Getting a NullPointerException at Tomcat startup. JDBCRealm configuration
excerpt from server.xml and stack trace below. I've dropped the JDBC driver
JAR into the common\lib directory and set up the realm configuration as
described in the documentation. The driver name and URL are verified because
I successfully use them to configure a datasource in web.xml. Any ideas?
Thanks!
server.xml:
