I have a mature project which is using Hibernate as JPA provider. All queries are HQL queries.<br />
Now the requirement is changed for using a composite key on a table that I use frequently. For this, I think I need to use an embedded primary key class thus change all my queries. Can you give me some ideas for coping with this issue with as few modifications as possible?

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
