My company has bought JRUN4.0 and migrate some JSP from tomcat to it. However, I get problem when run the web. I hope someone can help me. I had some values (context parameter) in the web.xml and want to get them from the JSP. However, the JSP can't get the value. The Jrun shows that can't find the method and the system can't retrieve the value of SESSION_N with return null. I can get the value in tomcat but not JRun. What's the problem?
