Migration To JRun 4

Question

My project is trying to migrate to JRun 4.0. JRun indicates
the following servlet mappings are not supported in JRun 4:
*.jrun = invoker
Can anyone tell me the new servlet mapping options to use
instead of *.jrun? Currently we are using servlet mapping *.jrun to
point to the servlet-name defined in our web.xml. Here is an
exmaple of one of our JSP files:
<form name="frm" method="post"
action="controller.jrun">
Here is a web.xml:
<web-app>
<servlet>
<servlet-name>controller</servlet-name>
<init-param>
<param-name>env</param-name>
<param-value>dev</param-value>
</init-param>
<servlet-class>EvaluationServletController</servlet-class>
<display-name>ServletController</display-name>
<description></description>
</servlet>
<welcome-file-list><welcome-file>login.jsp</welcome-file></welcome-file-list></web-app>

Answer 1

From the version jump (2.3 -> 4) and the context in the
stacktrace, I would say you are using unsupported jsp syntax --
something that was accepted in 2.3 and has since been removed. Can
you post the first few lines of the .jsp page?
