Re: [jdf-dev] [fedora-java] Chosing implementations for EE APIs and finalizing guidelines

Basically Fedora maintainers want to have a single version of everything.

So this would mean that (Fedora) AS 7 would build & run with those API artifacts.

Unless a pom explicitly specifies a jboss-spec artifact and Marek decides to package those in the regular fashion.

So having a dependency on javax.enterprise:cdi-api would place you in the shit house. ;-)

Much like the JBoss specs, these RPM packages will become the official "headers" for any Java packages that rely on Java EE APIs.

I'd hate to see that effort passed up in Fedora. Take note of the criteria that Stanislav mentions below to determine which artifact to use to create the API package for each spec (# of dependencies is a primary concern). If you'd like to participate in this decision, feel free to submit feedback in the #fedora-java IRC channel or the fedora-devel(a)lists.fedoraproject.org list (or contact your local representative, i.e., Marek or Carlo, hehehe). >>>> >>>> If you need some motivation as to why you want to get involved, here's a preview of some of the artifacts that have been selected.
