Tomcat correct way to create instances !?

Hello all,

I'm wondering what is the correct way to create several instances with the tomcat RPM.

Reading the file /etc/sysconfig/tomcat, one understand he should create a new sysconfig file with the customs parameters and then symlink the init.s script to start the new instances.

The scripts then should create the needed directory in /usr/share/${NAME}

But, It never really worked here. and I always ended tweaking around the directory, the symlinks, the permissions, etc.

It seems, I'm not the only one, as searching the Internet, one can find a lot of comment, blogs, etc telling either not to use the RPM or to tweak it their way.

Even OpenSuSE did patch the tomcat initscript so the multiinstance isn't possible anymore.

So does anyone knows how it is supposed to be configured ?

thanks.
