Compilation de rapport Jasper
Bonjour,
Je suis en train de tourner autour depuis 1/2 jour et je ne trouve toujours pas.
J'utilise Jasper sous Websphere / Swing pour générer des rapports, mais ça ne fonctionne pas.
Websphere version : 5.1.1
Jasper version : 4.5.0
Voici mon code:

try{
String report = "C:\\Documents and Settings\\My Documents\\report.jrxml";
JasperReport jr = JasperCompileManager.compileReport(report);
JasperPrint jp = JasperFillManager.fillReport(jr,null,con);
JasperViewer.viewReport(jp);
}catch(Exception ex)
{
System.out.println("-------" + ex);
} |
et voici l'erreur:
