calling javabean from jsp

package jsp;

import java.util.Date;
import java.text.*;

public class DateFormatBean {
private DateFormat dateFormat;
private Date date;

public DateFormatBean()
{
dateFormat = DateFormat.getInstance();
date = new Date();
}

public String getDate()
{
return dateFormat.format(date);
}
public void setDate(Date date)
{
this.date = date;
}
public void setFormat(String format)
{
this.dateFormat = new SimpleDateFormat(format);
}
}

----------------------
above is java bean script. I created a jar file for this class and kept in class path.

below is JSP
---------------------
<html>
<head><title> a simple example </title></head>
<body style = "font-family:verdana;font-size:10pt;">
<jsp:useBean id="date" class="jsp.DateFormatBean"/>

<h2>hello <%=date.getDate()%>,have a nice day!</h2>
</body>
</html>

----------
when I tried to execute above JSP from tomcat then I got error message as

HTTP Status 500 -

org.apache.jasper.JasperException: Unable to compile class for JSP

It seems JSP file is not able to find the class file. As I kept class file in classpath also it should not give error message.

Please let me know reasons.

I don't have access to the JDK now, but have you tried adding <%@page import="jsp.DateFormatBean"%> to the JSP?
