Converting RichInputDate to specific format

Question

Hi All,
greetings!!!
I am using jdev 11.1.2.1.0
I have two input date component's on my JSPX.
<af:inputDate label="From Date" id="fromDate" binding="#{DepositeLog.dtFrom}" autoSubmit="true" immediate="true">
        <af:convertDateTime pattern="#{resourceBundle['Common.shortDisplayDatePattern']}"/>
</af:inputDate>
<!--  shortDisplayDatePattern is dd-MMM-yyyy : from Resource Bundle -->
<af:inputDate label="To Date" id="toDate" binding="#{DepositeLog.dtTo}"  autoSubmit="true" immediate="true">
        <af:convertDateTime pattern="#{resourceBundle['Common.shortDisplayDatePattern']}"/>
</af:inputDate>In managed bean I am getting these dates as,
        System.out.println(this.getDtFrom().getValue());
        System.out.println(this.getDtTo().getValue());
   //Output of these 2 SOP's is,       
        Fri May 09 10:18:03 IST 2008
        Tue May 01 10:18:03 IST 2012
      Now, I want to convert these dates in the format : 09-May-2008 and 01-May-2012 i.e. in dd-MMM-yyyy format
These new dates should be of String data type.
I don't want to manually fetch the required strings with help of split()
I tried for this,
        this.getDtFrom().getMinValue();
        //which actually returns java.util.Date(), but in my case it returned null.Also,
I tried this,
        SimpleDateFormat sdf = new SimpleDateFormat("dd-mmm-yyyy");//line 1
        String toDate = this.getDtFrom().getValue().toString();//line 2
        System.out.println(sdf.format(toDate));//line 3
   //But it thrown exception:
        "java.lang.IllegalArgumentException: Cannot format given Object as a Date" for line #3Appreciate your help...
Thanks and Regards,
Madhav K.

The following code help you to see the date on ui on given pattern which is defined in <af:convertDateTime>
<af:inputDate label="From Date" id="fromDate" binding="#{DepositeLog.dtFrom}" autoSubmit="true" immediate="true">
<af:convertDateTime pattern="#{resourceBundle['Common.shortDisplayDatePattern']}"/>
</af:inputDate>
Although in backing bean if you are getting the value of date that will not formatted.
BTW you want to format the date on backing bean.Step are
1-Create the object of SimpleDateFormat
2-call format method on newly created object
3-the method will return sting value of the formatted date
Code example is following
    public void dateValueChange(ValueChangeEvent valueChangeEvent) {
        System.out.println(datevalue.getValue());
        SimpleDateFormat sdf=new SimpleDateFormat("dd-MMM-yyyy");
       String date= sdf.format(datevalue.getValue());
       System.out.println("=========="+date);
       }
