Re: [Idrs-dev] IDRS UML Document

[Tim U. <urb...@us...>]

Hello Marc,

I'm going to start to look at stream lining Init first.  Do you want me 
to look at breaking it out into smaller classes as well?  I also took a 
look at a tutorial on Tomcat's Realms.  There is a Realm interface that 
they implement with JDBCRealm, SecurityRealm, MemoryRealm, ect.  I 
wonder if the easiest thing to do would be to implement Tomcat's Realm 
interface to provide our implementation, that's if we're allowed to do so.  

Anyway, let me know what you think.  

Thanks,
Tim
