I'm trying to use hibernate as JTA provider in glassfish. For that purpose i created sample bean
@Entity
@Table
public class BlogEntry implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue
private Long id;
@Column
private String content;
<... setters and getters ...>
}
Then i defined jdbc pool and resource in glassfish 4.1 admin panel as MySql connection. Named resource as JSFDemoJNDI. Then i created persistence.xml like this:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="myPU" transaction-type="JTA">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<jta-data-source>JSFDemoJNDI</jta-data-source>
<class>ru.windwail.BlogEntry</class>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
<property name="hibernate.archive.autodetection" value="class"/>
<property name="hibernate.transaction.jta.platform"
value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
</properties>
</persistence-unit>
And created simple servlet to test it out:
@WebServlet(name = "TestHibernateJTA", urlPatterns = {"/jta"})
public class TestJTA extends HttpServlet {
@PersistenceContext(unitName = "myPU")
EntityManager em;
@Resource
UserTransaction ut;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
BlogEntry be = new BlogEntry();
be.setContent("some content");
try {
ut.begin();
em.persist(be);
ut.commit();
} catch (Exception e) {
throw new RuntimeException(e);
}
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet SearchFacadeClient</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Done without exceptions! Yarrrr!</h1>");
out.println("<br/><a href='/'>Back</h1>");
out.println("</body>");
out.println("</html>");
} finally {
out.close();
}
}
}
So when i ran it i've got strange exception:
[2015-02-06T03:40:22.081+0300] [glassfish 4.1] [WARNING] [] [javax.enterprise.web] [tid: _ThreadID=32 _ThreadName=http-listener-1(5)] [timeMillis: 1423183222081] [levelValue: 900] [[

Then i tried to use eclipselink in persistence.xml like this:
<persistence-unit name="myPU" transaction-type="JTA">
<jta-data-source>JSFDemoJNDI</jta-data-source>
<class>ru.windwail.BlogEntry</class>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="eclipselink.ddl-generation" value="create-tables" />
</properties>
</persistence-unit>
And bam! It's working!... So problem not in code, seems its problem in hibernate jpa ? i saw few similar questions , but no solution there. ` Here is my simplest project https://github.com/icetusk/testjpa (sorry for commiting intellij idea folders :)
Maybe hibernate jpa libs made for jboss ? Seems i will use eclipselink... hope it integrates with spring well.
