I need some standard way for communicating jsp and ejb
with xml.

The scenario is where 80 jsp's communicating to 25 ejb's.
       
      Request xml
user<------->jsp's<----->xmlconvertor<----->EJB's

All 80 jsp's will communicate with ejb thro' xml and
within ejb communnication i will use java varables.

Do u have pattenrs,tecniques etc to achive this.
