DataSource Realms

[Lisa Modglin]

Is anyone out there using DataSource Realms in Tomcat 5? I could use some help setting it up.

I understand Tomcat's instructions for database layout, how to add the realm element to the server.xml and how to set up the realm element in the server.xml file.

I don't understand how to configure a JNDI named JDBC DataSource. There is a link to instructions, but even after reading, they make no sense to me.

There are 3 pieces to setting up the Realm. Using the server.xml file as an example:
1- Resource tag, this declares the name and type of the resource.

<Resource name="UserDatabase" auth="Container"
          type="org.apache.catalina.UserDatabase"
          description="User database that can be updated and saved">
</Resource>

2- ResourceParams tag, this defines what Tomcat should do to initialize the Resource

    <ResourceParams name="UserDatabase">
      <parameter>
        <name>factory</name>
        <value>org.apache.catalina.users.MemoryUserDatabaseFactory</value>
      </parameter>
      <parameter>
        <name>pathname</name>
        <value>conf/tomcat-users.xml</value>
      </parameter>
    </ResourceParams>

3- Realm tag, this attaches to the Resource named in the resourceName attribute.

<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
       debug="0" resourceName="UserDatabase"/>
