Help: JRException: Attribute "class" with val

2002-08-20 15:30

I've been playing around with Jasper for a couple of weeks and really like it. However, whenever I create a report with the designer, I'm unable to later reload it into the designer, I get a "Error at (-1, -1:null)" stop screen.

 

Also, whenever I attempt to compile the generated .xml file, I get the following error (sorry to paste such a long message). I checked all my java.lang. datatypes and they are as requested in the message below.

 

All sample reports work well. Modified xml based reports also work without this problem.

 

Thanx in advance, as I'm sure others have seen and gotten beyond this error in the past. (Long live Jasper!!)

 

Buildfile: build.xml

 

compile:

Hi,

 

Are you sure you don't have a text field in your

XML report design for which you have wrote this:

 

class="dori.jasper.engine.JRDataSource"

 

As you can see from the exception message,

all the possible values for this "class" attribute

are listed.

 

I hope this helps.

Teodor

Teodor, thank you very much. Your suggestion worked. I had put that in the report as a report parameter to see what value it would print.

 

I'm gaining a better understanding of Jasper and exceptions.
