From source file:WeblogicDbServlet.java

public void init() throws ServletException {

    Context env = null;

    Hashtable ht = new Hashtable();
    ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
    //ht.put(Context.PROVIDER_URL,"t3://localhost:7001");

    try {// w ww.  j  a v  a 2s . c  o  m

        env = new InitialContext(ht);
        pool = (javax.sql.DataSource) env.lookup("oracle-8i-athletes");
