Error message "jrcmd: not found" when I execute a script

I am getting the error below when I execute a script: > Ksh: line 1: jrcmd: not found When I execute the same command in weblogic server, I get the output, but executing the same command inside a script it gives me the error message. This is the script: #!/bin/ksh process_id=`ssh -q account@servername -n "pa -ef |grep weblogic|great -v "grep""|awk '{print $2}' ssh -q account@servername -n "jrcmd $process_id print_threads > /tmp/thread.txt" Can I expect any answer?
