Role adminRole = RoleLocalServiceUtil.getRole(themeDisplay.getCompanyId(),"Administrator");
List<User> adminUsers = UserLocalServiceUtil.getRoleUsers(adminRole.getRoleId());
PrincipalThreadLocal.setName(adminUsers.iterator().next().getUserId());
PermissionChecker checker =PermissionCheckerFactoryUtil.create(adminUsers.iterator().next());
PermissionThreadLocal.setPermissionChecker(checker);

 // Start your code
This example pulls list of site templates
List<LayoutSetPrototype> layoutSetPrototypes = LayoutSetPrototypeServiceUtil.search(company.getCompanyId(), Boolean.TRUE, null);
//End your code
PermissionThreadLocal.setPermissionChecker(currentPermisionChecker);
