Update July 18, 2011: Virgo 3.0.0.M05 upgrades Spring Framework 3.0.5. Steps documented here are no longer necessary.

After upgrading Virgo Web Server to 3.0.0 M03, I wanted to upgrade String Framework’s version from 3.0.0 to 3.0.5. Although this upgrade is on Virgo’s roadmap to 3.0.0, it won’t land for a few more weeks.

Yesterday I ran into a problem with resource loading when using MyFaces. As filed on MyFaces JIRA here, the problem is the result of duplicated resources loaded.

Yesterday I ran into a strange problem, where Hibernate could not successfully create proxy objects using Javassist. My setup had three bundles, a domain bundle with domain classes, a persistence bundle with Hibernate utilities, and a web bundle. When running on the Virgo Web Server, Hibernate would fail to create proxy objects with a strange error.

com.springsource.org.dom4j-1.6.1 is a bundle required by com.springsource.org.hibernate-3.3.2.GA. Satisfying only the required dependency, com.springsource.javax.xml.stream-1.0.1, as specified by SpringSource’s bundle repository, gave me the strange “Unable to resolve due to constraint violation” error message on GlassFish 3.0.1.
