[143]Get request parameter

request.getParameter ( Abc ) ;[1948]Difference between Attribute and Parameter
By Anonymous on 2007/12/24 17:50:01 Rate
"Attributes" and "parameters" are not at all the same thing. Parameters are what are parsed out of the query string, and/or out of the request body in the case of a form POST. Attributes are Java objects attached to particular pages, requests, sessions, or applications and referenced by name. Parameters are passed from client to server in a request; they are text-only. Attributes live only inside the application server, but they can be literally any object.
If you added attributes to the request with request.setAttribute ( ) ,
eg
Public class Test extends HttpServlet {
public void doGet ( HttpServletRequest request, HttpServletResponse response )
throws ServletException, IOException
{
int [ ] myIntArray = new int [ 10 ] ;
for ( int i=0;i < 10;i++ )
{
myIntArray = i;
}
request.setAttribute ( "myArrayName",myArray ) ;
}
}
}
JSP:
< % myIntArray = ( int [ ] ) request.getAttribute ( "myArrayName" ) ;
% >
You need to retrieve them with request.getAttribute ( ) ? Do please recognize that since they are confined to the application server, attributes attached to requests are lost in the process of an HTTP redirect. If by "forward" you meant using a RequestDispatcher or jsp:forward action to deliver the request elsewhere in the same application server, then your attributes will survive the process.
