Query epoch date in SQL Server does not work from Jaspersoft Server

[heila.mckinley]

I have a report which takes as an input parameter a date using the date picker.  The date is stored as an Epoch date in SQL Server.

When I run the report in Jaspersoft Studio it works.  The relevant bit of query looks like this:  and cr.open_date + 7200 >= datediff(ss, '19700101', '$P!{Open Date from}' )

I publish the report to Jaspersoft Server and when I try to run it I get error below.  What am I doing wrong?  

The server has encountered an error. Please excuse the inconvenience.

Error Message

I would use the java.util.Date.getTime() method to get the epoch, and compare the epoch field using that parameter.

Create a second parameter (name it OpenDateFromEpoch) that performs that translation, and use the second parameter in the query.

Something like :

and cr.open_date  >= $P{OpenDateFromEpoch}'
