Turning on tomcat's access log in jboss

Edit the file:

jboss-4.0.3\server\default\deploy\jbossweb-tomcat55.sar\server.xml

Uncomment the following section:

<!-- Access logger -->
<valve classname="org.apache.catalina.valves.FastCommonAccessLogValve" prefix="localhost_access_log." suffix=".log" pattern="common" directory="${jboss.server.home.dir}/log" resolvehosts="false">
</valve>

The log file would be created:

jboss-4.0.3\server\all\log\localhost_access_log.2006-02-21.log

Starting up 2 jboss nodes on windows with HASingleton

One can start up 2 jboss nodes on the same machine, if you have any problems startin up your nodes then define them explicitly in tcp mode rather than udp mode (HASingleton prooved to be working much better in tcp mode):

Setting up tcp mode instead of udp mode is very easy:

a. in cluster-service.xml
b. bind_addr="localhost"
c. start_port="7800" on first node and 7801 on the other node
d. initial_hosts="localhost[7800],localhost[7801]" on one node and on the other initial_hosts="localhost[7801],localhost[7800]"
