Convert the Input xml to String

Hi Folks,

Currently I'm working on a PROXY to SOAP scenario. The input of the target structure is a string. In this case i have to do such a mapping that i can map my structure to the string. I'm folowoing the below wiki.

https://wiki.sdn.sap.com/wiki/display/XI/JavaMapping-ConverttheInputxmlto+String

But I have 2 problems with this wiki:

1. I don't know how to use this piece of Java Code

2. Here I'm not using any source file, the input will be from the ABAP Proxy directly. So how I can provide the input to it ?

Regards,

Santosh
