Datasource Problem - NameNotFoundException

["Perez Pola, Jorge" <jo...@eds.com>]

Hello all,
    
    I got a problem trying to configure tomcat in order to use a Datasource.
 
    The server is running SunOs 5.8. with tomcat 4.1.18
 
    I have this context defined in the server.xml
 

<!--=========================== TEST CONTEXT
======================================== -->
<Context className="org.apache.catalina.core.StandardContext"
crossContext="false" reloadable="false"

   </ResourceParams>
</Context>
<!--  END TEST CONTEXT ================================================= -->

 
Notice that the context also has a Security Realm for logging purposes, and
it works OK
 
Also added to the web.xml 
 
<resource-ref>
     <description>TESTDatasource</description>
     <res-ref-name>jdbc/gmepDB</res-ref-name>
     <res-type>javax.sql.DataSource</res-type>
     <res-auth>Container</res-auth>
</resource-ref>

The code on the class:
 
  Context initialContext = new InitialContext();
  Context envContext  = (Context)initialContext.lookup("java:comp/env");
  dataSource = (DataSource)envContext.lookup("jdbc/gmepDB");
 
The exception:
    
    Name java: is not bound in this Context
    javax.naming.NameNotFoundException: Name java: is not bound in this
Context
 
Clues :
 
        - Classes for oracle : classes12.jar in  CATALINA_HOME/server/lib
      - Security Realm Works 
        - jdk 1.2 (also tried with jdk 1.3.1)
      - I have also tried trying  "java:/comp/env" "comp/env" .... hundreds
con combinations in the lookup, but nothing works.
      
 
 
I have read lot of messages regarding this issue.
 
But anyone could help me or give me a clue, this problem is really driving
me crazy.
 
Thanks in advance,
Cheers.
