is your webapplication creating a session? if not, then there wont be a
cookie, and mod_jk uses this cookie to determine server affinity.
and if you dont have sessions, you don't need session affinity

I have an http packet sniffer and it is reporting that there are no cookies
returned by apache.
Just to recap what I have done:
1. IBM HttpServer 2.0 with mod_jk on redhat linux
2. worker.properties has a load-balancer worker fronting two tomcat workers
over ajp13. it's sticky session property is set to True.
3. In the server.xml, the jvMRoute attribute of Engine (in both tomcat
instances) have their respective worker names (no case difference or silly
spelling mistakes).
There is no cookie. Is there another step that I am missing to enable
session affinity?

JSESSIONID is a non-persistent cookie and you can check its presence easily
using a Netscape Navigator or FireFox.
In Firefox go to Tools->Options, Options Popup appears.
Select Privacy in the left section, to get the privacy options on the right
side of the popup
Expand the Node "Cookies" and click on button View Cookies.
You can see the cookie JSESSIONID with its value.
If you don't see the cookie, then definitely there is some issue.

how do you verify that you don't have a cookie?
I suggest using LiveHttpHeaders (firefox/mozilla) or TCPMonitor

Yes I did
jvmRoute is set to the worker name.
still, no jsessionid cookie.

have you set jvmRoute in your engine element (server.xml)?
this is how mod_jk does session affinity

I have IBM HttpServer 2.0 (it is an apache essentially) fronting two

I have configured a load balancer worker to spray load across two workers
representing these two tomcat instances.
And it works.
The problem is I do not see a session id cookie in the response, so I am
not
sure if it is maintaining session affinity.
I have configured the load balancer worker for session affinity with this
directive in worker.properties:
worker.lb_worker.sticky_session=True
What am I missing?
What is the exact name of the cookie that mod_jk injects?
I apologize if this is not the right mailing list for connector questions
and will appreciate if someone could point me to it.
Thanks in advance
