Servlet chaining in different web context

Servlet chaining in different web context

Hi Group

In our project we are making different web modules. All these web
modules are packaged in a form of war files. We have one more web module
which acts as a controller web module which is also packed in a war
file. So we have following files present in the server

WAR1.war

WAR2.war

WAR3.war

WARCONTROLLER.war

The planned flow is, first the user request will hit the controller web
module (WARCONTROLLER.war) and then depending on the some decisions it
will route the request to one of the web module
(WAR1.war/WAR2.war/WAR3.war). In all the war file there is a servlet
which handles the request. So it looks clearly like a servlet chaining
case, where servlet present in WARCONTROLLER.war will chain the call to
other servlet present in different WAR files.

As these servlets are part of their own web context they are invisible
to each other. So how it is possible to do a servlet chaining by
considering the fact mentioned above. We don't want to go for request
redirect thing because that will hit us in performance. As for as
possible this routing should happen inside the server only.

Will you kindly help me to solve this puzzle?
