Description

Hi there,

I got a similar error with AXIS2-5770 even using version no 1.7.9,
The error was 

java.lang.ClassCastException: org.apache.axis2.saaj.SOAPElementImpl cannot be cast to org.apache.axiom.om.OMElement

The error was on this part

soapBody.addDocument(convertStringToDocument(bodyXml)); 

Any explanation? thanks
