Using the InitialContextFactory with Sun App Server

[brinker]

Hello everyone,

I have been a long time member of tek-tips, but am fairly new to the J2EE forum.

I am trying to access a Java bean deployed using Sun Application server from outside the container (ie. an external client Java program). There are no jsp pages, just an application client and 1 bean (with home, object, and bean components) The code I am using is below, but it does not seem to work:

InitialContext initialContext = new InitialContext();
String url = "rmi://localhost";
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.enterprise.naming.SerialInitContextFactory"
p.put(Context.PROVIDER_URL, url);
ctx = new InitialContext(p);

// lookup InterestCalculator EJB
Object homeObject =
initialContext.lookup( "java:comp/env/ejb/InterestCalculator"


I was wondering if anybody has a solution to this problem or could provide me with some code.

thanks

Narjit

errors ?

You say you are using the "Sun App Server" - is this the J2EE RI version ? JNDI lookups tend to be vendor specific, and also, in the past I find the java:comp/env var/dir is unforgiving - try leaving it out ...

Thanks for the reply.

I believe the first problem is with the "com.sun.enterprise.naming.SerialInitContextFactory" not being able to be fournd. I believe this is right as I got the code from Sun's web site. Do you know if I need to import anything to get this piece of code to work. I am using a client program to call the beans from outside the container.

thanks

Have you got the J2EE_HOME/lib/j2ee.jar on your CLASSPATH ?

Post the specific error too ...

Yes, the j2ee.jar is definitely in the classpath. The exception I am getting is :

javax.naming.noInitialContextException
cannot instantiate class: com.sun.enterprise.naming.SerialInitContextFactory

I know that this class cannot be found, but I do not know why or how to solve this problem.

Thanks for the article. I'm still combing through it and will let you know if I can figure out something from it.

No success.

It appears as if com.sun.enterprise.naming.SerialInitContextFactory cannot be found. I am curious as whether I am missing something. The container the application is running in on Sun's deployment server is different from the program that the client is using.
