Hi friends, why I have this error?

I use jdk 1.5, jasperreport 1.2.0

Finally, I have one tutorial that explain how use jasper 0.6. In new version there are some deprecated methods. Do you know new tutorial? Thanks

 

public static void main(String[] args) {

try { JasperCompileManager.compileReport("c:/jasper/clienti.jrxml");

} catch (JRException e) {

e.printStackTrace();

}

}
