[jBoss-User] perplexing problem

[John McDonald]

I’m trying to bind an object using jndi. It works great on my local machine, but when I move the application to another machine and attempt to bind “over the network” I get an NPE in NamingContext. I have to be missing something. Can some please help me out with this. It’s driving me _crazy_.   This is the Exception, and the Code is below.   I looked at the source for NamingContext and line 251, and 222 are nothing. <exception> java.lang.NullPointerException:         at org.jnp.interfaces.NamingContext.bind(NamingContext.java:251)         at org.jnp.interfaces.NamingContext.bind(NamingContext.java:222)         at javax.naming.InitialContext.bind(InitialContext.java:303)         at com.tradingproduce.TestMemberRegistration.bindObject(TestMemberRegistration.java:84)         at com.tradingproduce.TestMemberRegistration.<init>(TestMemberRegistration.java:23)         at com.tradingproduce.TestMemberRegistration.main(TestMemberRegistration.java:27) </exception>   Server is the class which implements extends UnicastRemoteObject and implements the remote interface(this is rmi specific, do I still have to do this for jndi?) Jboss is running on 63.199.148.48 and naming is started on port 2101. <code> public void bindObject(){      try{        if(System.getSecurityManager() == null){         System.setSecurityManager(new RMISecurityManager());        }        ObjectSignatureFactory osf = new ObjectSignatureFactory();        ObjectSignature signature = osf.getObjectSignature(this);          System.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");        System.setProperty("java.naming.provider.url", "63.199.148.48:2101");        Server server = new Server();          //bind that baby!        new InitialContext().bind("/applet/" + signature.getSignature(), server);        System.out.println("Server bound and running..");      }catch(Exception e){e.printStackTrace();}    } </code>   What am I missing here?   -jdm
