[ad name=”AD_INBETWEEN_POST”] While using Maven as build tool in our project, I found it very difficult to create a Dynamic Web Project which supports Maven dependencies and can execute in Eclipse! I have seen lot of people using Maven just as build tool and for local setup uses jar files in some /lib directory. I wanted to remove this dependencies on local /lib for jar files and resolve everything with Maven. My project should be a Dynamic web project with Maven dependencies enabled. Here is a simple tutorial which you can go through to create Dynamic Web Project having Maven enabled in Eclipse. This project can be used as base project and can be easily converted to most kind of project like Struts based, Spring MVC based etc.
Required Tools
For this tutorial, I assume you have following setup in your machine. 1. JDK 1.5 or above (download) 2. Eclipse 3.2 or above (download) 3. Maven 2.0 or above (download) 4. M2Eclipse Plugin (download)Step 1: Create Maven Project in Eclipse
Create a new project in Eclipse. Goto File > New > Project.. and select Maven Project from the list. Click Next. Enter “MavenWeb” as Project name and click Next. On Configuration screen, select war in Packaging and also check the checkbox for src/main/webapp. Once done, click Finish. This will create a Maven project in Eclipse.Step 2: Generate Eclipse Project with WTP
Let us convert the Maven project to Dynamic Web Project for Eclipse. For this we will use following maven command.Goto the folder where the new project is created and execute above command.Code language: HTML, XML (xml)mvn eclipse:eclipse -Dwtpversion=1.5
C:\Workspace\Test\MavenWeb>mvn eclipse:eclipse -Dwtpversion=1.5 [INFO] Scanning for projects... [INFO] Searching repository for plugin with prefix: 'eclipse'. [INFO] ------------------------------------------------------------------------ [INFO] Building Unnamed - MavenWeb:MavenWeb:war:0.0.1-SNAPSHOT [INFO] task-segment: [eclipse:eclipse] [INFO] ------------------------------------------------------------------------ [INFO] Preparing eclipse:eclipse [INFO] No goals needed for project - skipping [INFO] [eclipse:eclipse] [INFO] Adding support for WTP version 1.5. [INFO] Using Eclipse Workspace: C:\Workspace\Test [INFO] no substring wtp server match. [INFO] Using as WTP server : Apache Tomcat v5.5 [INFO] Adding default classpath container: org.eclipse.jdt.launching.JRE_CONTAINER [INFO] Not writing settings - defaults suffice [INFO] Wrote Eclipse project for "MavenWeb" to C:\Workspace\Test\MavenWeb. [INFO] [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESSFUL [INFO] ------------------------------------------------------------------------ [INFO] Total time: 4 seconds [INFO] Finished at: Wed Jul 28 13:55:09 CEST 2010 [INFO] Final Memory: 7M/30M [INFO] ------------------------------------------------------------------------That’s it. We just created Dynamic Web Project from Maven project. Now refresh the project in Eclipse.
Step 3: Change Project Facet
The above step by default set the project facet to JDK 1.4. We need to modify this and set project facet to JDK 5. Right click on MavenWeb project and select Properties (shortcut: Alt+Enter). From the Properties dialog box, select Project Facets. Now click on “Modify Project…” button and change the project facet to Java 5.0Step 4: Setting Build Path
We need to specify the Maven jar dependencies in Java Build Path of our MavenWeb project. Open Properties.. dialog box (Alt+Enter) and select Java Build Path. Click “Add Library..” button and select “Maven Managed Dependencies” and click Finish.Step 5: Hello World Servlet
Our dynamic web project with maven support is done now. Let us add a small Hello World servlet to this project and see how it works. Open pom.xml from root folder and copy following content into it. File: pom.xml<?xml version="1.0" encoding="UTF-8"?>
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>MavenWeb</groupId>
<artifactId>MavenWeb</artifactId>
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<description></description>
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.0</version>
</plugin>
</plugins>
</build>
<dependencies>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
</dependencies>
</project>
Code language: HTML, XML (xml)
Also create a servlet file HelloWorldServlet.java. We will add this servlet in net.viralpatel.maven package. File: /src/main/java/net/viralpatel/maven/HelloWorldServlet.javapackage net.viralpatel.maven;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloWorldServlet extends HttpServlet {
private static final long serialVersionUID = 1031422249396784970L;
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
out.print("Hello World from Servlet");
out.flush();
out.close();
}
}
Code language: Java (java)
Once the servlet is created, let us configure this in web.xml. Note that in our maven project no web.xml is present. We will create one at /src/main/webapp/WEB-INF/ location. File: /src/main/webapp/WEB-INF/web.xml<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<display-name>HelloWorldServlet</display-name>
<welcome-file-list>
<welcome-file>hello-world</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>HelloWorldServlet</servlet-name>
<servlet-class>
net.viralpatel.maven.HelloWorldServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorldServlet</servlet-name>
<url-pattern>/hello-world</url-pattern>
</servlet-mapping>
</web-app>
Code language: HTML, XML (xml)
All you had to do is to install “Maven Integration for WTP”.
Some time ago I created a similar post on how to create dynamic web project with Eclipse 3.5. See http://blog.goyello.com/2010/06/15/how-to-create-java-web-application-with-eclipse-wtp-and-m2eclipse/. The project can be downloaded here: http://blog.goyello.com/wp-content/uploads/2010/06/wtp-m2eclipse-demo.zip
Recently I found out that with Eclipse 3.6 and m2eclipse you could use webapp-jee5 archetype that works perfectly with WTP and Eclipse 3.6. Of course, Maven integration for WTP is required (available via m2eclipse extras update site)
thanks for sharing ;)
Thanks for sharing :) Really amazing !
how can I configure Eclipse 3.2, Maven 2.0, and M2Eclipse Plugin together? sorry im just beginner. thanks.
and how to integrate it to spring mvc3 framework?
For integrating maven + eclipse you need to download and install the m2eclipse plugin from your Eclipse IDE (help -> update software, or eclipse marketplace). AND you HAVE TO download the Maven from the link provided in the beginning of this tutorial – Required software – 3. Maven 2.0 or above. Once you have it, scroll down the maven download page and check installation instructions for you system. That should all work together.
thanks for your tutorial, but I want to notice that the version of hibernate-entitymanager is not well as far to lanch example, so to resolve this, I replace this :
org.hibernate
hibernate-entitymanager
3.3.2.ga
by this :
org.hibernate
hibernate-annotations
3.3.1.GA

How to get The Maven dependencies(the lib u are adding above) and what it will do. please guide me
A quick update (2012):
Creating Dynamic Web Project using Maven in Eclipse Indigo Service Release 2 (Build id: 20120216-1857)
1. Tools I had during this config
Note: depending on what version of Eclipse and/or M2E plugin you have, these steps may change
a. JDK 1.7
b. Eclipse, Version: Indigo Service Release 2, Build id: 20120216-1857
c. Maven 3
d. M2E Plugin installed
2. Create a new project in Eclipse
File > New > Project.. and select Maven Project from the list (webapp-javaee6). Click Next.
Enter “com.maveneclipseweb.test” as GroupId, ArtifactId “MavenEclipseWeb”, & Package “com.maveneclipseweb.test”. Click Finish.
3. Change Project Facet
From the Properties dialog box, select Project Facets. Now click on “Convert to Faceted form..” button.
Then tick Dynamic Web Module, below click on the box saying “Further configuration available” & put in Content directory “/src/main/webapp”.
Click on OK.
5. Modify the index.jsp
Add some custom text so you can verify this is your web app…
6. Run the Web App on Tomcat through Eclipse
In Eclipse, Window >> Show View >> Servers
Note: we assumed you have downloaded & installed Tomcat here
Option 1: If there is no server, Click right anywhere in that window >> New >> Server >> Tomcat 7.0 >> Next, then Select your project >> Add >> Finish
Option 2: If there is already a server, Click right >> Add/Remove, then Select your project >> Add >> Finish
Finally, Click right >> Start
7. Check this is working in your browser
Go to http://localhost:8080/MavenEclipseWeb/
You should see the custom text you entered earlier in your index.jsp page

Can we have the Change Project Facet step automated though pom file or maven command directly?
Can you please explain how to add the libraries wanted and required jars for this application.
I meant that spring and hibernate jars.
I deployed the project in Tomcat 6.0 and getting below error
Throwable occurred: java.lang.ClassNotFoundException: net.viralpatel.maven.HelloWorldServlet
I found that class file is getting created in target folder, but seems server is trying to locate in WEB-INF/classes folder. Any suggestions if am missing out something.

Hi.
I’m trying to use this example.
My requeriments is to use tomcat 5.0.18 and jdk1.5_11, so I have been testing your example.
Right now I’m using Eclipse Juno Service Release 2.
Everythings ok until I try to run on server. If I select tomcat 5.0 or tomcat 5.5 everything is unselected, but with tomcat 6.0 and above everythings ok.
Is there something in the configuration files which prevent to use this servers?
Thanks for your tutorials.
