These are the settings I used:


Configuration in Apache:

In file <APACHE_HOME>/conf/httpd.conf I add this row:

# Include mod_jk configuration file
Include conf/mod-jk.conf

------------------------------------------------------------------------

Create a mod-jk.conf into <APACHE_HOME>/conf

# Load mod_jk module
# Specify the filename of the mod_jk lib
LoadModule jk_module modules/mod_jk.so

# Where to find workers.properties
JkWorkersFile conf/workers.properties

# Where to put jk logs
JkLogFile logs/mod_jk.log

# Set the jk log level [debug/error/info]
JkLogLevel debug

# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

# JkOptions indicates to send SSK KEY SIZE
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories

# JkRequestLogFormat
JkRequestLogFormat "%w %V %T"

# Mount your applications
JkMount /application/* loadbalancer

# You can use external file for mount points.
# It will be checked for updates each 60 seconds.
# The format of the file is: /url=worker
# /examples/*=loadbalancer
JkMountFile conf/uriworkermap.properties

# Add shared memory.
# This directive is present with 1.2.10 and
# later versions of mod_jk, and is needed for
# for load balancing to work properly
JkShmFile logs/jk.shm

# Add jkstatus for managing runtime data
<Location /jkstatus/>
JkMount status
Order deny,allow
Deny from all
Allow from 127.0.0.1
</Location>

------------------------------------------------------------------------

File workers.properties:

# Define list of workers that will be used
# for mapping requests
# The configuration directives are valid
# for the mod_jk version 1.2.18 and later
worker.list=loadbalancer,status

# Load-balancing behaviour

# Peso de nuestro nodo. A más peso, mas peticiones recibe.
#worker.nodo1.lbfactor=1

# Definimos el nodo Nodo2
worker.nodo2.port=8900
worker.nodo2.host=localhost
worker.nodo2.type=ajp13
worker.nodo2.lbfactor=1

# Status worker for managing load balancer
worker.status.type=status

Hi all,
I hope than any can help me with this problem.
The topology that I try to do is that:

[App-1]====>(Post request)====>[Balancer]=====>[App2 - JBoss instance]

* The parameter sended via Post is a XML that represents an entity

The JBoss server is listen the port 8009 but mi App2 have a service that is listen the port 8900, this service is configured with Mule-ESB.

I try this configurations:
1.- Worker port: 8900
In this case App2 receive an unexpected message (see result.png)
2.- Worker port: 8009
The message is sended to App2 by balancer (I know that because the message in "access.log" is: "127.0.0.1 - - [23/Aug/2011:15:00:47 -0500] "POST /orderReceiver HTTP/1.1" 404 988") but this is not attended by App2
3.- Worker port: 8009 and App2 listen the same port 8009
The same result as scenario #1

In case #1, when I set "JkLogLevel debug" in mod-jk.conf I see that the XML is sendend but preceded by some meta-information, I suspect that this information is nos recognized by my service and for this reason I obtain the result shown in result.png

I've made a trivial app that recive and print a GET request and print it in console, this app works fine. I deploy this app in a default Tomcat (with default ports).. I can't test this app with POST request.

So, my questions are:
1.- mod_jk allow the POST request? It's necessary to do any change in my configuration to receive POST request?
2.- Exist any difference between the original POST and the POST received by Mule-ESB?
3.- It's necessary to do any other configuration in my JBoss instance?

I've atached my configuration files.


Any help is welcome,
