Jasper and time fields

2006-01-19 20:54

I keep a few time fields in a PostgreSQL database, stored in the hh:mm:ss format.


When the user wants to construct a report, they use my ReportBuilder interface. A JasperDesign object is created and filled by the ReportBuilder interpreter, compiled on-the-fly, and the report is displayed using JRViewer.


For any fields representing a time, I initially chose to specify the value-class for the expression of the hosting textfield in the report to be java.util.Date.


However, the value shown is always 00:00 (in my preferred display format).


Would someone, please, tell me why that is?


I've since changed the value-class to java.sql.Time, and the output is as I expect (eg. 14:57), albeit that it seems to take a noticeably longer time to display.
