First you set the URL in various ways using something like
String npacurl = "http://www.npac.syr.edu/index.html";
try {theinputurl=newURL(npacurl);} // URL class is in java.net
catch ( MalformedURLException e) {
  • System.out.println("Bad URL: " + npacurl); }
where you are meant to test to see if URL is legal!
The simplest thing to do now is to see this page with
getAppletContext().showDocument(theinputurl, Frame targetdisplayframe);
Northeast Parallel Architectures Center, Syracuse University, npac@npac.syr.edu
