Re: [jetty-dev] Option for Setting Context Params in Deployer Descriptors
No problem, happy to help. We're starting to use Jetty more heavily so having good documentation benefits us as well as everyone else. :)
If there are additional questions you have let me know. I can do some more digging in the code and stuff.

Hi Chad, Hi Greg,

I will get to the web app deployment piece within the next few days.

Thanks for your careful work researching and writing it.

Regards,
Shirley

    Chad,

    awesome - thanks for the contribution!
    I've CC'd shirley (our tech writer), so she can process what you
    have done.

    with regards to something that is in both context and webapps, the
    WebAppProvider has

    http://download.eclipse.org/jetty/stable-7/apidocs/org/eclipse/jetty/deploy/providers/WebAppProvider.html#setContextXmlDir%28java.lang.String%29

    this scans for matching context xml files (by name) and does not
    deploy the webapp if one is found.

    cheers
