there is a problem with tomcat, should I use Jboss or something like that ?

Answer 1

异常告诉您，您必须将version属性从2.0更改为1.0。

Answer 2

Java Persistence Api 2.0 (JPA 2) is a JAVA EE 6 feature.

Apache Tomcat 7 is not a JAVA EE 6 Application Server, is just a lightweight Servlet(3.0)/JSP(2.2) Container.

In order to use (any of the) JAVA EE features (CDI, JPA2, EJB3.1, JSF, etc...), you need a JAVA EE Application Server.

Sticking with Apache Tomcat, you could use Apache TomEE , that is (guess what?) a Tom cat JAVA EE compliant .

Otherwise use one of the other Application Servers out there (Glassfish, Jboss / Wildfly, etc...)
