To easiest way to get up and running with JBossESB 1. Download and unzip the bundle anywhere on your drive. 2. Once unzipped, go into the 'install' directory and edit the deployment.properties file. Really the only thing you may want to change is org.jboss.esb.appserver.home=/jboss-4.0.5.GA, but leaving the default will make your life easier as most example are defaulted to use this directory. 3. in the same 'install' directory run 'ant'. This will default to the 'install' target which unzips JBoss-4.0.5.GA and deploy JBossESB-4.0.GA to it. 4. Now you are ready to startup the appserver. Good luck and enjoy! If you did not get the bundle you can simply set 'org.jboss.esb.appserver.home' to point to your JBossAS, and the ant install target will simply skip the unzipping of the appserver, and deploy JBossESB straight to your appserver.
