Peter,
I struggled with several timeouts for a little while, you can set a
connection timeout using:
httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(connectTimeout);
A socket timeout using:
getMethod.getParams().setSoTimeout(socketTimeout); //getMethod is an
http method created earlier, but the example is pretty self explanatory
Another problem I had with timeouts was during a transfer when the
connection was established and the socket timeout did not apply due to
slow transfer or something, and that gets a little annoying if you want
to create something like a user timeout. I had to create a scheduled
task, kind of like a unix sigalarm handler.
private class TimeoutTimer extends TimerTask {
private HttpMethod method=null;
private int timeout=0;
public void setTimeout( int i ) { timeout = i; }
public int getTimeout() { return timeout; }
public void setMethod( Object i ) { this.method = (HttpMethod)
i; }
public HttpMethod getMethod() { return method; }
public void run() {
logger.error("Fetch URL Timed Out Due to user timeout of "+
(int) timeout/1000 +" seconds being reached");
method.abort();
method=null;
}
}
then schedule it (using java 1.5) and execute your method:
TimeoutTimer timeoutTimer = new TimeoutTimer();
Timer timer = new Timer();
//then create your method as usual.....
timeoutTimer.setMethod(getMethod);
timeoutTimer.setTimeout(userTimeout);
timer.schedule(timeoutTimer, userTimeout);
httpClient.executeMethod(getMethod);
timer.cancel();
I hope that helps.
Does anyone know if any future plans exist to extend the standard method
interface to include a user defined timeout to a method execution? i'm
not entirely sure this feature would be in keeping with the HttpMethod
contract, not knowing how other people are using it.
Thanks, John
