I don't use NetBeans, so I am only guessing, but I would suspect that NetBeans is looking for specific files in specific locations to verify that you have provided a proper JBoss home directory. My guess is that one of those files does not exist in 4.2. I also question placing any Java application into Program Files, sooner or later you are going to run into a Java library that simply cannot handle the space in the directory name.
