A web content management system is used to control a dynamic collection of web material, including [url="http://en.wikipedia.org/wiki/HTML"]HTML[/url]documents, [url="http://en.wikipedia.org/wiki/Image"]images[/url], and other forms of media.[sup][url="http://en.wikipedia.org/wiki/Web_content_management_system#cite_note-3"][3][/url][/sup] A CMS facilitates document control, auditing, editing, and timeline management. A WCMS typically has the following features:[sup][url="http://en.wikipedia.org/wiki/Web_content_management_system#cite_note-4"][4][/url][/sup][sup][url="http://en.wikipedia.org/wiki/Web_content_management_system#cite_note-5"][5][/url][/sup][/size][/font][/color] Automated templates Create standard output templates (usually HTML and [url="http://en.wikipedia.org/wiki/XML"]XML[/url]) that can be automatically applied to new and existing content, allowing the appearance of all content to be changed from one central place. Access control Some WCMS systems support user groups. User groups allow you to control how registered users interact with the site. A page on the site can be restricted to one or more groups. This means an anonymous user (someone not logged on), or a logged on user who is not a member of the group a page is restricted to, will be denied access to the page. Scalable expansion Available in [url="http://en.wikipedia.org/wiki/List_of_content_management_systems"]most modern WCMSs[/url] is the ability to expand a single implementation (one installation on one server) across multiple domains, depending on the server's settings. WCMS sites may be able to create [url="http://en.wikipedia.org/wiki/Microsite"]microsites[/url]/[url="http://en.wikipedia.org/wiki/Web_portal"]web portals[/url] within a main site as well. Easily editable content Once content is separated from the visual presentation of a site, it usually becomes much easier and quicker to edit and manipulate. Most WCMS software includes [url="http://en.wikipedia.org/wiki/WYSIWYG"]WYSIWYG[/url] editing tools allowing non-technical users to create and edit content. Scalable feature sets Most WCMS software includes plug-ins or modules that can be easily installed to extend an existing site's functionality. Web standards upgrades Active WCMS software usually receives regular updates that include new feature sets and keep the system up to current web standards. Workflow management [url="http://en.wikipedia.org/wiki/Workflow"]workflow[/url] is the process of creating cycles of sequential and parallel tasks that must be accomplished in the CMS. For example, one or many content creators can submit a story, but it is not published until the copy editor cleans it up and the editor-in-chief approves it. Collaboration CMS software may act as a [url="http://en.wikipedia.org/wiki/Collaboration_platform"]collaboration platform[/url] allowing content to be retrieved and worked on by one or many authorized users. Changes can be tracked and authorized for publication or ignored reverting to old versions. Other advanced forms of collaboration allow multiple users to modify (or comment) a page at the same time in a collaboration session. Delegation Some CMS software allows for various user groups to have limited privileges over specific content on the website, spreading out the responsibility of content management.[sup][url="http://en.wikipedia.org/wiki/Web_content_management_system#cite_note-6"][6][/url][/sup] Document management CMS software may provide a means of collaboratively managing the life cycle of a document from initial creation time, through revisions, publication, archive, and document destruction. Content virtualization CMS software may provide a means of allowing each user to work within a virtual copy of the entire web site, document set, and/or code base. This enables changes to multiple interdependent resources to be viewed and/or executed in-context prior to submission. Content syndication CMS software often assists in content distribution by generating [url="http://en.wikipedia.org/wiki/RSS"]RSS[/url] and [url="http://en.wikipedia.org/wiki/Atom_(standard)"]Atom[/url] data feeds to other systems. They may also e-mail users when updates are available as part of the workflow process. Multilingual Ability to display content in multiple languages. Versioning Like [url="http://en.wikipedia.org/wiki/Document_management_system"]document management systems[/url], CMS software may allow the process of [url="http://en.wikipedia.org/wiki/Versioning"]versioning[/url] by which pages are checked in or out of the WCMS, allowing authorized editors to retrieve previous versions and to continue work from a selected point. Versioning is useful for content that changes over time and requires updating, but it may be necessary to go back to or reference a previous copy.

like ..most web sites which r news related are using XSLT a lot ..(just by view source my guess)

like Amzon and other Services providers will is WCWS

[/quote][color=#262626][background=rgb(251, 251, 251)]The word ‘polymorphism’ literally means ‘[b]a state of having many shapes[/b]’ or ‘the [b]capacity to take on different forms[/b]’[/background][/color]
[color=#262626][background=rgb(251, 251, 251)]Polymorphism in Java has two types: [b]Compile time polymorphism (static binding) and Runtime polymorphism (dynamic binding[/b]). [b]Method overloading is an example of static polymorphism[/b], while[b] method overriding is an example of dynamic polymorphism.[/b][/background][/color]


[b] Static Polymorphism:[/b]

In Java, static polymorphism is achieved through method overloading. Method overloading means there are several methods present in a class having the same name but different types/order/number of parameters.
At compile time, Java knows which method to invoke by checking the method signatures. So, this is called [b]compile time polymorphism[/b] or [b]static binding[/b]. The concept will be clear from the following example:
class DemoOverload{

public int add(int x, int y){ //method 1

return x+y;

}

public int add(int x, int y, int z){ //method 2

return x+y+z;

}

public int add(double x, int y){ //method 3

return (int)x+y;

}

public int add(int x, double y){ //method 4

return x+(int)y;

}

}

class Test{

public static void main(String[] args){

DemoOverload demo=new DemoOverload();

System.out.println(demo.add(2,3)); //method 1 called

System.out.println(demo.add(2,3,4)); //method 2 called

System.out.println(demo.add(2,3.4)); //method 4 called

System.out.println(demo.add(2.5,3)); //method 3 called

}

}
In the above example, there are four versions of add methods. The first method takes two parameters while the second one takes three. For the third and fourth methods there is a change of order of parameters. The compiler looks at the method signature and decides which method to invoke for a particular method call at compile time.

explain dynamic polymorphism please!!!
[/quote][color=#262626][background=rgb(251, 251, 251)]Suppose a sub class overrides a particular method of the super class. Let’s say, in the program we create an object of the subclass and assign it to the super class reference. Now, if we call the overridden method on the super class reference then the sub class version of the method will be called.[/background][/color]
Have a look at the following example.
class Vehicle{

public void move(){

System.out.println(“Vehicles can move!!”);

}

}

class MotorBike extends Vehicle{

public void move(){

System.out.println(“MotorBike can move and accelerate too!!”);

}

}

class Test{

public static void main(String[] args){

Vehicle vh=new MotorBike();

vh.move(); // prints MotorBike can move and accelerate too!!

vh=new Vehicle();

vh.move(); // prints Vehicles can move!!

}

}
It should be noted that in the first call to move(), the reference type is Vehicleand the object being referenced is MotorBike. So, when a call to move() is made, Java waits until runtime to determine which object is actually being pointed to by the reference. In this case, the object is of the class MotorBike. So, the move() method of MotorBike class will be called. In the second call tomove(), the object is of the class Vehicle. So, the move() method of Vehiclewill be called.
As the method to call is determined at runtime, this is called [b]dynamic binding[/b] or[b]late binding[/b].
