Jasper 0.3.0 Can't override JasperViewer

2002-05-14 09:27

Hi,

In 0.2.5 I used to have my own derived class from JasperViewer. I was then able to add my own button to the top area to Save to a PDF file.

Now in version 0.3.0 when I try to override with a constructor as follows:

 

public MPJasperViewer(JasperPrint jasperPrint)

{

super(jasperPrint);

}

 

I get the following exception:

 

MPJasperViewer.java:24: unreported exception dori.jasper.engine.JRException; must be caught or declared to be thrown

 

But I can't put a try...catch around the super() call as Java doesn't allow it. Bit of a catch 22.

 

Thanks

John

Well, I have not downloaded 0.3 yet, but couldn't you just do

 

public MPJasperViewer(JasperPrint jasperPrint) throws JRException

{

super(jasperPrint);

}

 

and then catch it from place where you construct MPJasperViewer ?
