I have used tomcat and I know most of the difficulties about Java and enviroment problems. After reading this tutorial (I am sure people are putting lots of efforts on creating these documentations) I gave it a shot. http://docs.jboss.com/jbportal/v2.6.6/quickstartuser/html_single/ On Windows XP with Java 1.5.0_14 I got several lines of error messages. I do not know how to start as I am not familiar with JBoss Application Server environment. If I fail to run a bundle of JBoss Ap Serv and Portal 2.6.6, I am sure many people failed too. I believe people should try more on making JBoss environment more error-proof because IT Specialists like we are, do not have unlimited time to go through all the JBoss Forums.
