Purpose

Provide an integrated Hello World application demonstrating JPA persistence using Hibernate and PostgreSQL, in the context of a very simple web application. This demo does not use any real frameworks except for JSTL for a little bit of JSP processing.

This pattern should not be used for all but the simplest possible use cases. However, it's useful to have as a skeleton starting point for a java web application when you don't want to incorporate the complexities of an actual web framework.

Technologies

• Maven
• Hibernate
• JPA annotations
• PostgreSQL
• JSTL
• Servlets
• Log4J via SLF4J
• JUnit
• Hibernate maven plugin

2. Use target/hibernate3/sql/schema.ddl to create your database schema
3. mvn install
4. mvn -e exec:java -Dexec.mainClass=com.force.samples.util.DataLoadUtil (adds some data to the database)
5. mvn tomcat:run
6. Point browser at http://localhost:8080/webapp-jsp-jpa-hibernate/listbooks
