Key: AXIS2-4822
URL: https://issues.apache.org/jira/browse/AXIS2-4822
Project: Axis2
Issue Type: Bug
Components: jaxws
Affects Versions: 1.5.1
Environment: websphere 6.1.23 unix
Reporter: Maryna Zilske
'equals ' and 'hashCode ' method is missing in
org.apache.axis2.jaxws.description.impl.FaultDescriptionImpl.class
The class org.apache.axis2.jaxws.description.impl.
OperationDescriptionImpl.class has an attribute 'faultDescriptions'. This
attribute is an ArrayList of
org.apache.axis2.jaxws.description.impl.FaultDescriptionImpl- objects.
The class
org.apache.axis2.jaxws.runtime.description.marshal.impl.MarshalServiceRuntimeDescriptionImpl
has an attribute 'faultBeanDescMap'. This attribute is a HashMap contended:
key value a org.apache.axis2.jaxws.description.impl.FaultDescriptionImpl
value object an instance of
org.apache.axis2.jaxws.runtime.description.marshal.impl.FaultBeanDescImpl.class
We have a productive runtime NullPointerEception in
org.apache.axis2.jaxws.marshaller.impl.alt MethodMarshallerUtils in the method
demarshalFaultResponse on line
QName tryName = new (faultBeansDesc.getFaultBeanNameSpase ...
because faultBeansDesc is null:

The out- and in- messages are correct. If no
RuntimeDescriptions:1
MarshalServiceRuntime:JAXWS-MARSHAL
....
in log file is available, the program runs correct. So the failure is only on
runtime description fragment.
Actually code in MethodMarshallerUtils musts fail, because:
FaultDescription fd = operationDesc.getFaultDescriptions()[i];
// gives an instance of FaultDescriptionImpl from ArrayList
FaultBeanDesc faultBeanDesc = marshalDesc.getFaultBeanDesc(fd);
// search for instance in another HashMap and a key value for search hasn't
equals method,
// the next code trays to operate with NULL object:
QName tryQName = new QName(faultBeanDesc.getFaultBeanNamespace(), ...
Please, consider to correct this bug.
Our solution for production environment is to redefine the interface. There are
only request and response messages and no fault any more. It is not pretty.
