Hi List, Only just joined, im not sure if this is the right place to post or not so let me know if it isnt. Im trying to use JGroups in a project. 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. I tried using the webstart demo of the draw (found here http://www.jgroups.org/demos.html) thats actually the replicatedcache demo and to my surprise it worked. I downloaded the .jar that the jnlp uses and ran it from the command line and got: --------------------------------------------------------- GMS: address is 192.168.1.69:54939 <http://192.168.1.69:54939> (cluster=replcache-cluster) --------------------------------------------------------- Now when I tried to run the ReplCacheDemo from within the jgroups-all.jar I get the following: java -cp jgroups-all.jar org.jgroups.demos.ReplCacheDemo 14-Dec-2009 20:17:24 org.jgroups.logging.JDKLogImpl info INFO: JGroups version: 2.8.0.CR7 ------------------------------------------------------------------- GMS: address=M-Win7-38823, cluster=replcache-cluster, physical address=fe80:0:0: 0:69e5:8edf:3e90:e817:62330 ------------------------------------------------------------------- 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: 14-Dec-2009 21:12:12 org.jgroups.logging.JDKLogImpl info INFO: JGroups version: 2.8.0.CR7 Exception in thread "main" org.jgroups.ChannelException: unable to setup the protocol stack at org.jgroups.JChannel.init(JChannel.java:1706) at org.jgroups.JChannel.<init>(JChannel.java:243) at org.jgroups.JChannel.<init>(JChannel.java:226) at jgroupssimple.Main.main(Main.java:25) Caused by: java.lang.Exception: unable to load class for protocol (either as an absolute - - or relative - org.jgroups.protocols. - package name)! at org.jgroups.stack.Configurator$ProtocolConfiguration.createLayer(Configurator.java:1244) at org.jgroups.stack.Configurator$ProtocolConfiguration.access$000(Configurator.java:1135) at org.jgroups.stack.Configurator.createProtocols(Configurator.java:368) at org.jgroups.stack.Configurator.setupProtocolStack(Configurator.java:88) at org.jgroups.stack.Configurator.setupProtocolStack(Configurator.java:54) at org.jgroups.stack.ProtocolStack.setup(ProtocolStack.java:452) at org.jgroups.JChannel.init(JChannel.java:1702) ... 3 more Java Result: 1 BUILD SUCCESSFUL (total time: 0 seconds) Anyone any clues as to whats going on here?

Your best bet is to use the JGroups user mail list javagroups-users(a)lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/javagroups-users On 12/14/2009 03:24 PM, Ales Justin wrote: > Try the forums, user forums in particular. > * http://community.jboss.org/ > > mike cann wrote: >> Hi List, >> >> Only just joined, im not sure if this is the right place to post or not >> so let me know if it isnt. >> >> Im trying to use JGroups in a project. >> >> 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. >> >> I tried using the webstart demo of the draw (found here >> http://www.jgroups.org/demos.html) thats actually the replicatedcache >> demo and to my surprise it worked. >> >> I downloaded the .jar that the jnlp uses and ran it from the command >> line and got: >> >> >> --------------------------------------------------------- >> GMS: address is 192.168.1.69:54939<http://192.168.1.69:54939> >> (cluster=replcache-cluster) >> --------------------------------------------------------- >> >> >> >> Now when I tried to run the ReplCacheDemo from within the >> jgroups-all.jar I get the following: >> >> >> >> java -cp jgroups-all.jar org.jgroups.demos.ReplCacheDemo >> >> 14-Dec-2009 20:17:24 org.jgroups.logging.JDKLogImpl info >> INFO: JGroups version: 2.8.0.CR7 >> >> ------------------------------------------------------------------- >> GMS: address=M-Win7-38823, cluster=replcache-cluster, physical >> address=fe80:0:0: >> 0:69e5:8edf:3e90:e817:62330 >> ------------------------------------------------------------------- >> >> >> 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: >> >> >> >> 14-Dec-2009 21:12:12 org.jgroups.logging.JDKLogImpl info >> INFO: JGroups version: 2.8.0.CR7 >> Exception in thread "main" org.jgroups.ChannelException: unable to setup >> the protocol stack >> at org.jgroups.JChannel.init(JChannel.java:1706) >> at org.jgroups.JChannel.<init>(JChannel.java:243) >> at org.jgroups.JChannel.<init>(JChannel.java:226) >> at jgroupssimple.Main.main(Main.java:25) >> Caused by: java.lang.Exception: unable to load class for protocol >> (either as an absolute - - or relative - org.jgroups.protocols. - >> package name)! >> at >> org.jgroups.stack.Configurator$ProtocolConfiguration.createLayer(Configurator.java:1244) >> at >> org.jgroups.stack.Configurator$ProtocolConfiguration.access$000(Configurator.java:1135) >> at >> org.jgroups.stack.Configurator.createProtocols(Configurator.java:368) >> at >> org.jgroups.stack.Configurator.setupProtocolStack(Configurator.java:88) >> at >> org.jgroups.stack.Configurator.setupProtocolStack(Configurator.java:54) >> at org.jgroups.stack.ProtocolStack.setup(ProtocolStack.java:452) >> at org.jgroups.JChannel.init(JChannel.java:1702) >> ... 3 more >> Java Result: 1 >> BUILD SUCCESSFUL (total time: 0 seconds) >> >> >> >> Anyone any clues as to whats going on here? >> Cheers for your time :) >> Mike >> >> >> >> >> >> -- >> Mike Cann >> http://www.mikecann.co.uk/ >> http://www.artificialgames.co.uk/ >> >> >> ------------------------------------------------------------------------ >> >> _______________________________________________ >> jboss-development mailing list >> jboss-development(a)lists.jboss.org >> https://lists.jboss.org/mailman/listinfo/jboss-development > _______________________________________________ > jboss-development mailing list > jboss-development(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/jboss-development -- Brian Stansberry Lead, AS Clustering JBoss by Red Hat _______________________________________________ jboss-development mailing list jboss-development(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-development

It's JGroups. Javagroups was the original name of the JGroups project long ago.
