Jetspeed is an Open Source implementation of an Enterprise Information Portal, using Java and XML. A portal makes network resources (applications, databases and so forth) available to end-users. The user can access the portal via a web browser, WAP-phone, pager or any other device. Jetspeed acts as the central hub where information from multiple sources are made available in an easy to use manner.
The data presented via Jetspeed is independent of content type, This means that content from for example XML,RSS or SMTP can be integrated with Jetspeed. The actual presentation of the data is handled via ates XSL and delivered to the user for example via the combination of Java Server Pages (JSPs) and HTML. Jetspeed provides support for templating and content publication frameworks such as Cocoon , WebMacro and Velocity . Note that outside of regular browser Jetspeed also supports WAP devices.
Jetspeed helps you build portal applications quickly. The goal is to make Jetspeed a tool for both portal developers as well as user interface designers. Currently the focus is on providing developers with a set of tools that facilitates building the base for the portal. With Jetspeed you can quickly build an XML portal and also syndicate your own content.
