Seeded Customizations

Seeded customization of an application is the process of taking a generalized application and making modifications to suit the needs of a particular group, such as a specific industry or site.

When Seeded Customizations is enabled in a project's properties, JDeveloper uses the Oracle Metadata Services (MDS) framework to store customized metadata objects in a metadata repository and retrieve them at runtime to reveal the customized application.

When you click OK in the Project Properties dialog, JDeveloper updates web.xml with the necessary configuration elements for using MDS customizations:

                               
<context-param>
  <param-name>oracle.adf.jsp.provider.0</param-name>
  <param-value>oracle.mds.jsp.MDSJSPProviderHelper</param-value>
</context-param>
