Question

I have a java applet trying to pass some GET data to a php file in the same directory as my applet. When I start a url connection to the file.php and pass the data, I don’t get anything, however when I append the full URL in front of the PHP file, it works.

Here’s what I have:

URL sp = new URL ("file.php?data1=" + data1 + "&data2=" + data2 + "&data3=" + data3);
BufferedReader in  = new BufferedReader(new InputStreamReader(sp.openStream()));

But, the data only gets passed if i add my full http://www.website.com/ url in front of file.php

EDIT:
It works now, with a URL test = new URL(getCodeBase(), “form.php”);

Answer 1

Given documents located:
– http://www.website.com/docs/applet.html (document base)
– http://www.website.com/forms/form.php (target form)

server (http://www.website.com/)

• docs
  • applet.html
• forms
  • form.php

An URL to form.php can be created using either of..

// relative URL
URL relative = new URL(getDocumentBase(), "../forms/form.php");
// absolute URL
URL absolute = new URL(getDocumentBase(), "/forms/form.php");
