(There is one strange thing - you don't need to be logged as the user you want to connect to DB, you can use e.g. -Duser.name=osuser when execute java code and this also works, so if you know username than you can connect to DB - it looks like security issue).   And yes I've tried to remove  <user-name/> and <password/> from ...ds.xml in JBoss but this doesn't work. I've also tried to add -Duser.name=... parameter to run.bat in JBoss bin but this doesn't change anything. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/520235#520235
