Maven JPA Testing

Question

Hi,
I am a maven newbie, and I have a project with two modules: EjbProject and TestProject.
The error that I have to perform the test is : javax.persistence.PersistenceException: No Persistence provider for EntityManager named testUnit
These are my codes:
persistence.xml into the Test Module
<?xml version="1.0" encoding="UTF8" ?>
<persistence 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"
             version="1.0">
      <persistence-unit name="testUnit" transaction-type="RESOURCE_LOCAL">
        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
        <jar-file>${project.build.directory}/classes</jar-file>
        <properties>
            <property name="eclipselink.jdbc.driver" value="org.hsqldb.jdbcDriver"/>
            <property name="eclipselink.jdbc.url" value="jdbc:hsqldb:mem:test"/>
            <property name="eclipselink.jdbc.user" value="sa"/>
            <property name="eclipselink.jdbc.password" value=""/>
            <property name="eclipselink.target-database"
                      value="org.eclipse.persistence.platform.database.HSQLPlatform"/>
            <property name="eclipselink.logging.level" value="OFF"/>
            <property name="eclipselink.orm.throw.exceptions" value="true"/>
            <property name="eclipselink.ddl-generation" value="drop-and-create-tables"/>
            <property name="eclipselink.ddl-generation.output-mode" value="database"/>
            <property name="hibernate.show_sql" value="${hibernate.show_sql}"/>
        </properties>
    </persistence-unit>
</persistence>the test:
public class AbstractJPATestCase extends TestCase {
    @Before
    protected void setUp() throws Exception {
        log.debug("setUp");
        try {
        emf = Persistence.createEntityManagerFactory("testUnit");
        //EntityManager em = emf.createEntityManager();
        //EntityHolder.setEM(em);
        }catch (Exception e) {
          e.printStackTrace();
          throw e;
}These are the locations:
Test Module: src/test/resources/META-INF/persistence.xml
Anyway, this is the first approximation of the solution, because what I hope to do eventually is to run the test: the file is copied persistence.xml of ejb module to test module, and modify the lines that indicate it is a jta congiruarción a local configuration.
have suggestions
Thanks!

Answer 1

A little reasoning time.
- you have a META-INF/persistence.xml file
- this persistence.xml file contains a persistence unit 'unitTest'
- yet the code still reports that this persistent unit cannot be found
My conclusion right now is that the file is actually not on the test classpath. Do you perhaps have a conflicting test resources setup in your maven pom? The file must somehow be excluded if it is not found.
