the following code , which shows hot use the progressbar in the java swing... it uses the swing worker to animate its progress while installing or doing some updations....

refer this link for further doubts...
swingworker:http://java.sun.com/docs/books/tutorial/uiswing/concurrency/simple.html

/**
this class progress is used to create to update the value by swing worker to the process method.
this class type is mentioned in the swing worker it has two type of parameter, first shows the done method, and it should be overridden. the second parameter specifies the this call, and u should override the process method..

Struts Tutorial Page

           Difference between Model 1 and Model 2 architecture: Features of MVC1: Html or jsp files are used to code the presentation. To retrieve the data JavaBean can be used. In mvc1 archictecture all the view, control elements are implemented using Servlets or Jsp. In MVC1 there is tight coupling between page and model as data access is usually done using Custom tag or through java bean call. Features of MVC2: The MVC2  architecture removes the page centric property of MVC1 architecture by separating Presentation, control logic and the application state. In MVC2 architecture there is only one controller which receives all the request for the application and is responsible for taking appropriate action in response to each request. Struts framework provides three key components: A  request  handler provided by the application developer that is used to  mapped to a particular URI. A  response  handler which is used to...
