com.oracle.bpel.client.BPELFault selectionFailure

the entire error message was:

going in the BPEL Instance flow trace, the actual error is traced:

Error in evaluate from expression at line "151". The result contains 5 nodes for the XPath expression : "/ns7:Root-Element/ns7:Books/ns7:BOOK_NO".


basically I had to specify an index in the XPath to return only 1 element....

If you don't provide a fault handler, the actual cause is not logged in the logs...
