sessionfactory

So here is the problem. I have a common class library that holds all the repositories, domain and mapping files so the library can be reused within other web beased applications. Now within this class library there is a peiece of code that allows itself to create a session factory to be used in its repositories. Code looks something like this. private static ISessionFactory sessionFactory; private static Configuration configuration; public static Configuration Configuration() { if (configuration == null) { configuration = new Configuration().Configure(); } return configuration; } private

I have been searching for this the last few hours maybe some of you can help me. I try to achieve a reload of my mapping info in EntityManagerFactory (or SessionFactory) at runtime in spring The EntityManagerFactory is defined as follows: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceXmlLocation" value="persistence.xml" /> <property name="persistenceUnitName" value="JPAService" /> <property name="persistenceProviderClass" value="org.hibernate.ejb.HibernatePersistence"/> <property name="dataSource" ref=

I have configured composite primary key for my entity Employee as follows Employee.java: @Entity @Table(name="employee") @Proxy(lazy=false) @IdClass(EmployeeId.class) public class Employee implements Serializable { private static final long serialVersionUID = 1L; private EmployeeId employeeId; private Person person; private Branch branch; private boolean isActive; public Employee() { } @EmbeddedId @AttributeOverrides({ @AttributeOverride(name="person", column = @Column(name="person_id")), @AttributeOverride(name="branch", column = @Column(name="branch_id"))}) public EmployeeId getEmployeeId()

I have written this Hibernate object DAO, however with this approach, it is using session per update approach (which I don't think it's right). The reason why I don't think its right because I am running into problems with my User class, which contains collections that are lazily fetched. Since when retrieving each User from the DAO, the session is closed. Therefore I cannot get my collections. From time to time, it is also doing a lot of unnecessary updates to the table because the object is detached. So are there any ways of fixing my DAO, like using getCurrentSession() ? import java.util

I'm using Spring 3.1.0.RELEASE, Hibernate 4.0.1.Final, and MySQL 5.1. What is the pooled data source I should be using? I'm currently using (snippet from application context file) ... <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName"> <value>com.mysql.jdbc.Driver</value> </property> <property name="url"> <value>jdbc:mysql://localhost:3306/myproj</value> </property> <property name="username"> <value>myproj</value> </property> <property name="password"> <value>password</value> </property> </bean> but this isn't a pooled

We are working on different integrations to a swarm of identically structured legacy databases that basically cannot be altered. For this, we added an auxiliary database for holding things like meta-information, routing rules and for temporarily holding data for the legacy databases. We are mainly using NHibernate to connect to the databases. One application is a WCF Service that needs to inserts incoming data into nested tables that are really wide (dozens of columns). Obviously, performance is an issue, so I have been looking to be as economic as possible with the NHibernate transactions. At
