Empty URL redirection issue in jsp

[Ratheesh Kamoor]

I need to redirect http://mywebsite.com/?bannerId=12332 to a specific jsp

For that I created a url pattern as
<servlet>
<servlet-name>lostdocsJSP</servlet-name>
<jsp-file>/index.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>lostdocsJSP</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

It is redirecting above URL to index.jsp , but all other requests for images, swf, xml also getting redirected to this JSP , How can I avoid this issue in WAS 6.1
I know that in Tomcat I can define a default URL pattern to bypass any unwanted requests, but it is not working in Webshpere.

Tomacat :
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>.jpg</url-pattern>
</servlet-mapping>

you need to change url-pattern.
<url-pattern>/*</url-pattern> will forward all requests to jsp, change it accordingly.

[Bear Bibeault]

Of course if you tell it to send all requests to that JSP, it will!

What are you really trying to accomplish?

If any one typed as http://mysite.com/?bannerId=1234 , then this request should go to index.jsp. I dont want any other request to go to index.jsp
How can I achieve that.

Just set the welcome page to index.jsp. It should work. Something likes

<welcome-file-list>
  <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

Thanks Duc Vo, I know that I can use welcome file . But when I use this option I am loosing query strings (Eg: bannerId = 123) when i read it from index.jsp.. What should I do to retain all query strings as it is ?

Ah, you shouldn't use query string. Should use request.getParameter(). I.e.

String bannerId = request.getParameter("bannerId");

Then it should work.

can you give some more details?

i guess , before index.jsp, you want to do some logic in servlet and then you want to pass the parameter to the index.jsp right? if yes,

then choose some particular servlet instead of /* .

Thanks, getProperty is working as expected
Thanks again
