Hi all,
I used scomp to generate a parser for an XML file which root element
is expected to be "WorkflowManagerInstanceDescriptor". The input file
for scomp is the attached "WorkflowManager.xsd" file.
I created an XML file (UnsecureWorkflow1.xml) and validated it
against the schema using both Eclipse and Oxygen. For that reason, I
believe the XML file is valid.
However, when parsing it using the generated XMLBeans parser, I can't
retrieve the information. Executing the attached java class gives an
error message that claims the XML file isn't valid. So, have scomp not
generated the parser appropriately or is one of my files invalid?
