Web pages use JavaScript to make asynchronous calls to web-based services that typically return XML allows user to continue interacting with web page while waiting for data to be returned page can be updated without refreshing browser results in a better user experience there are AJaX libraries that reduce the amount of JavaScript code that must be written Uses a JavaScript class called XMLHttpRequest

 It provide the ability to see a tree view of the directory structure of the server the application is running on. Provides facility to perform basic operations of copying files and directories, moving files and directories Provides the ability to edit the files. Uploading and downloading files. When select a directory from the tree, it shows the contents of that directory in a grid, showing us the item’s name, size, type, and last modified date/time. Implement security check using container-managed J2EE security UI look similar to Windows Explorer.
