<p>I've been searching on this subject but unfortunately I haven't found
much, so I hope someone can help me.<br /> I have to perform a
rendering (as shown in the portal when we use View Content) but from
Java and get that result in String.<br /> Could someone give me a hint?</p>
<p>Thank you so much!</p>
