Running Tomcat on port 80 under non root?

[Alec Bau]

On Solaris 2.7 we need Tomcat process to use port 80 but to run under id other
than root. Is there a trick or conf option to do this, i.e. grab port 80 under
root and then set user id to something else? Or the only way is to modify source
and to call setuid via JNI after socket is bound?

Thanks,
