I'm attempting my first usage of JSP. Previously, I've used JServeSSI to include
servlet output into a .jhtml page.
I'm in the process of migrating to Tomcat and JServeSSI will not work in the servlet
2.2 environment.
I'm attempting to do a <jsp:include page="/servlet/MyServlet" flush="true" /> to
include my servlet's output in my page.
It seems to run the servlet; however, I'm getting the following error:
Included servlet error: 500: Internal Servlet Error:
java.lang.IllegalStateException: Writer is already being used for this request
