Not with <jsp:include>, but the recently approved JSP Standard Tag
Library (JSTL) includes <c:import> and <c:catch> actions that can be
combined like this to do what you want:
<c:catch var="error">
<c:import url="${someResource}" />
</c:catch>
<c:if test="${error != null}">
<%-- An exception or 404 resulted from the import --%>
<c:import url="default.jsp" />
</c:if>
For more about JSTL and the Reference Implementation, currently
in Beta, see:
