Thanks so much for getting back to me.
It's just a java process that is supposed to process requests from docy.
This all works when it's just one tomcat as a client and one tomcat as a
server with no apache http server infront of the server.
Here is part of the request I edited out...

(worker2) request body to send 0 - request body to resend 0
So this is where it ends, this request never makes to the tomcat server.
Well, it probably does. But to me, it looks like Tomcat does not know
what to do with it. Or else, I misinterpret what you are saying below,
or there is a piece missing in your explanation.
Note 1:
The web context on the server isn't called docy.
It's the doc_(The name of the project I am working on) which I have had to
edit out.
Note 2:
I have a simple Helloworld.jsp also running on the server which I can send
notmal HTTP requests to via the apache server.
So I am 100% confident all the bog standard stuff is set up correctly.
Well yes, it looks like indeed the Apache <-> mod_jk <-> Tomcat
communication part is set up properly and is working.
But it would seem that the request you are sending to Apache is a POST
request, to the URL "/docy" (or whatever). Then mod_jk is trying to
forward this request to Tomcat, using the same request URL "/docy".
However, I have a feeling that, although this request is a POST
(supposed to contain a request body), and the HTTP headers seem to
indicate that there should be a body, in fact it does not contain any
request body.
Another thing is that for Tomcat to respond sensibly to a request for
"/docy" (or whatever), should have an application at the Tomcat side
that is set up to respond to "/docy" (or whatever) with something.
To tell you the truth, I am now lost, and I don't know if what you are
testing through Apache, and for which you have been showing the logs,
really represents what you are trying to achieve, or if maybe you are
testing different things when going through Apache as opposed to when
you are not.
Tell me some more things :
When you have your initial setup, where one Tomcat talks to the other
directly,
- which port do you use on the "server" Tomcat ?
(can you show the corresponding <Connector> of your Tomcat server.xml file)
- how does the "client" Tomcat connect to that port and send a request
to it ?
- is that request then pure HTTP ? (even if inside, there is a SOAP message)
- and later, when you have changed your setup to have the "client
Tomcat" now talk to the Apache server, instead of to the "server Tomcat"
directly, are you using the exact same request from the client Tomcat ?
Coming back on your Note 2 above : it would probably be useful to
compare the mod_jk log between these two cases : when you are requesting
the URL /HelloWorld and when you are requestion /docy (or whatever), and
look where the difference is.
What may also be useful, is to configure this within your Tomcat :
http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html
(AccessLogValve)
There is probably a commented-out example is your server.xml. Uncomment
it. It will log the requests which Tomcat does receive, through
whatever port.
