how to communicate between 2 servlets which are present in two different web applications

hi every one,

how to communicate between 2 servlets which are present in two different web applications?

case1: two web applications are deployed in the same server (for example tomcat)
case2: two web applications are deployed in two different servers (for example tomcat and weblogic)

need help

Java is loaded with tools for communicating between applications. One of the simplest would be a shared database.

What are the characteristics of the data which needs to be shared?
volume?
rapid change?
transactions?
... etc

Bill

actually i was asked this in an interview ....

You can get the ServletContext of another application running in the same server using getContext(String appUrl):

http://tomcat.apache.org/tomcat-5.5-doc/servletapi/javax/servlet/ServletContext.html#getContext%28java.lang.String%29

Can you not try opening a HTTPURLConnection to the other servlet ?
