Oracle WebCenter Suite is a set of tools and services for building composite applications that promote user productivity by delivering a dynamic, context-aware user experience that integrates structured and unstructured content, business processes, business intelligence, communication and collaboration services.

WebCenter Framework provides a runtime environment for your WebCenter applications.  You can build WebCenter applications using the WebCenter Framework Extension for JDeveloper.  The extension provides a declarative environment to build portlets, consume portlets, access content, and customize your pages at runtime. All of these components are available to your JavaServer Faces application. Key features include:

• Embed portlets in your Faces applications (both JSR 168/WSRP 2.0 and Oracle PDK-Java)
• Integrate content repositories using the JCR 1.0 standard
• Embed customizable components to enable runtime customization of your applications
• Secure your applications using declarative wizards
• Embed publishing components to allow business users to publish content at runtime
• Export your Faces applications as portlets

WebCenter Services include additional services (e.g. Discussions and Wiki) that can be included in your WebCenter applications.  Please see the Oracle WebCenter Suite page on OTN for more information.
