Jaxb: How to create an ObjectFactory class?

Question

I use Java 6, JaxB 2, and SpringSource Tool Suite (same as Eclipse). I had several Java classes that I wrote, of which I used JaxB to create the XML schema. However, I notice that to use the JaxB feature to create an XML document from Java objects, I need an ObjectFactory.

final Marshaller marshaller = jaxbContext.createMarshaller();
// Here is where I don't have an ObjectFactory defined
final JAXBElement<WebLeads> webLeadsElement  
         = (new ObjectFactory()).createWebLeads(webLeadsJavaObj);

How can I generate an ObjectFactory without dropping the classes that I already have?

Thanks - Dave
