Programmatic access to the Java console log

Question

Is it possible to, and if so how do you get programmatic access to the Java Console Log generated by Java applets?

What I want to do is add a "post bug" button to the applet I am developing. When testers click this button I would like the applet to then package up the contents of the console log as part of a bug report submitted by the applet.

Thanks for any help.

I doubt your exact requirement can be fulfilled, but 'sand-boxed' or 'trusted'? — Andrew Thompson, Oct 21 '11 at 17:49

You can append log messages to a StringBuffer object, and show in Textfield on the click of a button.

Crude (I'd go for an anonymous logger rather than a `StringBuffer`) but effective. +1 – Andrew Thompson Oct 21 '11 at 17:59

Using System.setOut and setErr you can capture output that would otherwise go to the console.
