[jacorb-developer] JacORB hangs in endless connection retry loop

[Franz van Betteraey]

Hi Phil,
 
we use JacORB together with Apache CXF to establish the connection. The address we use there (in the JaxWsProxyFactoryBean) is something like "corbaname::<NameService>:<NameServicePort>#<ServiceName>".
Meanwhile we used the "Ultra Corba Simulator" to connect to the service and the behaviour is as expected (exception after unsuccessful retries). So I assume that the endless loop behaviour is related to Apache CXF although I can not find something helpful in the logs.

Nevertheless when we use the SUN ORB we get an Exception as expected (even when using Apache CXF)

Jun 25, 2015 9:07:12 PM com.sun.corba.se.impl.transport.SocketOrChannelConnectionImpl <init>
WARNUNG: "IOP00410201: (COMM_FAILURE) Connection failure: socketType: IIOP_CLEAR_TEXT; hostname: <server>; port: <port>"
org.omg.CORBA.COMM_FAILURE:   vmcid: SUN  minor code: 201  completed: No
       at com.sun.corba.se.impl.logging.ORBUtilSystemException.connectFailure(ORBUtilSystemException.java:2200)
       at com.sun.corba.se.impl.logging.ORBUtilSystemException.connectFailure(ORBUtilSystemException.java:2221)
       at com.sun.corba.se.impl.transport.SocketOrChannelConnectionImpl.<init>(SocketOrChannelConnectionImpl.java:223)

So probably the failure is on the Apache CXF side. Nevertheless, thanks for your comments.

To solve the current problem we will not use Apache CXF at the moment, but it would be nice to know the cause of the problem.

Kind regards,
  Franz

Hi Franz,

Are you using a corbaname style URL?
How is the server not responding? It looks like it has a listen socket open but it is not accepting the new connection.
What does the Java ORB do?
