Deploy websocket services with tomcat 8.0.33 by tomcatRun task,but response 404 error when send a request from client browser (chrome or ie 11): WebSocket connection to 'ws://localhost/bboss-websocket/Websocket1Action' failed: Error during WebSocket handshake: Unexpected response code: 404

but deploy directly same websocket services with tomcat 8.0.33 is ok.

Same problem here with Java9 & Tomcat9.0.6 Has anybody tried this plugin: https://github.com/gretty-gradle-plugin/gretty ?

Edit: Fixed it by removing (accidentally added) tag <absolute-ordering/> from my web.xml. build.gradle:

dependencies {
    // JavaEE APIs
    providedCompile group: 'javax.servlet', name: 'javax.servlet-api', version:'4.0.0'
    providedCompile group: 'javax.servlet.jsp', name: 'javax.servlet.jsp-api', version:'2.3.1'
    providedCompile group: 'javax.annotation', name: 'javax.annotation-api', version: '1.3.2'
    providedCompile group: 'javax.websocket', name: 'javax.websocket-api', version:'1.1'
    
    // Tomcat
    def tomcatVersion = '9.0.6'
    compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-websocket', version: tomcatVersion
    tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}",
    //     "org.apache.tomcat.embed:tomcat-embed-logging-juli:9.0.0.M6",
           "org.apache.tomcat.embed:tomcat-embed-jasper:${tomcatVersion}"
}
