Thanks all, I think I have found the problem. It appears that the JRun 2.3.3
webserver that I was using was configured incorrectly.
In the mapping table used by JRun the following was found.
*.jsp Invoked: jsp
*.jsp10 Invoked: com.livesoftware.jsp.JSPServlet
I renamed the "thepage.jsp" to "thepage.jsp10" and everything started working as
stated. What the difference is I am not sure (maybe something to do with the jsp
version). I appreciate all the help and information everyone provided. Hope I can
do the same in the future.
