The Update Center has been a feature of NetBeans for what seems like forever for all tools built on top of the NetBeans platform: NetBeans IDE, Java Studio Creator, Java Studio Enterprise, Sun Studio, etc…
Following that thinking that an IDE could always be updated online, Creator lived for more than a year without requiring a reinstall (with even a JDK update in the process). That sounds nice, but when you do a fresh install of the tool, you have to go through the update process of downloading over 100megs :-(
This was until now and Update 9 of Creator 2004Q2.
If you are new to Java Studio Creator, you really want to try Creator 2 Early Access 2.
