NullPointerException with overloaded methods in Beta 2
Hi, we have the following five overloaded method signatures in a published
SOAP object in Axis Beta 2 (don't ask why we have so many, that's out of my
control at the moment):
public List getProfiles(String profileType, Map matchCriteria);
public List getProfiles(String containedType, String containerType,
Map containerCriteria);
public List getProfiles(String profileType, Map criteria,
List orderByKeys, int windowSize, int
position);
public List getProfiles(String containedType, String containerType, Map
containerCriteria,
List orderByKeys, int windowSize, int position);
public List getProfiles(String containedType, String containerType, Map
containerCriteria,
List orderByKeys, Map requestParameters, int
windowSize, int position);
They all work fine except for the methods with two and three parameters,
which generate the NPE stack trace below. Perhaps this is related to open
Bug 7722, as our SOAP interface extends another interface, however, the wsdl
(relevant bits below) shows all the methods with the correct parameters.
Any help appreciated. Also, all our protected methods seem to be being
exposed in the WSDL as well, but I think a few people have already mentioned
that one.
Thanks,
Martin
WSDL snippet:
- <wsdl:operation name="getProfiles" parameterOrder="containedType
containerType containerCriteria orderByKeys windowSize position">
<wsdl:input message="intf:getProfilesRequest" />
<wsdl:output message="intf:getProfilesResponse" />
</wsdl:operation>
- <wsdl:operation name="getProfiles" parameterOrder="containedType
containerType containerCriteria orderByKeys requestParameters windowSize
position">
<wsdl:input message="intf:getProfilesRequest1" />
<wsdl:output message="intf:getProfilesResponse1" />
</wsdl:operation>
- <wsdl:operation name="getProfiles" parameterOrder="profileType criteria
orderByKeys windowSize position">
<wsdl:input message="intf:getProfilesRequest2" />
<wsdl:output message="intf:getProfilesResponse2" />
</wsdl:operation>
- <wsdl:operation name="getProfiles" parameterOrder="profileType
matchCriteria">
<wsdl:input message="intf:getProfilesRequest3" />
<wsdl:output message="intf:getProfilesResponse3" />
</wsdl:operation>
- <wsdl:operation name="getProfiles" parameterOrder="containedType
containerType containerCriteria">
<wsdl:input message="intf:getProfilesRequest4" />
<wsdl:output message="intf:getProfilesResponse4" />
</wsdl:operation>

Overloaded methods is a known bug in beta2. Get current versions from
CVS.
