Migrating to WebSphere Portal 6.1, PUMA API

There are some minor chages related to PUMA. To get the user and group information make these changes,

Usage of class com.ibm.portal.puma.User should be rpelaced with com.ibm.portal.um.User
and
com.ibm.portal.puma.Group should be rpelaced with com.ibm.portal.um.Group

List attributes = new ArrayList();
attributes.add("cn");
//Get User Name
PumaProfile userProfile = pumaHomeSvc.getProfile(PortletRequest);
PumaLocator locator = pumaHomeSvc.getLocator(PortletRequest);
com.ibm.portal.um.User wpUser = (com.ibm.portal.um.User) userProfile.getCurrentUser();

List attribUser = userProfile.getDefinedGroupAttributeDefinitions();
Map userAttributes = userProfile.getAttributes(wpUser,attributes);
String userName = (String) userAttributes.get("cn");

//Get Group
com.ibm.portal.um.Group wpGroup;
List groups = locator.findGroupsByPrincipal(wpUser, false);

for (Iterator i = groups.iterator(); i.hasNext();) {
wpGroup = (com.ibm.portal.um.Group) i.next();
Map groupAttributes = userProfile.getAttributes(wpGroup, attributes);
String groupName = (String) groupAttributes.get("cn");
}
