On tomcat 8.x ,We have been using JDBCRealm to set the connection parameter like jdbc url, user name ,password and with these details we initialize the context and start the server . After upgrading to tomcat 10 i am unable to set the datasource since conncetion url , user name ,password is not present in DatasourceRealm class. I am aware the we should use javx.sql.datasource and some how bind that to Datasource Realm . Programatically i am unable to get the exact code on how to bind. It would be great help if someone help , Thanks in advance.
