Issue with ServletContainer in REST

Question

I am trying to write a REST service with JSON. When I am running my project in eclipse I am getting below exception.

SEVERE: Servlet [jersey-serlvet] in web application [/Ram] threw load() exception
java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer

I have checked for solution in other stackoverflow question, it's not helped me. Can anyone suggest what I missed?

POM dependencies :

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

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

Service class :

@Path("/getJson")
public class JsonExWithPojo {

    @GET
    @Path("/getStudent/{name}")
    @Produces(MediaType.APPLICATION_JSON)
    public Student getStudent(@PathParam("name") String name) {

        Student student = new Student();
        student.setStudentNo(418);
        student.setStudentName(name);
        student.setStudentAge(30);
        return student;
    }

    @GET
    @Produces("text/html")
    public Response sayHello() {
        return Response.status(200).build();
    }

}

My POJO :

public class Student {

    private int studentNo;
    private String studentName;
    private int studentAge;
    //setters and getters

}

web.xml

    <servlet>
        <servlet-name>jersey-serlvet</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.example.myproject</param-value>
        </init-param>
        <init-param>
            <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
            <param-value>true</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>jersey-serlvet</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>

Do you have jersey-core? – David Brossard Feb 23 '18 at 11:26 — David Brossard, Feb 23 '18 at 11:26

look for ServletContainer Class in jersy-server 1.8 jar file package name com.sun.jersey.spi.container.servlet if it is not present then add new jar file which contains ServletContainer class file

If you are using Jersey then you need to add @XmlrootElement at the Student class level and provide the name.
