Configured JDBCRealm

[Dalecki, Janusz]

Hi,
I have configured JDBCRealm Tomcat with the following:

<Context>

                <Realm className="org.apache.catalina.realm.JDBCRealm" 
driverName="org.postgresql.Driver" 
connectionURL="jdbc:postgresql://localhost:5432/df_Scheduler?user=postgres&amp;password=admin"
 userTable="users" userNameCol="userName" userCredCol="password" 
userRoleTable="user_roles" roleNameCol="roleName"/>

</Context>
I have a few questions:

1)      How can I get hold of this realm object within my  Java app?

2)      Even if I get the instance of the JDBCRealm - how do I get the list of 
all roles available?
Regards,
Janusz
