downloading HTML source code in an online applet

I'm working on an applet that involves downloading and parsing through html source code. To do this, I'm using the java.net.Socket class. My applet works fine in an Applet Viewer, but throws an exception (I'm not sure which one) when I try to upload it to a webpage.

I've been reading various forums, and it sounds like you have to make your applet trusted by signing it, but I was wondering if there was any other way of accomplishing this. For example, is there any way to accomplish this without using sockets?
