Hello!
Check http://enapso.org/jwsForum219/posts/list/15619.page
You just need to import the package org.jwebsocket.config.JWebSocketConfig and add the following lines:

// the following line must not be removed due to GNU LGPL 3.0 license!
JWebSocketFactory.printCopyrightToConsole();
// check if home, config or bootstrap path are passed by command line
JWebSocketConfig.initForConsoleApp(aArgs);

Hello, the link to the sources is broken, can you fix it? I have tried to follow the tutorial, but i only got this error:
java.lang.NullPointerException
at org.jwebsocket.factory.JWebSocketFactory.start(JWebSocketFactory.java:119)
That exception is throwed in this line:

I’m runing in a machine with linux, netbeans 7.0.1, java 1.6 and i I’ve set up the environment variable:
JWEBSOCKET_HOME = “/home/user/programs/jWebSocket-1.0″ and
PATH=:$JWEBSOCKET_HOME/bin

Can you help me?

Thanks!

Hello,
I have implemented this jWebsockt earlier but encounter some problems after the protocol update by Google.
You seem to have a good and simple implementation, but when trying it I encounter the compile error :

Note: C:\Test\MyjWeSocketJavaClient\src\nl\amis\jws\JwebSockClient.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
compile:
Created dir: C:\Test\MyjWeSocketJavaClient\dist
Copying 1 file to C:\Test\MyjWeSocketJavaClient\build
C:\Test\MyjWeSocketJavaClient\nbproject\build-impl.xml:714: The following error occurred while executing this line:

I have not used much time trying to resolve this problem. Normally I just expect things to work.
Anyway. It seems that you are right. Implementing a jWebsocket server is still not straightforward.
