Doesn't look right. The id is the primary key - it could now be inserted
with a value of 100, always.
I can do an insert here with
@Id
@GeneratedValue(){val strategy = GenerationType.AUTO}
Still works without GeneratedValue being present. My pom dependencies are
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.3.2.GA</version>
</dependency>
<dependency>
<groupId>net.sourceforge.jtds</groupId>
<artifactId>jtds</artifactId>
<version>1.2</version>
</dependency>
Properties in persistance.xml
<properties>
<property name="hibernate.dialect"
value="org.hibernate.dialect.SQLServerDialect"/>
<property name="hibernate.connection.driver_class"
value="net.sourceforge.jtds.jdbc.Driver"/>
<property name="hibernate.connection.username" value="xx"/>
<property name="hibernate.connection.password" value="xx"/>
<property name="hibernate.connection.url"
value="jdbc:jtds:sqlserver://localhost:1433/fred"/>
<property name="hibernate.max_fetch_depth" value="3"/>
<property name="hibernate.show_sql" value="true"/>
</properties>
