RE: ClassCastException, custom Realm, and ClassLoading Repost... this is bugging me.
Help?
We have a custom realm written. Works great until I try to downcast the principal returned from an authentication so that I can call a specific method. Upon investigation (everyone knows this, I know) the error is due to the fact that TC has multiple class loaders and this particular class was loaded from 2 places. I read the class-loader-howto.html that explains the hierarchy. So, I go to put the Jar containing my realm and my subclass of java.security.Principal into the lib directory and I get a ClassNotFound exception for org.apache.catalina.realm.RealmBase
When I put the jar in common/lib I get ClassNotFound exception for com.ensco.nt_authentication.Ensco_NT_Realm
Putting the jar in two places gives the CCE. I have tried putting the jar in all 3 lib directories individually and I get the above chicken-and-egg situation. if I override the entire classpath and specify every jar on the commandline it will work. this is obviously not the best approach. So, then, where do I need to put things to make this work?
