Multiple Url Patterns

[Jonathan Holloway <to...@eudoramail.com>]

I have a number of servlets deployed in a web application under tomcat,
one of these servlets is specifically accessed as follows:

http://localhost/servlets/exampleServlet

My problem is that I need to access exactly the same servlet but using a 
different
url pattern, i.e. this one

http://localhost/exampleServlet

Is it possible to deploy a servlet under two pattern. i.e. as follows in 
the web.xml
file under the servlet mapping..

<servlet-mapping>
    <servlet-name>exampleServlet</servlet-name>
    <url-pattern>/servlets/exampleServlet/*</url-pattern>
    <url-pattern>/exampleServlet/*</url-pattern>
</servlet-mapping>

I've tried it like this but have been unable to get it to work and I need 
to do this for
backwards compatibility onyl.   Is it possible to do this any other way if 
not possible
in this way?

Does it matter if you get two instances of the same servlet? If two
instances is ok then you can include two <servlet></servlet> sections
using the same servlet-class but different servlet-name and map these two
two different URLs.

The Deployment Descriptor DTD seems to allow only one url-pattern in
servlet-mapping (reading the servlet 2.2 spec).

You cannot do this in one mapping, but you can do it in two:

  <servlet-mapping>
    <servlet-name>exampleServlet</servlet-name>
    <url-pattern>/servlets/exampleServlet/*</url-pattern>
  </servlet-maping>

  <servlet-mapping>
    <servlet-name>exampleServlet</servlet-name>
    <url-pattern>/exampleServlet/*</url-pattern>
  </servlet-mapping>

There's no limit on the number of different mappings you can point at the
same <servlet> definition.
