| Product: | [RT] Virgo | Reporter: | Glyn Normington <glyn.normington> |

| Priority: | P3 | CC: | eclipse |
| Version: | unspecified | ||
| Target Milestone: | 3.0.0.M04 | ||
| Hardware: | PC | ||
| OS: | Mac OS X - Carbon (unsup.) | ||

Fixed the class cast exception. Note that the current shell design means that bundles that are powered by the kernel's version of Spring show up as "Spring powered: No" in the OSGi state explorer. This will be taken into account as the RAM and shell are redesigned to cope with the new region design. |
This occurs on recent builds of Virgo web server. Steps to reproduce: 1. Bring up Virgo web server and navigate to the admin console in a browser. 2. In the OSGi state tab, expand the bundle org.eclipse.virgo.kernel.userregionfactory. 3. Expand the Consumed Services tab and then expand the org.eclipse.virgo.kernel.osgi.region.RegionDigraph service. 4. Click on the provider bundle link and the following screen is returned: HTTP Status 500 - type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/state-bundle.jsp at line 54 51: <tr class="sublevel1-odd"> 52: <td>Spring
