tomcat4 dies when JBDC Realm is configured

[Mubaraka Arif]

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.
