Communicate between two struts apps

[Wen-Jung Chen <we...@gmail.com>]

Hello,

We have two struts applications which are planning to be created as two war
files and deployed as one ear file on application server. We develop one
struts app and other team develops another one. The requirement for us is
their struts application will call our action method to invoke a window on
our side. Does anyone know how their struts app can invoke our action
method? I was told that they can use url redirect by using url we provided
so we can popup a window for them. Is this right way to do it? Is there any
other better way to handle this since we are located in two different jvm?
And also if we want to  pass data back so they can display message on their
screen, are we still use same way such as url direct to pass data as request
parameter to them?

Please help.

Thanks,
Wen-Jung
