In setProperty you have to use name attrute rto identify your bean :
<jsp:setProperty name="time" property="hours" value="17">
instead of <jsp:setProperty id="time" property="hours" value="17">
That's why you have this error :
> org.apache.jasper.JasperException: setProperty: Mandatory attribute name
> missing

Yue Zhang a �crit :
> Try using the same property name as your javabean does, that is:
> <jsp:setProperty id="time" property="Hours" value="17" />,
>
> because both java and JSP are case sensitive.
> By the way, don't forget to use '/' to end setPropertity tag.
