Is there any way to start/debug the database system inside the ide?
Absolutely! Derby developers do this routinely. Derby is 100% pure Java, and so any Java debugger can be used to run Derby. When I do this, I build Derby using Ant, with debugging enabled in the compilation, and then I start Derby with my debugger. Tell your debugger to use the main class org.apache.derby.tools.ij, then you can issue ij commands and set breakpoints in the Derby engine using your debugger. thanks, bryan
