To enable JGroups on ubuntu system


While you are using jgroups on ubuntu you might get this exception

INFO: JGroups version: 2.6.16.GA

To solve this you need to disable ipv6 on ubuntu. To do that do the following

java -Djava.net.preferIPv4Stack=true -classpath /home/shekhar/JB431/opt/jboss-soa-p-5/jboss-as/lib/concurrent.jar:/home/shekhar/JB431/opt/jboss-soa-p-5/jboss-as/common/lib/commons-logging.jar:/home/shekhar/JB431/opt/jboss-soa-p-5/jboss-as/server/all/lib/jgroups.jar org.jgroups.demos.Draw

    Nice one, this one creeped on me out of no where (wonder why it started all of a sudden) and you had it spot on.

    @newbies
    Only thing needed is really the preferIPv4Stack property

    -Djava.net.preferIPv4Stack=true instead of all the arguments (i.e classpath)
