I got the nukes source from cvs and compiled it. All modules seemed to work with mySQL; however, with hsql, the html module didn't work. When I used hsql, as I clicked on the 'Manage html' link, it went blank. In the jboss console, I saw an SQLException thrown on the sql statement for ejbSelectDirectoriesByPrefix in FileEJB. I looked like the sql statment's not generated correctly.
Also, when I used hypersonic, I still had to include the MySQL driver in the deploy while it shouldn't. I think this relates to the bug above.
Anyone please check these problems any fix them.
