Need help with implementing PUT annotation in my REST service

[Jack Rooney]

Hello,

I am using MAven,Hibernate 3/JPA ,Eclipse to implement a PUT method for populating a Mysql db.

Here is my POJO

import static javax.persistence.GenerationType.IDENTITY;

import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import javax.persistence.UniqueConstraint;

@Entity
@Table(name = "Person", catalog = "mydb", uniqueConstraints = {
		@UniqueConstraint(columnNames = "Person"),})
public class Person implements java.io.Serializable {

	private static final long serialVersionUID = 1L;

	private Integer id;
	private String Name;

	@Id
	@GeneratedValue(strategy = IDENTITY)
	@Column(name = "id", unique = true, nullable = false)
	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	@Column(name = "name", unique = true, nullable = false, length = 30)
	public String getName() {
		return flowName;
	}

	public void setName(String Name) {
		this.Name = Name;
	}
	
}

Here is my main class.

import javax.ws.rs.Consumes;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import org.apache.log4j.Logger;
import org.hibernate.Session;

import com.google.gson.Gson;
import com.tracker.domain.Flow;
import com.tracker.persistence.HibernateUtil;
@Path("")
public class PersonService {

	private Logger LOG = Logger.getLogger(TrackerService.class);
	
	String JsonString = "{\"name\":\"John Doe\"}";
	Gson gson = new Gson();
	Person person = gson.fromJson(JsonString,Person.class);

	@PUT
	@Path("")
	@Produces(MediaType.APPLICATION_JSON)
	@Consumes(MediaType.APPLICATION_JSON)
	public void processandSaveJson(Person person) {
	
		Session session = HibernateUtil.getSessionFactory().getCurrentSession();
		String Name = PErson.getName();
		person.setName(Name);
		session.beginTransaction();
		session.save(person);
		session.getTransaction().commit();
	}
}

Here is my Hibernate.Util.

import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;

public class HibernateUtil {
	private static final SessionFactory sessionFactory = buildSessionFactory();
	
	private static SessionFactory buildSessionFactory() {
		try {
			// Create the SessionFactory from hibernate.cfg.xml
			return new AnnotationConfiguration().configure().buildSessionFactory();

		} catch (Throwable ex) {
			// Make sure you log the exception, as it might be swallowed
			System.err.println("Initial SessionFactory creation failed." + ex);
			throw new ExceptionInInitializerError(ex);
		}
	}

	public static SessionFactory getSessionFactory() {
		return sessionFactory;
	}

	public static void shutdown() {
		// Close caches and connection pools
		getSessionFactory().close();
	}
}

Here is my SessionFactory Context Listener class

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;

import org.apache.log4j.Logger;
import org.hibernate.Session;

@WebListener
public class SessionFactoryListener implements ServletContextListener {

	private Logger LOG = Logger.getLogger(SessionFactoryListener.class);

	@Override
	public void contextInitialized(ServletContextEvent arg0) {
		if (LOG.isInfoEnabled()) {
			LOG.info("\n\tInside contextInitialized()---\n");
		}
		Session session = HibernateUtil.getSessionFactory().openSession();
	}

	@Override
	public void contextDestroyed(ServletContextEvent arg0) {
		if (LOG.isInfoEnabled()) {
			LOG.info("\n\tInside contextDestroyed()\n");
		}
		HibernateUtil.shutdown();	
	}	

}

When I try to run this using Tomcat Server, i get the following error.

type Status report

message Method Not Allowed

description The specified HTTP method is not allowed for the requested resource.

I am very new to this. Kindly let me know what I am doing wrong. I trying to insert a
record into a mysql db using the above values. Kindly help me out.

Thanks,
Jack
