Tomcat runs two projects with different port numbers

In order to run multiple projects with different port numbers on the Tomcat server project, its configuration needs to be modified.

Step 1: Edit Server.xml

Open Tomcat’s server.xml file, which is usually located at <tomcat_home> /conf</tomcat_home> directory.

Replace the port attribute with the desired port number.

Step 3: Add Context Element

<Context path="/my-app" docBase="/path/to/deployment" />

Replace the path attribute with the application's context path and the docBase attribute with the deployment directory path of.

Step 4: Create a WAR file

For each application you want to deploy, create a WAR (Web Application Archive) file.

Step 5: Deploy the WAR file

Copy the WAR file to the corresponding webapps directory:

• Default port (8080): <tomcat_home>/webapps</tomcat_home>
• Other port numbers: <tomcat_home>/webapps/ ROOT</tomcat_home>

Step 6: Restart Tomcat

Restart the Tomcat server to apply these changes.

Now you can access the deployed application through the specified port number:

• Default port (8080): http://localhost :8080/my-app
• Other port numbers: http://localhost:8090/my-app
