Hello No clue no. But you have provided very little information. Could you kindly provide a test case, what is the xml file that you are trying to load? It seems to be a network exception. More info please Thanks

Yes but looks like Sourceforge.net is down

[avikadam]

what i need to do in this case

[benoitx]

Interesting... 1) are you sure this is the problem? 2) Can you change the xml file to point somewhere else? 3) Can it work without the URL for the DTD? Suggestions welcome

Thanks Man for replying so promptly i appreciate it.

Yes, i did confirmed, this is the problem. I tried with local dtd location, it works. Sometime these remote or dtds located at other server makes problem in case they stops supporting or goes down.

[benoitx]

If you could help me by telling me how we could make FlatPack more robust with this issue, that would be very appreciated. I'm not on my computer at the moment, so I could only give you some ideas and guidance. Thanks

Wondering if this is still an issue when we have dropped JDOM in #11
