Iam trying to do a java mapping

Exception recevied is Application mapping program com/al/credtosap/GenCredential throws a stream transformation exception: GenCredential:execute:Praser failedFor input string: ""

can some body give inputs please

[stefan_grube]

Test your Java mapping stand alone first:

If you run your mapping on the server, make sure that the required library are uploaded at external program in the same SVWC and namespace. (com.al.credtosap)

Hope that helps
