How can you use Builder Pattern for entities with JPA

I read that it's useful to use builder pattern when you have a class with a lot of parameters. I wonder how you can implement an entity using builder pattern. It would be great if you can provide sample code.

Here is how you can use a builder pattern: link1, link2. Of cause your entities still have to have a default public constructor to be handled properly by ORM. So the builder is only useful when you are going to create your entities by hands somewhere in the code.
