The browser-side framework is divided into two broad categories:

• Application framework: Provides browser functionality, but is often known to include widget abstractions and other parts, and functions primarily around the desktop GUI framework.

• Infrastructure Framework: Provides basic plumbing and portable browser abstraction for developers to create content. Typical features:

* For XMLHttpRequest wrappers to encapsulate browser-server interaction. (All of the frameworks provide this functionality).

* XML operations and queries.

* Perform DOM operations based on answers from XMLHttpRequest.

* In some cases, it is integrated with other browser-side technologies such as Flash (and potential Java applets).

Server-side frameworks typically work in the following two ways (although they are categorized here based on language differences):

· Html/js Generation: The server provides complete Html/javascript code generation and browser-server coordination, with the result that only the browser-side encoding can be customized.

• Remote invocation: JavaScript calls are routed directly to server-side functions (such as Java methods) and are returned to the JavaScript callback processor, or JavaScript invokes the server to extract information, such as session details, database queries, and so on.

• Pure javascript: application framework

The URL is: http://www.bindows.net,Bindows is a software development kit (SDK), which, through strong federated dhtml,javascript,css and XML technology, can generate highly interactive Internet applications-becoming a powerful opponent of modern desktop applications. Bindows applications do not require downloads and do not need to be installed on the client side-only one browser is required (and no java,flash or ActiveX is required). Bindows has the potential to lead the platform of Object-oriented development AJAX applications.

cpaint:http://cpaint.sourceforge.net/, is a true support for PHP and Asp/vbscript Ajax implementations and JSRS (JavaScript remote scripting) implementations. Cpaint provides you with the required code to implement Ajax and JSRs in the background, while the returned data is manipulated, formatted, and displayed in JavaScript format. This allows you to create Web applications that provide near-real-time feedback to the user.

URL: http://www.themidnightcoders.com/weborb/aboutWeborb.htm, is a platform that supports the development of Ajax and Flash based fat client applications, and can put them with Java objects and XML Web services are tied together. Online Example (http://www.themidnightcoders.com/examples)

· Weborb includes a client library called a Rich Customer System (http://www.themidnightcoders.com/rcs/index.htm). The rich customer System provides a simple online API to bind to and invoke any Java objects, XML Web Services, or methods on the EJB.

• Synchronous and asynchronous method calls are supported.

• Does not require any modification on the server-side code, and does not require custom method attributes, special signatures, or parameter types. ★ Do not require a design-time build agent.

• Synchronous calls return data from the call, which does not need to be called back. An asynchronous invocation relies on a callback implementation.

• Any server-side method can be invoked synchronously or asynchronously.

• Client applications can request the specified activity mode to the server object. As a result, objects can be easily created without any special programming.

• Provides a specific API to handle database query results-server code can return data sets or data tables, and clients display this result with a special recordset JavaScript object. This object provides a method for retrieving column names and row data.

• Support data paging technology. The client application can retrieve data from the page.

• Supports all server-side parameter types and returns values-prototypes, strings, composite types, arrays, native. NET collections, remote references.

• A total of two versions available: Standard Edition (free) and Professional Edition (commercial license)

4.2 Echo 2 (since March 2005)

• Server-side Java libraries can be easily configured into all of the servlet 2.3+ matching containers.

• The client JavaScript library works in a variety of browsers that support Httpxmlrequest.

• Use JSON to marshal your Pojo data on the server side. This allows you to access remote data in any JavaScript environment (HTML,XUL,SVG), which can be easily implemented through hard coding or integration with a mature JavaScript library.

• Provides a simple interface to enable your JavaScript code to interact with remote Pojo (RPC, etc.) that is exposed to the client.

• Use the easy and flexible configuration of <servlet> and <filter> in Web.xml, and can (but not rely on) integrate with spring.
