Introduction to the Flex JSP tag library

Flex includes a tag library that you can use with JavaServer Pages (JSPs). The Flex JSP tag library does the following:

• Supports inlined, dynamically generated MXML
• Generates an HTML wrapper for compiled MXML applications
• Generates an HTML wrapper for static SWF files

When you use the Flex JSP tag library, you have access to all of the objects on JSPs to dynamically generate the MXML from a combination of MXML and JSP tags.

For example, suppose you run a weather service that stores a ZIP code or geocode in your user's session object. Based on this geocode, you dynamically invoke a regional weather web service. Because you can write a Flex application in a JSP, you can access the session data and assign the proper web service before the MXML is compiled.

The Flex JSP tags are integrated with the following Flex features:

• Caching
• History management
• Accessibility
• Player deployment
• Player version detection

The Flex JSP tag library also generates the HTML wrapper around your Flex applications. As a result, you can use it to set flashVars or other properties of the <object> and <embed> tags.
