ERROR XSDB6: Another instance of Derby may have already booted the database C:\java\Derby\source\trunk\MyDbTest.
There is a lock file which is created and held open when a Derby process has opened the database.
The lock file is released when the JVM is exited or the database is shut down. Since you are getting this error, it is most likely because you still have a test process which is running and which has the database open (perhaps in the Eclipse debugger?) You should be able to look through the various "run" windows in Eclipse and make sure that all your test and debug runs are ended, and then you should be able to start a new run against the database. thanks, bryan
