           Summary: jsp exception handling
           Product: Tomcat 5
           Version: 5.0.28
          Platform: All
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Jasper
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: shengshen@gmail.com


I use the following directive
<%@ page errorPage="/jsp/error.jsp" %>
to tell jsp to move to error.jsp when exception raises on the page.

But I noticed the the real behavior relates to the "position" that the 
exception raises on the JSP page: 
1.When it raises on the relatively front part of the page, the page is 
redirected correctly to /jsp/error.jsp 
2.if exception raises at relatively rear position, the contenct of 
the /jsp/error.jsp is outputed right after the normal output of the page. 
3.If at even rearer position, the result is a weird "chopped" page with only 
part of normal output.

I tried to debugged the src of jasper into PageContextImpl's 
doHandlePageException method. Found that the situation 2 was caused 
by "JspWriterImpl has already flushed", the situation 3 was caused by 
the "response was already committed".

I can't understand this behavior of tomcat. Isn't it puzzling to the ones that 
want to debug JSP page?
