Async REST web services calls

[Гулько Александр]

Sebastian,

Try Apache HttpComponents library for HTTP requests:
http://hc.apache.org/. Your code will be much more simpler.

Furthermore it has async client (
http://hc.apache.org/httpcomponents-asyncclient-dev/index.html) and the
example (
http://hc.apache.org/httpcomponents-asyncclient-dev/httpasyncclient/examples/org/apache/http/examples/nio/client/AsyncClientHttpExchangeFutureCallback.java)
special for your case.

Regards,
Alexander
