RE: [jBoss-User] perplexing problem

[John McDonald]

Marc, Well, here is the problem I’m having. A remote object cannot register itself over the network(per my last email). So I tried sending this object(in a hashmap with some other data) to a servlet. I want the servlet to be responsible for registering the object. The problem is that when I retrieve the remote interface for this object(context.lookup(“someobject”)) and call a method on it, for some reason a local copy of the object is being executed instead of the remote object. I know this is happening because I have two console windows open: one which represents the remote object and one for the servletserver. The method I am executing simply prints some stuff to the console. The servlet server window is written to, not the window for the remote object.   I hope I explained that correctly. Any ideas?     -----Original Message----- From: marc fleury [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 31, 2000 3:24 PM To: jBoss Subject: RE: [jBoss-User] perplexing problem   come again?   marc   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John McDonald Sent: Thursday, August 31, 2000 3:11 PM To: 'jBoss' Subject: RE: [jBoss-User] perplexing problem Is there a way that I can pass a reference of the object to the remote server, register is “locally” on the server and still maintain the reference to the remote object and not a local object representation of the remote object?       -----Original Message----- From: John McDonald [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 31, 2000 2:07 PM To: 'jBoss' Subject: RE: [jBoss-User] perplexing problem   I really appreciate your reply Marc. One note is that on the DreamBean site, the JNP(java naming provider), which I think was written by Rickard, claims that one can bind objects remotely. This is exactly what I need. Rickard..are you out there. The link is: http://www.dreambean.com/jnp.html. It’s at the bottom of the page. I haven’t specifically tried using his naming provider because I assumed that it is was bundled with Jboss.   If anyone has tried binding objects remotely, please let me know of your success. In the mean time, I’ll open a bug report.   Thanks.   -jdm   -----Original Message----- From: marc fleury [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 31, 2000 2:07 PM To: jBoss Subject: RE: [jBoss-User] perplexing problem   that is interesting I guess we never tried to get the naming service on a separate machine, but we should do that as we move to production quality and offer redundant naming services....   interesting, please open a bug with this and we will try to see whether it is real.  Any information you can dig is useful john, thanks   marc   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John McDonald Sent: Thursday, August 31, 2000 1:26 PM To: '[EMAIL PROTECTED]' Subject: [jBoss-User] perplexing problem 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
