You can just create a simple web application with a loop that does lots of System.out.printlns.
Normally I discourage System.out and System.err in webapps, but the catalina.out file isn't a true logfile, so if that's what you want to process, you should generate a lot of non-formatted messages to it if you want a proper "real-world" simulation.
