    <p>I'm learning hibernate and when I run the following program, I get this message : <code>Hibernate: insert into contact (firstname, lastname, email, id) values (?, ?, ?, ?)</code> but when I check the table, nothing seems to be inserted. What's the problem here ? Clearly the statement value field is null but why?</p> <p>I have the following POJO:</p> <pre><code>public class Contact { private String firstName; private String lastName; private String email; private long id; /** * @return Email */ public String getEmail() { return email; } /** * @return First Name */ public String getFirstName() { return firstName; } /** * @return Last name */ public String getLastName() { return lastName; } /** * @param string Sets the Email */ public void setEmail(String string) { email = string; } /** * @param string Sets the First Name */ public void setFirstName(String string) { firstName = string; } /** * @param string sets the Last Name */ public void setLastName(String string) { lastName = string; } /** * @return ID Returns ID */ public long getId() { return id; } /** * @param l Sets the ID */ public void setId(long l) { id = l; } } </code></pre> <p>and below are my hibernate config and hbm files:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"&gt; &lt;hibernate-configuration&gt; &lt;session-factory&gt; &lt;property name="hibernate.connection.driver_class"&gt;com.mysql.jdbc.Driver&lt;/property&gt; &lt;property name="hibernate.connection.url"&gt;jdbc:mysql://localhost/aneesh&lt;/property&gt; &lt;property name="hibernate.connection.username"&gt;root&lt;/property&gt; &lt;property name="hibernate.connection.password"&gt;123&lt;/property&gt; &lt;property name="hibernate.connection.pool_size"&gt;10&lt;/property&gt; &lt;property name="show_sql"&gt;true&lt;/property&gt; &lt;property name="dialect"&gt;org.hibernate.dialect.MySQLDialect&lt;/property&gt; &lt;property name="hibernate.hbm2ddl.auto"&gt;update&lt;/property&gt; &lt;!-- Mapping files --&gt; &lt;mapping resource="contact.hbm.xml"/&gt; &lt;/session-factory&gt; &lt;/hibernate-configuration&gt; &lt;?xml version="1.0"?&gt; &lt;!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"&gt; &lt;hibernate-mapping&gt; &lt;class name="Contact" table="contact"&gt; &lt;id name="id" column="id" &gt; &lt;generator class="assigned"/&gt; &lt;/id&gt; &lt;property name="firstName" &gt; &lt;column name="firstname" /&gt; &lt;/property&gt; &lt;property name="lastName"&gt; &lt;column name="lastname"/&gt; &lt;/property&gt; &lt;property name="email" &gt; &lt;column name="email"/&gt; &lt;/property&gt; &lt;/class&gt; &lt;/hibernate-mapping&gt; </code></pre> <p>and here is my code to insert :</p> <pre><code>import org.hibernate.HibernateException; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; import org.hibernate.Session; public class HSession { public static void main(String[] args) { Session session = null; try{ SessionFactory sessionGet = new Configuration().configure().buildSessionFactory(); session = sessionGet.openSession(); Contact contact = new Contact(); contact.setFirstName("xyz"); contact.setLastName("zyx"); contact.setEmail("x@xmail.com"); contact.setId(20); session.save(contact); }finally{ // Actual contact insertion will happen at this step try { session.flush(); session.close(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } </code></pre>

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.
