Hi!
At the end of RESTController I get:

It is certainly not closing a connection quietly :-)
In URLResponse.java, is it possible that in execute()
servletConnection = this.url.openConnection(); is null?
Responses are like:
if (action.equals("st")) return new
URLResponse("servlet:/thesaurusedit/stdemo",data);
if (action.equals("term")) return new
URLResponse("servlet:/edit/term", data);
}
return new URLResponse("servlet:editor/workspace", data);
Is there an obvious mistake I am making?
Hi,
the only difference I can spot is that your last URL does not include a
leading slash after the protocol: "servlet:editor/workspace" instead of
"servlet:/editor/workspace".
However throwing the NPE in closeQuietly() is a genuine bug IMO.
Does this happen in all cases of your "action" variable or only for a
specific one?
IIRC, URL.openConnection will either return a connection of throw an
exception.
Which would mean that openConnection fails and thus servletConnection
remains null, which is then not handled correctly...
Steven
Thanks,
Jos
