Hi Vishnu,

Most Commony used parsing for implementing java mapping are SAX (Simple Apis for XML) and DOM (Data Object Modeling).

U Use them as per u r requirment.

DOM is comparitively easy to implement as compared to SAX.But when comes to Performance SAX is Far Bettre than DOM for large Messages.

In Java mapping You create Parser Facotry and a Document Object.

you exution starts from execute() Methode (So no Importance of Main method but you can use that for testing porpose.)

For sample you can refer the links given by other frnds.

Thanks

Simple and sweet Solution.

Learn how to read, transform and write XML files using API's and Parser. once you know how to read and write XML file you can easily do java Mapping.

Basically Java Mapping is nothing but a Transformation logic to reform on xml file to other.
