Hi;

You waill have a natural benefit to work on XI as you are aware of JAVA.

You can learn ABAP as you move on to develop few interfaces.It is not prerequisite to have ABAP skilly but its an add on adavantage.

Dear Gabriel,

pls help me whether it is necessary to have to gather full knowledge ABAP????

There is no need of full knowledge of ABAP ....If you have knowledge that would be added advantage for you. As you told that you are from J2EE background.....so you can do JAVA MAPPING very easily

go through the following blogs which are developed based on JAVA concepts...then you will understand the POWER OF JAVA in SAP XI.

<u><i><b>JAVA in xi</b></i></u>

A very important place where you will use JAVA in XI is while doing your Mapping. There will be cases when JAVA MAPPING is the bestsolution to go for. There are 2 types of Parsers available for JAVA Mapping. DOM Parser and SAX parser. Just got through the following links to understand more on

Java Mapping and the APIs available.http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/parsers/package-summary.html

For this go through the url: /people/sap.user72/blog/2005/12/14/sending-java-code-as-payload-to-do-mapping-in-xi

Understand

What is ALE-IDOC?

What is RFC? and BAPI

That is more than enough.

Hi,

I'd suggest buying some ABAP books (about ABAP and XML):

http://www.amazon.com/XML-Data-Exchange-Using-ABAP/dp/1592290760

or this one for RFC

http://www.sap-press.de/katalog/buecher/titel/gp/titelID-906
