Deploying WAR Files in Tomcat 7

Question:

After copying a WAR file to the webapps directory of Tomcat, how do I deploy it and access the application?

Answer:

Deploying WAR files in Tomcat 7 is an automatic process. Once the WAR file (e.g., sample.war) is copied or overwritten in the webapps folder, the following actions occur:

1. Automatic Deployment: Tomcat detects the new or updated WAR file and extracts it to a subfolder within webapps (e.g., sample).
2. Application URL: You can access your application from the following URL: http://localhost:8080/sample
3. Verification: Check the webapps folder for the extracted folder to confirm the deployment. If the application is not accessible or opens improperly, review the Tomcat log files (e.g., catalina.out) for potential errors related to deployment.
