How to change JNDI service provider for EJB's?

Question

I need EJBean's home interface to be bound to another JNDI provider, not Weblogic.
How can I do it?
The most simple solution is not working: to specify <jndi-name> in weblogic-ejb-jar.xml
for bean as "xxx:bean_name".
By JNDI rules for such names context factory with name com.sun.jndi.url.xxx.xxxURLContextFactory
will be used. But for Weblogic this does not work. An exception is thrown during
bean deployment -
javax.management.MalformedObjectNameException: ObjectName: Invalid value -> xxx:bean_name
at javax.management.ObjectName.validateAndAdd(ObjectName.java:440) at javax.management.ObjectName.initObjectName(ObjectName.java:409)
at javax.management.ObjectName.<init>(ObjectName.java:254) at weblogic.management.WebLogicObjectName.<init>(WebLogicObjectName.java:196)
at weblogic.management.runtime.RuntimeMBeanDelegate.register(RuntimeMBeanDelegate.java:90)
at weblogic.management.runtime.RuntimeMBeanDelegate.<init>(RuntimeMBeanDelegate.java:83)

Answer 1

This is not an answer on my
question - My questions was: how to force a Welogic EJB Container to BIND EJBean's
home interface to another JNDI Service provider, not Weblogic.
But you wrote how to use JNDI in general - I already know how to use it :)))

Hi
Have a look at the code below
private Context getInitialContext () throws NamingException
String from = "CtxHelper::getInitialContext ";
String webLogicHostUrl = t3://SERVERNAME:9001
Logger.debug(from, "Begin Method", 3);
Hashtable h = System.getProperties();
h.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory
h.put(Context.PROVIDER_URL, webLogicHostUrl);
return new InitialContext(h);
} //end getInitialContext
This way we will get the InitailContext and then do a jndi lookup using
the
Context object as follows
ctx.lookup..........
Now in the above code replace weblogic.jndi.WLInitialContextFactory by
ur
provider.
Hope this helps.
