Mapping in integration server

Question

Hi Experts,
Between Java and abap mapping ,which is faster and recomended.
In which stack(ABAP/Java), mapping is happened.
As per my knowwledge,Integration engine runs on java server and mapping editor is a java application and graphical mapping is also a java application.
So does integration server pass the control to java stack for mapping in pipeline process.
Please help me out........

Hi,
Java mapping will be faster than ABAP mapping

I think Java is better than ABAP for mapping, and if you can XSLT is the best.
You can test your Java mapping in your JDE (Eclipse) and it is more friendly than the ABAP debugger.
Java provide a very large API, I am not sure ABAP API too.
About transport system: Java is transporting with your Repository development, so you don't need to do anything more.
I think you must use ABAP mapping only when you can't do XSLT or JAVA mapping. For example when you want to use FM.
Java has better IDE tools than ABAP, and has a richer API library.
If you have a java version management system in place, such as sourcesafe, cvs, or SAP JDI, that won't be a problem.
Another issue with ABAP mapping is the performance. Natively, XI uses java mapping since that part is built on Java stack. When ABAP mapping is used, it has to make a RFC call from Java to ABAP stack which consume some resources and time.
For ABAP mapping you need to use

I suggest you also go through these links to know more on ABAP Mapping:

Refer to following SDN Demo which explains the need and how to do the ABAP mapping.
