App Server 8.1 JDBC Connection problem

Question

Dear Expert,
Cu are using Sun Java System Application Server Enterprise Edition 8.1. Cu created one jdbc connection pool and datasource. They are called
jdbc/RM
From the App Server Admin Console -> Connection Pool, cu can "Ping" the database via the connection pool.
Cu did the configuration on web.xml and sun-web.xml
web.xml
<resource-ref>
<description>Oracle Database Connection - Rawmart</description>
<res-ref-name>jdbc/RM</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
sun-web.xml
<resource-ref>
<res-ref-name>jdbc/RM</res-ref-name>
<jndi-name>jdbc/RM</jndi-name>
</resource-ref>
In customer class,
220: protected void initDataSource() throws NamingException {
221: initContext = new InitialContext();
222: envContext = (Context) initContext.lookup("java:comp/env");
223: String dataSource = rConfigObject.getConfigValue("DATASOURCE");
224: rDataSource = (DataSource) envContext.lookup(dataSource);
225: }Exception occurs on line no. 222 already.
From server.log, we get
================

Do you have any ideas on this problem? Thanks.

Answer 1

Try asking the Customer to fire up the JNDI browser in the admin console and try to browse the JNDI tree.
What class is the InitialContext.lookup() happening in? Is that getting executed in the servlet class or a standalone client?
thanks.
