Writing properties to server

Hi,

In my applet im getting some properties from a file on the server, using:

URL url = new URL( getCodebase(), "myfile.property");
URLConnection uc = url.openConnection();
BufferedInputStream bis = new BufferedInputStream( uc.getInputStream());
Properties props = new Properties()
props.load( bis);

How do i save these properties back into the property file, after having altered them ???
I've tried with:

BufferedOutputStream bos = new BufferedOutputStream( uc.getOutputStream());
props.save( bos, "SOME_HEADER");

I get exception; Already connected when trying to save to the file. Is it not possible to both read and write with the same URLConnection ???

Any reply appreciated
