Not to nitpick, but there is a 3rd way. (Not that I'd really recommend it for someone who
can't get the Tomcat GUI to work for them.)

Use regedit to export the Procrun branch of the registry tree to a "registry merge file",
which you can then modify with notepad.exe.  Then all you have to do is double-click the merge
file to have the setting replace those in the registry.

Remember, I don't recommend this unless you really know what you're doing.  It's by far easier
to use the GUI.
