问题 In my Spring Boot1.2.7/JSF2.2.12/PrimeFaces5.2/Tomcat 8 application I'm trying to implement redirect to login page after AJAX call on a website where /logout has been performed.

问题 I'm developing a web application with eclipse and tomcat 8 in windows, now i want to setup SPDY. I must use apache tomcat 8, this is a constraint project. How can I configure my web application to use SPDY in tomcat 8? 回答1: UPDATE: i wrote a mail to apache users mailing list and they gave me this reply: SPDY support was experimental and for a much older version of SPDY than any current browser supports. Tomcat's SPDY support is not usable in its current form. HTTP/2 support will be available

问题 I am going through the websockets with Spring 4 tutorial here. I have it working where the server responds when client calls. However, my use case is having the server push the messages without client having to call. So I looked up online on ways to do that and came across a few posts that said that I needed to use something called SimpMessagingTemplate . So I changed the code to use the SimpMessagingTemplate . Now I get this exception in the server console: 04-Jun-2016 22:49:24.093 SEVERE

Here is a brief code snip. package com.my.app; import org.glassfish.jersey.server.ResourceConfig; import javax.ws.rs.ApplicationPath; @ApplicationPath("api") public class RestApplication extends ResourceConfig { RestApplication() { packages("com.my.app"); } } And <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>The name of my

问题 I have 2 environments. The first one is a mac where I have installed Tomcat 8 by extracting the .zip file downloaded from Apache's homepage. The second one is a virtual machine on this mac which runs Ubuntu 15.04. I have my web application as a war-file and can deploy that on my mac's Tomcat without any problem. Now, I want to do exactly the same deployment on the Ubuntu. So I copy the Tomcat-folder over to my Ubuntu along with my war-file and try to do the same deployment there. Before I do

问题 I am using Tomcat 8.5 to host a WAR which is used for java REST services. In my rest service, I create a connection and take a multi-part form data file from user, scan it using a scan engine and return the result. At the start, tomcat is running fine and giving a speed of almost 57-58 Mbps but degrades over time (degrades to nearly half in 5-8 min) My setenv.bat file looks like this. "set "JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx5120m -XX:MaxMetaspaceSize=512m -Xincgc -server"" JVM is using

问题 Every tutorial for the upgrade to Spring 5 has tomcat 8.5+ as a requirement but no detailed explanation. The application that I want to upgrade should not run as a standalone application with an embedded webserver, but beeing deployed on a tomcat 6, which we cannot upgrade for several reasons. 回答1: As @procrastinate_later points out, Spring 5 actually requires Servlet 3.1 (and Tomcat 8.5.x). Spring 5 has initially was expected to have Servlet 3.0+ minimum requirement which supported only from

问题 I've got a web app I recently upgraded from springboot to springboot 2. When I deploy it to Tomcat 8 it seems to start but doesn't start fully.
