InitialContextFactory to connect from java to OID

Question

Hi,
I have a problem to connect from my application java to OID, I was using the following InitialContextFactory in my code in this way:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.ApplicationClientInitialContextFactory");
env.put(Context.PROVIDER_URL, "ormi://192.168.3.112:3061/dn=fedco,dn=com");
but it gives back the following error to me:
Problem looking up : javax.naming.NamingException: META-INF/application-client.xml resource not found (see J2EE spec, application-client chapter for requirements and format of the file).
I have been looking for about the xml files but I have found that they are necessary when one works with EJBs which is not my case, I need to know if I am using the appropriate InitialContextFactory or if another one is the appropriate for this case.
Please, help me.
Thanks.

Hi there,
You are definately using the incorrect InitialContextFactory. The com.evermind.server.ApplicationClientInitialContextFactory is intended for Standalone Java clients that require access to remote EJBs AND have been configured with a client-application.xml file.
Try the following:
//Setup intial context for OID server
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, ldapURL);
env.put(Context.SECURITY_AUTHENTICATION, "none");
env.put(Context.SECURITY_PRINCIPAL, dn);
// Anonymous bind to create the intial context
try
dirCtx = new InitialDirContext(env);
log.debug("New LDAP context created " + dirCtx);
catch (NamingException ne)
log.error("Failed to create InitialContext for LDAP server:", ne);
throw new RuntimeException("LDAP server is not available");
Where ldapURL is "ldap://<host>:<port>" and dn is the OID content you are interested in e.g. "dc=site,dc=company,dc=com".
Hope this helps.
