Hi there

Code :
<c:forEach var="myList"  items="${requestScope['ListName']}" >
   <option value="<c:out value='${myList.name}'/>"><c:out value="${myList.name}"/></option>
</c:forEach>

Welcome to the ranch ! Please UseCodeTags the next time you post some code. Also, EaseUp. Saying that your request is 'urgent' is not going to help you here.

As for your problem, use the c:forEach tag.

No need to use quotes for your own messages I have removed them.

You'll quickly get used to it

No i am not getting the value

Please post your current code (in a new message). If you use the "var" attribute (set it to something like "details", not "myList", which implies each object is a list) and output myList.firstName it should work. Chances are you're either not retrieving the attribute you think you are, or you're not using the var attribute correctly.

Hi here is my updated code,i made changes but it is not working.

<%
      try {
							
	ViewDetailsForm view = new ViewDetailsForm();
	ArrayList list = (ArrayList) request.getAttribute("ViewObj");							
%>					
	<c:forEach var="details" items="${requestScope['ViewObj']}">
							
	<tr>
		<td><c:out value="${details.getFirstName}" /></td>									
	</tr>							
	</c:forEach>
<%
           } catch (Exception e) {
           }
%>

Thanks

Please UseCodeTags when posting code or configuration. Unformatted code and configuration is unnecessarily difficult to read. You can edit your post by using the button. The link I provide explains how to use them.

Like I said: you're trying to access the list itself, not each item in the list:

<c:out value="${list.getFirstName}" />

See how you're using the word "list" there? The list is the list. Each *item* in the list is "details", because that's what you defined it to be in the c:forEach tag.

I have changed the code, But it is not working

why don't you post your new code?

[santosh mgs]

<c:forEach var="details" items="${requestScope['ViewObj']}">					
<tr>
<td><c:out value="${details.getFirstName}" /></td>
</tr>					
</c:forEach>

See the difference? It's property access, not calling a method. (Update the variable names to whatever you're using now.)

Really, the code tags are easy; "[code]". Just like that. Except for the end tag, which has a slash.
