cannot find variable UPDATED_CONTENT whie deploying WshSendOtmDocument.bpel process

Hi All,

I am currently working on POC for EBS-OTM Integration. I have taken the code for two BPEL processes 1.PoSendPoToOtm
2.WshSendOtmDocument

here first process is calling second process. while compiling the second process got compilation errors in RestInvocation.java code even i had added the library xmlparserv2.jar in the properties of the project.

Any help is appreciated.
