Display iViews, pages, roles

[Former Member]

Hi All,

We have a requirement in Webdynpro. Here is the requirement.

1) We need to get the list of available iViews, roles, pages, and worksets from the server.

2)We need to display those.

My question is how to get the list of available iViews, roles, pages, and worksets. I am able to get the availabale roles using the code given by sap, but I am not able to get others. Is anybody have the code related to the above requirement.

Hi EP Developer,

Alternatively, you can go through <a href="/people/prakash.singh4/blog/2005/07/28/browse-roles-folders-pages-iviews-assigned-to-a-user-ep6-sp9-and-higher weblog for your reference.

Thanks and Regards,

Portalapp.xml should look following.

<?xml version="1.0" encoding="utf-8"?>
<application>
  <application-config>
    <property name="PrivateSharingReference" value="com.sap.portal.htmlb,com.sap.portal.pcd.glservice,com.sap.portal.pcmbuilderservice"/>
  </application-config>
  <components>
    <component name="display">
      <component-config>
        <property name="ClassName" value="com.ust.browserole.display"/>
        <property name="SecurityZone" value="com.ust.browserole/high_safety"/>
      </component-config>
      <component-profile/>
    </component>
  </components>
  <services/>
</application>

Hi,

Thanks for your code. I already have this code from one blog. But the requirement is in webdynpro. I am able run the application in webdynpro also, I am facing the issue with usermanagement engine code, here is the code

IUserManagementEngine ume = (IUserManagementEngine) PortalRuntime

.getRuntimeResources().getService( IUserManagementEngine.KEY);

How can I achieve this one in webdynpro.
