I am trying to front my tomcat installation with Apache 2 webserver. The idea is to let apache handle the SSL/https part and then forward the normal request to the tomcat on same machine running on port 8080.

As mentioned here, I am using the following configuration :

<VirtualHost *:*>
 ProxyPreserveHost On
 ProxyPass / http://127.0.0.1:8080/
 ProxyPassReverse / http://127.0.0.1:8080/

 ServerName my-server-name.com
</VirtualHost>

Listen 443
NameVirtualHost *:443
<VirtualHost *:443>
 SSLEngine On
 SSLCertificateFile /etc/letsencrypt/archive/my-server-name.com/cert-file
 SSLCertificateKeyFile /etc/letsencrypt/archive/my-server-name.com/key-file
 SSLCertificateChainFile /etc/letsencrypt/archive/my-server-name.com/chain-file

 ProxyPass / http://127.0.0.1:8080/
 ProxyPassReverse / http://127.0.0.1:8080/

</VirtualHost>

The above configuration is resulting in :

1. Visiting http://my-server-name.com is opening the tomcat landing page


2. Visiting https://my-server-name.com is opening the apache landing page

But what I expect is to always redirect to https://my-server-name.com which should open the tomcat landing page (which will evantually be replaced by my application deployed on the ROOT)

Can someone please guide me or any pointer to a step by step guide to front tomcat with apache for https to http handling

The first vhost isn't needed as it seems and the NameVirtualHost directive can also be dropped, resulting in:

Listen 80 
Listen 443

<VirtualHost *:80>
 RewriteEngine On
 RewriteCond %HTTP_HOST ^(.*)$
 RewriteRule ^(.*)$ https://%1$1 [R=Permanent,L,QSA]
</VirtualHost>

<VirtualHost *:443>
 SSLEngine On
 SSLCertificateFile /etc/letsencrypt/archive/my-server-name.com/cert-file
 SSLCertificateKeyFile /etc/letsencrypt/archive/my-server-name.com/key-file
 SSLCertificateChainFile /etc/letsencrypt/archive/my-server-name.com/chain-file

 ProxyPreserveHost On
 ProxyPass / http://127.0.0.1:8080/
 ProxyPassReverse / http://127.0.0.1:8080/
</VirtualHost>

On my server I have this configuration for your question:

Listen 80
Listen 443

<VirtualHost *:80>
 ErrorLog /var/log/apache2/myserver.error.log
 CustomLog /var/log/apache2/myserver.log combined

#settings for AJP to tomcat
 ProxyPass / ajp://localhost:8009/
 ProxyPassReverse / ajp://localhost:8009/

</VirtualHost>

<VirtualHost *:443>
 ErrorLog /var/log/apache2/myserver.error.log
 CustomLog /var/log/apache2/myserver.log combined

 <Proxy *>
 AddDefaultCharset Off
 Order deny,allow
 Allow from all
 </Proxy>
 SSLEngine on
 SSLCertificateKeyFile /etc/letsencrypt/live/myserver.com/privkey.pem
 SSLCertificateFile /etc/letsencrypt/live/myserver.com/cert.pem

#settings for AJP to tomcat
 ProxyPass / ajp://localhost:8009/
 ProxyPassReverse / ajp://localhost:8009/

</VirtualHost>

I forward via AJP 8009, this is usually activated in tomcat. In apache the mod_proxy_ajp has to be enabled. But the configuration would work with http too.
Difference from my config to your's:
I don't have

<VirtualHost *:*>

and

NameVirtualHost *:443
