JWS - EJB JNDI Lookup problem

Question

Hi,
I have a client Java application accessing a session EJB in a remote JBoss J2EE server. I'm using JWS 1.2 to deploy my application but when I do a JNDI lookup to get access the the remote's object home interface I get this error:
"Need to specify class name in environment or system property, or as an applet parameter, or in an application resorce file: java.naming.factory.initial"
All the jar files are signed and the JNPL file contains <all-permissions/>. This is the code that triggers the exception
jndiContext = new InitialContext();
homeRMIReference = jndiContext.lookup(C_SERVICE_NAME);
Any help would be appreciated.
Thanks in advance,
Rafael

Hi,
I've finally found the origin of the problem.
1. JNDI uses a minimum set of properties during initialization phase:
java.naming.factory.initial
java.naming.factory.url.pkgs
java.naming.provider.url
Therefore these properties must be set in the <resource> topic of the JNLP file. The value of these properties is defined in the jndi.properties file that you can find in jbossjmx.ant.jar (within the jboss/client directory)
2. You have to add the JBoss files to your bundle. For doing so I've unjared all the .jar files within the jboss/client directory; afterwards I have jared them in a single file "jboss.jar" and I've signed the file. I've added jboss.jar to the <resource> tag within the JNLP file (Note that I've added all the jboss files just to do quick check but usually you will have to add only those files you need (it doesn't make sense to deploy all JBoss files in each client application)
I hope this helps,
