Hi, you can run JBM test suite. check out the latest version of JBM from svn, and take a look at tests/etc/container.xml, set the db to hsqldb.
The build.xml under tests dir contains various test targets.
the 'tests' target is the one we use to cover all jbm tests. However you probably need to remove the cluster tests, as JBM clustering can't work with hsqldb.
And just let you know, JBM 1.4 is in maintenance status. That means only bug fixes or EAP supports. Users can try hornetQ for more new features.
