No way I can make it work !

Looks like a good start, but it is missing some informations. There is no way I can make it work with NRPE, even if I run it ok directly in my shell account :

[nagios@myserver ~]$ /usr/local/nagios/libexec/check_jmx -U service:jmx:rmi:///jndi/rmi://localhost:8999/jmxrmi -O java.lang:type=Memory -A HeapMemoryUsage -K used -I HeapMemoryUsage -J used -vvvv -w 800000000 -c 1500000000
JMX WARNING HeapMemoryUsage.used=842512960{committed=1042808832;init=1073741824;max=1042808832;used=842512960}

I checked a lot of things, but I am still stuck with the following message :

[nagios@myserver ~]$ /usr/local/nagios/libexec/check_nrpe -H localhost -c check_jmx
NRPE: Unable to read output
