Re: [vysper][pubsub] Demo + Cheers!
Hi Michael, At first: Congratulations for successfully completing your GSoC09 project on time! It's been a pleasure for me to see you working on PubSub. I hope we see you working on Vysper in future. Now the demo. Yesterday I got it working. I removed the call to JTable.setFillsViewportHeight(boolean) because it is JDK 6 only. Then I found that subscribers are receiving every published message two times (at least it is displayed two times). Can you reproduce? Maybe you get that fixed one way or the other. Thanks for giving us PubSub, Bernd Michael Jakl wrote: Hi! The demo application has finally reached its feature complete state.

To try it, you have to start Vysper with the PubSub module loaded (put everything in the classpath and start with java org.apache.vysper.xmpp.server.ServerMain -Dvysper.add.module=org.apache.vysper.xmpp.modules.extension.xep0060_pubsub.PublishSubscribeModule for example). Sidenote: You have to use a version prior to rev802821 of vysper-core, and HEAD of the extension and the client (see my previous mail). The client is a simple Java Swing application and is run with the three smack libs on the classpath. For example on a *nix with ~/.m2 as Maven directory: java -classpath ~/.m2/repository/jivesoftware/smack/3.1.0/smack-3.1.0.jar:~/.m2/repository/jivesoftware/smackx/3.1.0/smackx-3.1.0.jar:~/.m2/repository/jivesoftware/smackx-pubsub/1.0-20090813101732-vysper/smackx-pubsub-1.0-20090813101732-vysper.jar org.apache.vysper.demo.pubsub.client.PubsubClientGUI As soon as the server closes, all data (nodes, items) will be lost. To see something interesting, you could open two or three clients with different users (don't forget to change the JID *and* the username), create a few nodes, subscribe to them and post messages back and forth. Currently only the owner is allowed to publish (and there is no possibility to grant permissions to other users ATM). I hope you enjoy it :) Cheers, Michael

[vysper][pubsub] Demo application + Maven
Hi! Slowly the code approaches a state where I'd like to upload it into the svn. I think it would make sense to mavenize it beforehand, but I need help for that. My program needs this: http://github.com/squaremo/smackx-pubsub/tree/master with its special install procedure. Maybe we could upload this one and its dependencies to Niklas' private Maven repo? Second, for Vysper to load my module, I'd need to give it a parameter. This requires that the pubsub module is on the classpath (pubsub needs vysper-core for building, but vysper-core needs pubsub for running if we want to load the pubsub module). How should I start with these requirements? I know a little Ant, but I've next to no experience with Maven. Thanks, Michael

Or, do you want Maven to launch the server for you? I'm confused :-) Um, me too :) Let's start at the beginning. I'd like to have a simple way of running the server and the client. I thought Maven might be the tool for that because it handles the dependencies, but maybe I was wrong? Running the server is not important, but running the client would be nice. How would you suggest to do it in a portable way? Maybe I've overcomplicated the whole thing. Running the server is easy from Eclipse and the demo is also easy to start as soon as the dependencies are there (with your repo. this should now be fully automatic). Sorry for the chaos.

My app is now available at Vysper/demo/pubsub/client. The app itself is far from complete. Only looking up all the nodes, subscriptions, and affiliations as well as susbscribing and unsubscribing to existing nodes is supported. There is currently no possibility to create nodes, receive messages, and send messages. Michael
