Error compiling .jrxml file at run time ?

2006-04-27 22:27

Hi,

 

I've started my first JasperReports project, and am using IBM Rational Application Developer (because I'm not a "REAL" programmer).

 

I've got my project working, and added the following JAR's:

commons-beanutils-1.5.jar

commons-collections-2.1.jar

commons-digester-1.7.jar

commons-javaflow-20060411.jar

commons-logging-1.0.2.jar

commons-logging-api-1.0.2.jar

itext-1.3.1.jar

jasperreports-1.2.2.jar

jasperreports-1.2.2-applet.jar

jcommon-1.0.0.jar

jxl.jar

 

I then created a class with the following code:

 

public void execute(String id) throws Exception

{

JasperReport jasperReport;

JasperPrint jasperPrint;

 

try

{

 

JRTextExporter exporter = new JRTextExporter();

 

jasperReport = JasperCompileManager.compileReport("/projects/rsa_PRJ276/orrExtractWeb/WebContent/reports/vwa_test1.jrxml");

jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap(), new JREmptyDataSource());

 

}

 

But when it executes, it always crashes when I try to compile the report ...

 

[28/04/06 15:17:20:453 EST] 110e110e SystemErr R net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:

C:Program FilesIBMRationalSDP6.0Simple_Report_1146201435765_227164.java:4: package net.sf.jasperreports.engine does not exist

import net.sf.jasperreports.engine.*;

 

Using the "J2EE Perspective", I can see the net.sf.jasperreports.engine classes there.

 

It seems lots of other people have posted this question, but I couldnt find any clear answers sorry. Any hints/tips would be great.

I encountered the same error before. You need to set the System property jasper.reports.compile.class.path:

 

System.setProperty("jasper.reports.compile.class.path", "full path to jasperreport jar file");

Hi

 

The simplest way to fix this is to include the jdt-compiler jar (found in the lib directory of the JR distribution) in the classpath.

 

HTH,

Lucian

Thanks! That worked like a charm. I've now made my first jasper report. :)

 

I'm now going to try making a fixed-width flat file with it.

 

Thanks a ton!
