Problem

In Jersey development, hit following error message on Tomcat.


SEVERE: Servlet /RESTfulExample threw load() exception
  java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer
	
  at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1516)
  at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1361)
  //...

Here’s the Maven pom.xml


	<dependency>
		<groupId>com.sun.jersey</groupId>
		<artifactId>jersey-core</artifactId>
		<version>1.8</version>
	</dependency>

Solution

The “com.sun.jersey.spi.container.servlet.ServletContainer” is included in “jersey-server.jar“, not “jersey-core.jar“.

Actually, to develop REST service with Jersey, you just need to include “jersey-server.jar“, it will download the “jersey-core.jar” dependency automatically.


	<dependency>
		<groupId>com.sun.jersey</groupId>
		<artifactId>jersey-server</artifactId>
		<version>1.8</version>
	</dependency>
