Servlet communication across web applications

[Surya Kant]

Hi All,
I have two web applications running in same tomcat container.I want to communicate between two web applications using servlets.
I mean servlet1 in web application1 will call servlet2 in web application2.Is it possible??

And one more doubt is..Is session id will be same in both the web applications?

If by "communicate" you mean via HTTP, then you can use the HttpURLConnction class to do that. See e135 and e136 in http://www.exampledepot.com/egs/java.net/pkg.html

The session IDs will be different, because sessions are bound to web apps; they can't be shared across web apps.

Or else you can also use HTTPClient for this ,

One more solution is that Obtain that ServletContext (The context name of that web application which you have defined in server.xml file) and put cross-context is true .

Or you can figure out if the reason you need to communicate is because the apps should be one? Or there's code that should be in each app?

Cross context stuff may not be portable on other servers.
