Copying this entity (not entity bean) from: http://java.sun.com/developer/technicalArticles/J2EE/intro_ee5/



I am just wondering that they are putting annotations (id, many to one etc) on getter methods. Why???

Isn't it better and cleaner to put these kind of annotations on variable (instead of methods)?

What's say?

Thanks.

You can put annotations on either field level OR method level. Most developers prefer annotating getter methods because otherwise method level annotations are overridden.
