Exception when filling report

2002-12-16 05:24

Hi,

 

I'm getting a ClassCastException (see below), when trying to fill a report. The reports' compilation is ok.

 

If I try to fill a non-database filled report, everything is ok, even in complex design reports.

 

The version of JasperReports lib I'm using is 0.4.4.

 

Thanks for any help!

 

Error message:

 

java.lang.ClassCastException: Assigning instance of class java.lang.Class to field dori.jasper.engine.base.JRBaseTextField#pattern

Hi,

 

Are you sure iReport is already compatible with

JasperReports 0.4.4?

 

Thank you,

Teodor

Sorry,

 

I assumed you use iReport because I saw

IReportCompiler in the stack trace.

 

Make sure you are compiling the reports using

the same version as when you fill them.

 

I hope this helps.

Teodor,

 

you're right, I'm using IReport.

 

When I had the error message for the first time, I was using the lib that came with IReport, so I decided to switch to 0.4.4.

 

As the design of the report that I'm trying to fill is extremely simple (just a database field), I didn't suspect about IReport design mistakes.

 

Thanks for your help,

Raffael

Hi,

 

To isolate the problem, maybe you should

try to compile and fill the reports outside iReport.

 

The error has something to do with the formatting

pattern you have used fo one of your text fields.

 

I hope this helps.

Teodor,

 

the problem was jsdk 1.2. I just updated to 1.3 and it started working.

 

Thanks,

Raffael
