Question

I’m trying to develop a Java application with Maven while using Hibernate with a PostgreSQL database for persistence. I don’t understand how I’m supposed to connect the PostgreSQL drivers to my application. I get that you add dependencies in Maven’s pom.xml file, which finds jars from a remote repository, but what about other jars?

Answer 1

PostgreSQL drivers jars are included in Central Repository of Maven:

• List of included versions of PostgreSQL drivers.

For PostgreSQL up to 9.1, use:

<dependency>
    <groupId>postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>VERSION</version>
</dependency>

or for 9.2+

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>VERSION</version>
</dependency>
