Ich bin neu in BPEL und kämpfe um loszulegen.Apache ODE BPEL soapenv: Server axis2ns1: selectionFailure
habe ich eine einfache If/Else-Workflow, aber die folgende Fehlermeldung erhalten, wenn ich die WSDL-Datei mit Eclipse Web-Services-Explorer mich entschieden:
soapenv:Server axis2ns1:selectionFailure
Mein Verständnis von anderen ähnlichen Fragen ist es wahrscheinlich etwas sehr einfach und im Zusammenhang mit dem Namespace oder Variablennamen in der if-Bedingung, aber ich kann nicht verstehen warum und wie man es löst.
Ich verwende Apache ODE 1.3.7 auf Eclipse 4.7.1 Oxygen und Tomcat 8.5.
Das ist mein Workflow-Design:
