Subject Re: RFC 66 and Geronimo
Date Thu, 08 Oct 2009 13:56:45 GMT
What I meant was that geronimo has full control of artifact deployment
when user is deploying through the geronimo supported deployment
mechanism.  You are right that a bundle can use
BundleContext.install() to install any bundle at any time, but that
doesn't mean it will work or it is supported.   Even with RFC 66, a
bundle that uses BundleContext.install() to install a war would fail
only if they use the webbundle: url schema and use it correctly.

I believe the RFC 66 impl only needs to recognize a WAB is
starting/stopping (not installed) and react to it.

Right, I agree with what you said here, but I am not proposing to do
something with the extender.  I am proposing another url handler which
is invoked when the bundle is installed and before the bundle is
resolved/starting.   I don't think what I am proposing has any
conflict which what RFC 66 describes.
