Can a URI pattern be matched to a JSP?
Hello everyone:
I am using Tomcat 4.0.4 on IIS. I would like to know
if there is a way of forwarding requests of a
particular pattern to a JSP i specify using Tomcat?
For eg. say the user requests for a file like
/examples/dln/sample.doc I want tomcat to forward the
request to a JSP /examples/index.jsp instead of
serving the file out. I guess this is similar to what
servlet mapping is! A particular URI pattern
'/examples/dln' should be forwarded to a particular
JSP '/examples/index.jsp'.
Any advice and assistance on this would be very
helpful.
Thanks
Prashanth
PS: It's nice to be back in the list!

Duh! figured it out.....I copied the web.xml file from
/conf into my web application's WEB-INF folder. Since
this contained a default mapping, there was a
duplicate..... I created a new web.xml file for my
application and it works now!!
Thank guys

Re[2]: Can a URI pattern be matched to a JSP?
Posted by Eric Everman <ev...@precedadesign.com>.
Also, is it possible that there is another servlet named
'default'? Actually, did you say this was *your* web.xml file - not the
default one located in the root/config directory?
If this xml snippet is from root/webapps/<yourapp>/WEB-INF/web.xml file, it
will be additive to the root/config/web.xml file which contains the default
servlet declaration unless you have modified this file. In other words,
everything in your root web.xml file is already included, you don't need to
"re-included" it in your application's web.xml file.
Does that help?

Hello Prashanth,
are all your <servlet> entries *after* <context-inint> entries and
*before* <servlet-mapping> entries?
Take a look in the dtd and double check that you have everything in
the proper order.

RE: Can a URI pattern be matched to a JSP?
Posted by Stefan Langer <ma...@web.de>.
Hello
Your logfile says that default is not a unique name meaning some other
servlet has the same name.
The best way to handle these issues is to eliminate everything from your
web.xml that is not explicitly yours. So just add your servlet and your
servlet mapping to your web.xml and delete everything else since it should
allready be included in the default web.xml.

Re: Can a URI pattern be matched to a JSP?
Posted by Prashanth Pushpagiri <pr...@yahoo.com>.
Hi:
When I startup tomcat I still get the following error:
ERROR reading java.io.ByteArrayInputStream@d2fc36
At Line 63 /web-app/servlet/
Inside my web.xml file I found the following:
<servlet>
<servlet-name>default</servlet-name>
<servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<init-param>
<param-name>listings</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
the </servlet> tag is line 63. I placed the servlet
tag above and below the default servlet....does not
help! Could there be a conflict? What more information
can I provide to debug the situation? This is one

This doesn't mean it's not working, you need to figure out what's
causing this error, maybe it's something totally unrelated. And is
that the entire error message? It looks incomplete.

At this point, I'm not sure I'm going to be able to help you anymore,
sounds like you've got a different problem. And you're going to need
to provide more information in order for people to have an idea what's
going on.

Hi:
I tried this but when I add the servlet and
servlet-mapping tags to the web.xml, Tomcat throws an
error during startup!
ERROR reading java.io.ByteArrayInputStream@76cad3
At Line 57 /web-app/servlet/
I tried adding the mappings to web.xml files in /conf
and my web application...neither a success..
Am I doing something wrong? All I want to do is send
the request to my index.jsp page which will check for
something and then serve the file out!
Thanks

Yes, you can do this.
Just define a servlet in your web.xml, and instead of specifying a
servlet-class, specify a jsp-file. Then you can specify
servlet-mapping's back to that servlet. A la:
<servlet>
<servlet-name>somename</servlet-name>
<jsp-file>index.jsp</jsp-file>
...
</servlet>
<servlet-mapping>
<servlet-name>somename</servlet-name>
<url-pattern>/dln</url-pattern>
</servlet-mapping>
(You used to be able to specify the jsp-file right in the
servlet-mapping -- i.e. instead of the servlet-name -- but it looks
like that was changed in the 2.3 spec. I think the above gives the
same effect, just with the extra expense of having to come up with a
servlet name :-).
