Pull in passed variable to include in page include

If I'm passing a variable from page A.jsp to page B.jsp named incName. How do I take it into page B.jsp and use it as an include for that page? For example

///////////////////////
A.jsp
--------
<a href="b.jsp?incName=myInclude.jsp">Click here</a>
///////////////////////

in page b.jsp I want to take the name of the include (myInclude.jsp) and use it  as an include for that page:
//////////////////////
b.jsp
----------
....
<jsp:include page="includes/<%incName%>" flush="true"/>
.....

/////////////////////

I have also tried something like this:
///////////////////////////////////

<jsp:include page="/includes/header.jsp" flush="true"/>
</div>
<% String incName = request.getParameter("incName"); %>


<% varincludefile ="includes/" + incName; %>
<jsp:include page="<%=varincludefile%>" flush="true">
<br><br>

<jsp:include page="/includes/footer.jsp" flush="true"/>

the page attribute of <jsp:include> does take RTValue. so this should work:

<% varincludefile ="/includes/" + incName; %>
<jsp:include page="<%=varincludefile%>" flush="true">

if not, let me know what error message you are getting.

Ideally speaking there should not be any trick in this one.....
Only precaution you may want to take is to trim the incName value just to shake of any reduntant spaces at the start or at the end....
Do let us know what kind of errors you are getting...

woops, this should get you going:
<% varincludefile ="/includes/" + incName; %>
<jsp:include page="<%=varincludefile%>" flush="true" />

we forgot to close the tag!

do I need this in the top of the page??


<% String incName = request.getParameter("incName"); %>

kennethxuCommented:
the new error is indicating that the problem is in line 28, what is there?

>> <% String incName = request.getParameter("incName"); %>
for sure that you need to get incName declare and populated with right value. if  you still have problem, post the entire page.

Just make some modification :

<jsp:include page="/includes/header.jsp" flush="true"/>
</div>
<% String incName = request.getParameter("incName"); %>
<style>
.subHeadUnsupportedTool     {
    color:          #330066;
    font-family:      verdana, arial, helvetica, sans-serif;
    font-size:      12px;
    font-weight:     bold;
    font-style:     normal;
    margin:          0;
    padding-left:     12px;
    padding-top:     6px;
    padding-bottom:     6px;
    }
.alignpadding     {
    padding-left:     12px;
    padding-top:     8px;
    padding-bottom:     8px;
    }
</style>

<%
  if( incName != null )
  {
      String varincludefile ="includes/" + incName; %>
%>
     <jsp:include page="<%=varincludefile%>" flush="true" />
<%
  }
%>
<br><br>

if you still get errors, please check the 'varincludefile' and 'incName' variable.

Are we sure we are not missing an '/' here while creating varincludefile???????? Just try
String varincludefile ="/includes/" + incName; %> as see if that helps.

kokchoon78 and kuldeep, the error is complie time error so it should be something else instead of the value of vars, which will only cause problem in runtime.

Sorry for the delay.. I went to Las Vegas for the weekend! :)

The include path is correct. It  shouldn't have a leading "/"

kokchoon78 solution worked??? I don't know what the main difference is but it worked!

kennethxuCommented:
I think the problem is actully this line:
<% varincludefile ="includes/" + incName; %>
it should be
<% String varincludefile ="includes/" + incName; %>
