servlet filter and the Configuration

[MG...@escholar.com]

Okay,

        So I think I've made some progress since my question yesterday.  I 
have a bean in Spring that is a ConfigurationFactory.  It returns a 
singleton and the dataSource can be obtained from that.  Now I just need 
to get that configuration loaded on web startup.  I guess I need to write 
a filter because all the filters (the one in cayenne and the click 
project) create a new shared configuration on init with ServletUtil.  I 
guess I want to override those init()'s and get a reference to my bean and 
call initialize() on it directly.  Is that correct?  When I do this will 
that Configuration become the shared configuration?  If not how do I make 
it the shared configuration? Any other gotchas I should be aware of when 
doing this by hand?

Thanks.
-Mike

Sounds about right.

It does as long as either of the following is called either in your  
Filter or your Spring factory for Configuration:

Configuration.initializeSharedConfiguration(conf);

or

ServletUtil.initializeSharedConfiguration(context);
