I am having hard time understanding JPA. What I want to know is that how to create a java application (JPA) *USING MySQL* , and plain java classes , from scratch. But *NO ENTITY BEANS*. Don't want to use any kind of plugins, (such as toplink as people suggest, no). It shouldn't be tied to glassfish server or any other. I've once programmed using hibernate , but it's been a while and I didn't like modify xml files g by hand. I 'll be using it mainly for creating a web application , of course it will use servlets but no Entity beans. But it will be of much help if you let me know how it can be done through *plain java classes*.
At this moment I am not even concerned with MVC pattern , just would like to know how to make a tiniest application using jpa enough to show me how it is deployed.
p.s :- I know how to code in jpa , I am already using it, with tomcat , mysql .(because it was deployed by somebody else and I know all CRUD operations , all I have to do is to modify those sources) , but I haven't been able to understand how to create such application from scratch. I tried creating a table which stores username, password and other trivial info without any relationships.
