eclipse start up error message, how to catch it

Question

I run an eclipse Java Swing application, it works well. but I can see the error messages (red color), before the swing application run. But I can not catch it, because when the application run, inside "console", there are empty. Could anyone tell me, how can i view the error messages which were shown in "console" when I start the java application, but suddenly disappear ( is there a log file for eclipse?). Many thanks in advance.

Answer 1

Right click on the console > Preferences > Console buffer size

If you don't want any limit, uncheck the "Limit console output" checkbox. That's it. You will get all the output written to the console, without getting cleared.
