Hi Pid,

what you describe is correct and works, I've implemented a Manager
implementation that uses simple attributes until now (for memcached
based session failover, memcached-session-manager:
http://code.google.com/p/memcached-session-manager/ ).

However, now I want to support a complex, nested child element for a
TranscoderStrategy in my case (somehow comparable to the Store element
that is allowed as child element for the PersistentManager), that
supports different attributes depending on the TranscoderStrategy
implementation. It's possible to put all attributes into the Manager
element, but this is not what one would want to do - the related
attributes are spread between the Manager related attributes.

I'm not sure I understand.
Is the requirement an aesthetic thing or does the existing method not actually work for your use case?

In recent versions of Tomcat the Digester complains if it finds unexpected elements during startup. Do you get any error messages in the catalina.out log or on the console, when you implement your preferred structure?

 http://tomcat.apache.org/tomcat-6.0-doc/config/manager.html

If you've extended PersistentManagerBase then you must supply a Store element, maybe your configuration options can be set as attributes on that element.

If you've extended ManagerBase then maybe you can add an object FooBar (with getter & setter) and attributes as needed.

Or have you tried this already?

Hi,

is it somehow possible to have a custom nested element below the Manager
element in server.xml/context.xml? E.g.

<Manager className="org.app.MyManager">
    <FooBar foo="bar"/>
</Manager>

where the MyManager class has a property fooBar?

If the MyManager class has a field called fooBar, with matching getter
and setter, then (my guess, based on how Valves work, is that) you can
probably set it by doing this:

<Manager className="org.app.MyManager" fooBar="somevalue">

</Manager>

AFAICS the ContextRuleSet defines what's possible in the Context element
without any hook - so it seems that there's no possibility to achieve
this.

If someone could tell me that I'm wrong with this asumption I would be
happy! :-)

Thanx&&   cheers,
Martin
