[jira] Commented: (GERONIMO-5021) Allow gbean classes to be loaded from another plugin

["David Jencks (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GERONIMO-5021?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12798244#action_12798244 ] 

David Jencks commented on GERONIMO-5021:
----------------------------------------

rev 897346 implements this and uses it in jetty and jasper. The welcome-jetty-server seems to work OK. This doesn't use runtime jsp compilation but does use a precompiled jsp.

> currently when we deploy an ee app we add import-packages for the geronimo bits needed for the gbeans to run it to the resulting plugin's manifest.mf.  This has a couple of undesirable features:
> 1. the geronimo classes are visible to the app.
> 2. we can't use our deployment for things like osgi rfc 66 which start with a bundle that happens to be a WAB and doesn't allow for modifying the manifest to add our import-packages.  We could possibly work around this by using fragment bundles associated with the WAB but this still alters the visibility environment of the app.
> Proposed solution is to add a field 
> private Artifact classSource
> to GBeanData that a module builder can set to indicate to GBeanInstance where the class should be loaded from.  This is quite gbean-centric in that we are using geronimo artifacts to identify a geronimo plugin rather than something more osgi-friendly.  However, since we're using gbeans, this might not be such a big problem.
