Problem with installing a plugin

Nagios Nagios Plugins support

Hi ,
I have written a sample java plugin… In the command definitions i have added this line

define command{
command_name check_Myplugin
command_line $user1$/java -cp “path to my class file” “Myclassname”
}

I have edited localhosts.cfg also
but nagios saying "(return code of 127 is out of bounds - plugin may be missing)"
I know this error occurs if plugin is missing. but i have clearly specified the path…
What should i do get rid of this error.

in “java” in PATH? put full path to “java” interpreter into command definition
