Dynamic Date Picker Date Range

[KiranKumar Chandrasekhar]

Dear All JSF Experts & Users,
I've a requirement where in DatePicker component should show only the current month starting from 1st till today.I tried to use

<hx:validateDateTimeRange minimum="#{startDate}" maximum="#{yesterday}" />

startDate is being retrieved from Database and set to the servlet context like getServletContext().setAttribute("startDate",firstDt);//2007/05/01

But i'm getting Unparsable Exception:-------------------------------------
javax.faces.convert.ConverterException: Unparseable date: "#{startDate}"
Unparseable date: "#{startDate}"
Unparseable date: "#{startDate}"
