Good thing we have the mailing list [1]. The solution was to run `ant` to build Tomcat, and then open Run/Debug Configurations, and set set the Working Directory to the output directory of ant, e.g. `output/build` in default settings. > Personally, I haven't tried running Tomcat in an IDE for years.

The way I have it set up I can make a change and restart my debugging session immediately.

It looks like the docBase is set to the source dir for the webapps. That probably means there aren't any compiled classes present hence you get the CNFE. At a guess, I'd try adding the WEB-INF/classes directories as additional source locations. That should result in the resulting class files being included in the common class loader.
