    JGroups UDP Errors starting JBoss AS

    Stephen Wick Newbie

      I am trying to start up a fresh copy of the "all" server for JBoss EAP 4.3 (I know it's redhat but I hope you can help anyway) on my Windows Vista SP2 Laptop.  We run JBoss EAP 4.3 on Redhat Linux servers, but I want to do development on my laptop.  I am also using Eclipse Indigo with the JBoss Tools plug-in (for Eclipse Helios because there isn't a newer version).


      I created a JBoss EAP 4.3 Runtime with the Jboss Tools plugin.  My problem is, when I try to start the server I get the following error message:

      There are other components, like the JMS PostOffice, that use Jgroups, but they use TCP instead of UDP.  TCP is working for some reason.


      I'll also attach the full stack trace and tomcat cluster config.


      I could really use some help.

          The problem was fixed by adding "-server -Djava.net.preferIPv4Stack=true" to the Launch Configuration for the JBoss server. 


          In Eclipse, from the "Servers" view, double-click on the JBoss Server, in my case this was "JBoss EAP 4.3 Runtime Server", then click on the link "Open launch configuration".  Under the "Arguments" tab, add the string "-server -Djava.net.preferIPv4Stack=true" after the memory parameters "-XX:MaxPermSize=..."
