TimeOut for HttpURLConnection

[Amit G Piplani]

Hi,
Can anyone tell me how to set timeout for java.net.HttpURLConnection?

There is a setConnectionTimeout() method in the Java 1.5.0 version of URLConnection (the base class for HttpURLConnection).

If you're stuck using an older Java, you may have to play games with multiple Threads, timers, blah blah blah. Is upgrading your version of Java a possibility?

I can't move to JDK 1.5, how should i go ahead with Threads? but i don't need to use System.Property, since it will set for all URL's

Oops, I take it all back. Try setting the sun.net.client.defaultConnectTimeout and/or sun.net.client.defaultReadTimeout properties. See
this for more information.


For instance, you might start your app like this:

java -Dsun.net.client.defaultConnectTimeout=1500 myClientApp

...to make your client wait only a second and a half for a connection.

Would it be possible to set the property, make the connection request to that one URL, and then set the property back to the default value?

Wouldn't that be nice? You might get away with it in a single-threaded client. But if you're in a multi-threaded environment you'd have to track threads coming in and out of the method that need the lower value.

See the Apache Commons HttpClient package. It has a class compatible with HttpURLConnection that includes timeout.

I tried to find solutions for this that I can use in an EJB container and never did. The spec discourages (forbids) playing with threads.
