Well it would seem that my suspicions are correct, the problem is with the context file, not the web.xml file. If I comment out the Realm in the context file the problem goes away. I suspect that if it having problems loading one of the two classes mentioned, JDBCRealm or the JDBC driver. But I can not tell which. Both are in JARs in the server/lib directory. Any idea how I debug it. David --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
