Tudu Lists is focused on the Tomcat application server, which is our only officially supported application server.
However, making Tudu Lists work on JBoss is very easy, and should work just the same (as JBoss is using Tomcat as its servlet container).
Tudu Lists is a JDK 5.0 application : download and install the JDK 5.0 from http://java.sun.com.
Tudu Lists works with JBoss 4.0 : download and install JBoss 4.0 from http://www.jboss.com/.
Copy the tudu-dwr.war file into the JBoss server/deploy/ directory :
cp $TUDU_HOME/tudu.war $JBOSS_HOME/server/deploy
