I am toying with the idea of writing my own Realm for authentication.
Much of the code and structures that I need are already present in the
web application. Is there any way for the Realm to access Java objects
from the web application? They don't appear to share the same class
loader.
As an alternative is there a mechanism for providing the functionality
of a Realm, but within the web application structure?
You can define the Realm in your context.xml, (which of course you'll
be configuring in the META-INF dir of your web-app, hint hint).
I think this will load classes from your web-app classloader.
N.B. Check out the "localDataSource" attribute, if you're also using a
web-app specific DataSource.

I found that I can define the Realm in the conext.xml in my WEB-INF, but
it is not being located - getting java.lang.ClassNotFoundException when
the web app deploys/starts. I've triple checked that the class files
are there in WEB-INF/classes. I also tried putting in a jar in
WEB-INF/ilb. I'm guessing that the Realm is still being loaded in a
different class loader. I would guess the Realm is loaded in the
"common" class loader, as defined at
http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html.
What is the exact CNFE and is there a stacktrace to go with it?
You've only got the class in one place at any one time I presume?
It's also spelled correctly in the context.xml definition? (you could
post that file here, sanitised for passwords if present).
p
Any other ideas?
