Problem with servlet mapping.
Hello
I am using Tomcat 4.1.24, Win 2000
In my web.xml file I have ...
<servlet>
<servlet-name>
Controller
</servlet-name>
<servlet-class>
sample.Controller
</servlet-class>
<load-on-startup>
-1
</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>
Controller
</servlet-name>
<url-pattern>
/shyam/*
</url-pattern>
</servlet-mapping>
I have restarted tomcat.
Now in my jsp page i am calling a link
<a href=shyam/catalog.jsp>my catalog</a>
Then it should transfer the handling to my controller servlet. which is in
WEB-INF/classes/sample directory
but i see 404 error. Obviously i don't have any folder called "shyam" becas
this i am using only for url mapping.
Please let me know what i am missing??
Thanks & Regards
Pawan

It should work if the JSP URL is in the top-level directory of the web-app.
Otherwise, you need to change your code to something like:
<a href="<%= request.getContextPath() %>/shyam/catalog.jsp">...</a>

Are you sure you didn't have the original URL like the following?....
<a href="/shyam/catalog.jsp">blah</a>
If you did, then you basically hardcoded the URL to point to the root of
the server rather than picking up the context via a relative URL. Or,
another case might be if you used a relative URL ( "shyam/catalog.jsp"
),
but you called this URL from somewhere other than the root of your
context. Either case would have given you a 404 error. Specifically
prepending the context path to the beginning of your URL is the smartest
thing to do since you never have to worry about either of the above
mentioned cases. You always point to the right place no matter what.

Tomcat adds this mapping in its web.xml which your app inherits. It is

Tomcat adds this mapping in its web.xml which your app inherits. It is
probably a matter of a collision of servlet mappings and the .jsp servlet
mapping is winning out.

But in my web.xml i am not specifying .jsp anywhere. I am using url pattern
/shyam/ ... so i thought if tomcat will see any url pattern like this it
will redirect that request to Controller Servlet.

A .jsp file is not a servlet. ".jsp" is already an extension that is
mapped to the container's jsp servlet. Your servlet controller would be
for intercepting servlet requests, not jsp requests. You should be
calling
a servlet and forwarding to a .jsp for presentation, not the other way
around.
