Basic questions about PL/SQL web services and datasource names

Question

Hi there,
I successfully generated a web service for a PL/SQL packaged procedure in JDeveloper 11.1.1.3.0).
In the web service base class the following code was generated:
__dataSource = (javax.sql.DataSource) __initCtx.lookup("java:comp/env/jdbc/dbconnectionDS");However in the weblogic server the datasource name is jdbc/somethingelse so the deployment fails at first.
What is the recommended procedure to solve this issue? The obvious solution is to manually edit the source -- that is what I did and it worked fine. However if I re-generate the web service I will lose my change. Is there a better way to do this?
Another question -- in the generated web.xml file, there is a resource-ref for the datasource. I was hoping that changing the datasource name there would help but it didn't work. What is it used for in this context?
Thanks
Luis

Hi Vishal,
I did as you suggested but it didn't work... see below more details.
Thanks

1 - I re-generated the web service from the PL/SQL package. The constructor in CFBTestWSBase class looks likes this:
public CFBTestWSBase() throws SQLException
  {  try {
javax.naming.InitialContext __initCtx = new javax.naming.InitialContext();
__dataSource = (javax.sql.DataSource) __initCtx.lookup("java:comp/env/jdbc/custfeedbackDS");
} catch (Exception __jndie) {
throw new java.sql.SQLException("Error looking up <java:comp/env/jdbc/custfeedbackDS>: " + __jndie.getMessage());
}2 - I added the following section to weblogic.xml:
  <resource-description>
    <res-ref-name>comp/env/jdbc/custfeedbackDS</res-ref-name>
    <jndi-name>jdbc/DataSource</jndi-name>
  </resource-description>3 - I got the following error when during deployment to weblogic server:
[HTTP:101216]Servlet: "CFBTestWSPort" failed to preload on startup in Web application: "CustFeedbackTestWS.war".
java.sql.SQLException: Error looking up <java:comp/env/jdbc/custfeedbackDS>: While trying to look up comp/env/jdbc/custfeedbackDS in /app/webapp/CustFeedbackTestWS.war/346617503.
