java.lang.NoClassDefFoundError: dori/jasper/v

2002-05-29 05:50

Hi I have compiled report with jasperreports0.3.1

I can view report with taskview.bat.

But in my application developed with Jdeveloper

I get Error:

 

java.lang.NoClassDefFoundError: dori/jasper/view/JRPageViewer

 

I put jasperreports0.3.1.jar but I get the error.

I do this:

 

JasperReport jasper = JasperManager.loadReport(jasperFile);

JasperManager.fillReportToFile(jasper,jasperPrint,parameters,conn);

JasperViewer.viewReport(jasperPrint);

With earlier version I don t have problem.

What is the problem?

Hi,

 

In the new version of the library, the class

dori.jasper.view.JRPageViewer is not present

anymore.

The viewers were entirely rewritten.

 

Make sure you don't have an older version of the

library present in the classpath or that you don't

use JRPageViewer in your code.

The equivalent of this would be JRViewer, which is

a component that you can easy integrate in your

application.

 

Thank you,

Teodor

I have last version of jasperreports.jar.

I success to load jasper file compiled with jasperreports0.3.1.jar

If i have older version of jasperreports in my classpath file not be loaded

I success to print report but I cant see preview.

I don t understand why dori/jasper/view/JRPageViewer

is demanded ?

This is happened in Jdeveloper not in development of report

When I build report I don t have problem

In Jdeveloper I use the same jar file.
