I'm trying to make a web-service with Tomcat and Eclipse using jersey library. This is my service class:
package com.gontuseries.university;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
@Path("/university")
public class UniversityRestWs {
@GET
@Produces(MediaType.TEXT_HTML)
public String getHtmlUniversityInfo(){
return "<html><body>test</body></html>";
}
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getTextUniversityInfo(){
return "test";
}
}
And this is file web.xml
<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>com.gontuseries.university</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
When i test my service i get java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer I downloaded jersey from https://jersey.java.net/download.html
Can someone help me? Thanks
I got the same error -"java.lang.ClassNotFoundException : com.sun.jersey.spi.container.servlet.ServletContainer", while trying to execute restful jersey web service in tomcat from eclipse.
Following steps helped me to resolve the issue :
Correct the maven dependency to right version of dependent jars
Right click on the eclipse project -> Maven -> Update Project
Ensure in eclipse properties development assembly is configured correctly. Right click on project - Properties -> development assembly -> Add -> java build path entries -> maven dependency
We get this error because of build path issue and outdated dependency names.Latest one's start from org.glassfish and not com.sun.After replacing with latest dependencies for 2.0, You should add "Server Runtime"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 --> Build Path --> Add Library --> Server Runtime --> Apache Tomcat v7.0

The
com.sun.jersey.spi.container.servlet.ServletContainerclass is contained in the "jersey-servlet.jar" so you should put it to WEB-INF/lib along with the "jersey-server.jar".If you are using JERSEY-jaxrs-ri-2.9 version zip, Use the given below in WEB.XML file.
Are you using Jersey 2.x? If so, the
ServletContainerclass has been moved to another package. This article has some good info on how to change your web.xml when migrating from Jersey 1.7 to 2.x: https://java.net/projects/jersey/lists/users/archive/2013-06/message/91.Above provided solutions are correct but even after making these changes i was getting this error. So what I did was removed all the maven downloaded Jersey jars and update Project again with new maven dependency and that resolved my issue
