Re: request parameter question ...

[Mufaddal Khumri]

Hi ,

I tried using

request.setAttribute("name", "newName");

try
{
	String path = "/SomeJSP.jsp"
	 
getServletConfig().getServletContext().getRequestDispatcher(path).forwar 
d(request, response);
}
catch(Exception ex)
{
	ex.printStackTrace();
}

When i do a request.getParameter in my JSP page .. it returns a blank  
sting "" . This is the reason I thought maybe request.setAttribute is  
not the method I should be using. Do you have any clues as to why this  
might be happening ?

Thanks

that is what request.setAttribute is there for.

you can also look at JSP forward, that allows you to set parameters,  
not sure how this translates to a servlet

Subject: request parameter question ...
Hi ,

In my servlet I have the following code:

String str = request.getParameter("name");

if(str.equals("xyz") == true)
{
        str = "ChangedName";
        request.setParameter("name", str);   //
<------------------------- how
do i do this ??? There is no method as request.setParameter()
}
try
{
        String path = "/SomeJSP.jsp"
        
getServletConfig().getServletContext().getRequestDispatcher(pa
th).forwar
d(request, response);
}
catch(Exception ex)
{
        ex.printStackTrace();
}
one way to do it would be to append the parameter and its
changed value
to the path:
String path = "/SomeJSP.jsp?name=str";
But is there some method like setParameter to do what I want to do ?

Thanks.
