+/**
+ * <p>
+ * The servant is responsible for handling the method invocation on the
+ * target object. It can be one servant per object, or the same servant can
+ * support several (possibly all) objects, associated with the given POA.
+ * </p> <p>
+ * Till JDK 1.3 inclusive, a typical IDL to java compiler generates an
+ * implementation base (name pattern _*ImplBase.java) that is derived from the
+ * {@link org.omg.CORBA.portable.ObjectImpl}. Since JDK 1.4 the implementation
+ * base is derived from the Servant, also having a different name pattern
+ * (*POA.java). This suffix may be confusing, as the servant itself is
+ * <i>not</i> POA nor it is derived from it.
+ * </p><p>
+ * In both cases, the implementation base also inherits an interface, containing
+ * definitions of the application specific methods. The application programmer
+ * writes a child of the implementation base, implementing these methods
+ * for the application-specific functionality. The ObjectImpl is connected
+ * directly to the ORB. The Servant is connected to POA that can be obtained
+ * from the ORB.
+ * </p><p>
+ * If the servant is connected to more than one object, the exact object
+ * being currently served can be identified with {@link #_object_id}.
+ * </p><p>
+ * The derivativ of Servant, being directly connected to serve requests,
+ * must inherit either from {@link org.omg.CORBA.portable.InvokeHandler}
+ * or from {@link org.omg.PortableServer.DynamicImplementation}).
+ * </p><p>
+ * The Servant type is a CORBA <code>native</code> type.
+ * </p>
