Hi Everybody, ActiveMQ makes extensive use of Derby for storage of it's persistent messages. You have have done a great job with Derby! Thanks for the hard work! One of the things that ActiveMQ supports is running multiple brokers on 1 JVM. In that case we would actually like to run 2 derby instances with different data directories. It seems that currently we have to set the "derby.system.home" to configure where the data files should go. This does not seem to lend itself to supporting multiple derby instances with each with it's own data directory. Is it possible to fully configure derby without using System properties?? -- Regards, Hiram
