Ciao a tutti, sto cercando di visualizzare in un'applicazione web fatta con le jsp, un report con jasperreport mediante un'applet però non riesco a capire perchè mi dà errore al momento di caricare il report;in particolare l'errore è:
Error loading object from URL : http://127.0.0.1:10080/GlobalWebModu...Societa.jasper
Non so come fare,potete aiutarmi?
Vi invio il codice applet:
AppletStampa will appear below in a Java enabled browser.
<applet
codebase = "."
code = "AppletStampa.class"
name = "AppletStampa"
width = "400"
height = "300"
align = "middle"
archive = "jasperreports-1.1.0-applet.jar">
<param name=nomeJasper value="http://127.0.0.1:10080/GlobalWebModule/Repots/ReportSocieta.jasper">
</applet>
... e il codice della classe:
