Issue while compiling report.

2003-03-07 15:49

Hi Folks,

Seem to have a strange problem at my end. I am trying to compile a report using the JRCompiler.compileReport(jasperDesignHandle) method. All the field in my report are declared as String, but for some strange reason it throws up the following exception

______Exception Ends Here_________________

 

I would like to understand as to what is happening behind the scene. Before you can ask, I have tools.jar in my classpath :-)

 

I am using a data source that I have developed. It is based on the AbstractTableModel and it is very generic. I am on WinNT.

 

Trust this info helps

 

Any help would be highly appriciated.

 

Thanks In Advance,

Shekar

Hi,

 

Check the "class" attribute of your text field expressions.

There it seems you are using Long and Integer

to display String values.

 

I hope this helps.
