tomcat4 dies when JBDC Realm is configured

[Mubaraka Arif <ma...@alvin.stmarytx.edu>]

hello ,

I have been trying to establish conainer amanaged security , so I tried 
to configure it using JDBC Realm.
Steps what I follwed where :

1. created users table with fields username, password.

2. created roles tables with fields username, rolename.

3. In server.xml I added the JDBC Realm as follows :
    Snippet of server.xml
           <!-- Define the default virtual host -->
       <Host name="localhost" debug="0" appBase="webapps"
             unpackWARs="false" autoDeploy="true">

         <!-- Logger shared by all Contexts related to this virtual 
host. -->
         <Logger className="org.apache.catalina.logger.FileLogger"
                 directory="logs" prefix="localhost_" suffix=".log"
                 timestamp="true"/>

          <Realm classname="org.apache.catalina.realm.JDBCRealm" 
debug="99"
                 driverName="com.informix.jdbc.IfxDriver"
                 connectionURL=" "
                 connectionName=""
                 connectionPassword=""
                 userTable="users"
                 userNameCol="username"
                 userCredCol="password"
                 userRoleTable="roles"
                 roleNameCol="rolename:/>
                <Context path="/onjava" docBase="onjava" debug="0" 
reloadable="true">
         </Context>

                                                                                          
</Host>

     </Engine>

   </Service>


When I start tomcat4 , it starts and dies in about 60sec.

If any of you have encountered such situations , please  provide some 
light to this problem which would be greatly appreciated.
