I have an old Spring MVC project which I used to run with Eclipse on JBoss and using JPA 2.0 with (I believe) a PostgreSQL 9.1 DB. Also using Maven as dependencies resolver.
I managed to get the project back from an HDD crash but I couldn't get it to run properly using Eclipse/Tomcat so I thought I might use the opportunity to start using STS (Spring Tool Suite) and get a clean project and just re-insert the code where it belongs.
Sadly, I'm stuck at the very beginning... I created a Spring MVC project with Maven support, but can't set up the JPA 2.0 part.
I went to Project > Properties > Project Facets, checked JPA and clicked on the freshly appeared link "Further configuration required...".
This brought me to the JPA Facet configuration panel where I can choose from two platforms "Generic 2.1" and "EclipseLink 2.5.x". I could only find some noSQL and Oracle support for EclipseLink so I thought I would go for Generic 2.1 (does that mean it's JPA 2.1 ?).
Now I can choose a JPA implementation "User Library" or "Disable Library Configuration". I tried importing the .jar defined by this maven dependency:
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.1.Final</version>
</dependency>
But it just tells me "The class 'javax.persistence.Convert' is required to be in the selected libraries".
Maybe Hibernate's version of JPA isn't "Generic 2.1" compliant ? I've seen a few times "you need to download Hibernate tools" but that didn't change anything.
Also, when I try to create a connection using PostgreSQL, I don't have any driver to choose from and if I want to add one, the only one I'm allowed to add is a jdbc-postgres-8.x driver.
