GenericServlet is for servlets that might not use HTTP, like for instance FTP servlets. Of course, it turns out that there's no such thing as FTP servlets, but they were trying to plan for future growth when they designed the spec. Maybe some day there will be another subclass, but for now always use HttpServlet.

Serializable interface is an empty interface present in java.io package. It is implemented by classes that are to be serialized. Serialization is the process of converting an object into a stream of bytes. object must be serializable if it is to be written to disk or transfered in distributed applications. The following example shows class Student implementing this interface to indicate to Java that its object can be serialized by Java. public class Student implements java.io. See similar questions...

import java.io.*; public class CustomDataExample implements Serializable { transient int dimension; transient int thearray[][]; /** ... See similar questions...

No. This is a common misconception. The deserialization process does not use the object's constructor - the object is instantiated without a constructor and... The SUID is one of a number of things that the serialization protocol writes to the stream in addition to the serialized object (other things include... Is there any way to save the state of an object of a class which does not implement Serializable or Extenalizable?. Yes. See similar questions...

It must provide all of the methods in the interface and identify the interface in its implements clause. See similar questions...

IDropTarget is a new interface that factors out the four drag drop methods - OnDragEnter, OnDragLeave, OnDragDrop, and OnDragOver - into an interface so that it can be implemented elsewhere. It is mostly an implementation detail. See similar questions...

No, a type must not directly or indirectly derive from two different instantiations of the same generic interface. The reason for this restriction is the translation by type erasure. After type erasure the different instantiations of the same generic interface collapse to the same raw type. At runtime there is no distinction between the different instantiations any longer.

The DataModel class (used with UIData components) doesn't have any state that needs to be preserved between render and restore-view phases. Therefore, there is no need for it to be serializable. If you have a managed bean that you want to be serializable, and there is a member of type DataModel then just mark it transient. See similar questions...

The component orientation property is respected only by Swing components and layout managers, not by peered AWT components. It is independent of the host operating system. The following classes support component orientation in Java SE 6, J2SE 5.0 and J2SE 1.4.2: In J2SE 1.3.1, the following classes shown in the table above do not support component orientation: java.awt.GridBagLayout, javax.swing.BoxLayout, javax.swing.JColorChooser javax.swing.JComboBox, javax.swing.JFileChooser, javax.swing.

The Integrated Student Information System (ISIS) will not be replaced until Phase 3 of the project. There will be several interfaces between ISIS and the Integrated System to transact business in the areas of financial aid and collection and recording of tuition and fees. Other systems (e.g., Maximo) may never be replaced by the Integrated System if they offer unique features required by the specific business operation. See similar questions...

Monitoring of some environmental indicators take places regularly (for air quality, waste, water and so on). Yes. Training sessions have been organized by the ISO14001 Steering Group in November 1999, August 2000, December 2000 and November 2001. Records can be found on the UNU ISO14001 Online Forum. The training materials are also available on the UNU ISO14001 Online Forum. See similar questions...

This issue is a little more complex than it first appears. There are really two categories of class that require deterministic destruction - the first category manipulate unmanaged types directly, whereas the second category manipulate managed types that require deterministic destruction. An example of the first category is a class with an IntPtr member representing an OS file handle. An example of the second category is a class with a System.IO.FileStream member.

You will not need to open up the computer case. There are two types of the controller box: USB and ProE (com port). The USB controller is used for Win98, ME, 2000 or iMac, G3, G4. The USB controller can be plugged into the computer's USB port without turning the power off. The ProE controller is used for Win95, 98, ME, 2000, NT4.0. and Linux. It needs to be plugged into a free com port. There is no other power source needed. See similar questions...

The interfaces are similar. But the Windows 98 interface is more like a Web browser. So you can use the same navigation and viewing techniques whether you're searching your hard disk or the Internet. Most of these options can be adjusted or switched off to resemble Windows 95. Don't worry. Windows 98 setup will have an FAT16-to-FAT32 conversion process. See similar questions...
