Opening INTRANET HTML Page

Question

I did a small software to print an HTML Page.
But now I have to make it to work on my Office
in a intranet environment.
For the http://www.homepage.com/ I used plane String.
But now I have to use in a intranet. Someone know
the changes that I have to do to make it work?
I read I small code the uses the class URL and
uses Properties props = System.getProperties(); to set up
proxys data. It is the way? Someone has passed for the
same trouble?

I did the source based on the Java HomePage source.
Take a Look!

As you can see I used String to pass to the Applet the url that I wish to display!. Works!
But now I am changing to the class URL in the new code, so there is a
methods like this:
path = new URL(url);
and ...
          Properties props = System.getProperties();
          props.put("https.proxyHost", "webcache1.eng");
          props.put("https.proxyPort", "8080");
I also find it in the Sun Home Page.
I believe that I can access https://www.homepage.com/ with this lines!
I garantee that you can just access http://www.homepage.com/ with the
code above!!!!!
