A JMS object message class is very simple: it is a serializable JavaBean that carries the message properties. Our LinkMessage class will have only one property: location.

package test.scenario;

/**
           * JMS message that conveys data about a link clickthrough event.
           *
           **/
          public class LinkMessage implements java.io.Serializable
          {
            //----------------------------------------
            // CONSTRUCTORS
            //----------------------------------------
            public LinkMessage(String pLocation)
            {
              setLocation(pLocation);
            }
            //----------------------------------------
            // PROPERTY ACCESSORS
            //----------------------------------------
            String mLocation;
            //-------------------------------------
            /**
             * Sets the logical name of the clickthrough location.
             **/
            public void setLocation(String pLocation) {
              mLocation = pLocation;
            }
            //-------------------------------------
            /**
             * Returns the logical name of the clickthrough location.
             **/
            public String getLocation() {
              return mLocation;
            }
          }
