The console window in eclipse has rather short ‘history’ and surprisingly the tomcat log file doesn’t appear anywhere on the hardrive when you run your application directly from eclipse. (Or it is situated in some mysterious place) It took me some time to find an option allowing to capture the content of console window to a given file.
The solution :
Run menu – > Run configurations… – ><your tomcat server > – > common – > Standard input and output
Tick the option ‘file’ and type path to your log file.
