After you have set up a security policy for a report in JReport Designer, you can then publish it to JReport Enterprise Server as normal.
If you now log onto JReport Enterprise Server as different users, you will find that the record-level security settings have been applied to the report. That is, different users will only see the data they are supposed to see.
Note: User defined users and roles may not be recognized by JReport Enterprise Server. If your security policies contain such users/roles, first create these users and roles respectively on JReport Enterprise Server, and then in JReport Designer, synchronize the security information with JReport Enterprise Server by means of importing security information from the sever with the Merge option checked.
