Comments on: pomegranate modules http://blog.caucho.com/2009/06/10/pomegranate-modules/ Inside info, thoughts, and opinions from Caucho engineers Tue, 21 May 2013 13:13:17 +0000 http://wordpress.org/?v=2.7.1 hourly 1 By: ankur http://blog.caucho.com/2009/06/10/pomegranate-modules/comment-page-1/#comment-359 ankur Tue, 18 Aug 2009 05:22:39 +0000 http://blog.caucho.com/?p=211#comment-359 Thanks for the info. In my project, I have 1 interface and 2 implementations. Each implementation has its own set of JAR dependencies some of which of may overlap. I am trying to see if I can use Pomegranate as an out-of-the-box solution for this. Any help is highly appreciated. Thanks for the info. In my project, I have 1 interface and 2 implementations.

Look at com.caucho.loader.EnvironmentClassLoader, ArtifactManager, Artifact, ArtifactClassLoader. To alag. I think you're right about the transitivity, but we also need a way to make a link intransitive for certain configurations. I'm hoping for another draft in a day or two.

I'm working on Grizzly Servlet Container and would like to have this great feature there as well. Please keep us posted on OSSing pomegranate. Awesome idea, congrats!

After just a quick pass, I don't think that POMStrap is quite the same. They look like they're inverting the classloader hierarchy, while we're using a classloader cloud model. The difference is that the classloading is not transitive in any direction with our approach. jstrachan: I like the idea. I'll check with the rest of the team to see what they think. Standardization, specs, interoperability... all good stuff. alag: Thanks for the link! After just a quick pass, I don’t think that POMStrap is quite the same.

I wondered if we could spin up a little OSS project somewhere neutral (say google code?) where we could describe the spec of how a pom.xml style dependency mechanism should work with any servlet container - then try get servlet containers to also implement it so it can become a common adopted standard? e.g. we could patch the maven war command to optionally generate the pom.xml in WEB-INF. I was chatting to Greg from Jetty and he's happy to support this model too - so we could get Maven, Resin and Jetty all supporting this simple alternative to OSGi? Incidentally a suggestion from Greg was to consider putting pom.xml in the WEB-INF/lib, so when folks look in the lib dir for dependencies, they see the pom.xml there?
