I saw this after I had posted my message.

Sure, just do a "grep java"

#!/bin/sh

kill -9 `lsof -i tcp:$1 | grep java | awk '{ print $2;}'`

Another thing you could is to look for the port that is LISTENing.

-------------- snip  ----------
#!/bin/sh
#
#  portslay:  kill the task listening on the specified TCP port
#

kill -9 `lsof -i tcp:$1 | grep LISTEN | awk '{ print $2;}'`
-------------  snip -------------
