Please help with JDBC

Hi all, I'm having a lot of difficulty understanding the way Struts handles
JDBC.  I've got a MySQL database that I can access through JDBC from a
standard Java class, so I know that my computer's configuration, classpath
and drivers are all set properly, but as soon as I add the <datasource> to
my struts-config.xml, I get the following error.  When I run the
DatabaseTest.java class from the command prompt it has no problem accessing
the database, but obviously Struts or Tomcat or one of the parsers is not
finding javax/sql/DataSource.  Can anyone help me get this setup correct?
