Trying to get datasource receive NoClassDefFound error

 Hello everyone,

We are trying to get a datasource using the following code:

            Connection cConnection = null;

            Hashtable ht = new Hashtable();
            ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
            ht.put(Context.PROVIDER_URL, t3://10.1.15.22:80);  
            Context ctx = new InitialContext(ht);
            javax.sql.DataSource cDataSource = (javax.sql.DataSource) ctx.
                lookup(sDataSourceName);
            cConnection = cDataSource.getConnection();

When we do the call to getConnection we get the following exception:

java.lang.NoClassDefFoundError: weblogic/rmi/internal/Stub

Is anyone else experiencing the same problem?

Thank you in advance for any help.
