Welcome to Data Access Layer for Java (DAL4j) a set of command line tools and framework used to reverse engineer a MySQL or SQLServer database schema into a set of JPA Entity Beans. DAL4j can be useful for scenarios where there is an existing database schema but a technology other that JPA is used to interact with the database. DAL4j can provide an easy way to migrate your code base from other technologies such as JDBC or Hibernate to JPA. The beans generated can be 1 or two types: Simple or Framework. Simple beans are standard pojo classes managed by your application using JPA semantics. Framework generated pojos use the DAL4j framework DAO generic to simplify CRUD operations. DAL4j provides optional hooks to allow you to integrate encryption/decryption of data field used when data is encrypted in the database. Last, DAL4j provides a set of Generic classes that can be used to simplify creation of J2E Session Beans which perform CRUD operations using generated Entities
