ERROR WHILE USING XSLT MAPPING IN INTERFACE MAPPING

Hi,

We are using an xslt mapping in our scenario but while i load the XSLT mapping in the interface mapping i get a message :

Transformer configuration exception occurred when loading XSLT

sorce interface :outbound and asyncronous.

mapping : XSLT mapping (imported as a zip file)

target interface: abstract,asyncronous.

The xslt runs well in standalone and its well formed and there is no name space issue.

please help if any one has faced such a situation while using XSLT mapping.

regards,

Anirban.
