[jdom-interest] Bug in JDOM or not ????????

[Sanjeev Verma [CONTRACTOR]]

Hi Chris:

The reason for the exception you are seeing is not because your xml is invalid, 
because as you rightly said, it is! The error message says: "Reference to 
undefined entity "®"". What it means is that the DTD of this XML does not 
define this entity.

This is XML parser behavior. Everytime it comes accross a entity, it will try to 
resolve it as defined by the DTD. So, if the XML does not have a DOCTYPE 
declaration at the beginning, or the DTD declared in the DOCTYTPE does not 
define this entity, then this problem will occur. Check to see which is the 
reason for failure in your case.

Regards

Sanjeev
