kali ini saya akan membuat project Java Web dengan menggunakan Apache Maven dengan template project maven-archetype-webapp. berikut adalah langkah-langkahnya:

Create Project dengan Apache Maven

mvn archetype:generate \
-DgroupId=com.maryanto.dimas.example \
-DartifactId=bootcamp-java-webapp \
-Dversion=1.0.0-release \
-DarchetypeCatalog=internal \
-DarchetypeGroupId=org.apache.maven.archetypes \
-DarchetypeArtifactId=maven-archetype-webapp

berikut adalah outputnya:

Embeded tomcat7 to run

Untuk menjalankan project, kita memerlukan Web Server seperti tomcat, undertow, jboss eap dll, dalam phase development akan lebih mudah menggunakan plugin maven yaitu tomcat7-maven-plugin berikut cara installnya:

kita edit file pom.xml dengan menambahkan plugins seperti berikut:

<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>com.maryanto.dimas.example</groupId>
    <artifactId>javaee-webapp</artifactId>
    <packaging>war</packaging>
    <version>1.0.0-release</version>
    <name>javaee-webapp-maven</name>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <endorsed.dir>${project.build.directory}/endorsed</endorsed.dir>
    </properties>

    <build>
        <finalName>${project.artifactId}</finalName>
        <!-- tambahkan dari sini -->
        <plugins>
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <compilerArguments>
                        <endorseddirs>${endorsed.dir}</endorseddirs>
                    </compilerArguments>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.2.3</version>
                <configuration>
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
            </plugin>
            <!-- sampai sini -->
        </plugins>
    </build>
</project>

Kemudian untuk menjalankan gunakan tomcat7:runseperti berikut:

mvn -DskipTests clean package tomcat7:run

Maka hasilnya seperti berikut:

tomcat running

Enabled Servlet Annotation, JSP, JSTL & Lombok

Untuk mengaktifkan fitur Annotation kita harus menambahkan dependency javax:javaee-web-api, jstl:jstl seperti berikut:

<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">

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <endorsed.dir>${project.build.directory}/endorsed</endorsed.dir>
    </properties>

    <dependencies>
        <!-- enabled jstl -->

        </dependency>
