Java SE (Java Platform, Standard Edition)

Hello,

I wrote the following code that puts some text inside a JEditorPane. A part of the text is normal text, and another part of it is hyperlinks. I've tried to use stylesheets, as you can see in the code, to show hyperlinks in a different way, meaning underlining them, changing the color, etc... But I haven't been successful. Do you have any ideas? Am I missing something here? or doing it the wrong way?
Please help out.
Thanks.
