How to tranfer request parameter to another application on the same server

Dear all,

I have two questions :
1) How can I transfer the request parameters to another application on the same server/container ? ( is it possible at all ?)
2) I know for sure this is not possible using only the req/res objects but still, is there a way I can tranfer my request/response parameters to another application on another servlet , without using hidden parameters ?

Please let me know

A few workarounds come to mind.

In some containers it is possible to obtain a RequestDispatcher for a resource in a different web app. That generally needs to be enabled especially; e.g. Tomcat uses the crossContext setting to do that.

Another way -with a number of drawbacks- would be to perform a client-side redirect to a URL that has all the parameters included as GET parameters.

If you have an Apache in front of your servlet container -and know that the request needs to be sent elsewhere before looking at it- then that's what the mod_rewrite module is for.

got you.
Thanks Ulf Dittmer. That pretty much explains my 1 question. Thanks a ton. I know I could never have gotten to it.

I am assuming, that for the question 2. There is infact no other way around other than having a GET method populated with the values/params. Right ?
So all in all, if the other applications servlet takes only a post call. I cannot really transfer any variable to "that" application(servlet). Is my understanding correct ?
