Hi, I can confirm the behaviour Sean's having. I've been seeing it since we upgraded to torque 3.1.1. which uses commons-configuration-1.0.
I think what happens is that when torque initialises it tries to find your datasource through JNDI which you have configured in Torque.properties, and after it also tries to initialise a datasource and bind it to your context which you actually have not configured in your properties file. Previously the commons-configuration package would give a null object when no subconfiguration for the datasource was found in the properties file, but since 1.0 it returns an empty subconfiguration object (which is not null), and that is what 'breaks' the code. The second time you load your app this causes an NameAlreadyBoundException, causing torque initialisation to fail. Ive recompiled torque source with a small patch in the JndiDataSourceFactory and this solves the problem. Recompiling Torque 3.1.1 with and older version of commons-configuration also does the trick. I have also found an elaborate post on the same problem in the archives: http://nagoya.apache.org/eyebrowse/ReadMsg?listName=torque- [EMAIL PROTECTED]&msgId=1440765 Hope this helps, Grtz Wieger On Wed, 2004-12-22 at 18:30 -0800, M.
