Porting JDBCRealm from tomcat to OC4J

I'm porting a servlet from Tomcat 5.5 to OC4J 10.1.3.1.

In Tomcat we set up a JDBCRealm for authentication and authorization. This was configured via the $TOMCAT_HOME/conf/server.xml.

Is there a similar mechanism in OC4J? Where do I start looking for it? How do I define it?

From stackoverflow

• Yes, there is a similar mechanism in OC4J. It is the DBTableOraDataSourceLoginModule which is a login module that ships with OC4J.
