[Solved]-Stop Eclipse from clearing console-eclipse

if you're running on a server (e.g., tomcat) from within eclipse you can go to the server view, double-click your server, click open launch configuration, then common, then output file. from there you can specify an output destination on your file system or in your eclipse workspace.

this doesn't answer your question exactly, but addresses your subsequent comment re: printing.

i don't think there is a way to do this ... apart from modifying eclipse yourself.

suggestion: run the application outside of eclipse; e.g. at the command prompt.
