Why am I getting this error?

[burferd]

Using Jasper Reports 1.3.2, Windows XP.

In a JSF web application.

This report used to work fine, but a minor modification was made and now I get an error.

 

 

I have a report named Payroll_new.jasper.

I call

JasperFillManager.fillReport( reportSource, parameters, conn );

with reportSource pointing to the Payroll_new.jasper file.

The parameters and database connection are valid.

 

 

I get an exception from JasperFillManager.fillReport

 

 

Error loading expression class : Payroll_new_1197985302937_990955"
