1. Using Spring to get the service for your class (e.g. YourAppClass) (recommended)
   1. Add the AuthzGroupService bean to the bean for YourAppClass

      Code Block
      xml xml
      <bean id="org.sakaiproject.yourapp.logic.YourAppClass" class="org.sakaiproject.yourapp.logic.impl.YourAppClassImpl"> <property name="authzGroupService" ref="org.sakaiproject.authz.api.AuthzGroupService" /> </bean>

   2. Add a variable and setter to YourAppClass to use the service in like so:

      Code Block
      java java
      private AuthzGroupService authzGroupService; public void setAuthzGroupService(AuthzGroupService authzGroupService) { this.authzGroupService = authzGroupService; }

2. Using the cover Component Manager to get the service
   • Note: This is not the recommended method, you should be using Spring to inject the service
   1. Setup a variable to hold the instance from the cover Use the CM cover to get the service

      Code Block
      java java
      import org.sakaiproject.component.cover.ComponentManager; import org.sakaiproject.authz.api.AuthzGroupService; ... private AuthzGroupService authzGroupService;

      Get access to the service using the cover

      Code Block
      java	java	... authzGroupService = (AuthzGroupService) org.sakaiproject.authz.cover.ComponentManager.get(AuthzGroupService.getInstance(class);

Getting the users associated with a site which have a specific permission

...

java.util.Set authzGroupIds = authzGroupService.getAuthzGroupsIsAllowed(userId, "tool.permission", null); // (1)
java.util.Iterator it = authzGroupIds.iterator(); // (2)
while (it.hasNext()) {
   String authzGroupId = (String) it.next();
   Reference r = entityManager.newReference(authzGroupId); // (3)
   if(r.isKnownType()) {
      if(r.getType().equals(SiteService.SITEAPPLICATION_SUBTYPEID)) { // (4)
         // do something since this is a site
         String siteId = r.getId();
         String context = r.getId();
         try {
            Site site = siteService.getSite(siteId);
         } catch (IdUnusedException e) {
            // invalid site Id returned
            throw new RuntimeException("Could not get site from siteId:" + siteId);
         }
      } else if (r.getType().equals(SiteService.GROUP_SUBTYPE)) { // (5)
         // do something since this is a site group
         String groupId = r.getId();
         String context = r.getId();
         Group group = siteService.findGroup(groupId);
         if (group != null) {
            // found a valid group so do something
         }
      }
   }
}
