hi there
im new in jasper-reports. I try to use the engine together with ireport but
i have some problems with it:
i can compile a sample-report without problems useing "ant compile". but if
i open it with ireport do some very little changes ant resave it, its no
possible to compile it anymore. java raises the following error-stack:
[jrc] Compiling 1 report design files.
[jrc] File :
/home/bayo/jasper/jasperreports-3.0.1/demo/samples/shapes/ShapesReport.jrxml
... FAILED.
[jrc] Error compiling report design :

The problem are a few lines. Before my changes it locks like this:
<!DOCTYPE jasperReport PUBLIC "-//JasperReports//DTD Report Design//EN"
"http://jasperreports.sourceforge.net/dtds/jasperreport.dtd";>
<jasperReport name="ShapesReport" pageWidth="595" pageHeight="842"
whenNoDataType="AllSectionsNoDetail" columnWidth="555" leftMargin="20"
rightMargin="20" topMargin="30" bottomMargin="30">
there three lines will be replaces through this one:
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports
http://jasperreports.sourceforge.net/xsd/jasperreport.xsd";
name="ShapesReport" pageWidth="595" pageHeight="842"
whenNoDataType="AllSectionsNoDetail" columnWidth="555" leftMargin="20"
rightMargin="20" topMargin="30" bottomMargin="30">
Then its not possible to compile the report anymore. i know, its a very
basic question bit i cant find a solution for it. I have the same problem if
i create a totally new report, same error stack.
Does someone have some experiences with these withing.
Thanx for you efforts! greetings, dominic
