Question

I am using a Tomcat server that can be accessed via https://<IP>:8443/webappname (works for all web apps)

This tomcat server is also configured to be accessed by domain like: https://mydomain123.com/webappname

However, not all webapps are accesible. How to make a new web application in the webapps folder accessible like the above (domain).

Answer 1

If Apache (httpd) is running in front of Tomcat, it is most likely using mod_proxy to forward requests for some webapps to Tomcat. Since it works for some webapps but not others, try looking into the Apache config files (usually under /etc/apache2 in Linux) for lines starting with ProxyPass, similar to this:

ProxyPass /example ajp://localhost:8009/example
ProxyPassReverse /example ajp://localhost:8009/example

There should be two lines like this for each webapp accessible through Apache. Just copy those lines and change the name of the webapp (“example” above) to proxy other apps.

If you don’t find any ProxyPass line in the Apache config files, it may be using a different module, like mod_jk.
