No data loaded when running publish/subscribe sample on Tomcat

Question

I have Tomcat 6.0 running as a .jsp handler with Apache 2.2 using the mod_jk connector. I've configured the samples/ context to be handled via Tomcat. Everything seems to be working fine -- I can access the files and launch .jsp files via my web browser.
But when I try to fire up the DataPush example, I get no results from BlazeDS. Here's the procedure I am using:
1. Start the feed by running http://localhost:8080/samples/testdrive-datapush/startfeed.jsp
2. Run the Flex side: http://localhost:8080/samples/testdrive-datapush/index.html.
3. Press the "Subscribe to 'feed' destination."
Using Firebug within Firefox, I can tell that it's attempting to access a streaming channel. There are two requests:
1) http://localhost:8080/samples/messagebroker/streamingamf
2) http://localhost:8080/samples/messagebroker/streamingamf?command=open&version=1
Request #1 comes back with a plain-text "Loading..." response.
Request #2 returns an error message: The request sent by the client was syntactically incorrect ().
Incase it matters, I have been playing around with the config files in previous tests. For this test, I deleted the samples.war, and samples/ directory from Tomcat. Then I copied the original samples.war back in and restarted Tomcat to redeploy. I would think that this erases all of my configuration settings -- but it does not seem to be doing that (The Data Push/Pull does NOT default to streaming from the Turnkey package, yet when I hit the service again, it always tries to perform streaming first -- as I had told it to do in a previous configuration).
So I have two questions:
1. Why doesn't the example work using streaming?
2. Why aren't my configuration files being reloaded when I restart Tomcat?
TIA

Hi,Alex
Thanks for your advies, But it do not works.
with a Apache Fronting Tomcat, the following config is work:
channel 1 : Hi. Here are answers to your questions.

>>>1. Why doesn't the example work using streaming?
>Some proxies buffer the response that is sent back to the client. This causes streaming connections to not work. This is a known issue with the mod_jk connector. Take a look at the  following bug for more info.

>>>2. Why aren't my configuration files being reloaded when I restart Tomcat?
>Did you recompile the sample application after changing the configuration? The configuration information is used by both the server and the client and is compiled into the client. You will need to recompile the client application using the new configuration files if you want your changes to be picked up. Note that is is possible to load the configuration information into the client application at runtime but that's not how the sample applications were built. If you are interested in loading the configuration information at runtime here is a blog posting that gives an example.
