RESTful web service with Jersey and Maven

June 5, 2015September 8, 2020 maltesander

In this tutorial we will create a simple RESTful web service with Jersey and Maven. The example code is available on Github.

1. Requirements

Eclipse EE 4.4.2 (important, make sure to use the EE version, otherwise you cannot adapt the Project Facets later on)
Apache Maven 3.3.3
M2E – useful Maven plugin for Eclipse
Tomcat 8
JDK 8

You can use other versions for Tomcat and the JDK, just make sure you adapt everything accordingly. The safest way is to use the same versions though.

2. Installation

Assuming JDK, Eclipse, Maven and Tomcat are installed correctly.

If you need help with installing either Maven or Tomcat, check out these tutorials.

If the preconditions are fullfiled, we continue with installing M2E. This Eclipse plugin helps us with creating and building Maven projects automatically.

In Eclipse go to Help ⇒ Install new Software ⇒ Add and use the location: http://download.eclipse.org/technology/m2e/releases
Enter some name and the location of the package
Press ok and click through the following Forms with Next.
Select the required Packages
After download and restarting Eclipse, M2E is successfully installed.

3. Create Maven Project

In the Eclipse Project Explorer (on the left hand side) right click and select new project. Search for Maven and select Maven Project. Click Next.
Search for “maven” and select Maven Project
Keep the properties in the next window and click Next.
Keep the predefined properties and click Next
In the following window select Maven archetype maven-archetype-webapp and click Next.
Select Maven arcehtype maven-archetype-webapp
Enter a group Id and artifact Id and click Next. Eclipse will generate the project structure.
Enter group and artifact Id
You will see the following project structure in the Project Explorer:
Project Explorer after creating Maven project
You probably see javax.servlet.http.HttpServlet” was not found on the Java Build Path.
You have to add the Apache Tomcat servlet to the Java Build Path. Please follow this tutorial on how to integrate the Apache Tomcat dependencies into your project.

4. Adapt the pom.xml

Open the pom.xml in your root folder and replace the content:

<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.tutorialacademy.rest</groupId>
	<artifactId>helloworld</artifactId>
	<packaging>war</packaging>
	<version>0.0.1-SNAPSHOT</version>
	<name>helloworld Maven Webapp</name>
	<url>http://maven.apache.org</url>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>

	<repositories>
		<repository>
			<id>maven2-repository.java.net</id>
			<name>Java.net Repository for Maven</name>
			<url>http://download.java.net/maven/2/</url>
			<layout>default</layout>
		</repository>
	</repositories>

	<dependencies>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>3.8.1</version>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>com.sun.jersey</groupId>
			<artifactId>jersey-server</artifactId>
			<version>1.9</version>
		</dependency>
	</dependencies>

	<build>
		<sourceDirectory>src/main/java</sourceDirectory>

		<plugins>

			<plugin>
				<artifactId>maven-war-plugin</artifactId>
				<version>2.4</version>
				<configuration>
					<warSourceDirectory>WebContent</warSourceDirectory>
					<failOnMissingWebXml>false</failOnMissingWebXml>
				</configuration>
			</plugin>

			<plugin>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>3.1</version>
				<configuration>
					<source>1.8</source>
					<target>1.8</target>
				</configuration>
			</plugin>

		</plugins>

	</build>
	
</project>

Now some explanation for the pom.xml
- <dependencies>: Libraries or jar files that are required. After a Maven project update (which we will perform later), Maven will download these libraries and add them to the Java Build Path.
- <sourceDirectory>: Directory where Maven will find our packages and Java classes.
- <plugins>: Addiontal information for Maven, e.g. compiler version

5. Adapt the web.xml

Open the web.xml file located in your WEB-INF folder (src ⇒ main ⇒ webapp ⇒ WEB-INF). You have to specify the servlet container, define start pages like index.php and locate the web service packages in your project.

Replace the the web.xml with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://xmlns.jcp.org/xml/ns/javaee"
	xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
	id="WebApp_ID" version="3.1">

	<display-name>helloworld</display-name>

	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>

	<servlet>
		<servlet-name>helloworld</servlet-name>
		<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
		<init-param>
			<param-name>com.sun.jersey.config.property.packages</param-name>
			<param-value>com.tutorialacademy.rest</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>helloworld</servlet-name>
		<url-pattern>/rest/*</url-pattern>
	</servlet-mapping>

</web-app>

The welcome-file-list specifies which files are called per default, if available. The servlet and servlet-mapping specify the servlet container and the path to the servlet container. You can adapt display-name and servlet-name according to your requirements.
Important: If you use different project or package etc., make sure the paths are adapted correctly. Especially <param-value>com.tutorialacademy.rest</param-value>.

6. Create a web service class

Right click src/main and create a new folder called java
Right click the new src/main/java source folder (below Java Resources), click on New ⇒ Package. We call it com.tutorialacademy.rest.
Right click the new package, click on New ⇒ Class. We call it RESTfulHelloWorld.

Copy the following code into the new class

package com.tutorialacademy.rest;

import java.util.Date;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;

@Path("/")
public class RESTfulHelloWorld 
{
	@GET
	@Produces("text/html")
	public Response getStartingPage()
	{
		String output = "<h1>Hello World!<h1>" +
				"<p>RESTful Service is running ... <br>Ping @ " + new Date().toString() + "</p<br>";
		return Response.status(200).entity(output).build();
	}
}

Ignore the code and import errors for now, we have to adapt the Maven project to retrieve missing dependencies.

7. Adapt the Maven project

You should adapt the JDK and Dynamic Web Module Version in the Project Facets. Therefore, right click on your project and select Properties. Select Project Facets.
Adapt the Dynamic Web Module to version 3.1
We adapted the JDK to 1.8. You need at least JDK 1.7 to switch to the latest Dynamic Web Module version 3.1. If you are unfamiliar with this topic, please use the same versions to avoid complicating errors.
You may not be able to adapt the Dynamic Web Module version. Deselect it, adapt the JDK version to 1.8 or 1.7 and hit apply. Select the desired Dynamic Web Module version and click apply again.
You can select the JAX RS 1.1 as well. Anyways, this will adapt automatically after the update of the project in the next chapter.
Depending on your selected version, Errors and Warnings may differ from this tutorial.

8. Update the Maven project

Right click the project and select Maven ⇒ Update Project. You can press ALT + F5 as shortcut.
Select your project and click OK
Now Maven will download missing dependencies, adapt the project structure according to the pom.xml.
Important: Copy your web.xml into WebContent/WEB-INF folder. You can delete the index.js.
Your project structure should now look similar to this:
Compare if you have a similar project structure

9. Run Maven Build

Right click your project and select Run As:
Select run as Maven Build (6)
Add “clean install“ to the goals and click Apply and then Run:
Clean the project and rebuild it
Now Maven generated a war file in the target folder:
Check if you have generated a war file and or error messages in the console
If you do not see any errors but “[INFO] BUILD SUCCESS”, we can start an run our project on the Tomcat server.

10. Run the RESTful project on Server

You can use the internal Eclipse web browser and Tomcat runtime or deploy it yourself.

Deployment in Eclipse:
1. Right click your project and select Run As ⇒ Run on Server
2. Eclipse will open the internal web browser, but we have to adapt the URL to “http://localhost:8080/helloworld/rest/”
  You should see the Hello World message in your browser
Deployment in Tomcat directly:
1. Copy the “helloworld-0.0.1-SNAPSHOT.war” file into your %CATALINA_HOME%/webapps folder.
2. Go to the command line (Winkey + R) and enter: %CATALINA_HOME%\bin\startup.bat
3. Enter “http://localhost:8080/helloworld-0.0.1-SNAPSHOT/rest/” in your web browser:
  Check if you see the Hello World message
Now you created a RESTful web service using Maven and Tomcat.

If you have errors, exceptions or other problems feel free to comment and ask.

hey,

Thanks for the tutorial. I am having some issues running the service though, I always receive a 404 error when i hit the endpoint.

I’m using eclipse neon, jdk8, tomcat 8.5.

Here is my tomcat console output –
http://pastie.org/pastes/10976623

Here is my java resource class –
http://pastie.org/pastes/10976618

Here is my web.xml file –
http://pastie.org/10976693

Here is my pom.xml –
http://pastie.org/10976695

I have also tried fiddling with the tomcat deploy destination (between webapps and wtpwebapps) but that didnt help. The webapps folder has a ‘form-builder’ dir in it and as you can see from the tomcat trace, it seems to recognise & expand it (when I hit localhost).

Can you see where I have gone wrong (i’m hoping I’ve made a stupid error).

cheers
David

Hi,

I find the tutorial very useful; I am used to create Restful services in Eclipse with Jersey but without Maven. Now I want to incroporate the use of Maven. I installed Eclipse Neon JavaEE (Maven included) and Tomcat 8.

My problem is in the step “Update the Maven project”; JDK 1.8 and Jersey 1.1 are ok, but when selecting Dynamic Web Module to version 3.1 it raises the error “Cannot change version of the project facet Dynamic Web Module to 3.1” (it only accepts version 2.3)

Any help is really welcomed.
Thanks!!

  Hi, sorry for the late answer.
  
  Please check chapter “7. Adapt the Maven project” bullet 3.
  
  It should work if you deselect it, hit apply and then reselect the 3.1 Web Module.

I have done everything correctly,I think.Yet I get a HTTP 404 error.Could you please help ?
type Status report

message /helloworld/rest/

description The requested resource is not available.
Does this mean that my server is functional but I cannot access the resource ? And if so,why ?

  Hey,
  
  yes 404 means server is running but cannot find the requested resource.
  Did you adapt the web.xml? It´s most likely a path / configuration problem.
  Please post more information / logs / web.xml etc. otherwise its hard to help properly.

      Hey,
      how do you deploy the war file? Do you use Eclipse or deploy it directly in tomcat?
      From your log it seems that no .war file is deployed to the tomcat:

      That is the end from my startup log. Tomcat scans for the root resource class and deploys the war files located in the webapps folder.
      Thats why you get the 404, because there is nothing mapped to the path your are calling.
      
      If you directly copied the pom.xml and web.xml please check your folder structure. Is your package name com.tutorialacademy.rest etc.?
      
      I can send you the war file or project via email if you like, then you try if that works and compare.

        Hi! I noticed that my project wasi n src/{Project-name}/java,so I deleted it and made a fresh one in src/ain/Java. I am using Eclipse to deploy the .war file.But now on accessing http://localhost:9999/helloworld/rest,I get the HTTP Status 500.Below is my log :

        To my understanding,this happens because no class can be found to be executed as a web service.How do I fix this ?
        Also,you mention the .war file being in webapps folder.My war file is at workspace/helloworld/target.Your help is greatly appreciated.

        2. Make sure the class is compiled properly (check if it is available in workspace/helloworld/target/classes/com/tutorialacademy/rest as .class file and finally in the warfile itself: workspace/helloworld/target/helloworld-0.0.1-SNAPSHOT/WEB-INF/classes/com/tutorialacademy/rest)
        3. Make sure you have the entry point annotation in the main class (RESTfulHelloWorld: @Path(“/”) )
        
        Do a maven project clean and rebuild to remove artefacts.
        
        For now it doesnt work because there is something messed up with your folders/packages and the config path. Please have a look at the screenshots of my eclipse project to make sure your path configuration etc. is correct, or adapt accordingly.
        
        Your warfile is correctly placed if you deploy from eclipse. Anyhow, in production you will deploy a warfile to tomcat directly (which you copy into the webapps folder of tomcat).
        
        Hope this helps.

  “Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS011232: Une seule classe Application JAX-RS trouvée”
  
  Please check that no other JAX-RS implementation is listed in the classpath. Can you post your pom file / classpath?
