Is this a Bug in request.getServletPath() ?
I'm trying to get a file in the filesystem relative to the location of a
JSP Page. At first Blush the following would seem appropriate:
<%
String jsp_location = application.getRealPath(request.getServletPath());
String relative = jsp_location.substring(0,jsp_location.lastIndexOf("/"));
... get the resource using this path ...
%>
however, when one uses a servlet mapping on a JSP Page like below.
<servlet>
<servlet-name>JSPTestMap</servlet-name>
<jsp-file>/Jaxp/JSPTransformExample.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>JSPTestMap</servlet-name>
<url-pattern>/Jaxp/MapExample.jsp</url-pattern>
</servlet-mapping>
request.getServletPath() returns
<url-pattern>/Jaxp/MapExample.jsp</url-pattern>
and not
<jsp-file>/Jaxp/JSPTransformExample.jsp</jsp-file>
is there any way I can get hold of the original real location of the JSP
Page I'm working in and have it also work with servlet-mappings?

Re: session tracking using URL rewriting & META=refresh
Posted by Srinadh Karumuri <sk...@bbn.com>.
It looks like no one had to deal with this earlier. I made a work around,
not fancy but works.
I used:
<META HTTP-EQUIV=Refresh
CONTENT="600;
URL=../jsp/UserMessage.jsp?jsessionid=To1071mC22961575233267228At&msgid=1001&grace=120;">
and in this page for <form> etc., I used:
<form action=<%= "/jsp/newPage;jsessionid=" +
request.getParameter("jsessionid")%>>

session tracking using URL rewriting & META=refresh
Posted by Srinadh Karumuri <sk...@bbn.com>.
Hi,
I know there are two ways of session tracking in Tomcat 3.
1. Cookies based: This is out of question as our customers do not want this.
2. URL rewriting: We rewrite URLs using encodeURL(...) and worked fine for
more than a year.
The problem started once we introduced the META-Refresh to forward user's
screen after time out when Javascript is OFF. The copy of the HTML source
from browser is as below:
<META HTTP-EQUIV=Refresh
CONTENT="600;
URL=../jsp/UserMessage.jsp;jsessionid=To1071mC22961575233267228At?msgid=1001&grace=120;">
Since semi-colon marks the end of URL, browser was not forwarding the
jsessionid. If I copy the URL into browser manually, it works fine.
Q1. Is there a third way of session tracking? I remember reading somewhere
about keeping an hidden <input> field with name="jsessionid" in the page.
Any help on this?
Q2. I guess tomcat doesn't support any other character in the place of
semi-colon. Is there any way to escape this character in the META value?
Note: We need to use Javascript OFF per customer's requirements.
Thanks,
Sri
