hello, I have a serious problem. I use JBoss 4.2.3 with JDK6, a database with MySQL and Eclipse to develope my application. My problem is that whenever I restart my JBoss Server all the data in my db are deleted and in addition some charateristics of the attributes of the table are modified (for instance, all the varchar(x) become varchar(255)). Can someone help me??? Thankyou View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4200819#...
