Start two Play! application on same name server - apache

Question

I'm trying to run two different web application on the same server, with the same domain name, like :
www.example.com/app1
www.example.com/app2
The applications are developed using Play! framework, and I'm using Apache as a reverse proxy. I tried to follow the online guide, set up the virtual host and etc..., but nothing seem to works, only the first app is reacheble, while the second isn't.
This is as far as I got untill now with my apache config file :
<VirtualHost *:80>
ProxyPreserveHost On
DocumentRoot "/home/App1/"
ServerName http://www.example.com/app1
ProxyPass /excluded !
ProxyPass / http://127.0.0.1:9000/app1
ProxyPassReverse / http://127.0.0.1:9000/app1
LogLevel debug
</VirtualHost>
<VirtualHost *:80>
ProxyPreserveHost On
DocumentRoot "/home/App2"
ServerName http://www.example.com/app2
ProxyPass /excluded !
ProxyPass / http://127.0.0.1:8000/app2
ProxyPassReverse / http://127.0.0.1:8000/app2
LogLevel debug
</VirtualHost>
Route, code and everithing are correct, it's just that I can't get these apps work together.
(I also tried to implement the load balacer showed on the online guide, but it didn't work)
Thanks.

Answer 1

I don't think you can have two virtual hosts with the same host name - that doesn't make sense, virtual hosts are for serving different host names, for example, for serving foo.example.com and bar.example.com.
I think what you want is something roughly like this:
<VirtualHost *:80>
ProxyPreserveHost On
ServerName www.example.com
DocumentRoot /some/path/to/something
ProxyPass /excluded !
ProxyPass /app1 http://127.0.0.1:9000/app1
ProxyPassReverse /app1 http://127.0.0.1:9000/app1
ProxyPass /app2 http://127.0.0.1:8000/app2
ProxyPassReverse /app2 http://127.0.0.1:8000/app2
LogLevel debug
</VirtualHost>

James' answer is correct, you just need to fit it to your needs, I shoot that works out of the box:
<VirtualHost *:80>
ProxyPreserveHost On
ServerName www.example.com
ProxyPass /app1 http://127.0.0.1:9000/
ProxyPassReverse /app1 http://127.0.0.1:9000/
ProxyPass /app2 http://127.0.0.1:8000/
ProxyPassReverse /app2 http://127.0.0.1:8000/
</VirtualHost>
Note, that you will need to prefix EVERY route in your apps to reflect the folder path with app1 and app2, like:
foo site
bar site
