Get Object from reference Id
<p>is it possible to get an object from his reference id?</p>

<p>i get a list of String containing the reference id of an object like:</p>

<blockquote>
  <p>com.test.test.business.model.Gamma@20</p>
</blockquote>

<p>how to get the object from this reference id?</p>

<p>it's only a string and it isn't castable to the object itself</p>
