How to deploy JavaEE 7 / JPA 2.1 Dynamic Web Application to IBM Liberty Profile WITHOUT web.xml

Question

I have a Dynamic Web Application that access a DB2 v10 zOS Database.

I wish to use Hibernate 5 as my JPA 2.1 Provider and access my EntityManager via CDI.

I do not want to use the Spring Framework at all; I also do not wish to have a web.xml file.

How can I configure my persistence context and persistence unit WITHOUT using web.xml when deploying my application to WebSphere Application Server Liberty v9 Beta?

Answer 1

The first result on google for "websphere liberty hibernate" gave me the link to a sample app that uses Liberty with Hibernate.

WASdev Liberty + Hibernate sample

Note that the jpaApp.war DOES use a web.xml, but this can easily be avoided by using the proper @WebServlet annotation and changing the persistence.xml to point to a server-defined datasource instead of a component-defined datasource.

@WebServlet(displayName="JPA Servlet", urlPatterns="/JPAServlet")
public class JPAServlet extends HttpServlet {
    // ...
}
