The main topic will be Java FX, and then a short overview of the new Java Store Sat, 30 May 2009 03:49:50 GMT Alex Wei http://tech.groups.yahoo.com/group/ajug/message/7294 http://tech.groups.yahoo.com/group/ajug/message/7294 I'm running Tomcat 5.5.23 in embedded mode, not as a Windows native service. But if I switch to use 32-Bit JVM, it works fine... # # An unexpected error has Thu, 28 May 2009 03:04:13 GMT Nick Lothian http://tech.groups.yahoo.com/group/ajug/message/7293 http://tech.groups.yahoo.com/group/ajug/message/7293 All I meant that I hadn't actually used 64 bit windows in production, so talking about it shouldn't have been taken as a recommendation. I didn't mean to start Thu, 28 May 2009 02:19:23 GMT David Bullock http://tech.groups.yahoo.com/group/ajug/message/7292 http://tech.groups.yahoo.com/group/ajug/message/7292 ... For most applications, reboots are not actually needed. For updates, it does reboot itself about once per month ,but that happens in the early hours of Thu, 28 May 2009 01:57:38 GMT Dennis Sosnoski http://tech.groups.yahoo.com/group/ajug/message/7291 http://tech.groups.yahoo.com/group/ajug/message/7291 ... Wow, so 64-bit Vista no longer requires reboots every time you install something? Maybe Windows really is catching up with *nix. - Dennis Thu, 28 May 2009 01:49:59 GMT David Bullock http://tech.groups.yahoo.com/group/ajug/message/7290 http://tech.groups.yahoo.com/group/ajug/message/7290 Aw c'mon you windows-bashers, Vista 64-bit is at least 10 times more stable than 32-bit XP. I have a Vista 64-bit development machine with a comfy 6GB of RAM, Thu, 28 May 2009 01:27:29 GMT Nick Lothian http://tech.groups.yahoo.com/group/ajug/message/7289 http://tech.groups.yahoo.com/group/ajug/message/7289 The mysterious error isn't something like "The specified module could not be found" is it? If so, this might help: Thu, 28 May 2009 00:44:56 GMT John Farrell http://tech.groups.yahoo.com/group/ajug/message/7288 http://tech.groups.yahoo.com/group/ajug/message/7288 Thanks Alex. I estimate the probability of deploying an enterprise application on Vista at 0.0%. If there's anything that would ever make me give up computing, Thu, 28 May 2009 00:39:47 GMT Alex Wei http://tech.groups.yahoo.com/group/ajug/message/7287 http://tech.groups.yahoo.com/group/ajug/message/7287 This probably won't apply to you. But when I run a Java app on 64 bit Java on a Vista 64 bit machine, more often than not, Hotspot VM crashes with a mysterious Thu, 28 May 2009 00:38:46 GMT John Farrell http://tech.groups.yahoo.com/group/ajug/message/7286 http://tech.groups.yahoo.com/group/ajug/message/7286 Thank you all for your replies. I had thought of the performance issue but didn't think too hard about the size of object references doubling.

Yes, the FAIL bus is twice the width on 64bit compared to 32bit. If you have lots of small objects, they will tend to use twice as much real memory as they Wed, 27 May 2009 07:58:19 GMT Steven Shaw http://tech.groups.yahoo.com/group/ajug/message/7284 http://tech.groups.yahoo.com/group/ajug/message/7284 I recall one vendor recommending 32bit JVM on 64bit operating system. The problem can be addition memory usage. Once memory usage increases this can cause Wed, 27 May 2009 06:46:25 GMT Oleg Kiorsak http://tech.groups.yahoo.com/group/ajug/message/7283 http://tech.groups.yahoo.com/group/ajug/message/7283 noticed a funny typo "to ruin Java" was meant to be "to run Java" Wed, 27 May 2009 06:38:30 GMT Oleg Kiorsak http://tech.groups.yahoo.com/group/ajug/message/7282 http://tech.groups.yahoo.com/group/ajug/message/7282 we been running an inhouse UDP Comms Server kind of app combined with a WSes (Axis 1.1) web-app and JSP/Struts web-app - all hosted within Tomcat 5.5 on JDK
