---------------------------------------
Summary: useOriginalwsdl + service exceptions =
NullPointerException
Key: AXIS2-5506
URL: https://issues.apache.org/jira/browse/AXIS2-5506
Project: Axis2
Issue Type: Bug
Affects Versions: 1.6.2, 1.6.1
Environment: Windows XP, IBM WebSphere 7, Java 1.6.0_24-b07
Reporter: Wouter Amerijckx
In both Axis2 1.6.1 and 1.6.2, an issue occurs when using an "original" WSDL
file for a service that throws exceptions in its service methods.
The issue occurs with:
- Spring integration with Spring 2.0.8
- The service packaged in an AAR
> services.xml's useOriginalwsdl=true
> META-INF/serviceName.WSDL in place
Initially, I deployed the AAR without useOriginalwsdl and without a custom WSDL
file. Axis2 generated the WSDL,
I downloaded it through my web browser and put it in META-INF/serviceName.WSDL.
For now, I left the file unmodified but am planning to modify it later (i.e.,
its minOccurs values).
The issue occurs when a service method completes but throws an exception.
Without the "original WSDL", Axis2
serializes this exception perfectly to XML. With the original WSDL in place,
the following happens:
Version 1.6.1:

I made an attempt to debug the code, and it seems that
inMessage.getAxisService().getTypeTable() is null, which is not the case
when not using an "original WSDL".
