[c2] class loading problem with a jdbc driver

[HALLOWELL,KARL (HP-Cupertino,ex1)]

I'm having trouble specifying the classpath for a jdbc driver. Here's the
entry in my web.xml file for loading the jdbc driver:

    <init-param>
      <param-name>load-class</param-name>
      <param-value>
        <!-- For Oracle Driver: -->
          oracle.jdbc.driver.OracleDriver

        <!-- For Database Driver: -->
        org.hsqldb.jdbcDriver
      </param-value>
    </init-param>


I get the following exception first thing (no previous entries in the log
file) when I start cocoon. Immediately after the (long) load class
exception, the log file prints out the full classpath including the jdbc
driver (it's
"/opt/jakarta-tomcat-4.0-b5/webapps/cocoon/WEB-INF/lib/classes12.zip"). Why
isn't the class being found (it gets found later when I load relevant
esql-based xsp pages)? What am I doing wrong?
