Conflict Tomcat 4.0.1 and JBuilder useing jsp5

[Reto Gehring]

When I run a jsp with the build in Tomcat 3.2 of the JBuilder 5 everything works fine. (JBuilder Project Properties Server Tomcat 3.2)
If I then run the JSP on my standalone Tomcat 4.0.1 the error message on the bottom apears in my browser after the a POST. ( JBuilder Project Properties Server Tomcat 3.2)
see ==== browser ====
If I put the
throw new JspException("Please enter comment!!");
in comment it works too.
So I switch the JBuilder Project Properties to Srever 4.0
But if I rebuild the project this error message apears in jBuilder: see === jbuilder error ===
It would be so great if somebody knows how to solve this
PROBLEM
Cheers Reto
