System.out Problem in Java Plug-in

Question

I have the following problem, anyone can help me?
I have an application( Frame ) needed to be embedded in applet. The applecation has a lot of information output to console( by System.out ). When I embeded it into applet, these information will be output to Java Plug-in Console. In the beginning, there is no problem. But when the applet runs enough time, the output will be more and more, and the speed of the applet( in fact, the browser ) runs slower and slower.
I don't want to modify my application at all( it is impossible ). I wonder there is any good suggestion to this problem, I guess, maybe there is an interface to make the Java Plug-in clear its console buffer periodically.
Thanks in advance.

There is a good reason for this.... the console in the java plug-in is essentially a JTextArea... and continually adding text to it via System.out.println or the like will make it slower the longer it runs..... periodically clearing the console would be the only solution without modifying the code......
If you still need all that information you could redirect System.out to your own PrintStream and then instead of writing to the console little by little, you could save the original System.out (using something like:
PrintStream origSysOut=System.out;
) and then later on in your app reset System.out=myPrintStream or something.... then just write the myPrintStream data to origSysOut every now and then or something....
if you want a better example of this I've got a log facility class that I built based on this principal... it's also and easy way to capture stack traces into log files... and since you're just redirecting System.out or err it's easy to turn off the log file to use for debugging.... ok that's enough of a rant :)
