ClassNotFoundException : com.sun.jersey.spi.container.servlet.ServletContainer

by

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>

Hi All,

We get this error because of build path issue. You should add “Server Runtime” libraries in Build Path.

“java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer”

Please follow below steps to resolve class not found exception.

Right click on project –> Build Path –> Java Build Path –> Add Library –> Server Runtime –> Apache Tomcat v7.0

Thanks,

Sachin G N

Hi,

I am using Jersey 1.17 and in this version, they moved the class to another Jar (jersey-servlet)

so the POM must have 3 entries now:

com.sun.jersey
jersey-core
1.17.1

com.sun.jersey
jersey-server
1.17.1

com.sun.jersey
jersey-servlet
1.17.1

and that should solve the issue for new Jersey versions.

regards,

Note that the new versions of jersey-server does not contain this class, as they have abstracted out it in jersey-servlet.
So you will have to explicitly add jersey-servlet:

com.sun.jersey
jersey-servlet
1.14
jar
compile

I am using latest jars of 2.4.1 and have added all the jars to my webinf/lib. Still I face this issue.

I am using the “Jersey JAX-RS 2.0 RI bundle” for non-maven developers.
Can someone please help? Thanks.

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

No this class is included in jersey-core but when you added to pom.xml it download the dependency jersey-core.

Yes, they moved some class, up to date solution is to add jersey-bundle1.12.jar or as name suggest jersey-servlet1.12.jar, both should work.
