BTW: you figured it out but I should have clarified in the original question.  When you pass parameters to a JSP using the param tag .. the include file must retrieve them using request.getParameter("paramname");

Now AFAIK, you don't need the toString() b/c all request PARAMETERS are strings.

are you getting compilation errors or is the code just not working right?

the code compiles, the parameter data is not returned (except for the getData)

  <% String pageType = "type1"; %>

  <jsp:include page="incpage.jsp?getData=junk" flush="true">
    <jsp: param name="pageName" value="name1" />
    <jsp: param name="pageType" value="<%=pageType%>" />

Here is incpage.jsp:

   // check for null, if null convert to ""
   String pageType = (request.getParameter("pageType")==null) ? "" : request.getParameter("pageType").toString();
   String pageName = (request.getParameter("pageName")==null) ? "" : request.getParameter("pageName").toString();
   String getData  = (request.getParameter("getData")==null)  ? "" : request.getParameter("getData").toString();

  Page Name: <%=pageName%><BR>
  Page Type: <%=pageType%><BR>
  Get Data:  <%=getData%><BR>

Here is the output:

  Page Name: <BR>
  Page Type: <BR>
  Get Data:  junk<BR>

Thanks for the extra help.

to simplify, I did this with the same results:

   String pageType = request.getParameter("pageType");
   String pageName = request.getParameter("pageName");
   String getData  = request.getParameter("getData");

<jsp: param name="pageName" value="name1" />

Please remove the space between "<jsp:" and "param name .../>"

Then should be

<jsp:param name="pageName" value="name1"/>
