When you say normal context, what are we talking about? :) Are talking about something like:
<!-- Tomcat Examples Context --> <Context path="/examples" ........ blah, blah, blah. <******snip********> <Resource name="jdbc/EmployeeAppDb" auth="SERVLET" type="javax.sql.DataSource"/> <ResourceParams name="jdbc/EmployeeAppDb"> <parameter><name>user</name><value>sa</value></parameter> <parameter><name>password</name><value/></parameter> <parameter><name>driverClassName</name> <value>org.hsql.jdbcDriver</value></parameter> <parameter><name>driverName</name> <value>jdbc:HypersonicSQL:database</value></parameter> </ResourceParams> </Context> Thanks,

Are you declaring the JNDI resource in DefaultContext or with ResourceLink? if yes, try with a normal Context and Resource.

Yeah I had already tried that. When It was not there I got this message
on
Tomcat startup - java.lang.reflect.InvocationTargetException: java.lang.NoClassDefFoundError: javax/sql/DataSource
I'm kind of stumped on this. Any other ideas?

If you use oracle jdbc driver, put classes12.jar in common/lib

I know I have the Oracle jar in the right place because I get this msg
when
if I don't have it in <tomcatHome>/common/lib.

I googled for this answer. The most common problem is not finding the database driver in <tomcatHome>/common/lib.
