WebService client: automating the generation of all java classes

The problem:
Sometimes when we have to make a webservice client, we have the wsdl definition file and we have to choose some tecnique to generate the java client classes. But after all the code generated automatically by the framework we have an xmlStream to treat with... So finally, we have to implement the model classes of the part of the xml that we're interested in.

To automate this final step we can generate the java classes to unmarshall the xml into java classes that matches data.

In my last project I had the requirement to do this with axis (Axis2) and xmlbeans (XMLBeans). The webService was a Sharepoint service: lists.asmx.

The solution:
Create an xml ant to transform the wsdl to java: wsdl2java-SharepointList.xml. And create another xml ant to transform the xml returned by the webService: buildSharepointListItems.xml

1.-wsdl2java-SharepointList.xml:

3. And finally, the java that call the sharepoint service:

HttpTransportProperties.Authenticator auth = new HttpTransportProperties.Authenticator();
auth.setUsername(username);
auth.setPassword(password);
auth.setDomain(domain);
auth.setHost(host);
auth.setRealm(realm);

// Ensure NTLM authentication used
List authPrefs = new ArrayList(1);
authPrefs.add(AuthPolicy.NTLM);
auth.setAuthSchemes(authPrefs);

// Get stub
ListsStub stub = new ListsStub(sharepoinService  + "_vti_bin/lists.asmx");

// Set authenticator
stub._getServiceClient().getOptions().setProperty(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE, auth);
// Get request and execute

com.microsoft.schemas.sharepoint.soap.GetListItemsDocument getListItems112 =com.microsoft.schemas.sharepoint.soap.GetListItemsDocument.Factory.newInstance();
GetListItems listaInput = GetListItems.Factory.newInstance();
listaInput.setListName(laguajeList[0]);
getListItems112.setGetListItems(listaInput );

GetListItemsResponseDocument listaResultado = stub.getListItems(getListItems112);
GetListItemsResult result = listaResultado.getGetListItemsResponse().getGetListItemsResult();
String resultString = result.xmlText();
log.debug(resultString);

resultString = resultString.replaceFirst("http://schemas.microsoft.com/sharepoint/soap/", "http://XXXXX/sharepoint/listItems");      
ListitemsDocument root= ListitemsDocument.Factory.parse(resultString);
List lista = root.getListitems().getData().getRowList();
