This section shows you how to create, update, and remove users from the portal via two ways:

You can follow the snippet below to list users and some information of the users:

 try {

      ListAccess<User> users = userHandler.findAllUsers();


      for (User user : users.load(0, users.getSize())) {

        writer.append("<dl class='dl-horizontal'>");


        //Print username and email

        writer.append("<dt>Username:</dt>");

        writer.append("<dd>" + user.getUserName() + "</dd>");

        writer.append("<dt>Email:</dt>");

        writer.append("<dd>" + user.getEmail() + "</dd>");


        //Print user profile

        UserProfile profile = profileHandler.findUserProfileByName(user.getUserName());


        for (Iterator<Map.Entry<String, String>> i =profile.getUserInfoMap().entrySet().iterator(); i.hasNext(); ) {

          Map.Entry<String, String> entry = i.next();

          writer.append("<dt>" + entry.getKey() + "</dt>");

          writer.append("<dd>" + entry.getValue() + "</dd>");

        }


        //Print group and membership of user

        Collection<Group> groups = groupHandler.findGroupsOfUser(user.getUserName());

        writer.append("<dt>Roles:</dt>");

        for (Group group : groups) {

          Collection<Membership> memberships =  membershipHandler.findMembershipsByUserAndGroup(user.getUserName(), group.getId());

          StringBuilder sb = new StringBuilder();

          for (Iterator<Membership> i = memberships.iterator(); i.hasNext(); ) {

            sb.append(i.next().getMembershipType());

            if (i.hasNext()) sb.append(',');

          }

          writer.append("<dd>" + sb.toString() + " in group <i>" + group.getId() + "</i></dd>");

        }

        writer.append("</dl>");

      }


    } catch (Exception e) {

      e.printStackTrace();

    }

The users list is displayed like this in your product:

Creating a user

Create a portlet action, then add the snippet below to it.

User newUser = userHandler.createUserInstance("newuser");

newUser.setPassword("exo");

newUser.setOrganizationId("/platform/users");

newUser.setDisplayName("New User");

newUser.setEmail("user@exoplatform.com");

userHandler.createUser(newUser, false);


Group group = groupHandler.findGroupById("/platform/users");

membershipHandler.linkMembership(newUser, group, membershipTypeHandler.findMembershipType("member"), false);

        

Executing the portlet action allows creating a user called newuser whose role is member:/platform/users.

Removing a user

Create a portlet action which executes the snippet below to remove an initialized user, for example, newuser.

userHandler.removeUser("newuser", false);

Removing a membership

Create a portlet action which executes the snippet below to remove a membership of the custom user:

Membership membership = membershipHandler.findMembershipByUserGroupAndType("custom", "/organization/custom", "custom-membership");

    membershipHandler.removeMembership(membership.getId(), false);
