How can I open a Java console output window for Applet debugging in a browser (windows)?

问题

I have firefox 11 or the windows XP version of IE -

and the browser has jre6 and I have a 6 month old jsdk but the browser doesn't use that for runtime.

nice if log window had history and a scrollbar if there are a lot of prints. I'm using log4j to do the prints.

Thanks.

I hope I understand your question correctly, I think what you are looking for is the 'Java Console'. Here is some info about how to find it and how to enable if it is disabled: http://www.java.com/en/download/help/javaconsole.xml

1. Open the Java Control Panel.
2. (Close the application viewer that opens on top of it.)
3. ..follow the advice at the link shown by Mathias.

The reason for the difference in the opening steps is that the early part of that advice is no longer valid in Windows 7. The steps 1) & 2) outlined above, will get you to the Java Control Panel in XP, Vista & 7.
