Chuck- Thanks so much. I read that doc some time ago, but I couldn't find it again (what a dope). I also read right past the "put it in server/lib" part. I'll try moving the principal class to common and see if that works.

Since you're dealing with principals, the closest model is the JAAS Realm. > If I left the classes in WEB-INF/classes, I received a > ClassNotFoundException on the realm class. > If I put the classes in common/classes, I received a > ClassNotFoundException on RealmBase, which is in catalina.jar. As you should, since the doc explicitly states: "Place your compiled realm in $CATALINA_HOME/server/lib" > Copying catalina.jar to common/lib (a bad practice) Agreed that this is a really, really bad idea. You definitely don't want to muck around with the location of Tomcat's own classes. > Moving just the realm class to server/classes led to > ClassNotFoundException on the principal class. > > Finally, I moved both classes to system/classes, and Tomcat started > successfully. Again from the doc, discussing where to put the Principal classes: "Place the compiled classes on Tomcat's classpath" > However, I then ran into problems between the system classloader and > the application class loader both loading the principal class; the > classes were not the same and led to cast exceptions. This means you placed the same class in two different locations, not just one. Sounds like you failed to remove it from WEB-INF/classes. > 1.

Some addition to Tomcat's environment is unavoidable, since you're extending the capabilities of the server. If you want Tomcat's server classloader to look in additional locations, modify the settings in the conf/catalina.properties file. By the way, unless you're very careful, you will probably need two Principal classes, one for users, another for roles. This is also mentioned in the doc. http://tomcat.apache.org/tomcat-5.5-doc/realm-howto.html http://tomcat.apache.org/tomcat-6.0-doc/realm-howto.html - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
