[jdom-interest] Crimson and DTD resolution

[Fred Clewis]

I typically have a lot of xml such the OAG example below that reference
their DTD as:

     <!DOCTYPE SYNC_CUSTOMER_005 SYSTEM "007_sync_customer_005.dtd">

The convention is to access the file in the current directory and not
complicate the portability of the file with references such as
"file:///C:/exactdirectory/...".

Xerces/JDOM did not have a problem with the implicit reference above, but
Crimson/JAXP/JDOM fails to find it and gives:

Root cause: org.xml.sax.SAXParseException: Relative URI
"007_sync_customer_005.dtd"; can not
be resolved without a document URI.

Do I have a misunderstanding of how this should work or is this one of the
costs of the 50% smaller footprint?

thanks,
