HTTP connection with timeout under Java 1.5

Question

I have developed a simple low-level access to a web service by using java.net.HttpURLConnection.

I need to set a timeout for connection and reading, and this seems to be possible under Java 1.6 and up, but for Java 1.5 I'm completely at a loss.

Is there any replacement for HttpURLConnection that can serve my needs?

My code right now is like this:

        oURL = new URL( this.endpoint );
        httpCon = (HttpURLConnection)oURL.openConnection();

        httpCon.setDoOutput(true);
        httpCon.setDoInput(true);

        httpCon.setConnectTimeout( this.connect_timeout );
        httpCon.setReadTimeout( this.read_timeout );

        httpCon.setRequestMethod("POST");
        httpCon.setRequestProperty("Content-type", "text/xml; charset=utf-8");
        httpCon.setRequestProperty("SOAPAction", this.endpoint+"#"+req.getOperationName());


        reqStream = httpCon.getOutputStream();
        reqStream.write( reqXML.getBytes());

Once I read the response from the output stream, I'm done. However, the implementation of HttpURLConnection under 1.5 seems to lack the two relevant methods.

I think you're not using JDK 1.5, I created a java (1.5) project in eclipse and it allows me to use both methods.

    HttpURLConnection a = (HttpURLConnection)new URL("URL").openConnection();
    a.setConnectTimeout(0);
    a.setReadTimeout(0);

and in the description of the methods it says it's since 1.5

setConnectTimeout

Sets a specified timeout value, in milliseconds, to be used when opening a communications link to the resource referenced by this URLConnection. If the timeout expires before the connection can be established, a java.net.SocketTimeoutException is raised. A timeout of zero is interpreted as an infinite timeout.

Some non-standard implementation of this method may ignore the specified timeout. To see the connect timeout set, please call getConnectTimeout().

Parameters: timeout an int that specifies the connect timeout value in milliseconds Throws: IllegalArgumentException - if the timeout parameter is negative Since: 1.5

setReadTimeout

Sets the read timeout to a specified timeout, in milliseconds. A non-zero value specifies the timeout when reading from Input stream when a connection is established to a resource. If the timeout expires before there is data available for read, a java.net.SocketTimeoutException is raised. A timeout of zero is interpreted as an infinite timeout.

Some non-standard implementation of this method ignores the specified timeout. To see the read timeout set, please call getReadTimeout().

Parameters: timeout an int that specifies the timeout value to be used in milliseconds Throws: IllegalArgumentException - if the timeout parameter is negative Since: 1.5

You can also see the API docs from oracle

http://docs.oracle.com/javase/1.5.0/docs/api/java/net/URLConnection.html#setConnectTimeout(int)

http://docs.oracle.com/javase/1.5.0/docs/api/java/net/HttpURLConnection.html

It says HttpURLConnection inherits from URLConnection and the two methods are public so they are in the HttpURLConnection class.
