about tomcat monitor

[Jack_lai]

DEAR ALL:
I want to monitor my tomcat service usage in zabbix.

In Zabbix server side ,I modify two config file;
one file "/etc/zabbix/zabbix_server.conf" ,I modify
" JavaGateway=192.168.1.100
JavaGatewayPort=10052
StartJavaPollers=5"

other file "/etc/zabbix/zabbix_java_gateway.conf"
" LISTEN_IP=192.168.1.100
LISTEN_PORT=10052
START_POLLERS=5"


In Tomcat client server ,I modify "C:\AF37\Tomcat6\bin\catalina.sh" and add this content
"CATALINA_OPTS="$CATALINA_OPTS
-Dfile.encoding=utf-8
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.port=12345
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=192.168.1.200" #modify tomcat server ip"

After above config , in zabbix web ,I got this error message "Connection refused (Connection refused): service:jmx:rmi:///jndi/rmi://192.168.1.200:12345/jmxrmi"

So which config is wrong????
