Java EJB client "Can't connect to ORB" errors...

Question

I'm writing an application that is a Java EJB client application (no web
stuff at all). Needless to say there are no examples of such an app in
the samples dir, they are all web-based.
My problem is that when I try to run my application (client calls a
stateless session bean on the server and gets a "hello world" string
back) I get a "Could not create the TestService bean:
javax.naming.CommunicationException: Cannot connect to ORB [Root
exception is org.omg.CORBA.COMM_FAILURE:   minor code: 1 completed:
Maybe]" error.
This is a very simple test, and I'm getting quite frustrated in trying
to figure out what's actually wrong.
Here's the client code (the bean on the server has been deployed into a
module called achptestEjb, the bean name is TestService)
TestService service = null;
TestServiceHome home=null;
String host = "localhost";
String port = "12345";
try {
Properties env = new Properties();
Context context=null;
String jndiName="ejb/achptestEjb/TestService";
System.out.println("JNDI name is "+jndiName);
env.put
("java.naming.factory.initial","com.sun.jndi.cosnaming.CNCtxFactory");
env.put("java.naming.provider.url", "iiop://"+host+":"+port);
context = new InitialContext(env);
The error comes when the new InitialContext is set with the properties
in the env object.
Any ideas what I'm doing wrong?
It would be a BIG help if iPlanet included one simple pure EJB client
example. There are some of us out here who feel HTML is too limiting
for complicated applications.

Answer 1

I finally found the answer to my problem.... in the Ant script I had
copied from another example, the "-iiop" was lacking in the ejbc
arguments - almost all of the examples assume you'll be calling EJBs
from within the container, instead of a stand-alone client, so they
don't use that flag.
Putting that "-iiop" flag into the ejbc arguments fixed everything.
Thanks, Shivani, for pointing out what is now obvious but was
mysterious.
