Cannot connect to openfire through jmx

I am running openfire in a hp unix server.

And I found the memory useage is not normal.

So I add the INSTALL4J_ADD_VM_PARAMS “-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false”.But I cannot connect to the jmx server running in the openfire.

Anybody know how to solve this?

java -version

java version “1.6.0.02”
