Hi, We are working of integration with TIBCO and we are facing and issue interms of datatype of the elements sent to TIBCO.

We have built the stub classes and are invoking them, we are getting the response as System.CalloutException: Web service callout failed: WebService returned a SOAP Fault: Internal Error faultcode=SOAP-ENV:Server faultactor=. We have passed all the mandatory parameters but still getting this error.

 What might be the possible reasons for getting this error, any info will be helpful.
