I hope that its okay to post this. I am a new user to Spring, and I find that just my limited (read initial use) exposure to it has me hooked. I just successfully managed and start the standalone version of JBoss Naming. (outside of JEE) This is awesome. In case any one wants the information here it is:
Spring 2.0-m5
JVM 1.5.0_04
JBoss AS 4.0.3SP1 (for Jars)
NetBeans IDE 5.5Beta (Enterprise)
