Detect TimeOut in a HttpURL Connection

I'm trying to invoke a web service using HttpURLConnection and I'm doing the post of SOAP requirement

In general it works, but by problems with the WS it that sometimes freezes
My program freeze in the getResponseCode() method
I would need to detect the time out, and then to return an exception or something like that.

Thanks

In java 1.5 is simple.There are 2 timeout
one is the connection setConnectTimeout(..))
and the other es to read

URLConnection (Java 2 Platform SE 5.0))
If you use 1.4, maybe it would be better if you use Httpclient of Apache
