Error compiling report java source file

2005-01-05 16:41



I am trying to compile my first report as a standalone class through Eclipse 3.0 using JDK 1.5 and each time I get the following error message:-

net.sf.jasperreports.engine.JRException: Error compiling report java source file : C:projectsupupaFirst.java


The main method contains the following code:-


JasperDesign jd = JRXmlLoader.load("first.xml");

JasperReport jr = JasperCompileManager.compileReport(jd);

.... Error triggered here .....

Map parameters = new HashMap();


The xml file definition I'm using is an empty definition:-


<?xml version="1.0" encoding="UTF-8"?>


<!DOCTYPE jasperReport PUBLIC "-//JasperReports//DTD Report Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">


<jasperReport name="First" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="30" bottomMargin="30">





However I also tried to compile the sample files that are on the project's website and they still returned the same error.


Any help will be highly appreciated.

<taskdef name="jasperreportcompile" classname="net.sf.jasperreports.ant.JRAntCompileTask">


<fileset dir="${lib.dir}" includes ="jasperreports0.6.0_fat.jar"/>

<!--pathelement location="${jasper.root.dir}/lib/jasperreports-0.5.0.jar"/-->





<target name="jasperreport" depends="init">

<jasperreportcompile destdir="${build.dir}/classes/jasperreports">


<fileset dir="${lib.dir}" includes ="jasperreports0.6.0_fat.jar"/>

<fileset dir="${build.dir}/classes/jasper" includes ="invoice.xml"/>


<src path="${build.dir}/classes/jasper"/>

<exclude name="${build.dir}/classes/jasper/*.*.bak"/>

Thanks BJ for your help I managed to successfully compile the reports using the ant task still using JDK 1.5.


I was then able to view my report through a simple method calling the fillReport and viewReport.


JasperPrint jasperPrint = JasperFillManager.fillReport("./first.jasper", parameters, c);
