Realms

Example 8-4 shows how to define a JNDI datasource to connect to SQL/MX using the

JDBC Type 2 driver. The JNDI resource can either be configured in server.xml or in

the application-specific context.xml file. For more information on configuring JNDI

resources, see http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html.

For a complete set of attributes that can be used to configure a data source, see

http://commons.apache.org/dbcp/configuration.html.

Example 8-5 shows a sample DataSourceRealm configuration that uses a global

DataSource.

CombinedRealm

The CombinedRealm is an implementation of the Tomcat 6 Realm interface that

authenticates users through one or more sub-Realms.

Example 8-4. Defining a Global JNDI Datasource

<Resource name="jdbc/authority"

auth="Container"

type="javax.sql.DataSource"

driverClassName="com.tandem.sqlmx.SQLMXDriver"

url="jdbc:sqlmx: "

maxActive="20"

maxIdle="10"

maxWait="-1"/>

</GlobalNamingResources>

Example 8-5. Sample DataSourceRealm Configuration

<Realm className="org.apache.catalina.realm.DataSourceRealm"

dataSourceName="jdbc/authority"

userTable="mycatalog.myschema.users"

userNameCol="user_name"

userCredCol="user_pass"

userRoleTable="mycatalog.myschema.userrole"

roleNameCol="role_name"/>

Note. Because the localDataSource attribute is not used in Example 8-5, the Realm

searches the datasource using the jdbc/authority name defined in

GlobalNamingResources.
