Let me list out what are tools and technologies that I have used to create a web project or application using maven in Eclipse IDE.
Tools and technologies used
- IDE - Eclipse Neon
- JDK - 1.8
- Maven - 3.5.3
- Apache Tomcat - 8.5
- Servlet API - 3.1.0
Step-1
- Open Eclipse
- Click on File -> New -> Maven Project
Step-2
- Don't select a simple project as shown in below diagram
- Select default Workspace location
- Click on Next
Step-3
Select the Maven archetype as maven-archetype-webapp and click on next.Step-4
- GroupId: net.javaguides.maven-web-project
- Artifact Id: MavenWebApp
- package: net.javaguides.maven_web_project
Step-5
Now, let's test this web project by adding simple Servlet and deploy on tomcat server.
Step-6
Open pom.xml file and add servlet API dependency and maven compiler plugin as:<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>net.javaguides.maven-web-project</groupId> <artifactId>MavenWebApp</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>MavenWebApp Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet/jsp-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> </dependencies> <build> <finalName>MavenWebApp</finalName> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.5.1</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
Step-7
Now create a SimpleServlet class under net.javaguides.mavenwebapp package and write the following code in it.package net.javaguides.mavenwebapp; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * Servlet implementation class SimpleServlet */ @WebServlet("/hello") public class SimpleServlet extends HttpServlet { private static final long serialVersionUID = 1L; @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { resp.setContentType("text/plain"); resp.getWriter().write("Hello World! Maven Web Project Example."); } }
Step-8
Let's Build the project using the following maven command.- mvn clean installTo execute the about maven command in Eclipse IDE, Click on Run menu → Run Configuration.. to create a new configuration.
In Run Configuration Wizard, double-click on Maven Build and provide the configuration information (Name, Base directory and Goals) as shown in the below image.
