There was a great question/answer on setting up tomcat (within eclipse) to write log files to disk (see answer by @codesta): Where can I view Tomcat log files in Eclipse?
Through the Edit Launch Configuration Properties wizard in eclipse I can specify which file to write my logs to. However, since it is a single file, it gets overwritten every time the server restarts. I already have access to the current log through the console in eclipse, but is there a way to make this a rolling file so that I can have history?
I have played around with only specifying a directory in the file path, but then no logs are written out.
