I’ve released a new ONess 0.5 version that comes bundled with Tomcat 5.0.30 so it’s ready to run in less than a minute. Uses hsqldb to avoid the need of setting up a database.
Just download from Sourceforge, uncompress, go to the “bin” dir and run startup.bat or startup.sh.
Note that the first time the pages are accesed it may be slow because they get compiled. After that it will run faster.
