[JBoss Portal] - Re: Handling Portal/Portlet Preferences

There are more tools out there to dig through MySQL than there are for hypersonic. I'm not sure what the performance differences are, but for learning about what's going on behind the scenes, a real database was certainly easier.

[Remoting] - Re: ejb3 and NO_THROW_ON_ERROR, how can it be set.

by itsme

We have the same problem using ejb3 over http with jboss-remoting coming along with jboss4.2.0. We also get the right exception when making calls over rmi but getting UndeclaredThrowable caused WebServerError when making the same calls using http as transport. Any solutions to this? Is there a configuration needed on the server side? regards /sandor/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4064949#4064949 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4064949

[JBoss jBPM] - Re: LinkageError

Sorry, but I hope you can investigate this a little further yourself. That would be very helpful yeah, but i'm following the code to a deeper level than my knowledge, so is a bit difficult, but I will be posting here any process, perhaps with some more detail and with your knowledge, we could comprehend what is happening.

[Persistence, JBoss/CMP, Hibernate, Database] - Using JPA from web tier

by mikaelstaldal

What is the correct way of accessing a Java Persistence unit from the web tier (no EJB session beans)? I use JBoss 4.2.0. I can't get the resource injection annotations @PersistenceUnit or @PersistenceContext to work, so I have done like this: public class MyServletContextListener implements ServletContextListener { | | public void contextInitialized(ServletContextEvent sce) { | try { | EntityManagerFactory emf = Persistence.createEntityManagerFactory("myunit"); | sce.getServletContext().setAttribute(EntityManagerFactory.class.getName(), emf); | } | catch (RuntimeException e) { | throw e; | } | catch (Exception e) { | throw new RuntimeException(e); | } | } | | public void contextDestroyed(ServletContextEvent sce) { | EntityManagerFactory emf = (EntityManagerFactory)sce.getServletContext().getAttribute( | EntityManagerFactory.class.getName()); | if (emf != null) { | emf.close(); | } | } | | } | and for each web request I do like this: EntityManagerFactory emf = (EntityManagerFactory)context.getAttribute(EntityManagerFactory.class.getName()); | EntityManager em = emf.createEntityManager(); | EntityTransaction transaction = em.getTransaction(); | transaction.begin(); | | try { | // process the request here... | transaction.commit(); | } catch (Exception e) { | transaction.rollback(); | // log the error | } finally { | em.close(); | } | It seems to work, but is it thread-safe and does it give reasonable performance?
