step-3. go to browser write localhost:port/project name eg. localhost:8080/pos (here my tomcat run on port 8080)

Done....

You can access your application from: http://localhost:8080/sample

Deploying or redeploying of war files is automatic by default - after copying/overwriting the file sample.war, check your webapps folder for an extracted folder sample.

If it doesn't open properly, check the log files (e.g. tomcat/logs/catalina.out) for problems with deployment.

You just need to put your war file in webapps and then start your server.

it will get deployed.

otherwise you can also use tomcat manager a webfront to upload & deploy your war remotely.
