jsp.exists()

[Stan James]

Is there a reliable way to tell if a named JSP exists? I'd like to provide a default page for a missing JSP in one particular spot in an application. This is in a legacy jsp now:

<%
String otherjsp = "path" + somename + ".jsp";
%>
<jsp:include page="<%=otherjsp%>"></jsp:include>

I could see Class.forName() working if I could build up the compiled jsp name, but that sounds pretty yucky.

Perhaps something like:

<c:import url="whatever.jsp" var="theJsp"/>
 
<c:choose>
  <c:when test="${not empty theJsp}">
    ${theJsp}
  </c:when>
  <c:otherwise>
    <c:import url="default.jsp"/>
  </c:otherwise>
</c:choose>

Wow! I have no idea what that is. But it's something I can Google and learn!

Those are examples of the JSTL (JSP Standard Tag Library).

Gotcha. I had never seen the import into a var syntax. Slick. Thanks again!

Very powerful mechanism, that.
