I'm having a similar problem. I installed Tomcat4 and
have the examples and struts-example webapps working.
However I can't seem to get my webapp which was
working fine under Tomcat3.2.1 to work. I get the error
listed below when I try go to any *.do. I
My $JAVA_HOME/jre/lib/ext directory is empty.
Anyone have any idea what the problem is?
Here's an abridged version of the error:
