Access a Custom Java Object with JavaScript

Digg this   Post to del.icio.us

Abstract: This tutorial demonstrate how to use the DWR framework to access a JavaScript representation of a Java object from the server. Then displays the object on a web page.

The programming model for a number of Java applications involves generating JavaBeans that represent data. A JavaBean is an object representation of a concrete thing like a bicycle, with its wheels, pedals, seat, chain rings, and other components as object properties. The purpose of a JavaBean is to represent these concrete entities for a software program that accomplishes a set of practical tasks involving the entity data type, such as an e-commerce site that sells bikes. Therefore, it is natural that some Ajax applications will receive data from a server component in the form of JavaBeans.

This hack uses the DWR framework to access a JavaScript representation of a Java object from the server. The hack then displays the object on a web page.
