[SOLVED] Java delay before throwing ConnectException

Java delay before throwing ConnectException

I'm writing some code in Java to dowload stuff from urls and in my configuration some downloads should be handled by a proxy and others without it.

So I wrote this code (it works) to download all URL types but and I'd like to reduce the delay time before a ConnectException is thrown so the code can execute faster.

URL global_url = new URL("http://google.com");
Scanner sc = null;
try { 
    sc = new Scanner(global_url.openStream());
}
catch (ConnectException e) {
    try {
        System.setProperty("http.proxyHost", "my.host");
        System.setProperty("http.proxyPort", "my.port");
        sc = new Scanner(global_url.openStream());
        System.setProperty("http.proxyHost", "");
        System.setProperty("http.proxyPort", "");
    }
    catch (ConnectException exc) {
        //Do stuff
    }
}

Right now it takes approx. 10s before the exception is thrown and I'd like to reduce this time to 2s or 3s max.

Could I get some help? Thanks !

Solution

You can set the timeout like this:

long connectTimeout = 3000;
URL global_url = new URL(urlPath);
URLConnection con = global_url.openConnection();
con.setConnectTimeout(connectTimeout);

where connectTimeout you can set as in milliseconds. As you need 3s timeout so set it as 3000.
