the problem tomcat 7 using java 6.

hint following line of catalina.out log:

info: jsr 356 websocket (java websocket 1.0) support not available when running on java 6. suppress message, run tomcat on java 7, remove websocket jars $catalina_home/lib or add websocket jars tomcat.util.scan.defaultjarscanner.jarstoskip property in $catalina_base/conf/catalina.properties. note deprecated tomcat 7 websocket api available. 

i switched java version tomcat creating setenv.sh in tomcat-7/bin read default on startup catalina.sh set environment variables.

setenv.sh:

export java_home=/usr/java/jdk1.7.0_09
