Hi ,

The java concepts that are majorly used in XI are :

1. SAX / DOM Parsing of XML data [Java XML parsing techniques]

2. EJB Concepts [XI Adapter module / Adapter / Java Proxy development]

3. User defined functions with Graphical mappings.

I guess the tutorials offered by Sun microsystems would be of great help if you are serious about it

http://java.sun.com/docs/books/tutorial/

Just giving you a little more info on java mapping as it would be quite offten used....

Java Mapping uses 2 types of parsers. DOM and SAX. DOM is easier to use with lots of classes to help you create nodes and elements, but , DOM is very processor intensive.

SAX parser is something that parses your XML one after the other, and so is not processor intensive. But, it is

not exaclty easy to develop either.
