Some times in , h:outputText with dataTable or without , java.util.Date showing wrong, means one date before the actual date is showing.
We can solve this problem using Converter.
One example :

DateConverter.java

package com.converter;
import java.text.SimpleDateFormat;
import java.util.Date;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.ConverterException;
/**
* This class is is used to convert a date to dd-MMM-yyyy format
*
*/
public class DateConverter implements Converter {
public String getAsString(FacesContext context, UIComponent c, Object object)
throws ConverterException {
if(object!=null && !object.toString().equals(“”)){
final Date date = (Date) object;
String dt=null;
if(date!=null){
SimpleDateFormat formatter=new SimpleDateFormat(“dd-MMM-yyyy”);
dt=formatter.format(date);
return dt;
}}
return null;
}
public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2)
throws ConverterException {
return null;
}
}

In faces-config.xml

dateConvert
com.converter.DateConverter

In your jsp page

<HTML>
<HEAD>
<SCRIPT language=Javascript>
<!–
function isNumberKey(evt)
{
var unicode=e.charCode? e.charCode : e.keyCode
if (unicode!=8){
if (unicode<48||unicode>57)
return false;}

return true;
}
//–>
</SCRIPT>
</HEAD>
<BODY>
<INPUT id=”txtChar” onkeypress=”return isNumberKey(event)” type=”text” name=”txtChar”>
</BODY>
</HTML>
Here this above coding shows to use Javascript to allow only numbers to be entered in a textbox. This is useful for phone numbers, IDs, ZipCodes.

This solution works in both IE and Netscape/Mozilla.

You should be able to put together HTML pages. Java. You should be able to program in Java. This tutorial teaches JSP by progressing from very simple examples to complex examples. For best progress, it is recommended that you type in all the examples presented and get them working. The early examples might seem very simple; please have patience. By actually typing in the examples and getting them to work, you will gain familiarity with the actual practical issues. Also spend some time on the exercises, these are designed to solidify your grasp of the material.
