Looking for a RAD Java Scala Linked Data Framework

Hi,

over the next couple of weeks we are developing a small Linked Data
application to be used internally.

The base requirements are pretty generic, e.g. it needs to be able to:
1. Add, update or delete instances of the main ontology. 
2. Running the reasoner ( e.g. Pellet) and update the triple store with
any additional inferred statements.
3. Provide a Sparql end point

So I'm interested in any suggestions people may have re Java (or Scala or
Groovy ) Linked Data Frameworks. A framework that could generate the forms
for adding, updating or deleting instances from the ontology itself would
be a bonus.

Being internally based there are a couple of restrictions that we are
working with, e.g. connections to the internet need to be authenticated
with the proxy server, which so far has meant adding  code like the
following 

URLConnection conn = new URL(url).openConnection();
String user = System.getProperty("http.proxyUser");
String password = System.getProperty("http.proxyPassword");

conn.setRequestProperty("Proxy-Authorization","Basic " + new
sun.misc.BASE64Encoder().encode((user + ":" + password).getBytes())); 

when creating connections to external URLs, otherwise there are HTTP 407
Proxy Authentication errors.

A framework already set up to be configured to work behind a proxy server
would be good.

Any suggestions appreciated,

Cheers,

Richard
