title: Create a Jar library for a web application with Netbeans
body: <p>I want to create a JAR library that will be shared among different web projects. <br/>
  This library will contain the @Entity classes for the projects that access to the same database structure. <br/>
  I tried creating "Java class Library". But when I try to add an annotation javax.persistence.Entity i realize that this (annotation) class is not available in my project. Probably because the project is a "standard edition" project. <br/>
  So my questions are: <br/>
  1) the difference between SE and EE is just the libraries loaded or there is some sort of switch triggered somewhere?<br/>
  2) where is, in Netbeans, the corresponding project targeted to the EE platform?<br/></p>
