Introduction
In NetUI, data binding allows JSP tags or other UI technologies to read and write data available in the web-tier environment. This document discusses both the implicit objects that are available via NetUI to the JSP author and the expression languages that are used to bind UI objects to those implicit objects.
NetUI tags support binding to both read-only and read-write data. Read-only data is usually bound to tag attributes that simply display information on a page. Read-write data is bound with the intention of being updated from a
Data binding is a process that allows an Internet user to manipulate Web page elements using a Web browser. It employs dynamic HTML (hypertext markup language) and does not require complex scripting or programming. Data binding first became available with Microsoft Internet Explorer (MSIE) version 4. It can be used in conjunction with that and all subsequent versions of MSIE to create and view interactive Web sites with a minimum demand on authoring time, subscriber effort, server drive space, and server processing resources.
The data binding
Databinding has to be just about one of the coolest features in Flex 2, allowing you to bind a property to the value of a property of another object. When the property of that object is updated, the value of the bound property will automatically be updated. This is mainly used in Flex to update UI components when the data for the model changes.
Unfortunately databinding doesn't work for read-only properties. A read-only property (by my definition) is a private instance variable of a class that has a getter function without a matching setter function.
XML data binding refers to the process of representing the information in an XML document as an object in computer memory. This allows applications to access the data in the XML from the object rather than using the DOM to retrieve the data from a direct representation of the XML itself.
An XML data binder accomplishes this by creating a mapping between elements of the XML schema of the document we wish to bind and members of a class to be represented in memory.
When this process is applied to convert an XML document to an object, it is called
