"javax.xml.ws.WebServiceException: java.lang.NullPointerException" in JBoss WS

Issue

• This application which throws this error is a client to a web service. The error is:

javax.xml.ws.WebServiceException: java.lang.NullPointerException
                at org.jboss.ws.core.jaxws.spi.ProviderImpl.createServiceDelegate(ProviderImpl.java:72)
                at javax.xml.ws.Service.<init>(Service.java:56)
                at com.example.xxxxx.XxxxxService.<init>(XxxxxService.java:33)

• On analysis we found that there is JBPAPP-6389 that is fixed from EAP 5.1.2 - that could be the source of this issue - since the WSDL in question has the following structure:

<xs:schema targetNamespace="http://response.jaxws.xxxxx.example.com/" version="1.0" xmlns:ns1="http://header.jaxws.xxxxx.example.com/" xmlns:ns2="http://model.xxxxx.example.com/" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:import namespace="http://header.jaxws.xxxxx.example.com/" /> 
  <xs:import namespace="http://model.xxxxx.example.com/" />

• Is this the source of the problem? if yes, how to fix this?
• We applied most of the patches for EAP 5.1.2 that are available in Red Hat Customer Portal.
