信息: JSR 356 WebSocket (Java WebSocket 1.1) support is not available when running on Java 6. To suppress this message, run Tomcat on Java 7, remove the WebSocket JARs from $CATALINA_HOME/lib or add the WebSocket JARs to the tomcat.util.scan.DefaultJarScanner.jarsToSkip property in $CATALINA_BASE/conf/catalina.properties. Note that the deprecated Tomcat 7 WebSocket API will be available.

解决：是JDK版本问题，JDK6.0不支持WebSocket，需要7.0及以上。将Tomcat的JDK版本改为7或者以上
