[JDEV] Subscribe / Unsubscribe users

[Leon Kwan]

Hello all genius,

I met great problem in subscribing and unsubscribing users
when using jabberbeans API.

Below is the code of subscribe and unsubscribe.

In subscribe method, I found that I can put the the
subscribed name to the xml of the user profile but I
cannot set the waiting state type to "subscribe".
In the packet listener, I can see the packet sent
contains this attribute of "waiting state type".
So what is the proper procedure of adding a user?

Moreover, exception occurs when request the roster list if
one of the roster element is "ask=subscribe". How should
I handle it?

Unsubscribe is worse. Although I found that the packet
sent contains attribute of "waiting state type" and also
the "subscription type", nothing in the xml of the
user profile is changed.

 public boolean subscribe(String username)
 {
  RosterItemBuilder rib=new RosterItemBuilder();
  rib.setJID(createJID(username));
  rib.setSubscriptionType("both");
  rib.setWaitingStateType("subscribe");
  rib.setFriendlyName(username);

  InfoQueryBuilder iqbuild = new InfoQueryBuilder();

  RosterItem ri;
  try
  {
   ri = (RosterItem) rib.build();
   RosterExtensionBuilder reb = new RosterExtensionBuilder();
   reb.addRosterItem(ri);
   reb.setIQRoster(true);
   iqbuild.reset();
   iqbuild.setType("set");
   iqbuild.addExtension(reb.build());
      //build and send presence
      connection.send(iqbuild.build());
  }
  catch (InstantiationException e)
  {
   e.printStackTrace(System.err);
      return false;
  }
  return true;
 }



 public boolean remove(String username)
 {
  RosterItemBuilder rib=new RosterItemBuilder();
  rib.setJID(createJID(username));
  rib.setSubscriptionType("both");
  rib.setWaitingStateType("unsubscribe");
  rib.setFriendlyName(username);

  InfoQueryBuilder iqbuild = new InfoQueryBuilder();

  RosterItem ri;
  try
  {
   ri = (RosterItem) rib.build();
   RosterExtensionBuilder reb = new RosterExtensionBuilder();
   reb.addRosterItem(ri);
   reb.setIQRoster(true);
   iqbuild.reset();
   iqbuild.setType("set");
   iqbuild.addExtension(reb.build());
      //build and send presence
      connection.send(iqbuild.build());
  }
  catch (InstantiationException e)
  {
   e.printStackTrace(System.err);
      return false;
  }
  return true;
 }
