Problem with HELLO WORLD

[seemanto]

hi

Can anyone tell me how to get a reference of the home object in a client running in a different jvm but same machine ?

i have set the following properties in my client.

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jnp://localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming

And the i did the following. The idea was to get to the root context of the host and do further lookups.

InitialContext ctx = new InitialContext();
Context context;
context = (Context)ctx.lookup("//localhost");

But it is throwing exception in the line where i have done
lookup("//localhost") Can anyone tell me what might be the problem ?

The exception goes on like this:

The name server knows nothing about '//localhost'. If you want root context, use '/'.

Look at the jndiview mbean to see the structure of the naming hierarchy.

Use following -- >
If you have a jndi.propeties file having the peoperties listing
-----------------------------------------------------------------
InitialContext ctx = new InitialContext();
Context context = (Context)ctx.lookup(System.getProperties());

- OR -

If you want to include it via command line or some other way
-------------------------------------------------------------
Context ctx = null;
Properties props = new Properties();
props.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
props.put("java.naming.provider.url","jnp://localhost:1099");
props.put ("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");

ctx = new InitialContext (props);
