Tomcat 6.0.10 DataSourceRealm says "Name jdbc is not bound in this Context"

[Michael Wesner]

I am sure someone has run across this before.  I appreciate any help  
or pointers to other threads about this.

in the logs I get this error:
        un 19, 2007 1:01:24 PM org.apache.catalina.realm.DataSourceRealm open
        SEVERE: Exception performing authentication
	javax.naming.NameNotFoundException: Name jdbc is not bound in this  
Context


What am I doing wrong?



I have a default server.xml.   I configure everything using   META- 
INF/context.xml  and WEB-INF/web.xml


context.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Context path="apppath" docBase="appname" reloadable="true"  
antiJARLocking="true">
        <Resource auth="Container"
                driverClassName="org.gjt.mm.mysql.Driver"
                maxActive="10"
                maxIdle="5"
                name="jdbc/gateway"
                password="apassword"
                type="javax.sql.DataSource"
                url="jdbc:mysql://localhost:3306/gateway?autoReconnect=true"
                username="myusername"/>
<Realm className="org.apache.catalina.realm.DataSourceRealm" debug="99"
           dataSourceName="jdbc/gateway"
           userTable="user"
           userNameCol="Username"
           userCredCol="Password"
           userRoleTable="loginroleview"
           roleNameCol="RoleName"/>
</Context>

web.xml:  (has other things, but here is the auth part)

        <security-constraint>
                <web-resource-collection>
                        <web-resource-name>Secured Area</web-resource-name>

                <auth-constraint>
                        <role-name>Administrator</role-name>
