Problem generating report

[burferd]

I have a canned repport that runs fine in iReport.

 

I am trying to get it to print from my application.

This is the code I am using:

 

 

JasperPrint jp = JasperFillManager.fillReport( reportDir+"Test_Report.jasper", new HashMap(), mySQLConnection);

JasperViewer.viewReport( jp, true );

 

 

I get the following error from the call to JasperFillManager.fillReport()

 

 

"net.sf.jasperreports.engine.JRException: Error loading expression class : Test_Report_1175200944899_991206"

 

 

Can anyone tell me what I am doing wrong and why I get this error??

Can anyone at least tell me if what I am attempting to do in code is correct or if I am doing something wrong??

 

 

I am using JR 1.3.0, J2EE (SDK1.4.2), Sun Application server 8.2.

 

 

Does anyone use JR1.3.0 and should it work in this environment??
