问题 I just read the very nice explanation of the various managed beans and their relations on Java EE 6 @javax.annotation.ManagedBean vs. @javax.inject.Named vs. @javax.faces.ManagedBean and as i face a annoying problem in my application i want to know if it is possible to control or influence the way how and when beans are started. In my Java EE application I use EJB, CDI and JSF2 as view technology. Via SPI a service from a third party is booted and it configures a job executor which starts

问题 I am using JPA 2.0 ( EclipseLink provider) with Glassfish v3.0.1 and NetBeans 6.9.1 and am NOT able to see the queries and other logging information from JPA 2.0.

问题 Ok I'm trying to do something real simple. Just to note this works fine with SessionScope. I have a datatable and when I select a row it needs to update a form that a user could edit. Every time I try and fire the row selector it comes back with this. SEVERE: Error Rendering View[/index.xhtml] java.lang.IllegalStateException: PWC3999: Cannot create a session after the response has been committed at org.apache.catalina.connector.Request.doGetSession(Request.java:2867) at org.apache.catalina

问题 Overview : I have a JEE6 project that uses Apache Maven as the build system. My project produces an EAR that contains some common JARs, some EJB modules and a WAR. The produced EAR should be deployed to JBoss AS 7 (7.1.1 for now). Best practices : If you have a web-application (like mine) and the classes for the webapp (managed beans) might be reused in other projects, it is the recommended way ( the maven way ) to package these classes into a separate JAR and make the WAR depend on this JAR.

问题 I'm working on a JavaEE application with EJB. I have an Entity called Medico which code is: @Entity public class Medico implements Serializable{ /** * */ private static final long serialVersionUID = 1L; /** * */ public Medico(String nome_medico, String morada_medico, String esp, GregorianCalendar dnasc_medico, int tel_medico) { //construtor parametrico super(); this.nome_medico = nome_medico; this.morada_medico = morada_medico; this.esp = esp; this.dnasc_medico = dnasc_medico; this.tel_medico
