The XML parser is trying to access the document at http://host/x.dtd (using
the java.net library) and gets a timeout because it isn't accessible.
The fact that you didn't request validation is irrelevant. It's a common,
and erroneous, belief that if you don't request validation then the parser
won't try to read the external DTD. It needs it to expand entity references.
Try either editing the DTD reference out of the file before parsing it, or
using an EntityResolver to satisfy the reference from somewhere else.

> Hi Friends,
