Alex,
It sounds like you're running multiple virtual hosts from one Tomcat instance.
At least that's the clue I get from the following line:
In every /Catalina/[hostname]/manager.xml is
I'm guessing you meant %CATALINA_HOME%\conf\Catalina\[hostname]\manager.xml ?
There's an article on the Tomcat Wiki that describes a setup with virtual
hosts. One of the issues it covers is the manager application.
The article: http://wiki.apache.org/tomcat/TomcatDevelopmentVirtualHosts
It's a bit dated, but I think still accurate.
The key is to create a manager application for each virtual host. This means
you'll copy the manager application over to each virtual host's appBase, and
the manager.xml context file is then just a copy of what is currently shipped
with Tomcat.
As Pid has said, disk space is cheap, so creating completely separate virtual
hosts is the cleanest way to accomplish this.
I've set up systems like this for production, and it seems to work quite well.
just my two cents . . . .
