How to configure my Realm class from context.xml?

Does anybody know how to configure <Realm from .../META-INF/context.xml?

<Realm className="my.realm.JNDIRealm" 
  resourceName="my/RealmFactory"/>

I always get a ClassNotFoundException but the class does exist (under
../WEB-INF.

Erm. Ok. My Realm extends RealmBase so I don't need to worry about such 
things.
But, I guess in the Filter you could cast the request to an 
o.a.catalina.HttpRequest and then call getContext() on it.

PS I've never done the above, nor needed to. Good luck.

Thank you Jon,

That's what I'm also trying but I always get a NPE because
JNDIRealm.containerLog is null.

Do you know how I can figure out the Container from for example a Filter?

In the case I could call realm.setContainer(container) no NPE would happen.

Your Realm implementation needs to sit in the server classloader as the 
Realm interface is only defined there (in catalina.jar).

This is a PITA so when we did this we made the Realm implementation just 
lookup the real implementation via JNDI. That way all the authentication 
logic stayed in the webapp and only a couple of simple wrapper classes 
and interfaces went into the server and common classloaders.

HTH,

Jon
