Mohan,

To assign points you need to create your thread as question, which you select using a checkbox.

In the link I sent , it contains all the tutor files. You need to download tutor software which you can find it on the same page.

Thanks,

Raj.

Hi Mohan,

In Java Mapping, you parse the source XML structure using DOM parser or SAX parser.You would find all the classes methods etc to go about learning and implementing the java mapping using either of the parsers at sun.java.com, one such exhaustive resource can be found here:

http://java.sun.com/webservices/docs/1.1/tutorial/doc/

http://help.sap.com/saphelp_nw04/helpdata/en/e2/e13fcd80fe47768df001a558ed10b6/frameset.htm

To give you a brief idea about how to go about java mapping, these are the steps you would be doing:

You need to have NWDS installed on your system. Once this is done these are the steps you need to follow to write the program and to be able to use it in the directory:

1. Write your java program.You need the libraries aii_map_api.jar and inqmyxml.jar.You can use SAX or DOM for navigating through the source XML and creating the target XML.

2. Create Jar file. After compiling your program, you have to create a jar file. The content of the jar file have to be all classes and libraries you need for the mapping program to run.

3.Load the JAR file into the IR.Go to the Integration Repository. Under your Software Component and Namespace you create a new Mapping Object ‘Imported Archive’. Inside this object you upload the jar file.

4.Attach Java mapping to an interface mapping.

Create a new Mapping Object ‘Interface Mapping’, chose the interfaces you want to map. To attach the Mapping to the request or response, use ‘value help’ and chose ‘Java Class’. Chose the Java Class with the corresponding mapping. After saving and activating the change list, you will be able to use the Mapping in the Integration Directory.
