Tomcat 5.5 redirect vs. forward behavior with welcome-file-list
In Tomcat 4.1, a request to a directory containing a welcome-file would
*redirect* the user to a URL with any applicable welcome-file's name
appended. In Tomcat 5.5, the request is instead *forwarded* to the welcome
file.
Is there a way to make Tomcat 5.5 act like Tomcat 4.1 in this respect?
For example:
I have a web.xml which contains:
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
In Tomcat 4.1, a request to http://www.mysite.com/directory/ makes the
browser refresh with a URL of http://www.mysite.com/directory/index.jsp
In Tomcat 5.5, the same request leaves the browser with the same URL
http://www.mysite.com/directory/.
BACKGROUND:
I'm using Tomcat 5.5.17 on Windows XP, and unfortunately, my application is
dependent on the redirect behavior of Tomcat 4.1 because my JSPs use
HttpServletRequest.getRequestURI() to find the name of the JSPs themselves.
The JSPs pull their content from the database based on the URL being
requested. So, if the browser's URL bar reads
http://www.mysite.com/directory/index.jsp, the 'index.jsp' queries the DB
for content based on the path '/directory/index.jsp'. Conversely, if the
browser's URL bar reads http://www.mysite.com/directory/, the same JSP looks
for database rows using the path '/directory/'. Naturally, because Tomcat
5.5 acts differently, similar requests receive different content.
I realize that populating content based on what's in the URL bar is not the
best design, but I can't seem to find another way to definitively get the
name of the actual JSP being requested. If anybody knows of a method similar
to getRequestURI(), but which knows the name of the JSP being requested, it
would help tremendously.
Thanks,
Todd

By the way Todd. Use HttpServletRequest.getServletPath() instead of
HttpServletRequest.getRequestURI(). This will report the forwarded path
without the context path information.

Hi Todd,
I don't know if their is some configuration attribute but a servlet
filter could be an option.
Good luck

Hassan,
I couldn't seem to get
request.getAttribute("javax.servlet.forward.servlet_path") to work in my
situation (it returns null, maybe because its being called from a custom
tag?), but Stefan's suggestion of request.getServletPath() accomplishes just
what I need.
Thank you for your response, and to Stefan as well,
Todd

TSSIYF -- The Servlet Spec is your friend :-)
SRV.8.4.2 Forwarded Request Parameters
Except for servlets obtained by using the getNamedDispatcher
method, a servlet that has been invoked by another servlet using
the forward method of RequestDispatcher has access to the path
of the original request.
The following request attributes must be set:
javax.servlet.forward.request_uri
javax.servlet.forward.context_path
javax.servlet.forward.servlet_path
javax.servlet.forward.path_info
javax.servlet.forward.query_string
HTH!
