Hi PeterJ, Tks for your advice and URL The link http://www.alexandriasc.com/software/JavaService/index.html providing Javaservice is not working anymore. Any alternative? Tks. anonymous wrote : I run on Fedora Core 5, so I cannot comment directly on Ubuntu though I recall seeing some forum posts from Ubuntu users. . The JVM that comes with Linux distros is usually insufficient to run JBoss (or any app server), so you should also get a JDK from http://java.sun.com. A 1.4.2 JDK is fine, but if you plan to do any EJB3 work, you should get the 1.5 JDK. I also have FC5_64/32 bit boxes. On FC5_64 box running; $ yum search "Java 5 LVM" and $ yum search jboss They can't be found. Any repo carry with them. Or I have to download them from respective website? anonymous wrote : 3) No, but most people developing for JBoss use Eclipse or NetBeans. There is a JBoss-specific Eclipse plug-in at http://labs.jboss.com/portal/jbosside/?prjlist=false.If I understand your advice correctly. Eclipse is the platform for developing JBoss not for my application. Others noted with tks. B.R. satimis View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3964202#...
