There is an update version of this documentation for WebSphere Portal 8.5 in the Portal 8.5 Knowledge Center.

Expression Language (EL) beans are available for accessing WebSphere Programming models. These beans are accessed through the PortalBean represented in the global namespace by wp.

The beans documented below provide access to Portal's models and associated classes. For more information on specific models, refer to the Portal 8.0 SPI Javadoc .

PortalBean

The PortalBean provides access to EL Beans that represent some of Portal's models. You can use these models to access resource information in your jsps.

Example

To access the current user:

${wp.user}

Available accessors in the PortalBean (wp):

• ac - AccessControlRuntimeModelBean - Provides read access to the current access control permissions for a resource.
• clientProfile - ClientProfileBean - Provides access to the client profile.
• identification - IdentificationBean - Provides access to the identification services serialize and deserialize methods.
• languageList - LanguageListBean - Provides access to the interface representing a container in a layout model.
• layoutModel - LayoutModelBean - Provides access to the tree model representation of the layout of a page.
• localizedDescription - DescriptionBean - Provides access to the description of an object in the current locale.
• metadata - AggregatedMetatdataProviderBean - Provides access to the metadata for a specified resource.
• navigationModel - NavigationModelBean - Provides access to the navigation model.
• rep - ResourceEnvironmentProviderAccessorBean - Provides access to the set of configuration entries for the specified resource environment provider.
• selectionModel - NavigationSelectionModelBean - Provides access to a selection model for a navigation model.
• themeConfig - ThemeConfigBean - Encapsulates the theme "configuration" parameter lookup process.
• themeList - ThemeListBean - Provides access to list of theme objects.
• title - TitleBean - Provides access to the title of the currently rendered page or the title information set by a portlet.
• user - UserBean - Provides access to the active user
