32: * A {@link SOAPMT} implementation that forwards all requests
33: * to a static {@link SOAPMT} instance.
34: * <p>
35: * The static is used because the WSDD registered in the
36: * {@link org.cougaar.core.service.WebServicesService} specifies
37: * the SOAPMT <i>classname</i> instead of our {@link
38: * SOAPLinkProtocol} instance. We use the static to hook
39: * the two together, otherwise the SOAP engine wouldn't have
40: * a pointer back into our Cougaar LinkProtocol instance.
41: * The static is fine, since link protocols typically have
42: * a per-node receiver instance (i.e. a "NodeServant").
43: * <p>
44: * This is analagous to the webtomcat module's "HookServlet".
45: * <p>
46: * Note that we can't use a ThreadLocal, since the classname
47: * is only instantiated when a call is received, not when we
48: * register the WSDD.
