I am literally for this.

I placed db2java.zip under jboss-lib folder. and here is my ds-file details

<?xml version="1.0" encoding="UTF-8"?>

<!-- See http://www.jboss.org/community/wiki/Multiple1PC for information about local-tx-datasource -->
<!-- $Id: db2-ds.xml 88948 2009-05-15 14:09:08Z jesper.pedersen $ -->


<datasources>
<local-tx-datasource>

here is my jboss-web.xml

<jboss-web>
<resource-ref>
<res-ref-name>jdbc/myDataSource</res-ref-name>
<jndi-name>java:jdbc/myDataSource</jndi-name>
<res-type>javax.sql.DataSource</res-type>
</resource-ref>
</jboss-web>
---------------------------------------------web.xml---------------------------------
Here is my web.xml resource-ref

<resource-ref>
<res-ref-name>jdbc/myDataSource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Application</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
---------------------------------------------web.xml---------------------------------

DB Code for fetching connection.

InitialContext ic = new InitialContext();
dataSource = (DataSource) ic.lookup("java:comp/env/jdbc/myDataSource);
conn= dataSource.getConnection();
System.out.println(" DataSource NAME in try using JNDI:"+dataSource);


I am getting the below exception.

I don't use DB2 so I don't know what the connection URL should look like, but this error means that the BD2 JDBC driver didn't like the connection URL you specified. Go back to the DB2 JDBC driver documentation and figure out what the connection URL should be.
