----------------------------------------
Hi,
I have some problems with this functionality.
$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.RangeCheck(ArrayList.java:547)
at java.util.ArrayList.get(ArrayList.java:322)
at wicket.jmx.Initializer.init(Initializer.java:131)

at wicket.Application.callInitializers(Application.java:837)
at wicket.Application.initializeComponents(Application.java:628)
at wicket.protocol.http.WicketFilter.init(WicketFilter.java:343)
at org.mortbay.jetty.servlet.FilterHolder.doStart(FilterHolder.java:95)
at
org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:39)
...
It looks like
ArrayList<MBeanServer> mbeanServers = (ArrayList<MBeanServer>)MBeanServerFactory
.findMBeanServer(null);
returns empty list.

> http://java.sun.com/j2ee/1.4/docs/api/javax/management/MBeanServerFactory.html#findMBeanServer(java.lang.String)
> <dmhosier> but there would have to be some way to specify the agent ID

> <ivaynberg> a system prop?
> <dmhosier> probably the best bet
> <dmhosier> maybe check if a specified property exists, and use this method to

> <ivaynberg> yeah
