I have just bought the Oreilly Enterprise JavaBeans 4th edition. And there they don't speak about the JAWS.xml. I even readed the JBOSS 4.0 starters guide, and there they also didn't mentioned the JAWS.xml.
I setted up the JBoss 4.0, to work with CMP beans, I created one bean, but my bean still works with the Hypersonic DB, and I can't figure out why my bean doesn't work with my MySQL database. I have posted my code to the java.sun.com forum.
