Looking at your workers.properties file, it feels as if you are running multiple instances of JBoss on your m/c (vertical clustering) | If so, then first make sure that the AJP connector in /all/deploy/jbossweb-tomcat50.sar/server.xml of each server is listening at different port. In you workers.properties it seems as if both the servers are listening on the same port. | | | | <Connector port="8009" address="${jboss.bind.address}" | | emptySessionPath="true" enableLookups="false" redirectPort="8443" | | protocol="AJP/1.3"/> | | | | Second, if you are using windows XP make sure that the windows firewall is disabled. | | Third, it should always be preferred to mention IP address to DNS name of the JBoss server rather than localhost in workers.properties. | | | Hope will help you! | | ~Ashish View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3987487#...
