org.glassfish.jersey.servlet.ServletContainer ClassNotFoundException

Question

I have been getting a ClassNotFoundException with org.glassfish.jersey.servlet.ServletContainer but it peculiarly started when I tried to start/re-start my Tomcat server (v7) with Eclipse Juno.

I am not sure what is going on. Here is the stacktrace:

Can somebody help me with this?

The problem:
java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer

This indicates that you are trying to use the Jersey 2.x servlet, but you are supplying the Jersey 1.x libs.

For Jersey 1.x you have to do like this:

<servlet>

  <servlet-name>Jersey REST Service</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>sample.hello.resources</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>

If you want to use the Jersey 2.x then you will have to supply the Jersey 2.x libs. In a maven based project you can use the following:

<dependency>

    <groupId>org.glassfish.jersey.containers</groupId>

    <artifactId>jersey-container-servlet</artifactId>

    <version>2.xx</version>

</dependency>

<!-- if you are using Jersey client specific features without the server side -->

<dependency>

    <groupId>org.glassfish.jersey.core</groupId>

    <artifactId>jersey-client</artifactId>

    <version>2.xx</version>

</dependency>

For Jersey 2.x you don’t need to set up anything in your web.xml, it is sufficient to supply a class similar to this:

import javax.ws.rs.ApplicationPath;

import javax.ws.rs.core.Application;

@ApplicationPath("rest")

public class ApplicationConfig extends Application {

}
