.naming.NameNotFoundException: 'HelloServer'; remaining name
'HelloServer'

Note, there hasn't been any security set up for weblogic.rmi or
weblogic.jndi, or the HelloImpl class. That is, 'everyone' has access.
Thanks,
