WebCenter Portal provides various built-in assets that users can leverage in their portals. Copies of these built-in assets can be modified within WebCenter Portal to meet specific local requirements. For more information about modifying built-in assets in WebCenter Portal, see Creating Assets in Building Portals with Oracle WebCenter Portal.

Some assets, such as page styles and layouts, cannot be created in WebCenter Portal. These resources must be created in JDeveloper and deployed to WebCenter Portal. In some cases, WebCenter Portal may also not be able to add all the required functionality.

WebCenter Portal assets rely on three application templates that can be used to create or modify asset applications in JDeveloper:

• WebCenter Portal Asset template – used to create or modify assets for page templates, skins, layouts, page styles, Content Presenter templates, and Visualization templates. The resulting asset applications include a default WebCenter Portal Asset Archive deployment profile that you can use to deploy the asset to WebCenter Portal across a Portal Server connection. For more information about creating an asset application for these types of assets, see Working with the WebCenter Portal Asset Application Template.

• WebCenter Portlet Producer Application template – used to develop portlets based on the JSR 286 standards. For more information, see Introduction to Portlets.

• WebCenter Portal Server Extension template – used to develop extensions to WebCenter Portal Server. For more information about developing extensions for Portal Server, see Developing Shared Libraries.
