/**
 * {@code Databinding} is the entry point for all the WebService Databinding
 * functionality. Primarily, a Databinding is to serialize/deserialize an
 * XML(SOAP) message to/from a JAVA method invocation and return which are
 * represented as JavaCallInfo instances. A WSDLGenerator can
 * be created from a Databinding object to genreate WSDL representation of 
 * a JAVA service endpoint interface.
 * 

*

* The supported databinding modes(flavors) are: *
    *
  • "toplink.jaxb"
  • *
  • "glassfish.jaxb"
  • *
*
Following is an example that creates a {@code Databinding} which * provides the operations to serialize/deserialize a JavaCallInfo to/from a * SOAP message:
* *
 * DatabindingFactory factory = DatabindingFactory.newInstance();
 * Databinding.Builder builder = factory.createBuilder(seiClass, endpointClass);
 * Databinding databinding = builder.build(); 
 *
