Hi, after installing Tomcat, I had a look on the installed examples. There was a websocket example, a simple chat.
I tried to implement it on my GWT project but I couldnt get it working. Thats what I did: *1) *I copied classes from the example into my gwt server directory: ChatWebSocketServlet.java<http://svn.apache.org/repos/asf/tomcat/tc7.0.x/trunk/webapps/examples/WEB-INF/classes/websocket/chat/ChatWebSocketServlet.java> (extends WebSocketServlet) HTMLfilter <http://www.java2s.com/Code/Java/Servlets/HTMLfilterutility.htm>(does nothing special) *2)* Include missing jars into my build path (tomcat-coyote.jar , catalina, tomcat-juli.jar, tomcat-util.jar) *3) *Added the following to my web.xml: <servlet> <servlet-name>wsChat</servlet-name> <servlet-class>de.mash.project.server.ChatWebSocketServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>wsChat</servlet-name> <url-pattern>/Mash</url-pattern> </servlet-mapping> *4) *Implemented the JS-Code from here to my html page. I changed the following to fit my needs: Changed Chat.connect('ws://' + window.location.host + '/examples/websocket/chat'); to Chat.connect('ws://' + window.location.host + '/Mash'); in the JS Code. The problem is, that the connect()-Method doesnt work, and I cant get a socket (I end up in the JS Chat.onerror()-Method). Im still using the Build-In Jetty for debugging, so I dont got any meaningful error so far. The one I get from Console is mentioned below. (But its jetty, so Iam not expecting it to work). I *Debuged as Webapp *(on external Server): Then I choose my projects war-folder in apache webapp folder: But didnt got any errormsg in my console log. Is this the proper way to use tomcat for debugging? So... Iam not sure if there is a *misstake in my web.xml, a bad connection string on the connect()-Method*, or if Iam totally wrong and its not that easy to get it running... Any advice, help, suggestions are appreciated. Regards, Manuel ERROR from Jetty: Iam not wondering about this one, since I want to use Tomcat Websockets...
