LispConnector.go: Connect to Lisp port failed

My Tomcat happily runs servlets. But when I run the servlet that's 
compiled with jlinker and is supposed to connect to my lisp app, I get 
HTTP status 500, javax.servlet.ServletException: LispConnector.go: 
Connect to Lisp port failed.

My compiled Lisp application is running on the same machine. When I 
start it up, I see
;;ji(1.1): Advertising Lisp server at localhost:4321.
;;jn(1.1)jNotifyLisp: starting up.
;;js(1.1)jLinkServer: starting up.
; Fast loading from bundle code/sock.fasl.
;   Fast loading from bundle code/defftype.fasl.
;;ji(1.1): Expecting announceServer message from Java.

nmap shows me that 4321 is open, and I can telnet to it. I've disabled 
iptables to make sure the firewall is not the culprit. I only start my 
Lisp app after starting Tomcat.

Any ideas on how I could troubleshoot this?


P.S. For those keeping score at home, the generate-application + jlinker 
issue was easily resolved (thank you, Mikel Bancroft!) by adding 
:process in the generate-application call, like so:

(generate-application "myapp" "delivery"
	'(:process "load-myapp.lisp")
	:allow-existing-directory t
	:include-compiler t :discard-compiler t :runtime-bundle t)
