JDBC Oracle 12c connect successful but no data returned

[Layla]

We using Jaspersoft Studio and JasperReports Server 6.1.0 and just upgraded our upgraded from Oracle 11g to Oracle 12c

Made the connection changes to the JDBC (using ojdbc6.jar) and return a successful test connection.

However when we run our reports they ALL return with Document Empty.

Tried creating a report from scratch, by using the wizard and also by just inserting the SQL Statment.  Can see the tables and field, able to "Read Fields".  Place fields in the report.  Run report and once again Document Empty.

Any thoughts?

Thank you,

Layla

Does your report have a report table in it and are you passing parameters to it?

We finally got it working.

Had to change the connection string from 

jdbc:oracle:thin:@localhost:1521:database

to 

jdbc:oracle:thin:@//localhost:1521/database

I don't understand why, but now it is working correctly.
