Request Bean Node - Sun Java Studio Creator 2

The Request Bean node in the Projects window lists the JavaBean objects that the application manages in request scope.

A typical use of the request bean is to add a property that will be used to store a value from the current page for use by the next page.

Use the Application Bean to store information that applies to all user sessions, such as an option list for a Drop Down component.
Use the Session Bean to store information for use by other pages throughout the user's session, such as the user's logon name.

To add a property to a request bean, right-click the node and choose Add > Property as described in Creating a Bean Property.

Note: The Request Bean is instantiated only if the page that initiates the request stores values in Request Bean properties. For example, an input component like Text Field has its text property bound to a Request Bean property.

Any value that you store in the Request Bean disappears as soon as the request ends. A request is a single transmission of an HTTP request from the client to the server plus the corresponding response, which can be another page. In most cases, the request begins with the clicking of a button or a link and ends with the response of an HTML page to be displayed.

You cannot use the Request Bean if you have included the <redirect> element inside <navigation-case> element of a navigation rule. When the page is submitted, the <redirect> element redirects the page and ends the request before a subsequent page can use any of the values stored in the Request Bean.

If you double-click the Request Bean node, a Java Editor opens to allow you to edit the RequestBean.java file. Do not edit this file unless you are an experienced developer.
