Hi Ahmad,

As you mentioned you have good ABAP background,As per as I know a XI develper need to use java always...there are few situation in typical mapping situation you will be going to java mapping or abap mapping.

If you know core java is enough to move to XI and later you can learn slowly the advanced topics.

There are so many of them in the market who are working in XI without having knowledge of java.

Please start learning XI and become XI devloper.

Please let me know if you have any queires.

Thanks and Regards,

Chandu.

Ahmad,

Java will be useful when you need to write UDF's , Java Mapping , Adapter Modules etc.

It is not a absolute must , but it sure is very handy.

Knowing Core java is sufficient in most cases except when you need to develop modules ( EJB knowledge is helpful here ) or when developing custom adapters.

Goto https://www.sdn.sap.com/irj/sdn/developerareas/xi and look at the featured Blog section. It links to 3 diff. weblogs that will give you a fair good idea on how much of what is required for XI !!!!

Maybe you shoudl start with - http://java.sun.com/docs/books/tutorial/

Main focus should be on string functions cos that is what we usually manupulate in XI while writing a UDF.

In case of java mapping, look into

SAX - http://www.cafeconleche.org/books/xmljava/chapters/ch06.html

DOM - http://www.cafeconleche.org/books/xmljava/chapters/ch09.html

Hi Ahmad

You are correct ...Java will be help you lot in XI in particular mapping and modules

And in addition to above res…

Start up with Core Java like

1) OOPS very basics

2) Exceptions

3) Collections

4) I/O Streams

Just read theory on this try to look at the existing examples then go practicing you own examples

Links : www.java.sun.com

www.java2s.com

The above links will alomst all the information about Java

This will be enough for Mapping UDF in XI

But if want write your own modules then you should know some extend J2ee(EJB)

it will take little time and practice...but If know Core Java rest all easy

I hope this will help you
