Hi
i am new to JBoss and EJBs in general so plase help :)
Every time i try to deploy my application i get erros indicateing that the persistance
unit cannot be found:
* UNRESOLVED Demands
'persistence.unit:unitName=EsbMonitorEAR-0.0.1-SNAPSHOT.ear/#EsbMonitorPU' **
* 14:51:40,882 ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error
installing to Start:
name=*persistence.unit:unitName=EsbMonitorEAR-0.0.1-SNAPSHOT.ear/#EsbMonitorPU*
state=Create: javax.persistence.PersistenceException: [PersistenceUnit: EsbMonitorPU]
class or package not found
and the following kind of demands:
* and demands:
14:51:27,287 INFO [org.jboss.ejb3.deployers.JBossASKernel]
persistence.unit:unitName=*EsbMonitorEAR-0.0.1-SNAPSHOT.ear/#EsbMonitorPU*; Required:
Described
where does this name come from?
The persistence.xml (i had to place it in the META-INF of the EAR-file) looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
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_2_0.xsd">
<persistence-unit name="EsbMonitorPU" transaction-type="JTA">
<jta-data-source>java:jdbc/esb_monitor_dev</jta-data-source>
<class>...</class>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="eclipselink.ddl-generation"
value="create-tables"/>
<property name="hibernate.hbm2ddl.auto" value="update" />
<property name="jboss.entity.manager.jndi.name"
value="java:/EsbMonitorPU"/>
<property name="jboss.entity.manager.factory.jndi.name"
value="java:/EsbMonitorPUFactory"/>
</properties>
</persistence-unit>
</persistence>
This is the DS-File wich is localed in the server\default\deploy directory:
<datasources>
<local-tx-datasource>
<!-- The jndi name of the DataSource, it is prefixed with java:/ -->
<!-- Datasources are not available outside the virtual machine -->
<jndi-name>jdbc/esb_monitor_dev</jndi-name>
<!-- for in-process persistent db, saved when jboss stops. The
org.jboss.jdbc.DerbyDatabase mbean is necessary for properly db shutdown -->
<connection-url>jdbc:derby://localhost:3301/esb_monitor_dev;create=true</connection-url>
<!-- The driver class -->
<driver-class>org.apache.derby.jdbc.ClientDriver</driver-class>
<!-- The login and password -->
<user-name>ESB</user-name>
<password>sa</password>
<!-- The minimum connections in a pool/sub-pool. Pools are lazily constructed on
first use -->
<min-pool-size>5</min-pool-size>
<!-- The maximum connections in a pool/sub-pool -->
<max-pool-size>20</max-pool-size>
<!-- The time before an unused connection is destroyed -->
<idle-timeout-minutes>5</idle-timeout-minutes>
<!-- Whether to check all statements are closed when the connection is returned
to the pool,
this is a debugging feature that should be turned off in production -->
<track-statements/>
<!-- This mbean can be used when using in process persistent derby -->
</local-tx-datasource>
</datasources>
And this is how i refer to the PUs:
@PersistenceUnit(unitName="EsbMonitorPU")
private EntityManagerFactory factory;
@PersistenceContext(unitName = "EsbMonitorPU")
private EntityManager em;
protected final EntityManager getEntityManager() {
if (em == null) {
em = factory.createEntityManager();
}
return em;
}
I assembled all this code from various sources in the iNet but nothing works so far.
Any Ideas? How ist this courios
"*EsbMonitorEAR-0.0.1-SNAPSHOT.ear/#EsbMonitorPU*" name assembled? Is my Maven
configuration responsible for that? If so i dont understand how...
I use JBoss 6.0.0Final
Thank you
BTW: If i run it directly from Eclipse, everything works fine...
