ClassCastException avec une jetée et JPA

Question

Lorsque je tente d'exécuter mon application basée sur le maillot, Guice, et JPA sur la jetée (7.2.0 ou 8.0.0.M1) Je reçois l'erreur suivante, même si je ne l'utilise JNDI.

    java.lang.ClassCastException: org.eclipse.jetty.jndi.NamingContext cannot be cast to javax.sql.DataSource

Caused by:

javax.persistence.PersistenceException: java.lang.ClassCastException: org.eclipse.jetty.jndi.NamingContext cannot be cast to javax.sql.DataSource

Voici les persistence.xml correspondant

<?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="myproject" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <properties>
      <property name="javax.persistence.jdbc.url" value="jdbc:derby:memory:mydb;create=true"/>
      <property name="javax.persistence.jdbc.password" value=""/>
      <property name="javax.persistence.jdbc.driver" value="org.apache.derby.jdbc.EmbeddedDriver"/>
      <property name="javax.persistence.jdbc.user" value=""/>
      <property name="eclipselink.ddl-generation" value="create-tables"/>
    </properties>
    <non-jta-data-source/>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
  </persistence-unit>
</persistence>

Toutes les idées?

Answer 1

Vous n'avez pas besoin <non-jta-data-source/> puisque vous n'utilisez JNDI.
