I needed to develop an iView which shows role content in SAP NetWeaver Portal. I just wanted to share my approach with the community. Here is what you need to do:
- In Development Infrastructure Perspective, create a Development Component with type Portal Application Standalone
- In your development component add references to
- ENGFACADE tc/je/usermanagement/api
- EP-BASIS-API tc/epbc/pcd/gl/api
- Switch to Enterprise Portal Perspective and create a new Portal Application Object, with DynPage type and an arbitrary name (e.g. in RoleContent)
- Upload images for role hierarchy Folder.gif, iView.gif, Page.gif, Role.gif, and Role.gif. You may download them from below respectively:
- Adjust dist/PORTAL-INF/portalapp.xml and add parameter TargetRoleName. This will appear in iView properties, thus you can enter role unique name to be displayed. Your xml content will look like:
<?xml version="1.0" encoding="utf-8"?>
<application>
<application-config>
<property name="PrivateSharingReference" value="com.sap.portal.htmlb"/>
</application-config>
<components>
<component name="RoleContent">
<component-config>
<property name="ClassName" value="com.saptr.portal.RoleContent"/>
</component-config>
<component-profile>
<property name="TargetRoleName" value="pcd:portal_content/administrator/super_admin/super_admin_role"/>
</component-profile>
</component>
</components>
<services/>
</application>
- You will have a java class with name like RoleContentDynPage. Copy and paste codes in corresponding methods and adjust imports.
