Jersey2 sample rest service failing

java rest maven jersey

14,034

All Jersey dependencies should use the same version, i. e. for org.glassfish.jersey.core it should be 2.6 instead of 2.4.1.

I am trying to build a sample REST service using Jersey2:

Here are my POM dependencies:

<dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-client</artifactId>
        <version>2.4.1</version>
    </dependency>
          <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-servlet</artifactId>
        <version>2.6</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-server</artifactId>
        <version>2.6</version>
    </dependency>
    <dependency>
      <groupId>org.glassfish.jersey.bundles.repackaged</groupId>
      <artifactId>jersey-guava</artifactId>
      <version>2.6</version>
    </dependency>
  </dependencies>

And here is my web.xml:

<web-app>
  <display-name>jerseysample</display-name>
    <servlet>
        <servlet-name>Jersey REST Service</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>com.adaequare.rest.config.JerseyResourceInitializer</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey REST Service</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>
</web-app>

Here is my ResourceConfig implementation:

package com.adaequare.rest.config;

import org.glassfish.jersey.server.ResourceConfig;

public class JerseyResourceInitializer extends ResourceConfig {
    public JerseyResourceInitializer() {
        packages(true, "com.adaequare.resource");
    }
}

And finally here is my sample class:

package com.adaequare.resource;

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/hello")
public class Hello {
    @GET
    @Produces(MediaType.TEXT_HTML)
    public String sayHtmlHello(){
        return "<html><title>Hello Jersey</title><body><h1>Hello Jersey</h1></body></html>";
    }

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String sayPlainTextHello() {
        return "Hello Jersey";
    }

    // This method is called if XML is request
    @GET
    @Produces(MediaType.TEXT_XML)
    public String sayXMLHello() {
        return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
    }

}

On deploying it to Tomcat, I tried to access the following URL:

http://localhost:8080/jerseysample/rest/hello

Here is the exception I am getting:

Not able to understand what I am missing. Can some one please point out?
