[C2] Almost running on Weblogic 5.1 (Help!)

[EE...@thoughtworks.COM]

I have Cocoon 2 almost running under weblogic 5.1 (on NT4).

I used the following in my web.xml file to pass the classpath to Cocoon:

  <web-app>
      <context-param>
          <param-name>weblogic.httpd.servlet.classpath</param-name>
          <param-value>.......[my path].......</param-value>
      </context-param>

And added the following to CocoonServlet to read that classpath in (note
that this is slightly different than the previously suggested patch for
WL51, which I couldn't get working at all):

        this.classpath = (String) context.getInitParameter
("weblogic.httpd.servlet.classpath");

However, I am still getting exceptions from Cocoon.  Specifically:

What do these mean, and how do I fix them?  Any suggestions?

Thanks very much,
