I've a domain, say www.domain.com. And I've developed a java web application, say jwa. Now I want to install the same app for different clients using subdomains, what is the best solution possible?
something like "client1.domain.com" points to "client1" (renamed jwa)
I know we can get client1.domain.com/client1/ but client1 twice isn't good. or at least Can we get client1.domain.com/jwa/, without have multiple tomcat instances? btw, I'm running apache http server on the same server and using "proxy_module" for java/tomcat apps
Regards

You dont need multiple Tomcat instances - you can point multiple clients across multiple subdomains to use the same web app
BUT be sure that this fits with your business use case - i.e. do you actually want multiple instances of the webapp running, or a can single instance serve all your clients.
I'm referring to the branding/logo/shared data/look-and-feel etc - is that common across all clients?
Lets assume it is.
With an Apache configured, the right way is to use VirtualHost
directives along with mod_proxy.
A configuration like this on the Apache side should work - create one per subdomain, and point the ProxyPass
and ProxyPassReverse
to the Tomcat web app
<VirtualHost *:80>
ServerName client1.domain.com
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass /jwa http://client1.domain.com:8080/jwa
ProxyPassReverse /jwa http://client1.domain.com:8080/jwa
</VirtualHost>

Apache docs have lots of examples of VirtualHost configuration
There is also a solution without Apache httpd, you can configure Host entires within Tomcat server.xml but Apache is a better place to manage your domain URLs
