特定のテーブルにレコードを登録できない

Question

javaでJPAを使用したwebアプリケーションをmavenプロジェクトで作成しています。サーブレットからEntityManagerを使用して指定のテーブルにレコードを挿入させたいのですがエラーが発生してしまいました。

作成したのは以下のものです。

import java.io.IOException;
import java.io.InputStream;
import java.net.InetAddress;
import java.util.Properties;
import java.util.logging.Logger;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.apache.logging.log4j.LogManager;

import util.utl.OperationUserProcessing;
/**
 * Servlet implementation class ResistrationServlet
 */
public class ResistrationServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
	final static String REQUEST_URL = "http://localhost:8080/rastaurant-maven/";

	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		doPost(request, response);
	}

	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		String buildUrl = null;
		String operation_code = request.getParameter("operaiton_code");
		InetAddress addr = InetAddress.getLocalHost();

		//セッション開始する
		HttpSession session = request.getSession(true);
		String session_id = session.getId();
		String ipAddress = addr.getHostAddress();

		OperationUserProcessing oup = new OperationUserProcessing();
		oup.operation(operation_code, ipAddress, session_id);
		String getRequestUrl = prop.getProperty(operation_code);

		//利用規約同意画面を表示する
		buildUrl = REQUEST_URL + getRequestUrl;
        response.sendRedirect(buildUrl);
	}

}

package util.utl;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;

import util.entity.UserOperationHistroyEntity;

public class OperationUserProcessing {
	public void operation(String operation_code, String ipAddress, String sessionId) {
		EntityManagerFactory emf = Persistence.createEntityManagerFactory("restaurant");
		EntityManager em = emf.createEntityManager();
		EntityTransaction tx = em.getTransaction();
		UserOperationHistroyEntity uohe = new UserOperationHistroyEntity();
		tx.begin();

			uohe.setIp_address(ipAddress);
			uohe.setSession_id(sessionId);
			uohe.setOperation_code(operation_code);
			uohe.setOperation_status("Completed ");
			em.persist(uohe);


		tx.commit();
		em.close();
		emf.close();

	}

}

実行すると以下のエラーになります。

説明 The server encountered an unexpected condition that prevented it from fulfilling the request.

例外
javax.persistence.PersistenceException: No Persistence provider for EntityManager named restaurant
	

createEntityManagerFactoryはpersistence.xmlに設定したpersistence-unit nameと同じ値を設定したにもかかわらず「No Persistence provider for EntityManager named restaurant」というエラーになります。persistence.xmlの設定が良くないのでしょうか？JPAやEntity、Hibernateの設定にお詳しい方がいましたら教えていただけないでしょうか？

テーブルからエンティティを作成したところ、解決できました。
