hi ,
I am a newbay to J2EE , and I found this forum very helpful.
I have en eclipse Helios , Jboss application server and MYSQL DB ,
under my Jboss I put the
mysql-ds.xml

and the mysql-connector-java-5.1.13-bin.jar under the lib directory :

In my EJB module I have my Book bean :


and a stateless bean


under the META-INF I have the persistence.xml


What I don't understand is .. how exactly should the EntityManager em;
knows to connect the book table .. where should it be define , or where should I configure the JNDI name ?
