How do I instantiate a JAXBElement<String> object?
When you imported the WSDL, you should have an ObjectFactory
class which should have bunch of methods for creating various input parameters.
ObjectFactory factory = new ObjectFactory();
JAXBElement<String> createMessageDescription = factory.createMessageDescription("description");
message.setDescription(createMessageDescription);
ObjectFactory fact = new ObjectFactory();
JAXBElement<String> str = fact.createCompositeTypeStringValue("vik");
comp.setStringValue(str);
CompositeType retcomp = service.getDataUsingDataContract(comp);
System.out.println(retcomp.getStringValue().getValue());
Here is how I do it. You will need to get the namespace URL and the element name from your generated code.
new JAXBElement(new QName("http://www.novell.com/role/service","userDN"),
new String("").getClass(),testDN);
