Re: SPAM-HIGH: Execution Error with Jena

[Rob Vesse <rv...@dotnetrdf.org>]

The code sample you sent is fairly unreadable and does not appear to be
valid Java.  The same goes for your RDF/XML data.

Since this list does not support attachments could you please upload the
code to a hosting service list PasteBin or a GitHub Gist and reply to the
thread with links to the code and data.

Thanks,

Rob
