hi

i want to pass an Enumeration from a servlet to an Jsp through an Attribute, but am facing problems in the getAttribute() method even after casting it into an Enumeration
Here is the code....

Servlet code....
Enumeration En = getServletConfig().getInitParameterNames();
request.setAttribute("enu",En);

JSP code....
Enumeration en = (Enumeration)request.getAttribute("enu");
while(en.hasMoreElements()){
String i = (String)en.nextElement();
}

Please guide me what is wrong in the code since its giving classCastException

1. How did you redirect from your servlet to your JSP ?
2. Which package did you import in your jsp ? (java.util.* ?)
