Unable to perform an Assign using XPath 1.0 Expression: Getting
Assignment Mismatch error
Hi,
I am trying to execute a simple BPEL script that is copying from one element
to another (from input to result). When I execute the script I get tan
assignment mismatch error indicating that the Xpath failed to find a match.
I am currently using Apache Ode 1.1.1, running within Apache Axis 1.3/Tomcat
6.
BPEL Script:
