问题:

I'm quite new to Java EE, and I have set up a project using NetBeans 8.0. In my EAR project, I created a JDBC DataSource and ConnectionPool which are successfully deployed to the Glassfish server upon deployment.

When I try to connect I am using JPA 2.1 with Hibernate 4.3.5 and I am using the JTA jta-data-source entry in my persistence.xml file to name the managed resource.

My persistence.xml file is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" 
        xmlns="http://xmlns.jcp.org/xml/ns/persistence" 
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xsi:schemaLocation="
            http://xmlns.jcp.org/xml/ns/persistence 
            http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd
        ">
    <persistence-unit name="my_PU" transaction-type="JTA">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <jta-data-source>jdbc/myDatasource</jta-data-source>
        <class>my.domain.model.MyModel</class>
        <exclude-unlisted-classes>false</exclude-unlisted-classes>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect" />
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.connection.datasource" value="jdbc/myDatasource" />
            <property name="hibernate.transaction.factory_class" value="org.hibernate.transaction.JTATransactionFactory"/>
            <property name="hibernate.connection.autocommit" value="true"/>
        </properties>
    </persistence-unit>
</persistence>

When I try to deploy the project, everything goes well until the Hibernate hbm2ddl kicks in, and the following error message appears:

回答1:

Looks like something is fundamentally wrong with the configuration of your connection pool within Glassfish.

Go check the properties etc., and make sure you can PING the DB from the Admin Console.



回答2:

This guidance is for integrating hibernate.4.3.5 and EJB and GlassFish.4.0 in NetBeans.8.0 IDE. Create a web project in net beans and add hibernate jar files to the project,other setting related to configuring MySql and glassfish is very simple so I do not describe in this article then create persistence.xml file as follow :

<persistence-unit name="omidashouriPU" transaction-type="Resource_Local">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
        <property name="hibernate.archive.autodetection" value="class"/>
        <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
        <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/YourSchemaName"/>
        <property name="hibernate.connection.username" value="root"/>
        <property name="hibernate.connection.password" value="yourpassword"/>
        <property name="hibernate.show_sql" value="true"/>
    </properties>
</persistence-unit>

In Your EJB class (class that annotated with @Stateless) for creating EntityManager use following syntax :

EntityManagerFactory emf = Persistence.createEntityManagerFactory("omidashouriPU");
EntityManager em = emf.createEntityManager();
em = emf.createEntityManager();
em.getTransaction().begin();
em.persist(YourEntityObject);
em.getTransaction().end();

As you Know when you are using “transaction-type="Resource_Local", you have to manage the transaction by yourself, mean that, managing of opening and closing the transaction is our responsibility.
