Configuration de persistence.xml en mode standalone (Java SE) avec Toplink

**verbose** · 25/09/2008, 17h45

Bonjour,

Je voudrais utiliser JPA en mode standalone avec toplink. J'ai utilisé cette doc pour renseigner le fichier persistence.xml :
https://glassfish.dev.java.net/javae...e-support.html

Voici donc mon fichier persistence.xml :

Code :

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
	version="1.0">
	<persistence-unit name="sample">
		<provider>oracle.toplink.essentials.ejb.cmp3.EntityManagerFactoryProvider</provider>
        <!-- All persistence classes must be listed -->
		<class>beans.Address</class>
		<class>beans.Person</class>
		<properties>
            <!-- Provider-specific connection properties -->
			<property name="toplink.jdbc.driver" value="<database driver>"/>
            <property name="toplink.jdbc.url" value="<database url>"/>
            <property name="toplink.jdbc.user" value="<user>"/>
            <property name="toplink.jdbc.password" value="<password>"/>
            <!-- Provider-specific settings -->
            <property name="toplink.logging.level" value="INFO"/>
        </properties>
    </persistence-unit>
</persistence>

Seulement je rencontre un erreur à l'exécution :

Il semble que l'attribut value du tag property n'admet pas le caractère "<". Or, si j'enlève les brackets, j'ai une autre exception :

Quelqu'un a-t-il déjà utilisé JPA avec Toplink ? Pouvez-vous m'aider à renseigner mon fichier persistence.xml ?

A quoi cela: <database driver>, correspond ?
Il faut fournir un nom de classe valide, celui de ton driver.

Salut,
Dans les lignes suivantes:

Code xml :

<property name="toplink.jdbc.url" value="<database url>"/>
            <property name="toplink.jdbc.user" value="<user>"/>
            <property name="toplink.jdbc.password" value="<password>"/>

Il faut remplacer les <...> par leurs valeurs correspondantes, genre:

Code code :

Sélectionner tout - Visualiser dans une fenêtre à part

<property name="toplink.jdbc.url" value="jdbc:hsqldb:file:test"/>
            <property name="toplink.jdbc.user" value="sa"/>
            <property name="toplink.jdbc.password" value=""/>

Pour une BD de type HSQL par exemple ...

Mais bien sûr, suis-je donc bête

Bon maintenant j'ai un message d'erreur comme quoi la table n'existe pas. Est-ce qu'il existe avec toplink un paramètre du même genre qu'hibernate :

Code :

<property name="hibernate.hbm2ddl.auto" value="create" />

**djo.mos** · 26/09/2008, 12h02

Code xml :

2
<property name="toplink.ddl-generation"
				value="create-tables" />

(Tu aurais pu retrouver ça avec une simple recherche

)

**verbose** · 26/09/2008, 14h02

J'obtiens toujours un message d'erreur avec le message "table not found in statement". Pourtant, les logs laissent penser que mes tables ont bien été créees malgré quelques exceptions :
