Registering datasource in websphere

Question

Hello,
I am trying to implement connection pooling in websphere. I am using version 3.5, alonside db2. I have set up in the datasource in websphere, I then try to use the following code to establish the datasource and retrieve a connection from the pool.
     try {
          Hashtable parms = new Hashtable();
          parms.put (Context.INITIAL_CONTEXT_FACTORY,"com.ibm.ejs.ns.jndi.CNInitialContextFactory");
          Context ctx = new InitialContext(parms);
          ds = (DataSource)ctx.lookup("jdbc/GFSI");
          ctx.close();
          con = ds.getConnection("uname","pword");
     } catch (Exception e) {}
The datasource seems to be set up, but when I try to connect to it, I get an error message saying ..."incorrect database name". I have seen some threads talking about setting up the JNDI name, but I dont where I should be doing this.Any ideas/suggestions gratefully recieved.
Thanks

The code seems to be fine. Problem should be somewhere else. Please check the name of the database that you created on the db2 server and check whether your datasource is pointing to the same database (check the url parameter).Also check whether you have bind the same datasource with jndi name "jdbc/GFSI" in your WAS datasource configuration.
You have :
1) actual database name which is referred by the datasource through the url parameter.
2) datasource name which is the reference for the naming server for binding the datasource with jndi name.
3) jndi name for the datasource which is referred by your code for doing a jndi lookup.
Probably one of the above names is miss-spelled somewhere.
