http? (Topic: Add jbother nightly source code in Download Section of jbother.org)

rs_ts — Tue, 18 Oct 2005 21:27:02 +0100

I can't connect to the SVN repository either because of our company's firewall. I'm still new to SVN, but I've seen some repositories that are accessible through port 80 instead of the svn port. I tried connecting to /usr/local/svn/JBother using TortoiseSVN but was unsuccessful.

Is it possible to get access to the JBother repository through port 80?

Thanks

Any progress on this integration? Would be great to have it in JBrother.

Re: Kiosk mode

VisualEcho — Mon, 10 Oct 2005 22:57:21 +0100

Okay, I found a place in JBotherLoader.java which goofs the change to the base settings directory. Basically, in kiosk mode, the loader sets the base settings directory to /.jbother_ rather than /.jbother . This is done to keep from overwriting the regular configuration when JBother is used outside of kiosk mode. I'll email the patch to Synic.

I'm working on some better kiosk mode docs and implementation examples, will send them in when I get them right.

Starting a private chat (Jbother parameters or custom development feature?)

toolz — Fri, 07 Oct 2005 00:36:35 +0100

My needs are simple. I want to start a one-on-one chat window to be shared by two users only. One user will invite another to chat, the chat window will open, and the other user can choose to join the chat. These two chatters will not see any other chatters or groups on the system. I have my own jabber server running and will authenticate the users for them by using their usernames and passwords from a database. If jbother is not capable of this using parameters, I would not mind paying someone to hack it to do this. I am a unix systems and CGI C and Perl kinda programmer, not Java.

speaking of which... (Topic: Kiosk mode)

jaspax — Mon, 03 Oct 2005 23:14:43 +0100

This looks very interesting, and very similar to something that I am working on.

My overall situation is different, however: I'm looking to have the user download a JBother client that will automatically log in with the username/password supplied, but which creates a persistent account that the user will log in with every time.

This might require a little bit of source modification, and the end result might not be useful for anyone other than me, but I'll post about it here.

Okay... sorry... (Topic: Kiosk mode)

VisualEcho — Fri, 30 Sep 2005 16:13:46 +0100

Sorry, I got distracted, the weather got warm and the women around here temporarily stopped wearing bulletproof parkas. I'll pull down a fresh copy of the source tree and send a new patch soon, with lots of docs.

For the kiosk mode, you create a JNLP file with a few additional parameters, which include a username from another authentication system. I've got this working with phpBB bulletin boards, a system I'm familiar with, but could easily be incorporated into other mechanisms in a similar way. Here's a sample JNLP:

[code]

    Vault of Midnight Chat Room
    JBother Jabber Client

    JBother is a Jabber client written in Java

      webstart
    kiosk=blahblahblah
    kiosk_nick=Visual+Echo
    kiosk_user=vm_Visual+Echo_3
    kiosk_pass=we ir d oc te t se qu nc e
    kiosk_roompass=n0tTh3R341p455W3rd
    kiosk_roomservice=private.jabber.mdve.net

[/code]

The supporting script acquires the username of the authenticated user, inserts/updates the user into the jabber server MySQL database, deletes old JNLP files, writes the new JNLP file, and serves a location redirect to that file. Here is my example for phpBB:

[code]

$realm = 'jabber.mdve.net';
$chat_service = 'private.jabber.mdve.net';
$room_name = "blahblahblah";
$room_password = "n0tTh3R341p455W3rd";

$name_prefix = 'ZQ_';
$jabber_dbhost = 'localhost';
$jabber_dbname = 'jabberd2';
$jabber_dbuser = 'jabberd2';
$jabber_dbpasswd = '4n0th3R6adP455w0rD';

(I didn't write all of this, I just know it works)

I'm not sure if anything broke with the new versions, I'll check it out. When I left off, there were a couple of things still left to do... like remove the roster panel (not needed in kiosk mode, no other contacts are available other than the ones in the room already). I think the security I put in is sufficient as long as nobody filches the JNLP file or it's name from your machine... but I wouldn't mind more suggestions on what might improve that too.

Re: Processing Custom Packets

You can - inside a plugin you have access to the XMPPConnection instance via BuddyList.getInstance().getConnection() - where you can add IQ packet listeners, etc.

Processing Custom Packets

ldodds — Thu, 15 Sep 2005 10:59:19 +0100

Is it possible to write a JBother plugin that will handle custom IQ packets?

I want to be able to send/receive custom data. I have prototype code available that successfully does this using the Smack API directly, registered a custom packet listener.

Can I do this within a JBother plugin, or would I need to integrate this into the code itself?

Are there any examples of this kind of usage already?

Thanks for any help/pointers.

Take a look at boolean setStatus() in com.valhalla.jbother.BuddyList - if you try to set a status that's not "offline", it connects you to the server. At the bottom of the method, you'll see it uses the singleton of ConnectorThread to connect to the server.

Re: Stand alone Chat

You would have to connect to the server with a preset username and password first... and make it so the roster never shows. Possibly present a JOptionPane asking for their desired nickname as well.

Stand alone Chat (Just start the Group Chat)

mope — Tue, 23 Aug 2005 06:12:33 +0100

Hello,

I am looking for a way to implement this feature:

When the JAR File is opened I just want to join a group chat on a specific server with fixed values. I don't want to see the messaging window or something else and when I close the group chat window, the programme should also be closed.

How can I do this?

I have already tried to add this code in JBotherLoader.afterSplash:

      ChatRoomPanel window = new ChatRoomPanel("chatroom" + "@"
      + "server.com", "test", "test");
      window.startChat();

but it doesn't work.

Can somebody please tell me the correct code or an other possibility to achieve this?

Chat Only (Nur im Gruppen Chat)

mope — Mon, 22 Aug 2005 11:14:27 +0100

Hallo,

Ich möchte gerne folgende Funktionalität:

Wenn ich auf die JAR - Datei klicke, soll sich nur das Gruppenchatfenster mit fixen Werten öffnen. Wenn ich das Fenster schließe, soll sich das gesamte Programm schließen.

Das Hauptfenster oder andere, sollen gar nicht angezeigt werden.

Wie erreiche ich das?

Ich habe versucht, im Source Code in JBotherLoader --> afterSplash diese Zeilen am Anfang einzufügen:

      ChatRoomPanel window = new ChatRoomPanel("chatroom" + "@"
      + "server.com", "test", "test");
      window.startChat();

nur leider funktioniert das überhaupt nicht so wie es soll, es hängt dann nämlich.

Kann mir jemand den korrekten Code sagen, bzw. eine leichtere Möglichkeit, dies zu erreichen?
