Hi Marco,
You probably need to add an ACL to allow the Restlet java library to
access the Virtuoso Server, as detailed at:

Hi,
I am trying to call the SPARQL end point using Restlet java
libraries. However, when I do so, I get in the response an http
status code of 500 (Internal Server Error) and some HTML:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
<html>
<head>
<title>Error 42000</title>
</head>
<body>
<h3>Error 42000</h3><pre>
HT059: Proxy access to 192.168.1.2:8890 denied due to access control
</pre></body>
</html>
I actually get this error whenever I access any URL managed by the
Virtuoso web server, not just the /sparql/?query..... URLs.
On the other hand, I have no problem getting to the server from any
web browser.
Clearly, my Restlet based client is missing something that the
Virtuoso web server is looking for.
What causes the Virtuoso Server to issue this error and what does
my client need to do to get past it?
Thanks
Marco
