Description

with the exception class below , it only has a get*** method for the
info property.

@WebFault
public TestException extends Exception {
private String message = null;

public TestException () {
}

public TestException (String message)

{ this.message = message; }

public String getInfo()

{ return message; }

}

With the RI wsgen command, the generated schema type is :
RI:
<xs:complexType name="TestException">
<xs:sequence>
<xs:element name="info" type="xs:string" minOccurs="0"/>
<xs:element name="message" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
</xs:schema>

If using CXF tool or on the CXF runtime, the generated schema type for the
exception is :

<xs:element name="TestException" type="tns:TestException"/>
<xs:complexType name="TestException">
<xs:sequence/>
</xs:complexType>

With the JaxWS spec, 3.7 Service Specific Exception, considering that no
getFaultInfo or faultBean in WebFault annotation is provided, the
special algorithm will be used to map the exception to jaxb bean, one of
the steps write below:

For each getter in the exception and its superclasses, a property of the
same type and name is added to
the bean. All the getter methods except
getMessagefromjava.lang.Throwabletype hierarchy
are excluded from the list of getters to be mapped.

Seems that only getter method is required, with the current codes in static
boolean JAXBContextInitializer.isMethodAccepted, it will check whether the
setter exists. I am thinking that this is not required for this scenario,
as we only need to read the information from the user exception.

The patch will return true is the getter method has no corresponding setter method to let CXF comply with the jax-ws 2.2 spec:
For each getter in the exception and its superclasses, a property of the
same type and name is added to
the bean. All the getter methods except
getMessagefromjava.lang.Throwabletype hierarchy
are excluded from the list of getters to be mapped.
