Hi,

I'm looking into a problem with commons-beanutils and commons-logging
related to "undeploying" or "reloading" components running within
j2ee-like frameworks.

This article:
  http://www.onjava.com/pub/a/onjava/2001/06/26/ejb.html
states that 
<quote>
Startup and shutdown classes (admittedly, a propriety extension provided
by vendors, but generally unilaterally supplied by all vendors)
</quote>

Can any j2ee/websphere/bea/geronimo/etc experts out there confirm that
there is no *standard* way for an application deployed within a j2ee
framework to register a callback that will be invoked when the component
is undeployed, but that these systems *do* provide non-standard ways to
do this?

I'm thinking that rather than the current rather complex and only
partial solution based on WeakHashMap or similar taken by projects such
as commons-beanutils and commons-logging (SVN head) this issue, it might
be better to hook into the container's shutdown hooks instead.

Thanks,

Simon
