Hi Christopher, I've never used tcpdump before, but it seems the trick is knowing how to configure it with the various switches to extract what one wants. I took a stab at it below, but I can't find much meaning in it. This snippet captures the time when Adobe accesses the webaddress. Is there a better command you can give me to use to give more relevant information? (below: xx.xxx.xxx.163 = client and xx.xxx.xxx.196 = server)
Hi Andre, yes there's a few more JkMounts that I didn't mention since they're unrelated, and I corrected below the additional typos you found. Also, the initial part of the mod_jk.log below was critical to understanding the problem (I'll edit it to make it more obvious -- see THE CAPITAL LETTING inside the mod_jk snippet below).

I've corrected it below. Also, switched to plain text instead of HTML. Thanks Christopher -- I eliminated the attachments. I've tried to make it more readable for color-blind people, use in-text clues, etc. below. I've also included my workers.properties file. You're right that the JkMountCopy isn't needed (I was desperate to find a solution and this was one attempt to fix it that had no effect). I was worried about the colon in the mod_jk.log file lines as well, but since it is consistently everywhere, I assumed it was a formatting issue related to mod_jk. I'm not switching ports or changing protocols. I'm trying to keep everything simple. The address you pointed out is the IP address for host3.mydomain.com. As an experiment, I replaced host3.mydomain.com with the actual IP address for the server (used by VirtualHost) in the input field for Host URL in Adobe's software so there's be no mistake which IP address would receive Adobe's request, but the mod_jk.log appears exactly the same. --------------------original message is below--------------- Hello. I'm trying to setup Adobe's Flexbuilder 4.6 software to access mydomain.com/mywebapp using port 80 on Apache Webserver 2.2.21 and connect using mod_jk 1.2.32 on a remote Linux CentOS 6.2 server. I'm puzzled by the mod_jk.log file, which I've included a snippet below and attached as a text file. I also attached an image of Adobe Flexbuilder's wizard. As you can see from the image, this wizard has a button called "Validate Configuration" that attempts to connect to the remote server provided in the input field labeled "Root URL". If I enter the following into this Root URL field http://mydomain.com:8080/mywebapp the Adobe Flashbuilder software states that a connection was successfully made to the server. However, if I enter the following instead: http://mydomain.com/mywebapp the Adobe Flashbuilder software states that it cannot connect to the server. When I review the mod_jk.log file (attached as a file and also shown below), I see Adobe's request in the 2nd line, where the mod_jk.log entry reports a missing uri map for host3.mydomain.com:/mywebapp/flex_wizard_...

In this case, a match was found with JkMount and a worker assigned, and so mod_jk seems to be working.

Can you see anything in the log file that would indicate the address I entered is different than the address Adobe is using, that could explain this? I really need this working, so any help MUCH appreciated.
