MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Content-Disposition: inline X-Google-Sender-Auth: 069ff88503b3e13e X-Virus-Checked: Checked by ClamAV on apache.org I am trying to use embedded derby for testing but I am finding it much slower than HSQLDB to start and run and significantly more annoying since I have to remove the actual files between test runs to ensure my database is clean. Is there a way to force derby to not create any files and therefore operate more like something like HSQLDB? -AZ -- Aaron Zeckoski (aaronz@vt.edu) Senior Research Engineer - CARET - Cambridge University [http://bugs.sakaiproject.org/confluence/display/~aaronz/] Sakai Fellow - [http://aaronz-sakai.blogspot.com/]
