--------------------------------------------
Not been activity on this one for sometime. Does anyone have any comments re:
relevance of this with regards to the way Nutch is moving? I think it is out
with the scope of the 1.4 release.
> Allow Plugins to be Loaded from Jar File(s)

> Key: NUTCH-609

> Project: Nutch
> Issue Type: Improvement
> Affects Versions: 1.0.0
> Environment: All
> Reporter: Dennis Kubes

> Currently plugins cannot be loaded from a jar file. Plugins must be unzipped
> in one or more directories specified by the plugin.folders config. I have
> been thinking about an extension to PluginRepository or PluginManifestParser
> (or both) that would allow plugins to packaged into multiple independent jar
> files and placed on the classpath. The system would search the classpath for
> resources with the correct folder name and would load any plugins in those
> jars.
> This functionality would be very useful in making the nutch core more
> flexible in terms of packaging. It would also help with web applications
> where we don't want to have a plugins directory included in the webapp.
> Thoughts so far are unzipping those plugin jars into a common temp directory
> before loading. Another option is using something like commons vfs to
> interact with the jar files. VFS essential uses a disk based temporary cache
> for jar files, so it is pretty much the same solution. What are everyone
> else's thoughts on this?
