Can I set different locale in JBoss machine from Oracle database machine? For example, I run both JBoss and Oracle database under windows, and I set locale of JBoss machine as CA.English (Canadian English); but Oracle database as US.English. I did some try, however, in some scenarios, I got some problems on numeric format (like . or , as decimal point). So, my question is: must JBoss machine set the same locale as database machine (in my case, US.English)? Any configuration changes should I do if I run JBoss in a different locale machine?
