Jetty config dependency on Clustering

[Joe Bohn <jo...@earthlink.net>]

Can somebody please help me understand why the Jetty Config has a hard 
dependency on the Clustering config?  It seems a little odd to me that 
we can't build a Jetty assembly that doesn't contain support for clustering.

With Mico-G I was originally able to install the Jetty plugin that I had 
created just fine.  However, since the addition of this clustering 
dependency this no longer works.  If the dependency stays then we need 
to build a plugin for the clustering module.

Whatever ends up as our clustering interface is hopefully going to be  
used by both the web container and openejb.  As such it needs to be  
in only one config, not 2 or more.  If we decide we'll never have a  
connector-only server with no web or ejb support we could perhaps  
include it in j2ee-server.

Thanks for the explanation David.  I didn't realize this only included 
the APIs.

One more question.  Why is it better to create this as its own 
configuration (and for my purposes it's own plugin) rather than just a 
jar that is included with the Jetty (and Tomcat?) configuration as a 
dependency?

I might be coming at this from the wrong angle, but I'm thinking that as 
we expose plugins as building blocks for assemblies (where many plugins 
are basically configs from our build) then some of these items might be 
too granular and confuse our users.  I could see a user thinking that 
they didn't need (or want) clustering and then wondering why it is 
pulled into their image anyway.

Thanks,
Joe

geronimo-clustering just has apis.  Without an api or an  
implementation there isn't going to be any way to have clustering  
support.  Better an api than an implementation.
