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>
can any one help me
how to connect rest api to database using hibernate
when i am deployed rest project in Tomcat i got this error com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes.
how can we write rest api for searched data from database using hibernate
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

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 servletcontainer package changed.

Thanks a lot
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,

Hi,
I am using JDK 1.5. I am not able to find the jersey servlet jar which is compatible for JDK 1.5.
Could you please help me on this.
I’ve tried this tutorial using eclipse juno + maven 3.0 + tomcat7, but I’m still get the error even the jars (jersey-server, jersey-servlet, jersey-bundle) are already there.
sorry, it seems I’ve made a typo on web.xml. And now everything works fine 🙂
thank for your tutorial.

Hi,
I am trying to implement a Hello World application using Jersey but no luck.
I am getting the following error. I am not using maven. Can you help me with a workaround?
SEVERE: Servlet /NameSearch threw load() exception
java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer
For details of how I implemented the app, please visit the link:

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.
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
Thanks Suraj. This tip fixed my problem!
It worked. Thanks
thanks it helped me a lot 🙂
Thanks!!
Thanks that worked for me.
Hey It didnt work for me as I thought it worked. I am still getting the same error. Can you help me? I am using your RESTfulExample code.
I added jersey-bundle1.12.jar and it started working.. you can try the same..
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.
i can also added to jersey bundle latest jar and jersey server after that dos’nt working ….plz tell me how it work
