Orbeon Forms 4.3不使用MySQL

I have installed JBoss 7.1.1, Orbeon Forms 4.3 and Mysql 5.6. My goal is to use MySQL for Orbeon. I have setup and tested the MySQL connection successfully in JBoss but from what I can tell, Orbeon is still not using MySQL. I created the MySQL tables as outlined in the "Oracle, MySQL, and DB2 Persistence Layers" document but the are not being populated with data when I create and fill out forms. I assume, then, that it is still using the build in eXist database.I have installed JBoss 7.1.1, Orbeon Forms 4.3
