Subject [jira] Created: (GERONIMO-5744) bundle urls and 3rd party libraries
Date Tue, 28 Dec 2010 06:02:45 GMT
bundle urls and 3rd party libraries

                 Key: GERONIMO-5744
             Project: Geronimo
          Issue Type: Bug
      Security Level: public (Regular issues)
          Components: deployment
    Affects Versions: 3.0-M2
            Reporter: Jarek Gawor

Resource lookup in Geronimo 3.0 returns "bundle" type of urls. However, a lot of Geronimo
code and a number of third party libraries assumes that urls returned by resource lookup return
"jar" or "file" type of urls. Because of this difference a lot of applications might not work
properly on Geronimo 3.0. The Geronimo specific code has mostly been updated to use OSGi-friendly
ways to look for resources. However, we can't expect every 3rd party library to be updated
to be OSGi friendly. So we might need a solution that can return "jar" or "file" urls that
works with most libraries.

One possible solution is to use the BundleResourceClassLoader in the xbean-bundleutils project
(currently used in the OpenJPA plugin). That solution could be enhanced with Equinox-specific
extension (URLConverter service) that can convert "bundle" urls directly into "jar" or "file"
urls (using the jars in its bundle cache).
