I am having the same problem. I am using JSP 1.2 which works ok with Tomcat 4.x, but when I try to deploy to a recent version of JBoss or Tomcat 5 I get that error.
I do an include of a header file (with no parameters) like this: <jsp:include page="header.jsp" flush="true"/> Then in the header.jsp file have a simple JSTL statement which does this: <c:choose> <c:when test="${not empty SessionData}"> Logged in. </c:when> <c:otherwise> Not logged in. </c:otherwise> </c:choose> I get the error and the page does not display. If I remove the JSTL from header.jsp it works ok. Where did you put the dummy jsp:param? I tried putting inside <jsp:include> tags, but that didn't help.
