tomcat8

I tried an SSE (Server-Sent-Events) using java on tomcat 8.0. Here are few things I noticed. I click a button that automatically makes a request to the servlet. Servlet's GET method gets executed which returns an event stream. Once the full stream is received, the page again automatically makes another request which receives the same data again!!! I don't have an infinite loop there!!! What is actually happening on the server? In normal scenarios, tomcat creates a thread to handle every request. What is happening now? What is the correct way to ensure that the event stream is sent only once to

I have an embedded Tomcat server that is serving static files just fine. But when I add the buildPath code required to get @WebServlet working, it doesn't work in one of my projects (there are plenty of differences between projects... about 50K lines worth). I get the following error before web.xml is even read (I know this from strace -ff ). org.apache.catalina.LifecycleException: Failed to start component [StandardServer[-1]] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:167) at org.apache.catalina.startup.Tomcat.start(Tomcat.java:367) at app.http.TomcatServer

First of all, I would like to say that there is plenty of pages on StackOverflow and I tried all I found related, but I am doing something wrong.

Unfortunatelly when I change some

I found other Questions and Answers dealing with getting the NetBeans IDE to talk to the Apache Tomcat servlet container. But they seem to be out of date or involve extraneous steps. I remember the process as being less complicated on my Mac. But I cannot remember the exact steps. Indeed, getting Tomcat to talk to NetBeans is fairly simple though not obvious. Java EE edition of NetBeans If downloading NetBeans, grab an edition of NetBeans IDE already bundled with Tomcat. You may need to customize the installation to get Tomcat, as described in this Question . But that version of Tomcat is

Trying to Run Vaadin 8.1 app under Java 9 prerelease in IntelliJ 2017.2.2 I was able to build a vaadinjavanine.war using a fresh project and host the same using Jetty Server. I ended up trying to deploy the generated war to a tomcat server. But, during the startup of the tomcat server, I am getting the following exception: 21-Aug-2017 22:53:38.830 SEVERE [localhost-startStop-1] org.apache.catalina.startup.ContextConfig.processAnnotationsFile Unable to process file [/Library/Tomcat/apache-tomcat-8.0.22/webapps/vaadinjavanine/WEB-INF/classes/module-info.class] for annotations org.apache.tomcat

I developed a new application and it runs perfectly on Tomcat 7! But I am trying to deploy the same WAR on Tomcat 8 and I am getting a NullPointerException .
