posted Today 04:01 PM Profile for Shalimar Lagcao Email Shalimar Lagcao Send New Private Message Edit/Delete Post Reply With Quote I am new to Jasper reports. I copy a sample code on how to use jasper reports using Netbeans 5.5. Following the procedure and compile the application, and like magic, series of errors appear. Can you help me guys in solving this.

 

Here is the code (very simple and yet have errors):

 

HelloReportWorld.jrxml

----Start after this line----

 

<?xml version="1.0"?>

<!DOCTYPE jasperReport

PUBLIC "-//JasperReports//DTD Report Design//EN"

<jasperReport name="HelloReportWorld">

<band height="20">

<staticText>

<reportElement x="180" y="0" width="200" height="20"/>

<text><![CDATA[Hello World!]]></text>

</staticText>

</band>

use this

Code:

[code]JasperPrint jasperPrint = JasperFillManager.fillReport(context.getRealPath("/reports/WebappReport.jrxml"«»),parameters,con);

Hi,

 

Put the jdt-compile.jar file in the classpath of you application and the problem should go away.

You can find this jar file in the /lib directory of our project distribution package.

 

I hope this helps.

Hi

I am doing my first steps with jasper and strange thing occurs .

even after adding all jar.files to class path.

eclipse can't resolve

 

import net.sf.jasperreports.engine.JREmptyDataSource;

import net.sf.jasperreports.engine.JRException;

import net.sf.jasperreports.engine.JasperFillManager;

 

I am under mandriva 2007 environment and under windos XP import are resolved

 

:blush:

just to give other developers a feedback:

 

teodord's hint to put the jdt-compile.jar file in the classpath of the application made Jasper compile my jrmxl file successfully.

 

thank you very much!

 

leyla.
