irc followup: let's try JXTA

To follow up to my previous blog about the desire for irc.java.net, I'd like to talk about using Project JXTA in the interim (and perhaps indefinately, if people like it) to fill the gap.

Shortly after posting the above blog, I was contacted by James Todd about the possibility of using MyJXTA as a distributed chat service. I tried it out, and it seems to fit the bill pretty well.

So, I've created a public jxta group called jsfaces. You can join by using Java WebStart and clicking on this link.

In my opinion, the number one advantage JXTA has over old school IRC is the ability to easily tunnel through HTTP using the standard java control panel proxy settings. In this way companies like Oracle, with firewalls that only permit HTTP to traverse, can participate in the chat.

I hope to see you all in the jsfaces chat room!

In any case, please continue to vote for irc.java.net, even if you try out JXTA.

  Not on OSX Tiger 10.4 with JDK 1.5

  An error occurred while launching/running the application.

  Title: MyJXTA
  Vendor: MyJXTA
  Category: Unexpected Error

  Unexpected exception: java.lang.reflect.InvocationTargetException

  I heart cross-platform paradigms!

• Actually, I'm running on 10.4 with JDK 1.5 as well right now and I'm on line.
  Did you modify your java control panel so that 1.5 runs ok?

  I launched the jnlp from firefox.

  Let me try it from Safari....

  Well, it started ok from Safari too. What are you java console settings? Make sure the proxies are set properly for your organization.

• we're definitely interested in hearing folks input. i haven't seen that invocation target exception before. myjxta requires jre 1.4.2+. one of the deployment options is jnlp. others include binary and source. i am working on a jnlp optimized distribution that proves quite promissing from a performance perspective.
  i run osx/tiger 10.4 and jre 1.4.x at home and the jnlp distribution works fine. so fine, my 4yr old son is the one often on that system im'ming me via myjxta :)

• As long as JXTA does not by default do autoconfiguration, this will not be ready for primetime I am affraid, as it will limit JXTA usage to the Java geeks we are ;-)

  So please anybody, work on autoconfiguration ASAP to push JXTA !

  Imagine the power of P2PSocket with autoconfiguration enable by default. You have a universal way of doing P2P ou-of-the-box ready applications !!! Great potential IMHO !

• Can you please elaborate on what you mean by doing autoconfiguration by default? I'm new to JXTA.

  P.S. I make a habit of always being in the jsfaces group now.

• re "jxta autoconfig" please consider ext:config:

  http://wiki.java.net/bin/view/Jxta/ExtConfig

  to see ext:config in action try out myjxta, via webstart:

  http://download.jxta.org/build/nightly/jnlp/myjxta.jnlp

  compilable/runnable (read ant is included) ext:config code samples are included in the resources section of the afore mentioned wiki entry.
  re "sockets" please consider:

  net.jxta.socket.JxtaSocket
  and net.jxta.socket.JxtaServerSocket

  JxtaSocket is a literal implementation of java.net.Socket thereby providing a trivial means to try out existing Socket based code over a JXTA Network, primarily via the need to only change the associated constructor ... or, by augmenting the default SocketFactory. here's the javadoc:
