Subject Re: Could Not Start The Tomcat Server After Commenting Out Realm in the server.xml For Using JDBCRealm
Date Thu, 09 Oct 2003 16:38:45 GMT
If your realm declaration is:
 > <Realm
 > className="org.apache.catalina.realm.JDBCRealm"
 >           debug="99"
 > driverName="org.gjt.mm.mysql.Driver"
 > connectionURL="jdbc:mysql://localhost/authority"
 > connectionName="test" connectionPassword="test"
 >     userTable="users" userNameCol="user_name"
 >                       userCredCol="user_pass"
 > userRoleTable="user_roles" roleNameCol="role_name" />

Then tomcat will try to connect to localhost for the database "authority" 
with the user id and password being test. (If I read the props above 
correctly). If that connection fails when the Realm is created (which is at 
tomcat startup) - then tomcat will not startup.
