title: JPA using variable Schema name in annotations
body: <p>I'm using the Java Persistence API to describe tables from my database that i will manipulate in my code.</p>
  
  <p>However, the <strong>schema</strong> used is not be the same depending on where my project will be installed. So, when I use the annotations, I would like that the SCHEMA field was a variable, but I can't make it:</p>
  
  <pre><code>@Entity
  @Table(name = "TABLE_NAME", schema = schemaVariable, catalog = "")
  </code></pre>
  
  <p>How can I achieve that?
  Is it possible with the <strong>persistence.xml</strong> file?</p>
