Hi List,<br><br>Only just joined, im not sure if this is the right place to post or not so let me know if it isnt.<br><br>Im trying to use JGroups in a project. <br><br>First things first tried running a very simple example but couldnt get the two machines to talk to each other, i read all the documentation but still couldnt work out why.<br>
<br>I tried using the webstart demo of the draw (found here <a href="http://www.jgroups.org/demos.html">http://www.jgroups.org/demos.html</a>) thats actually the replicatedcache demo and to my surprise it worked.<br><br>I downloaded the .jar that the jnlp uses and ran it from the command line and got:<br>
<br><br>---------------------------------------------------------<br>GMS: address is <a href="http://192.168.1.69:54939">192.168.1.69:54939</a> (cluster=replcache-cluster)<br>---------------------------------------------------------<br>
<br><br><br>Now when I tried to run the ReplCacheDemo from within the jgroups-all.jar I get the following:<br><br><br><br>java -cp jgroups-all.jar org.jgroups.demos.ReplCacheDemo<br><br>14-Dec-2009 20:17:24 org.jgroups.logging.JDKLogImpl info<br>
INFO: JGroups version: 2.8.0.CR7<br><br>-------------------------------------------------------------------<br>GMS: address=M-Win7-38823, cluster=replcache-cluster, physical address=fe80:0:0:<br>0:69e5:8edf:3e90:e817:62330<br>
-------------------------------------------------------------------<br><br><br>So im not sure whats going on here, it looks like the jnlp demo is using a different GMS (?) settings to the one in jgroups-all.jar, so I tried to take the udp.xml file from the jnlp jar and use it in a simple example and I get the follwing errors:<br>
