Client code does not parse AxisFault correctly.
-----------------------------------------------
Key: AXIS2-1846
URL: http://issues.apache.org/jira/browse/AXIS2-1846
Project: Apache Axis 2.0 (Axis2)
Issue Type: Bug
Components: client-api, codegen
Affects Versions: 1.1
Environment: Linux.
Reporter: Sathija Pavuluri
I am investigating the exception handling capability of Axis and created a
sample web service.
My axis web service is throwing an exception wrapped inside an AxisFault. The
service uses rampart for security.
This is what is in the service class method:
if (devices == null) {
throw new AxisFault(new NullPointerException("No devices have been
rerieved"));
}
and the method throws AxisFault.
When i invoke this call and no exception is returned, the result is obtained
without a problem.
However, when I invoke the axis client which calls this service with parameters
in a way that I expect to get the NullPointerException above, I get the output
stack shown below.

Given below is the soap response as seen in the tcp monitor. This response
looks as expected. I see the NullPointerException and the associated message.

Something seems wrong with the way the client api is parsing the fault from the
soap body. And why do I see the RampartException anyway?
I've caught the AxisFault that is being thrown and it has no properties or the
NullPointerException, all is has is this:
org.apache.axis2.AxisFault: Error in extracting message properties; nested
exception is:
org.apache.rampart.RampartException: Error in extracting message
properties
I had posted the same on the user list and was asked to file a JIRA.
Thanks,
Sathija.
