faire fonctionner l'example XMLDataSourceExample [Résolu]

[pcouas]

Bonjour,

je cherche a faire fonctionner l'exmple it.businesslogic.ireport.examples.XMLDataSourceExample
addressbook.jasper
et addressbook.xml
j'en ai trouve sur le Net mais j'ai le message d'erreur
net.sf.jasperreports.engine.JRException: Error loading object from file : c:\prj_java\TestAgarder\jasperxml01\addressbook.jasper
at net.sf.jasperreports.engine.util.JRLoader.loadObject(JRLoader.java:92)
at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:515)
at jasperxml01.Demo3.main(Demo3.java:66)
Caused by: java.io.InvalidClassException: net.sf.jasperreports.engine.base.JRBaseReport; local class incompatible: stream classdesc serialVersionUID = 604, local class serialVersionUID = 10200

je suppose que le fichier .jasper deja serialisé n'est pas compatible avec le Mien, j'ai essayé avec 3 versions de JDK sans succes

Merci d'avance
Philippe

Salut,
Le mieux est de partir du fichier .jrxml et non du .jasper qui est en quelque sorte un "fichier compilé".
Sinon tu as un autre exemple de xmldatasource dans les sources de jasperreports (demo).

Bonjour

J'ai teste sans succes un autre exemple fournis dans les sources XmlDataSourceApp.java avec northwind.xml .
en taskName j'ai force pdf et en fileName c:\\xx.pdf, Mais
a priori il a besoin que mon fichier resultat existe déja ??

Merci d'avance
Philippe

Salut,
Pour la variable fileName tu dois donner le nom du fichier .jrprint.
Appuie-toi sur ce qu'il y a dans le fichier build.xml

Code :

1
2
3
4
5
6
7
8
 
<target name="pdf" description="Generates a PDF version of the report by converting the .jrprint file.">
		<java classname="${class.name}">
			<arg value="pdf"/>
			<arg value="${file.name}.jrprint"/>
			<classpath refid="classpath"/>
		</java>
	</target>

Ou bien exécute directement le build.xml (ANT). Il faut exécuter les cible (target) javac, compile, fill puis enfin pdf.
