Mantis - Resin
have a Spring-managed MBean that I would like to register with
the resin MBeanServer (the one bound to "java:comp/env/jmx/
MBeanServer" in JNDI). This MBean defines some operations to query
and update some metadata in the database, using Hibernate/JPA.
The MBean registers fine and I can see it in jconsole in the right
place. However, when I tried to invoke an operation, I received an
error. The underlying exception was this:
interface org.hibernate.jdbc.ConnectionWrapper is not visible from
class loader
Loading the Hibernate and Spring jars in the parent classloader
solved the immediate problem:
<resin xmlns="http://caucho.com/ns/resin" [^]
xmlns:resin="http://caucho.com/ns/resin/core"> [^]
<class-loader>
<tree-loader path="lib"/>
<tree-loader path="/path/to/my/webapp/WEB-INF/lib/"/>
</class-loader>
...
However, I'd rather not do this because I want to retain the
ability to deploy multiple webapps with different versions of
dependencies like Spring and Hibernate (mainly so we can deploy a
new version of our webapp and leave the old one untouched so we
have a fallback).
Is there some way to make it so that mbeans are registered and
invoked in the classloader of the webapp that registered them?
