servlet-3.0

The javadoc of the javax.servlet.AsyncContext interface says: In the event that an asynchronous operation has timed out, the container must run through these steps: Invoke, at their onTimeout method, all AsyncListener instances registered with the ServletRequest on which the asynchronous operation was initiated. If none of the listeners called complete() or any of the dispatch() methods, perform an error dispatch with a status code equal to HttpServletResponse.SC_INTERNAL_SERVER_ERROR . If no matching error page was found, or the error page did not call complete() or any of the dispatch()

I was trying to implement COMET chat using Async Processing defined in Servlet API 3. It was not working - chat got blocked, so I have created debug servlet to test async part only. This is my doGet method: @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { log.debug("doGet called"); int timeout = 30 + RandomUtils.nextInt(60); String message = RandomStringUtils.randomAlphanumeric(50 + RandomUtils.nextInt(250)); response.setHeader("Access-Control-Allow-Origin", "*"); final AsyncContext context = request.startAsync();

I need dynamic number of columns. Richfaces supplies it with <rich:columns> in richfaces 3.3.3-final but for Richfaces 4 they seem to recommend <c:forEach> . c:forEach I can't get it to work properly.Since I can't depend on the var from the datatable I can't figure out how to feed <c:forEach> with the correct list of columns. (Each row has their own values but headers are the same) Basically the data I want to display is a list with rows of x size, each row has a list of column values with y size. But how can have <c:forEach> tell the backing bean what row it's at so I can feed the correct

I'm running my JSF project launching it with Spring Boot and taking advantage of the whole Spring environment. The configuration is: Mojarra 2.2.8 + Primefaces 5.1 + Spring Boot 1.1.9.

I am trying to use JavaScript SSE from Jersey. I have Following code in my resource. I am hosting on Java7 and Tomcat 7. I dont get any error. But I don't see data either on page.
