Hi, try to change the query statements for XPATH statements. Like this: Change this: <copy> | <from part="length" variable="ac3ipRequest"/> | <to part="calarea" query="/area:calculateArea/in0" variable="calculateAreaRequest"/> | </copy> | For this: | <copy> | <from part="length" variable="ac3ipRequest"/> | <to>$calculateAreaRequest.calarea/area:calculateArea/in0</to> | </copy> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4106331#...
