JNDI Error

Question

Hi Vicky,
Whn i keep Web tier and app tier in the application server itself, i am getting the bean reference. but its not in the case of web server to app server.
Web server(JSP, Custom tags) --> Application Server(EJB) --> Data Base.
In this case im not getting the bean reference and the initial context values.
The following code im written in the JSP Page
InitialContext ctx;
Context environment;
Properties prop;
try
String initCtxFactory = getInitParameter (Context.INITIAL_CONTEXT_FACTORY);
String provideURL = getInitParameter(Context.PROVIDER_URL);
prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, initCtxFactory);
prop.put(Context.PROVIDER_URL, provideURL);
ctx = new javax.naming.InitialContext(prop);
common.DBHome home = (common.DBHome)ctx.lookup("java:comp/env/ejb/DBHome");
common.DB stoProc = home.create();
}catch(Exception ex)
System.out.println("Exception Error " + ex );
Thanks
Jai

Hi Jaya,
Have you tried using EJB References?
For using the 'java:comp/env' context for lookup, you will have to create ejb references in your deployment descriptors using <EJB-REF> tags.
The structure of EJB-REF tag is as follows:
     <ejb-ref id="EjbRef_1">
          <description></description>
          <ejb-ref-name>ejb/DBHome</ejb-ref-name>
          <ejb-ref-type>Entity</ejb-ref-type>
          <home>com.ex.ejb.DBHome</home>
          <remote>com.ex.ejb.DB</remote>
</ejb-ref>
The application server binds the references to the correct JNDI names at runtime.
