Jasperreports Server 6.2.0 CE - Change the default ZOOM_RATIO parameter in DefaultJasperViewer.jsp

[massimo.musu_1]

In 5.6.0 CE I modified the DefaultJasperViewer.jsp changing the zoom ratio parameter as follow:

exporter.setParameter(JRHtmlExporterParameter.ZOOM_RATIO, new Float(1.35));

I have migrated to Jasperreports server 6.2.0 CE and the same line of code doesn't work. How can I change the default ZOOM RATIO in this version of software?

Thanks.
