Hi Sabbir,

This is chandrasekhar,I have done few Mapping Scenarios using java mapping.

Steps:

1)you need to use any parsing Technique either DOM Or SAX.

2)Develop your java class with out main method in Netweaver Developer stdio.

3)Need to create a jar file in the Cmd(commond line promot.

Commond for creation of jar cf name.jar filename.class

4)import your jar file in to IR.you can see Imported Objects under software component.Right click on the Imported Object and select New and enter the name and browse your jar file and select the corresponding jar file which you created and click save and activate.

5)when you are doing Interface Mapping you need to select as Java calass and select the Mapping program and after the process is same as normal.

If you have any doubts please let me know.Hope my answer will reach make you understand better.

Thanks and Regards,

HI

No, there is no tool for generating code for mapping,even if tools are there it depends upon once own logic.

So we use SAX and DOM parsers for the java mapping.

SAX can be used to read an XML file and DOM can be used to build an XML file.

Building DOM Trees from a Document :
