Hi to everyone, after search into online resources, I modified the URL in this way "https://[MY IP]/jasperserver-pro/flow.html?j_username=[MY USERNAME]&j_password=[MY PASSWORD]&_flowId=viewReportFlow&reportUnit=/reports/SDRExport&standAlone=true&ParentFolderUri=/reports&Duration=1&RepTimeZome=%2B02%3A00+CET+DST&Start=20140822162700&viewAsDashboardFrame=true&j_acegi_security_check&decorate=no" I found the correct way to pass the "RepTimeZone" value and I've added other suggested parameters, and now the message error changed to "The report is missing default values for at least one mandatory parameter."...
