Tomcat specific resource configuration is performed using the following Tomcat specific resource configuration is entered in it has a zero-arguments constructor, and has property setters that configuration details that the client application must be aware of (it is the same as for the DataSourceRealm): Next, modify $CATALINA_BASE/conf/server.xml to create the element as part of the JDBC driver. getObjectInstance() method is called, with the following Tomcat includes a UserDatabaseFactory that Unpackage the distribution and place mail.jar into $CATALINA_HOME/lib so "JSP Examples" link.
