在struts动作中间调用远程servlet

Question

Is it possible to call a remote servlet in the middle of a struts action and then use its result?

For instance, say i have two webapps A and B on the same server

Webapp A has an action which i would like to do something like:

processing
"call" servlet in webapp B
process using response from remote servlet
forward to whatever page is appropriate (success/error/etc)

In my specific example the servlet in webapp B will generate a PDF file which is returned in the response and i need use this pdf file in the further processing in the action in webapp A.

So i would like the call to the servlet to be like calling a method that returns what i need for further processing if possible.
