DataSourceRealm
DataSourceRealm is an implementation of NSJSP's Realm interface that uses a user
database accessed using a JNDI named JDBC DataSource. Similar to the
JDBCRealm, the DataSourceRealm requires a set of underlying SQL database tables
to be available.
A DataSourceRealm can be configured in the iTP_server.xml configuration file
nested inside a service or a virtual host. In addition, it can also be configured for a
specific context by nesting the <Realm> element inside the <Context> element in the
context configuration file. Example 3-29 shows an example configuring
DataSourceRealm.
DataSourceRealm Element Attributes
To configure DataSourceRealm, create a <Realm> element and nest it in your
$NSJSP_HOME/conf/iTP_server.xml file or in the <Context> element in the
context configuration file, as in Example 3-20. The following attributes are supported
for DataSourceRealm.
className
The value is org.apache.catalina.realm.DataSourceRealm.
dataSourceName
Specifies a defined JNDI named JDBC DataSource for your database.
Example 3-29. DataSourceRealm
<Realm className="org.apache.catalina.realm.DataSourceRealm"
dataSourceName="jdbc/userDB"
roleNameCol="role_name"
userCredCol="user_pass"
userNameCol="user_name"
userRoleTable="$$DATA00.REALMDB.USERROLE"
userTable="$$DATA00.REALMDB.USERS" />
