WebDAO - Java DAO based framework using JPA and Persistence Servlet

Java Persistence Architecture (JPA) is generally used in Java EE applications but can also be used directly in a Java SE program, see this article setting up JPA in a Java SE environment. However, you can get added advantages of running JPA in a web server environment and have your Java SE client programs access that, advantages such as:

  • Better use of JPA connection pool and cache as these are shared amongst the clients
  • Smaller client code without the need for full JPA and JPA implementation libraries
  • Better security as clients don’t need to hold database login information

The problem is how to provide the access and still have pretty much the full functionality that JPA provides, this is where WebDAO comes in.

EclipseLink JPA With H2 Database

EclipseLink JPA With H2 Database explains step by step details of setting / configuring Java Persistence JPA With EclipseLink And H2

How To Configure EclipseLink JPA With H2?

Java Persistence API, is a standard interface which wraps different ORM tools such as  EclipseLink, Hibernate, OpenJPA etc.

ie; you can able to change Hibernate implementation to EclipseLink implementation without changing the code base.

On this standalone JPA Example, we are using Java Persistence With H2 Database

EclipseLink is popular open source ORM (Object Relation Mapping) tool for Java platform, for mapping an entity to a traditional relational like Oracle, MySQL, SQL Server, PostgreSQL, DB2, Derby, Sybase, H2 etc
