I have in my project a Ms Access database which worked fine before, now after formatting my computer I've run my project and It worked but when I opened the database with MsAccess 2007 and closed it. It won't get updated with the Java project.
I still have copies of database which wasn't opened with MsAccess and it works fine if I use it. so the problem is opening the database with MS Access - it kind of lock it read-only ( that's what the Jackcess says )
