[Beginners Corner] - No Persistence provider for EntityManager
by jhannoy
Hi,
I am using the following configuration:
JBoss 4.2.2 GA and EJB3/JPA.
Here follows a simple session bean and its remote interface that I've been using:
| public interface Monitor {
|
| abstract EntityManager getEm();
|
| abstract void setEm(EntityManager em);
|
| public State create(String id, float in, int r, int b);
|
| public void createState(State s);
|
| public State findById(String id);
|
| }
|
|
|
| @Stateless
| @Remote(Monitor.class)
| public class MonitorBean implements Monitor {
|
| EntityManagerFactory emf;
| @PersistenceUnit(name = "StateMonitor")
| protected EntityManager em;
|
| public MonitorBean() {
| em = emf.createEntityManager();
| }
|
| public static final String RemoteJNDIName = MonitorBean.class
| .getSimpleName()
| + "/remote";
| public static final String LocalJNDIName = MonitorBean.class
| .getSimpleName()
| + "/local";
|
| public State create(String id, float in, int r, int b) {
|
| final State state = new State(id, in, r, b, Calendar.getInstance().getTime());
|
| getEm().persist(state);
| return state;
| }
|
| public void createState(State s) {
| em.persist(s);
| }
|
| public State findById(String id) {
| return em.find(State.class, id);
| }
|
| public EntityManager getEm() {
| return em;
| }
|
| public void setEm(EntityManager em) {
| this.em = em;
| }
| }
|
As it can be seen the PU named "StateMonitor" is mentioned.
Here follows my persistence.xml file:
| <?xml version="1.0" encoding="UTF-8"?>
| <persistence version="1.0"
| xmlns="http://java.sun.com/xml/ns/persistence"
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
| xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
|
|
| <persistence-unit name="StateMonitor">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <jta-data-source>java:/OracleDS</jta-data-source>
| <mapping-file>/META-INF/orm.xml</mapping-file>
|

| <property name="hibernate.connection.username"

| <property name="hibernate.dialect"
| value="org.hibernate.dialect.Oracle10gDialect" />
| <property name="hibernate.hbm2ddl.auto" value="create" />
| <property name="hibernate.jdbc.use_streams_for_binary"
| value="false" />
| </properties>
| </persistence-unit>
| </persistence>
|
Here how my build .xml looks like:

As it can be seen I've used all the required jars in the classpath.
It seems that the server has no issues deploying the application. The following server log confirms this:

[JBoss Seam] - UTF-encoded characters not displaying
by lanoix
Hello.
An other question about character encoding... I've seen a lot of question about that, but not reflecting my problem. Problems that I've seen were &xxx wrongly displayed. The solution was to use a tool like native2... (I cannot get the name right now anymore) to translate html characters to utf-encoded characters.
I have installed the last version of JBoss tools, and I'm currently using Seam 2.0.0 GA. I'm working on a french web application, and all my accentuated characters are translated to \u... characters. So, as I've read from previous problems, it's good. But when I display the page... These characters are not displayed. Assume I have "currentTasks=T\u0089ches" in the properties file, I got a "Tches" in the page source code (Firefox, UTF-8 - IE not tried). Done using f:outputText and other components... My page are all set as UTF-8 encoding. Seam 2.0 should - I think - have no problems with UTF encoded characters, as it gives a _fr file with pre-formated messages.
What could be wrong? Did I have to do something special?
Thank you... And Merry Christmas!

[JCA/JBoss] - Re: WorkManager thread pooling

How/Where did you configure the ThreadPool ?

The JBossWorkManager is configured in $JBOSS_HOME/server/default/deploy/jbossjca-service.xml
| <mbean code="org.jboss.util.threadpool.BasicThreadPool"
| name="jboss.jca:service=WorkManagerThreadPool">
| <!-- The name that appears in thread names -->
| <attribute name="Name">WorkManager</attribute>
| <!-- The maximum amount of work in the queue -->
| <attribute name="MaximumQueueSize">1024</attribute>
| <!-- The maximum number of active threads -->
| <attribute name="MaximumPoolSize">100</attribute>
| <!-- How long to keep threads alive after their last work (default one minute) -->
| <attribute name="KeepAliveTime">60000</attribute>
| </mbean>
|
| <mbean code="org.jboss.resource.work.JBossWorkManager"
| name="jboss.jca:service=WorkManager">
| <depends optional-attribute-name="ThreadPoolName">jboss.jca:service=WorkManagerThreadPool</depends>
| <depends optional-attribute-name="XATerminatorName">jboss:service=TransactionManager</depends>
| </mbean>
You should be able to plugin custom threadpool implementation here .
But before doing so make sure that your observation regarding the BasicThreadPool is correct .
