How to consume SharePoint Service Response (Java/.NET interop)?
We would like to connect a Java Web services CXF client to the SharePoint
List service. After overcoming the NTLM issue, we see that the response is
not being properly returned to the client (it returns null). We used the
Maven cxf-codegen-plugin wsdl2java to create the client stub classes that
would represent the results but we get back NULL every time.
Here's the code to make the call and return the result (this all works
except for the return value is an empty list):
public static GetListCollectionResult getListCollection(NTLMAuthenticator
auth, String endPoint) {
Lists lists = new Lists();
ListsSoap stub = lists.getListsSoap();
BindingProvider bindProvider = (BindingProvider) stub;
bindProvider.getRequestContext().put(
BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endPoint);
Authenticator.setDefault(auth);
setConduit(stub);
return stub.getListCollection();
}
Here is the sample output that repeats the List element that we can retrieve
using C#:
<Lists xmlns="http://schemas.microsoft.com/sharepoint/soap/">
<List DocTemplateUrl="" DefaultViewUrl="/Lists/Audited Root Task
List/AllItems.aspx"
MobileDefaultViewUrl="" ID="{AAAABEE6-CSDD-4C70-8AD0-567372066760}"
Title="Audited Root Task List" Description=""
ImageUrl="/_layouts/images/ittask.gif"
Name="{AAAABEE6-CSDD-4C70-8AD0-567372066760}"
BaseType="0" FeatureId="00bfea71-a83e-497e-9ba0-7a5c597d0107"
ServerTemplate="107" Created="20090805 06:31:27" Modified="20090818
06:09:13"
LastDeleted="20090805 07:23:22" Version="35" Direction="none"
ThumbnailSize="" WebImageWidth="" WebImageHeight="" Flags="549457920"
ItemCount="5" AnonymousPermMask="0" RootFolder="" ReadSecurity="1"
WriteSecurity="1" Author="55" EventSinkAssembly="" EventSinkClass=""
EventSinkData="" EmailInsertsFolder="" EmailAlias="" WebFullUrl="/"
WebId="2bdcc5a2-563f-477c-b6d9-cf26c0067b36" SendToLocation=""
ScopeId="ca78103c-95d7-4ffd-8cf1-77eb3b9a37ae" MajorVersionLimit="0"
MajorWithMinorVersionsLimit="0" WorkFlowId="" HasUniqueScopes="False"
AllowDeletion="True" AllowMultiResponses="False" EnableAttachments="True"
EnableModeration="False" EnableVersioning="False" Hidden="False"
MultipleDataList="False" Ordered="False" ShowUser="True"
EnableMinorVersion="False" RequireCheckout="False" />
...
Here is the generated wsdl2java class for JAXB binding of the response:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
"getListCollectionResult"
})
@XmlRootElement(name = "GetListCollectionResponse")
public class GetListCollectionResponse {
@XmlElement(name = "GetListCollectionResult")
protected GetListCollectionResponse.GetListCollectionResult
getListCollectionResult;
public GetListCollectionResponse.GetListCollectionResult
getGetListCollectionResult() {
return getListCollectionResult;
}
public void
setGetListCollectionResult(GetListCollectionResponse.GetListCollectionResult
value) {
this.getListCollectionResult = value;
}
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
"content"
})
public static class GetListCollectionResult {
@XmlMixed
@XmlAnyElement(lax = true)
protected List content;
public List getContent() {
if (content == null) {
content = new ArrayList();
}
return this.content;
}
}
}
Any ideas on how to bind the CAML formatted output from the SP Web service
so the response can be unmarshalled properly by JAXB?
TIA!
Lou

Yes, you need to add additional code to parse the XML yourself.
This interceptor just allows you to capture the XML, it won't fix/change the
returned List value.
But now that you have the XML you can extract what you need to process it.

I tried this interceptor below. I added some printlns and saw that the
originalXML string was being set correctly. However, that string is not
used anywhere so I'm not sure if this is missing some code or not. The end
result is that even though I can see that the correct data is available in
the handleMessage, using that code below, it doesn't work still. I still
get the null List object back. Is there additional code beyond this that is
needed to make it work?

Oh yes, forgot to mention, another way would be with JAXB is to add an
interceptor and process the stream before the StaxInInterceptor does.
eg:
<code>
static class MyInterceptor extends AbstractPhaseInterceptor<Message> {
public MyInterceptor() {
super(Phase.POST_STREAM);
getBefore().add(StaxInInterceptor.class.getName());
}
public void handleMessage(Message msg) throws
org.apache.cxf.interceptor.Fault {
InputStream is = msg.getContent(InputStream.class);
assert is != null;
try {
byte[] byteContent = IOUtils.readBytesFromStream(is);
msg.setContent(InputStream.class, new
ByteArrayInputStream(byteContent));
String encoding = (String) msg.get(Message.ENCODING);
String originalXML = new String(byteContent,encoding);
} catch(Exception e) {
//FIXME: handle exception
e.printStackTrace();
}
}
}
</code>

Probably this is late now, but I was facing the same issue. (Sharepoint,
NTLMv2, List[null])
Using JAXB GetList always returned null, but switching to XMLBEANS I do get
the xml content of the getList response.
Hope this helps someone.

Hello,
Do you have a solution for this yet? I am facing a similar issue. The CXF is
returning null.
Please share if you have the solution.
Thanks

USUALLY, this kind of error is a result of the message not actually matching
the schema in the wsdl. Normally, that is due to the schema not saying
elementFormDefault="qualified" and then sending a message like you have below
that qualifies everything. I would double check the wsdl that was used to
generate the code.
If using CXF 2.2.3, you can try add -xjc-npa to the wsdl2java flags that
would cause more information to be output in the annoations. You should
expect to see namespace attributes on almost everything.
