Here is the sample code for ur reference...

<?xml version="1.0" encoding="UTF-8"?>

<ns0:MT_SOAP_Sender xmlns:ns0="http://sdn.com/XI/Demo/SOAP2File">

<Customer>

<Fname>AAA</Fname>

<Mname>BBB</Mname>

<Lname>CCC</Lname>

<CustID>12345</CustID>

<Address>ADD1</Address>

</Customer>

<Customer>

<Fname>XXX</Fname>

<Mname>YYY</Mname>

<Lname>ZZZ</Lname>

<CustID>12345</CustID>

<Address>ADD2</Address>

</Customer>

<Customer>

<Fname>RRR</Fname>

<Mname>SSS</Mname>

<Lname>TTT</Lname>

<CustID>12345</CustID>

<Address>ADD3</Address>

</Customer>

</ns0:MT_SOAP_Sender>

Hi sankar,

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 best solution 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 http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Document.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/package-frame.html /people/prasad.ulagappan2/blog/2005/06/29/java-mapping-part-i

/people/prasad.ulagappan2/blog/2005/06/29/java-mapping-part-ii /people/prasad.ulagappan2/blog/2005/06/29/java-mapping-part-iii

If you want you can also send java code as payload to do mapping in XI. For this go through the url:

Hi,

You need to have aii_map_api.jar in XI server and for Java mapping you must define a Java class that implements the Java interface After creating java program zip this file along with the class file and import it into XI Integration Repository as 'Imported Archives' under the mapping objects .After that create the Interface Mapping

These weblogs would help you
