java mapping issue
Hi
I am following http://www.riyaz.net/blog/xipi-java-mapping-demystified/technology/sap/415/
and have written a sample java mapping code...but am getting the error " XML not welformed " content not allowed in prolog while testing the Operation mapping...
what may be the issue ??
