Re: [Webware-devel] Improvement of launch scripts
I think both of these suggestions would be good improvements. The only input I would have would be to also handle the -l or --library option that adds a lib/ directory to the Python path... sys.path.append(os.path.join(appWorkPath, 'lib')) That makes sense, I will take heed of that: The lib directories that have been defined when running MakeAppWorkDir option will be interpreted as relative to the WorkDir unless they were defined with absolute path. -- Christoph --- SF.Net email is sponsored by: Tame your development challenges with Apache's Geronimo App Server.

Re: [Webware-devel] Improvement of launch scripts
On the general subject of a launch script, I've attached a Launch.py
replacement that I've been using. I'm not using it much anymore, since
I'm not using Webware (at least this version of Webware), but it's
worked okay in the past (maybe the attempt to kill existing app servers
is too aggressive, though). I don't have time to integrate it, but here
it is for someone who is interested...
