Java Mapping sample code

HI all,

I want to learn how java mapping can be done in XI.

I have created a javaMapping class implements StreamTransformation .

I am not getting what code should be written in execute method. I have included all the jar files required.

Please can anyone give me a sample code that should be written in execute method for a simple Message mapping.

I presume we use jaxp Api for that,but I am not getting the exact way to proceed further.

Thanks
