virtual hosts apache/tomcat

Ok, finaly have apache and tomcat running both on port 80.

I have created the following dir's
/export/home/www.someserver.com
/export/home/mnt.someserver.com

This will be the location of http://www.someserver.com and
http://mnt.someserver.com

To test I have placed a document named info_www.txt in
/export/home/www.someserver.com and placed info_mnt.txt in
/export/home/mnt.someserver.com I have created 2 virtual hosts like
this in
my httpd.conf:
_____________________________________
NameVirtualHost *

<VirtualHost *>
ServerAdmin Me.DeleteThis@domain.com
DocumentRoot/export/home/www.someserver.com
ServerName www.someserver.com
ErrorLog /export/home/log/errorlog-2
CustomLog /export/home/log/customlog-2 custom
</VirtualHost>

<VirtualHost *>
ServerAdmin Me.DeleteThis@domain.com
DocumentRoot /export/home/mnt.someserver.com
ServerName mnt.someserver.com
ErrorLog /export/home/log/errorlog-1
CustomLog /export/home/log/customlog-1 custom
</VirtualHost>

If open www.someserver.com/www.txt this is correct and working Then I
open www.someserver.com/info_mnt.txt and this also opend. This should
not be possible info_mnt.txt should only be availabale true the domain
mnt.someserver.com. How is it possible I also can open it true
www.someserver.com ?

I also like to run jsp files under www.someserver.com and
mnt.someserver.com ... people are not allowd to open documents from
mnt in the www part...... How do I change the webapps dirs and make
them available under http://mnt.someserver.com and
http://www,someserver.com ?

Thanks already,
Regards. Johan.
