show subdomain as url for tomcat application

Hello,

i have many projects in tomcat webapps folder. say my webapps has project1.war and proejct1 folder, project2.war and project2 folder i have also created subdomain proejct1.mydomain.com and project2.mydomain.com and redirected to respective folder so when i type project1.mydomain.com in url, browser automatically goes to project1 but the url now shows my droplet/project1 my requirement is that the url should show project1.mydomain.com

my apache conf file is

<VirtualHost *:80>
ProxyPreserveHost On

# this will pass all the requests from httpd to tomcat7
     ProxyPass / ajp://localhost:8009/ 
     ProxyPassReverse / ajp://localhost:8009/  
</VirtualHost>

my tomcat server.xml

   <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">

      </Host>

how can i achieve this

Thanks and Regards, Pranav C Lunavat
