Building Simple Jersey Web App With Maven

I have recently configured our Hudson server to push latest Jersey snapshots to maven repository at https://maven2-repository.dev.java.net/.
Thanks to Martin Grotzke for his kind help!

I am pretty new to maven, and wanted to make sure Jersey related jars are deployed just fine and could be easily used. Following is steps to create a new Jersey based web application from scratch.
I will be using only CLI and maven.

Create a New Project Layout

At the beginning we need to create a new web project:
mvn archetype:create -DgroupId=my.example.com -DartifactId=SimpleRESTApp \\

Which should print out something like:
[INFO] Scanning for projects...
[INFO] Searching repository for plugin with prefix: 'archetype'.
[INFO] ------------------------------------------------------------------------
[INFO] Building Maven Default Project
[INFO] task-segment: [archetype:create] (aggregator-style)

[INFO] [archetype:create]

[INFO] Parameter: packageName, Value: my.example.com
[INFO] Parameter: basedir, Value: /export/home/japod/workspace/cli-jersey-app

[INFO] OldArchetype created in dir: /export/home/japod/workspace/cli-jersey-app/SimpleRESTApp
[INFO] ------------------------------------------------------------------------
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 3 seconds

And create the following subtree:

Creating a REST Resource Class

You will need to add at least one resource class.
cd SimpleRESTApp
mkdir -p src/main/java/com/example/my
vim src/main/java/com/example/my/SimpleResource.java

It could have the following content:
package com.example.my;
import javax.ws.rs.GET;
import javax.ws.rs.ProduceMime;
import javax.ws.rs.Path;
// The Java class will be hosted at the URI path "/greeting"
public class SimpleResource {
// and implement the following GET method
@GET @ProduceMime("text/plain")
public String getGreeting() {
return "Hi there";

Adding Necessary Dependencies Into Our POM

Then we will need to introduce some dependencies at our POM file,
it could be done like follows:
<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">
<name>SimpleRESTApp Maven Webapp</name>
<name>Java.net Repository for Maven</name>




We have added a new repository, tomcat plugin and jersey dependency.

Configuring Jersey Servlet Adapter

Now the last step before we can actually run the web application is to properly
configure Jersey container. I will be using a servlet adapter and the configuration
needs to be placed in our web.xml file:
vim src/main/webapp/WEB-INF/web.xml

and add the following red lines there:
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<display-name>Archetype Created Web Application</display-name><servlet>
<servlet-name>Jersey Web Application</servlet-name>
<servlet-name>Jersey Web Application</servlet-name>


Running The Application

Now to get the application running, you can simply type:
mvn tomcat:run

You should see something like:
[INFO] Scanning for projects...
[INFO] Searching repository for plugin with prefix: 'tomcat'.
[INFO] ------------------------------------------------------------------------

Testing Your REST Resource

To check your resource works, you can try:
% curl -i http://localhost:8080/SimpleRESTApp/greeting 
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Content-Type: text/plain
Transfer-Encoding: chunked

    A perfect sample. Thank you very much.

    Just in case anyone has the same problem:

    I used a different package name for my resource class. When I ran the application, Tomcat threw the following exception:

    "The ResourceConfig instance does not contain any root resource classes".

    To solve the problem, I updated web.xml to use the package of my resource class i.e.

    I don't know how I would have gotten the servlet adaptor configured without this -- maybe it should be in the docs?

    When running on windows I had to change url-pattern from url-pattern "/\*"

    to "/*" for it to work.

    The Maven repository listed at the beginning of this post is no longer active. I found the the jars in another repository here:

    I had to change the url to /* in Ubuntu for it to work. Thanks Rohit.
