run jsp and php from the same server and domain name

Install Tomcat on the server and run in on port 8080 for example. Make sure your JSP is working fine through Tomcat. Then use Apache’s mod_proxy to forward requests that are going to /jsp/ to Tomcat. Here’s a link with some more info:

You can do that by using Tomcat and Apache.

Install Apache and Tomcat:

sudo apt update
sudo apt install apache2
sudo apt install tomcat9
sudo a2enmod ssl
sudo a2ensite default-ssl.conf
sudo systemctl restart apache2
sudo apt install libapache2-mod-jk

Configure mod_jk in /etc/apache2/workers.properties:

worker.list=tomcat
worker.tomcat.type=ajp13
worker.tomcat.host=localhost
worker.tomcat.port=8009

Configure Apache Virtual Host: Edit /etc/apache2/sites-available/000-default.conf and add:

<VirtualHost *:443>
    ServerName website.com
    SSLEngine on
    SSLCertificateFile /path/to/cert.pem
    SSLCertificateKeyFile /path/to/key.pem

    Alias /php /var/www/html/php
    <Directory /var/www/html/php>
        AllowOverride All
    </Directory>

    JkMount /jsp/* tomcat
</VirtualHost>

Restart Apache and Tomcat

sudo systemctl restart apache2
sudo systemctl restart tomcat9

This will serve PHP from /php/ and JSP from /jsp/ under the same domain.
