Colm O hEigeartaigh commented on CXF-7787:
------------------------------------------
I'll fix the NPE. It is actually caused by the empty "import" statement in the
first schema. However, your schemas are malformed - if you remove the empty
import statement you get the following error:
WSDLToJava Error: Schema Error : src-resolve.4.1: Error resolving component
'GetLabs_Request'. It was detected that 'GetLabs_Request' has no namespace, but
components with no target namespace are not referenceable from schema document
'file:/home/coheig/dist/apache/apache-cxf-3.2.5/LabResultsService.singleWsdl#types1'.
If 'GetLabs_Request' is intended to have a namespace, perhaps a prefix needs
to be provided. If it is intended that 'GetLabs_Request' has no namespace, then
an 'import' without a "namespace" attribute should be added to
'file:/home/coheig/dist/apache/apache-cxf-3.2.5/LabResultsService.singleWsdl#types1'.
