looking for HttpURLConnection implementation

[Angus Parvis]

Greetings,

Does anyone know a publicy available implementation of the abstract
java.net.HttpURLConnection? I want to do send a "HTML form" via HTTP
POST - maybe you know another implementation, that would come in handy.

Thanks for your help,

Angus

Just how public?
java.net.URL.openConnection()

All you have to do is cast the result of URL#openConnection. Here's
some sample code:

URL url = null;
HttpURLConnection conn = null;
PrintWriter pw = null;

try {
url = new URL( "http://www.usps.gov/cgi-bin/zip4/ctystzip2" );
conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput( true );
pw = new PrintWriter( new OutputStreamWriter(
conn.getOutputStream() ) );
pw.println( "ctystzip=10111" );
pw.close();
// do something with conn.getInputStream()
}
catch( Exception e ) {
...
}

Invoking setDoOutput with an argument of true is what makes it a
POST request, BTW.

Great, I'll try that out. Thanks

Other posts have mentioned the java.net.URL.openConnection(), so I'll
just add that you may also want to check out the open-source HTTP Client
over at the Jakarta Project site. It's really good IMO.

Here's a link:
http://jakarta.apache.org/commons/httpclient/

Let me also warn you that HttpClient implementation of Sun is far from complete
and even somewhat flawed in several areas. In all probability it was written
solely for the purpose of classloading, and not much more (Very similar to the
classes in java.util.zip / jar packages - you have to be very wary of using them
for any other purpose).

The jakarta commons implementation (which another poster suggested) is supposed
to be quite good - and another freeware implementation is available at
http://www.innovation.ch/java/HTTPClient/ (though I wonder if it is still
maintained)
