<resource-ref>
<!-- optional -->
<description>
Resource reference to a factory for java.sql.Connection
instances that may be used for talking to a particular
database that is configured in the server.xml file.

<!-- local JNDI name to use in JSPs, servlets, etc. -->
<res-ref-name>
jdbc/phone
</res-ref-name>
<res-type>
javax.sql.DataSource
</res-type>
<res-auth>
Container
</res-auth>
</resource-ref>You'll also need to define a ResourceLink in your Context, that links what you want to call your DataSource locally (used in web.xml, see above) to what you called your DataSource in the admin tool (globally ... these can be the same, but don't have to be). Something like this:
<ResourceLink global="jdbc/phone" name="jdbc/phone" type="javax.sql.DataSource"/>
The 'global' attribute provides the name of the global JNDI resource (what was defined in the admin tool); 'name' provides the name of the local JNDI resource (what will be referenced in web.xml).
That's it! You shouldn't have any problems once you've done this.

I'm using Tomcat 5.0.19. I configured a datasource via the Tomcat Admin tool to configure a datatsource listed below is the server.xml file settings for the datasource
<GlobalNamingResources>

However when I try to access the datasource from a jsp file I get the following error
2004-07-26 10:42:19 StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception
javax.naming.NameNotFoundException: Name jdbc/phone is not bound in this Context
Code snippet listed below
<% InitialContext ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/phone");
Connection conn = ds.getConnection();
try{
Any suggestions on what can be causing this error. Why isn't in the context and how do I bind it to the context?
