NotSerializableException ?
Hi,
When I shut down my tomcat server with my cocoon application (schaman)
inside, I get a mysterious NotSerializableException which seems to be
linked to both Spring and Flow (see
org.mozilla.javascript.NativeJavaObject.writeExternal(NativeJavaObject.java:993))
:

Any idea of what can be the cause of that ?
Thx in advance.

Servlet event listeners [1] are probably what you're looking for. But
i'm sure there is a "spring" way of doing this as well.

And your guess is good. I think my problem comes from a ServiceLocator
singleton I use to access my Spring services. It's not a class of my
own, it's automatically generated by AndroMDA and it has a shutdown()
method which releases resources. It should release that
NotSerializable transaction manager but the problem is how can I
automatically call this method after each request or at least just
before my application is shut down ?

Not sure but here's my best guess:
Upon container shutdown, Spring (or maybe the container itself) tries to
be a good citizen and serialize the session to disk. Now there are some
components/classes in flowscript that are not serializable, hence the
session serialization fails and you get this stacktrace.
