A sada probam sledece i dobijam isto!!!


import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.JasperReport;

public class FirstReportCompile
{
public static void main(String[] args) throws JRException
{
//jasperReport = JasperCompileManager.compileReport("reports/rep1.jrxml");

JasperCompileManager.compileReportToFile("reports/rep1.jrxml","reports/rep1.jasper");

//jasperPrint = JasperFillManager.fillReport(
// jasperReport, new HashMap(), new JREmptyDataSource());
//JasperExportManager.exportReportToPdfFile(jasperPrint, "reports/rep1.pdf");
}
}

Dakle, JasperCompileManager.compileReportToFile(), ne prolazi!!!
Nije mi jasno u cemu je stvar!?

ocigledno nisi dodao sve jar-ove koji su potrebni jasper reports-u.

Mislim da ovo treba dodati za osnovni prikaz o izvestaju:

* commons-beanutils-1.5.jar
* commons-collections-2.1.jar
* commons-digester-1.7.jar
* commons-logging-1.0.2.jar
* commons-javaflow-20060411.jar

naravno 1.5 moze da bude i 2.04. u zavisnosti od verzije jasperreport-a

Pozdrav


commons-beanutils-1.7.jar
commons-collections-2.1.jar
commons-digester-1.7.jar
commons-logging-1.0.2.jar
commons-logging-api-1.0.2.jar

se nalaze u jdk-u i jre-u, koristim jdk 1.5, a probao sam da dodam u jdk-ov lib sve iz ./jasperreports-2.0.3/lib ali ista stvar.

Inace org/apache/log4j/ConsoleAppender je iz log4j jar-a a imam

org.apache.log4j_1.2.13.v200706111418.jar u d:\eclipse\plugins\
ant-apache-log4j.jar u D:\eclipse\plugins\org.apache.ant_1.7.0.v200706080842\lib
log4j.properties u D:\eclipse\plugins\org.apache.axis_1.4.0.v200706191647\lib

probacu da dodam njih na classpath pa da vidimo!?

Proveri da li su verzije iste, mozda imas stariju verziju log4j, imao sam slican problem da smo imali neku strariju verziju iText-a u projektu, pa je to pravilo probleme jer pdf export nije radio. U principu dodaj sve sto im je u lib direktorijumu pa probaj onda.

Izludece me ovaj Jasper :/ Nasao sam log4j-1.2.15.jar i dodao ga u build path

Sada na sledeci kod:

package test;

import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperCompileManager;

public class JasperReportsCompileTest {

public static void main(String[] args) throws JRException {
JasperCompileManager.compileReportToFile("reports/new_report.jrxml","reports/new_report.jasper");
}

}

Dobijam:

Zivo me zanima otkud mu E:\workspace\JasperTest\Unnamed_1200322489214_796291.java !!!
Odakle ga dodade u javac -classpath ?!?!?!

:) Ti znaci jos uvek ne znas koliko je sam Jasper jako mocan alat, on zapravo svaki report konvertuje u java fajl, i nakon toga kompajlira java fajl i dobijes sam report.

E sada prvo i osnovno pitanje dalje, dali si setovao JAVA_HOME environment promenljivu i da li si dodao JAVA_HOME/bin u PATH ?

Upravo sam malo googlao i shvatio kako jasper radi :) Upravo to ocemu pricas.

Interesantno!

Sada sve radi i mogu slobodno da se prepustim carima "report-iranja"

Hvala svima koji su mi pomogli!

Pozz

E sada zamisli samo da u sam report ubacujes svoje metode koje vracaju String ili neki drugi podatak koji mora da se racuna na neki nacin :), tada stvari zaista postaju vrlo interesantne. Mada kada su grafofi u pitanju, trebace ti i znanje JFreeCharta ako hoces da nad grafovima napravis customizacije do kraja, kakve recimo mozes da napravis u Crystal Report-u

vrlo uskoro ce se pojaviti i nova verzija iReports-a, dostupan je i plagin za netbeans

Hvala sto ispisali ovu temu.
Poceo sam da koristim Jasper pre par nedelja, i odmah sam naleteo na iste pocetnicke probleme:
ovakve:
Exception in thread "main" java.lang.NoClassDefFoundError: itd....
a pogoto ovakve:
Izludece me ovaj Jasper :/


Vec sam dovoljno izludeo da sam hteo da odustanem i da predjem na kristal reports ili nesto trece
a onda sam guglovao "Exception in thread "main" java.lang.NoClassDefFoundError: ..."
i iskocila mi je ova tema.

Jeste da je proslo dve godine, ali za mene je bilo vrlo aktuelno
hvala hvala hvala.

Pa za to i sluze forumi!!! Nisu oni samo za experte vec i za pocetnike.

Znas kako narod kaze " Ko nema u glavi ima na googlavi" :))))

Pozdrav i tebi i Univerexportu :) (vidim da pises sa tog domena)
