/**
 * {@link com.sun.xml.ws.client.sei.MethodHandler} that handles synchronous method invocations.
 *
 * 

* This class mainly performs the following two tasks: *

    *
  1. Accepts Object[] that represents arguments for a Java method, * and creates {@link com.sun.xml.ws.message.jaxb.JAXBMessage} that represents a request message. *
  2. Takes a {@link com.sun.xml.ws.api.message.Message] that represents a response, * and extracts the return value (and updates {@link javax.xml.ws.Holder }s.) *
* *
