    <p>My persistence xml file is like that </p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0"&gt; &lt;persistence-unit name="hibernateEbru"&gt; &lt;provider&gt;org.hibernate.ejb.HibernatePersistence&lt;/provider&gt; &lt;class&gt;com.hibernate.business_card&lt;/class&gt; &lt;properties&gt; &lt;property name="hibernate.hbm2ddl.auto" value="create" /&gt; &lt;property name="hibernate.show_sql" value="true" /&gt; &lt;property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" /&gt; &lt;property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" /&gt; &lt;property name="hibernate.connection.username" value="root" /&gt; &lt;property name="hibernate.connection.password" value="2643" /&gt; &lt;property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/BusinessDb" /&gt; &lt;/properties&gt; &lt;/persistence-unit&gt; &lt;/persistence&gt; </code></pre> <p>Then I have my code calling it with this:</p> <pre><code>public class test { public static void main(String[] args) { EntityManagerFactory emf = Persistence.createEntityManagerFactory("hibernateEbru"); EntityManager em = emf.createEntityManager(); em.getTransaction().begin(); business_card bc = new business_card(); bc.setName("Ebru"); em.persist(bc); em.getTransaction().commit(); em.close(); emf.close(); } } </code></pre> <p>I got the following error message:</p> <pre><code>Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named hibernateEbru at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:56) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:34) at com.hibernate.test.main(test.java:8) </code></pre>

    2. COGenerally this occurs because persistence.xml is not in the right place. Can you provide where this lives in your project?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
