"Root element is missing". What could it be?

[PauloAndre]

Hi all
I´m a programmer facing (what it seems) a big problem. I have 2 xml documents. I want the document1.xml to make a reference to the document2.xml.
First of all, I declared into the document1.xml the following tag:
<!DOCTYPE ejb-jar PUBLIC &quot; ... &quot; &quot; ... &quot; [
<!ENTITY document2 SYSTEM &quot;document2.xml&quot;> ]>

Then, to call the document2.xml, I did the following

&document2;

The problem is, when I try to execute it, I got the following erros:

&quot;Root element is missing&quot;
or
&quot;Relative URI &quot;document2.xml&quot;; can not be resolved without a document URI:-1:3&quot;

Does anyone have any idea of how to solve this? It would be very appreciated! Thanks!

Paulo
