- We use hibernate-entitymanager for Hibernate as JPA implementation. hibernate-entitymanager is dependent on hibernate-core this why we don\u2019t have to put hibernate-core in pom.xml explicitly. It\u2019s being pulled into our project through maven transitive dependencies.<\/li>\n
- We also need JDBC driver as dependency for database access. We are using HSQLDB that contains the JDBC driver and a working in memory database.<\/li>\n<\/ul>\n
