I have the following line of code in my action class's perform method:
request.setAttribute("test10","This is a test");
In the jsp that the action forwards to I have the following line of code:
<% out.println(request.getAttribute( "test10")); %>
I get null as the value. What am I missing here?
thanks,
sriram
