+ * Use to send messages to ESB services from jBPM applications.
+ * <p/>Assumptions:
+ * <br/> Message payload is in the context instance in a context variable.
+ * <br/>Context variables "esbCategoryName" and "esbServiceName" will be supplied at runtime.
+ * 
+ * <p/> The name of the context variable that contains the user object to include in the
+ * message payload is rendered by the getContentVariableName() method
+ * so it can be changed just by extending this class and overriding that method.
+ * 
+ * <br/> This action handler will by default (whenever possible) include the process name
+ * , version, processInstance id and token ID
+ *
