The JSP integration in OpenCms

This part of the documentation describes the basics of JSP application development with OpenCms. It provides an overview and some background information about the technology used for the OpenCms JSP integration. Other modules available in the Alkacon OpenCms documentation accompany this introduction and serve as further reference material. 

Please note that this is not an introduction to JSP developing, there are certainly many good tutorials or books for that around.

The JSP integration part in OpenCms is called Flex. So if we talk about an OpenCms/Flex or just a Flex application, we actually mean a JSP application built with OpenCms. The name Flex was chosen because the ultimate goal of the JSP integration was to make OpenCms more flexible to use. We think that we have achieved that goal. But judge for yourself...

Features of the JSP integration in OpenCms:

  • Add and manage JSP in the OpenCms Workplace
  • Supports WYSIWYG editable pages which use JSP templates
  • Use the same JSP template for editable pages and interactive forms
  • JSP Taglib for common OpenCms tasks
  • JSP API to directly access OpenCms functionality
  • Separate online and offline versions of the same JSP
  • Introducing the FlexCache, a powerful declarative caching mechanism
  • Optional output streaming on a per-page basis
  • Optional static export of JSP
  • Full interoperability with OpenCms legacy XMLTemplates

About these pages
