How to configure JDBCRealm to obtain its DataSource from JNDI

Question

How do you use a JDBCRealm to handle authenticating and authorizing users in servlets? The only example I can find is to create the DataSource in web.xml

Answer 1

For Shiro to work with permissions with the JDBC realm this parameter is indispensable:

jdbcRealm.permissionsLookupEnabled = true 

I wasted many hours on this because the default for this option is false. In other words, if you don't put this option Shiro always return an empty list of permissions.
