Hello All, I have JBoss 4.0.4 GA installed and configuring fine on Solaris and Windows. I got the above error: Caused by: java.sql.SQLException: Already closed. I referred the following link which provided a AOP solution: http://jira.jboss.com/jira/browse/JBAS-3258 I created a SAR/JAR and made the solution deploy on the JBoss. i got the deployed messages too in my Jboss console: 14:07:11,177 INFO [AspectDeployer] Deployed AOP: file:/C:/rajeshchande/installs/opensource/jboss-4.0.4.GA/server/ default/deploy/bug-fix-explode.sar/bug-fix-aop .xml 14:07:11,318 INFO [AspectDeployer] Deployed AOP: file:/C:/ rajeshchande/installs/opensource/jboss-4.0.4.GA/server /default/tmp/deploy/tmp28680bug-fix.sar-contents/bug-fix-aop.xml , but I continue to get the same error as before: Caused by: java.sql.SQLException: Already closed The application is throwing error because of this. Can anyone help? Its getting a bit critical. Thanks & Regards, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3973541#...
