Hi,
I get the same exception when using the JSP error handler after a
<jsp:include>, eg:
---- index.jsp ----
<%@ page errorPage="error.jsp" %>
<jsp:include page="foo.html" flush="true"/>
<% if (true) throw new RuntimeException("An exception"); %>
-------------------
---- error.jsp ----
<%@ page isErrorPage="true" %>
Error page
------------------
(foo.html can be blank)
Now when I go to index.jsp, I get the following exception:
Error: 500
Location:/index.jsp
Internal Servlet Error:
java.lang.IllegalStateException: Cannot forward as OutputStream or Writer
