Step 1: Install Tomcat

macOS / Linux

chmod +x setup/download-tomcat.sh
./setup/download-tomcat.sh

Windows

setup\download-tomcat.bat

This downloads Apache Tomcat 9.0.115 into the server/ directory.

Step 2: Build & Deploy

macOS / Linux

chmod +x build.sh
./build.sh

Windows

build.bat

This compiles the servlet using servlet-api.jar from Tomcat and copies the app into Tomcat's webapps/ folder.

Step 3: Run

macOS / Linux

./server/apache-tomcat-9.0.115/bin/startup.sh

Windows

server\apache-tomcat-9.0.115\bin\startup.bat

Then open your browser:

• Home page: http://localhost:8080/servlet-welcome/
• Welcome servlet: http://localhost:8080/servlet-welcome/welcome

Stop Tomcat

# macOS / Linux
./server/apache-tomcat-9.0.115/bin/shutdown.sh

# Windows
server\apache-tomcat-9.0.115\bin\shutdown.bat

Prerequisites

• Java JDK 8 or later installed and javac available on PATH
• curl (macOS/Linux) or PowerShell (Windows) for downloading Tomcat
