I am not sure how to add configuration in Oracle App Server. But this how you have to do.
Create a connection object in the app server in the name jdbc/Test . (jdbc/Test is the name of the connection which will be used to get refernece from the JNDI). In the App server you have to create the connection with you userid, password and URL for the connection.
URL - jdbc:oracle:thin:@servername:1521:databasename
You may need to have the connection from EJB or may be from the JSP or bean class. If the connection is required in EJB, then EJB container will get the reference. For JSP or Bean the web container will get the reference. You need to make specific entries in ejb-jar.xml and oracle-ejb-jar.xml (I hope there will be file in this name. Beacause for me I have sun-ejb-jar.xml for Sun App server.) for EJB container and in web.xml and oracle-web.xml for web container.
Here are the entries for web Container -
In web.xml put this entry -
<resource-ref>
<res-ref-name>jdbc/Test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
In oracle-web.xml put this entry -
<resource-ref>
<res-ref-name>jdbc/asta</res-ref-name>
<jndi-name>jdbc/asta</jndi-name>
</resource-ref>
Here is how you will get the connection -
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("java:comp/env/jdbc/Test");
Connection conn = ds.getConnection();
