I am building a simple webapp to practice java web development. I am using Netbeans and maven and I tried to add JPA support manually adding the following file which is the standard configuration file in JPA.
src/main/resources/META-INF/persistence.xml
Also I have a simple Entity class :
package com.pet.shop.repository;
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class Animal implements Serializable{
@Id
private int id;
}
Then I tried to call my entitymanager like this :
EntityManagerFactory emf = Persistence.createEntityManagerFactory("PetShopJPA");
However I get the following error :
My pom.xm file has the following dependencies:
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.35</version>
</dependency>
<dependency>

</dependency>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
</dependencies>
My web.xml just has a servlet configuration :
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

<url-pattern>/</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>

</session-timeout>
</session-config>
</web-app>
My tomcat /lib has :
My persistence.xml is :

Please any help.
I decided used eclipse IDE and I solved the problem. Netbeans is not working in my case. Also I decided worked with EclipseLink 2.x.
