Custom Realm

[Michael Dockery <do...@yahoo.com>]

I need to override a single method in a standard tomcat6 realm for a particular 
webApp/context.    


The method:   RealmBase.getPrincipal(X509Certificate usercert)


Q1) Should I create a new custom realm (..subClass of RealmBase) which is 
based-on/copied-from the original/standard tomcat realm?   


Q2) what all classes will I need in my new custom realm?  (...only  
MyCustomRealm class itself? )

Q3) Should I reference my new realm  via my webapp's META-INF/context.xml file?

Q4) Should I put my realm class(es) in a jar inside the tomcat6/lib directory?


...I am new to tweaking realm's, so appreciate the feedback.

You can, but wouldn't it be simpler to subclass the realm whose behavior is already closest to what you want?

A realm is usually just one class.

Yes.

That's where it must go, and only there.
