Error occurred in call to ORPHCallActivePluginInitialize()

[maniphilip]

Hi..am doing a job that contains an external source stage, an xml input stage and a sequential file stage.
My objective is to read an xml using external source stage , parse the read xml using xml input stage and finally write the parsed xml attributes to a sequential file.
I have been able to read the inpt xml, but am getting the following error when I run the job :

Error occurred in call to ORPHCallActivePluginInitialize()

I have imported the xml definition using Import>Table definitions>Xml Table definitions.

Thanks
Mani
