Array/Collection parameter for web service is coming in null
Hi,
I am using cxf 2.0.9 and JAX WS to write a web service. I have never written
one that takes parameters besides the primitive types and my thought is I am
missing a step. I have coded the web service and written a test in java that
is successful however when clients outside of java are attempting to consume
the service its not working. In an attempt to test this situation I use
soapUI and try to make a valid soap call to the service and the array is
still coming in null. I tried re writing the service to take a
collection(instead of the array) and I still see the same issue.
The method signature looks like this:
@WebMethod(operationName="getMix")
@WebResult(name="result")
Mix getMix(
@WebParam(name = "length")String length,
@WebParam(name = "bitrate")String bitrate,
@WebParam(name = "audio") Collection<Audio> audio
);
It returns a object of type mix and in the WSDL I see these lines which make
me think the web service understands the mix object
<xs:complexType name="mix">
-
<xs:complexContent>
-
<xs:extension base="abstractEntity">
-
<xs:sequence>
<xs:element minOccurs="0" name="status" type="xs:string"/>
<xs:element minOccurs="0" name="url" type="xs:string"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
There isn't as any information in the WSDL for the type Audio which I am
thinking this is why I am having an issue. Here is what I see for the method
above in the WSDL:
<xs:element name="getMix" type="getMix"/>
-
<xs:complexType name="getMix">
-
<xs:sequence>
<xs:element minOccurs="0" name="length" type="xs:string"/>
<xs:element minOccurs="0" name="bitrate" type="xs:string"/>
<xs:element maxOccurs="unbounded" minOccurs="0" name="audio"/>
</xs:sequence>
</xs:complexType>
<xs:element name="getMixResponse" type="getMixResponse"/>
-
<xs:complexType name="getMixResponse">
-
<xs:sequence>
<xs:element minOccurs="0" name="result" type="mix"/>
</xs:sequence>
</xs:complexType>
Do I need to do something to the Audio class to have the web service better
understand how to represent this collection (or array)?
Thanks,
Barry

Thanks Dan, that worked. The Audio class had no default constructor by
accident. Once in place the WSDL generated more information about the Audio
object and I was able to test the service from java and soapUI without an
issue.

What does the Audio class look like?
Does it have a default constructor? Are all properties defined with public
getter and setters?
That all said, I wold definitely encourage you to upgrade to a newer version
of CXF.
