Can not find my EJB's from my Servlet

Question

Hi
I am new to EJB and am trying to get a Servlet to call some sessionless EJB beans. I have got it working in JDeveloper but when I deploy it to orion application server I keep getting a javax.naming.NameNotFoundException exception throw from the Servlet when it tries to find the first EJB.
The code in the Servlet is:
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "jewels");
// env.put(Context.PROVIDER_URL, "ormi://localhost:23891/current-workspace-app");
env.put(Context.PROVIDER_URL, "ormi://localhost:23791/dev");
Context ctx = new InitialContext(env);
System.out.println("Getting mapping class ejb");
//mapping
ExponentMappingServiceHome mappingHome = (ExponentMappingServiceHome)ctx.lookup("ExponentMappingServiceHome");
ExponentMappingService mapping = mappingHome.create();
My EJB xml looks like this:
<?xml version = '1.0' encoding = 'windows-1252'?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN" "http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd">

<ejb-class>com.exponent.ejb.service.FalconServiceBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</session>
</enterprise-beans>
</ejb-jar>
I have been trying for a while to get the JNDI naming right but everything I try gets the above error. Any help would be great.
Thanks

You have to lookup for "ExponentMappingService", and not "ExponentMappingServiceHome"
The name you give in the <ejb-name> tag in ejb-jar.xml is the JNDI name of the EJB. This is the name u have to look up.
