Alternatively try:
Code:
ssh myRemotehost 'ps ww -fu tomcat' | awk '/[o]rg.apache.catalina.startup.Bootstrap/{pid=$2} END{if (pid) print "tomcat (pid " pid ") is running..."; else { print "tomcat stopped or dead"; exit 1 }}'

The [o] is not really necessary, since the ps is run on the remote host and awk on the local host, but then you could reuse the code to check on the local host too... I added an exit statement so you can also check the return code..
The check needs to be in the END part like Corona688 suggested, otherwise you cannot conclude that it is not running.
