Hi All,
I am a relative newcomer to Tomcat and Java and I would really appreciate if a
few of you could check my
reasoning here in trying to understand this exception. I am running the
following:
Tomcat 4.1
Apache/1.3.33 (Win32)
mod_jk/1.2.8
JRE Version 1.4.2_03
About every hour or so on the live web app I get the following stack trace
logged to the Tomcat context logger
(Tomcat doesn't hang)
008-04-22 09:06:06 ApplicationDispatcher[] Servlet.service() for servlet jsp

Am I right in saying the following? :
1) These are the the most important entries in the stack trace
----- Root Cause -----
java.lang.IllegalStateException
at
org.apache.coyote.tomcat4.CoyoteResponseFacade.sendRedirect(CoyoteResponseFacade.java:290)
at org.apache.jsp.login_jsp._jspService(login_jsp.java:102)
2) These are the lines from login_jsp.java taken from the /work directory in
Tomcat
101> if(sessionNew) {
102> response.sendRedirect(url_userServletMain);
103> }
So there is a problem with sendRedirect or the parameter url_userServletMain
3) Can anyone tell me if these lines are important or not?
