dispatcherutil.sh list is not working

Hello

I'm new in SAP Basis. I want to check the status from the Dispatcher on our system.

If i executed the dispatcherutil.sh i'll get this error:

dispatcherutil.sh: line 36: /bin/java: No such file or directory

USAGE: sh dispatcherutil.sh <command> <dispatcherName> <option>
Output without any commands:
command One of: test/add/delete/start/suspend/resume/stop/softstop/list/gui/set_jdbc_url/set_default
dispatcherName Not required for commands "list", "gui" and "set_jdbc_url", but is mandatory for others
option One of checkconfig/runonce in combination with command "test"
JDBC URL with <prefix>_rt user in combination with command "set_jdbc_url"

What is the reason and what can i do?

Thank's for helping.
