Using a Java Program to execute JavaScript from a website

Question

Okay, let me try and explain as good as I can. I have a program now, that searched through all files and folders in Unix (Solaris machine) and gets the list of files in the bin and sbin folders.
Well, I want to find the version of each of these files from the bin and sbin folders and not all of them have the -v, -V or -version feature (or any others there may be). But, I found this page:
http://sunsolve.sun.com/pub-cgi/fileFingerprints.pl
where if you go to the page I can find an md5 number, place it in the box and click submit to find versions, if available.
My thing is, as I find the number from my java program, I want to be able to open this page, insert in the box (or maybe even call the javascript function) and then submit to get the version numbers. That would mean I could need to get back info from the javascript function.
I hope that explains what I need and hope that someone can help me.
I have found information on the JSObject, but not sure what that means exactly so if someone can explain this:
JSObject win = JSObject.getWindow(this);
JSObject doc = (JSObject) win.getMember("document");
JSObject loc = (JSObject) doc.getMember("location");
String s = (String) loc.getMember("href"); // document.location.href
win.call("f", null);     
it would be greatly appreciated. But, this may not even be what I need. I see that the win.call is where I would call the function needed and I am guessing the null could be where I put the number if that is how the function i need works like that. But, what I dont understand is what "document" is and "location". Also, i the "href" the page I put above? I am just lost on that. Hope someone will understand.
Thank again for the help!

Answer 1

Exactly so. Check out the last item - reading and writing to a URL - writing to a URL.
Pulling out the form code from that page:
<FORM METHOD="POST"  ENCTYPE="application/x-www-form-urlencoded">
<TEXTAREA NAME="md5list" ROWS=16 COLS=66 MAXLENGTH="33792"></TEXTAREA>
<BR><INPUT TYPE="submit" NAME="submit" VALUE="submit">
<INPUT TYPE="reset" VALUE="reset">
</FORM>You should end up with something like this (copying and pasting from the example):
URL url = new URL("http://http://sunsolve.sun.com/pub-cgi/fileFingerprints.pl");
String sNumbers = "put your serial nos in this string"
URLConnection connection = url.openConnection();
connection.setDoOutput(true);
PrintWriter out = new PrintWriter(connection.getOutputStream());
out.println("md5list=" + sNumbers);
out.close();
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null){
  // read in the HTML page result for later parsing?
in.close();
