Ashok,

Try this:

ctx.lookup("java:comp/env/MLJNDI");

If your program is in an EJB project, you have to do additional configuration in the ejb-jar.xml file.

<b>EJB project -> ejb-jar.xml -> session beans -> resource-ref</b>

Add a new entry in resource-ref for MLJNDI such as the following:-

Resource Reference Name: <b>MLJNDI</b>

Resource Type: <b>javax.sql.DataSource</b>

Resource Authentication: <b>Container</b>

Resource Sharing Scope: <b>Shareable</b>

Hope it helps,

Ashok,

Just to add, I'm not sure if you have access to the servers J2EE Visual Admin. If you do, open up the server --> services and click on JNDI Registry.

You should walk through this just to get a feel on how SAP sets up there naming registry. It is diffinetly not the same as weblogic or tomcat.

Try:

ctxt.lookup("jdbc/MLJNDI");

Hi Ashok,

Replace : by / in your lookup expression.
