Thank all of you,
I am getting problem in getting value from requestScope in el statement,I tried one example.
index.jsp:
<form name="frm" action="sample.jsp">
Enter your name <input type="text" name="name">
<input type="submit" value="submit">
</form>
sample.jsp:
1 ${param.name}
2 ${paramValues.name[0]}
3 ${pageContext.request.parameterMap.name[0]}
4 <% out.println(request.getParameter("name"));%>
5 ${requestScope.name}
While I am pressing submit button my output In first 4 statement I am getting output and 5 statement is null.As 3 and 4th statement are request i got desired result and 5th is also request but i am getting null ,can any one please explain difference.
