Hi....
hetParameter() is used to get the values of the field entered in the jsp page....
while getAttribute() is used to get the attribute values set in the request,session or application scopes.For using getAttributes() u will need to set the attribute name & value for a particular request like..


request.setAttribute("COLLECTION_NAME",collection_value);
(Assume collection_value is a ArrayList containing values)

and u can write getAttribute() method on the jsp page to get the attribute value which was set...like

ArrayList myAttribute=request.getAttribute("COLLECTION_NAME");

now u can iterate through ur arraylist values and display on the page using a for loop or logic:iterate tag...


Please notice that getAttribute() returns Object and u need to typecast it as accordingly.


Good luck....
Abhishek

The getParameter() reads a value of the URL or PostData. For example: http://www.jguru.com/blah.jsp?foo=bar. getParameter("foo") will return a String "bar". getAttribute() is to read an object from the request, that has been put there, by for example an Action in Struts, or a Servlet.
