To view the discussion, visit: http://community.jboss.org/message/595352#595352 -------------------------------------------------------------- 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.

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... -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/595352#595352] Start a new discussion in EJB3 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2029]
