> I have a {{Resource}} which has a property named {{releaseMonth}} which is of type {{long}}; then I have a simple {{NumberFormat}}
> {code}
> NumberFormat numberFormat = new DecimalFormat("00");
> {code}
> If I try to execute, in a JSP, the following code, to cast the {{releaseMonth}} property to the primitive {{long.class}}:
> {code}
> <%= numberFormat.format(properties.get("releaseMonth", long.class)) %>
> {code}
> It throws an exception:
> {code}
> Caused by: java.lang.IllegalArgumentException: Cannot format given
> Object as a Number
> at java.text.DecimalFormat.format(DecimalFormat.java:486)

> Looks like that
