Also, we use a scheduler called Quartz that requires you to give it a non-transactional (i.e.: 'manual commit') type connection for it to use. My thought so far is that some technique involving firing something up manually using an MBean is what might be a solution. It's tough for me to believe no-one has had the need so far to use their own DataSource implmentation stuff in JBoss. If you so keen to use it in a jboss style which is a JCA way , then you would need to write your own ResourceAdapter and configure the vendor specific DataSource implementation through the conf-property in the connection factory definition xml .
