Remote EJB Clients - NoClassDefFound Exception

[sriramkanala]

I am trying to lookup an EJB from a remote client. I'm getting NoClassDefFound exception when I try to run the client.

The code I'm using is given below:

Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.naming.HttpNamingContextFactory");

p.put(Context.PROVIDER_URL, "http://:8080/invoker/JNDIFactory");

Context ctx = new javax.naming.InitialContext(p);


I'm getting the exception after this line.

Pl. suggest a solution to this.


Should I modify jndi.properties file in jboss server to use HTTP for RMI calls.

1. If I do that, then how will the local clients access the EJBs?

2. Still I wanted to try it out, so I placed the following in jndi.properties file:
java.naming.factory.initial=org.jboss.naming.HttpNamingContextFactory
java.naming.provider.url=http://[external machine address]:[port]/invoker/JNDIFactory

in jndi.properties. But this caused many exceptions when jboss is started.
Is there anything else that I need to do?

Do you include the jbossall-client.jar in your client classpath?

Don't modify the properties in your jboss server. Why do you want to use http lookup for your server???? This is intended for a non rmi lookup (e.g. behind a firewall).
It won't work until the servlet is deployed and the web service is started.
Use these properties with your client:
[pre]
java.naming.factory.initial = org.jboss.naming.HttpNamingContextFactory
java.naming.provider.url = http://:8080/invoker/JNDIFactory
[/pre]
Provide some more information e.g. exception stack trace, version information if this is not working.
