Hi,
I am trying to deploy a web app to Geronimo 2.2-SNAPSHOT. In my
geronimo-web.xml, I have <dep:inverse-classloading/>
But when the web app starts, I got the following Exception, Can
anybody tell me how to solve this problem?
org.apache.geronimo.gbean.InvalidConfigurationException: Getter

javax.management.j2ee.statistics.Stats wanted in classloader:

Looks like you're including java ee spec classes (e.g.
javax.management.j2ee.statistics.Stats) in your application
ClassLoader. You've directed us to load the class from your
application ClassLoader. However, this is causing a conflict with
internal operations.
I usually prefer to avoid <inverse-classloading>, and use
<filter><hidden-classes>, to filter appropriate packages from the
application classloader. E.g.:
<hidden-classes>
<filter>org.jaxen</filter>
<filter>org.springframework</filter>
<filter>META-INF/spring</filter>
<filter>org.apache.cxf</filter>
<filter>org.apache.commons</filter>
</hidden-classes>
You can perform conceptually similar filtering using inverse-
classloading, with <non-overridable-classes>. Try this for starters:
<non-overridable-classes>
<filter>javax</filter>
</non-overridable-classes>
