The error message suggests to me that there is no class ObjectFactory, or not where it ought to be, for JAXB to be happy. If you JAXB-annotate your Java classes by hand, you'll also have to write an ObjectFactory.java.

A little info can be found in my JAXB tutorial. Also, you could apply xjc to an XML Schema to learn how it's done ;-)

Update:


So I have the following as code that I found in a blog by salaboy...

List<String> myDomainClasses = new ArrayList<String>();
myDomainClasses.add("com.test.TestFact");


// I need to create a JAXB context including my domain classes
// to be able to create a JAXB representation to send to the server

JAXBContext jaxbContext =
DroolsJaxbContextHelper.createDroolsJaxbContext(myDomainClasses, null);

TestFact test = new TestFact();



// Once I get my object I need to create
// some commands to execute on the server
// Here I include a reference to the session that
// I define in my Knowledge Context Profile

List<Command> listOCommand = new ArrayList<Command>();
listOCommand.add(new InsertObjectCommand(test, "testFact"));

BatchExecutionCommand cmd = CommandFactory.newBatchExecution(listOCommand,
"ksession1");

// Once I get all I need to send to the server,
// I need to use the JAXB context
// to obtain the JAXB representation.

StringWriter xmlReq = new StringWriter();
javax.xml.bind.Marshaller marshaller = jaxbContext.createMarshaller();
marshaller.setProperty("jaxb.formatted.output", true);
marshaller.marshal(cmd, xmlReq);

// I create a HTTPClient to interact with the
// server via REST (HTTP POST)

DefaultHttpClient httpClient = new DefaultHttpClient();

HttpParams params = new BasicHttpParams();
params.setParameter(ClientPNames.DEFAULT_HOST, "localhost");

//Print the JAXB xml that we will send to the server
System.out.println(xmlReq.toString());

// Send the Commands JAXB representation to the server for execution
HttpPost postMethod = new
HttpPost("http://localhost:8080/MyService/kservice/rest/execute");

HttpParams p = new BasicHttpParams();
p.setParameter("command",  xmlReq.toString());
postMethod.setParams(p);

HttpResponse response = httpClient.execute(postMethod);

System.out.println(response);


Now I had to change a few things from the blog but it should be basically
the same as the post... I get the following exception...

1872701 [http-8080-1] ERROR processor.DefaultErrorHandler  - Failed delivery

Thanks for any advice on this matter...
