hi,

We use an eclipse link in order to manage our data base in using PostreSQL on apache server and derby for tests.
All test have passed but when we deploy in apache TomCat 6, we get an execption : "No persistence provider for EntityManager named sadocjpa"
We have :

src/main/wepapp/META-INF/persistence xml :
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
        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_1_0.xsd ">
        <persistence-unit name="sadocjpa">
                <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
                <non-jta-data-source>java:/comp/env/ds/sadocwebappDS</non-jta-data-source>
                <class>fr.univartois.ili.sadoc.entities.Owner</class>
                <class>fr.univartois.ili.sadoc.entities.Acquisition</class>
                <class>fr.univartois.ili.sadoc.entities.Competence</class>
                <class>fr.univartois.ili.sadoc.entities.Degree</class>
                <class>fr.univartois.ili.sadoc.entities.Document</class>
                <class>fr.univartois.ili.sadoc.entities.Resume</class>

                <exclude-unlisted-classes>false</exclude-unlisted-classes>
                <properties>
                        <property name="eclipselink.ddl-generation" value="create-tables" />
                        <property name="eclipselink.ddl-generation.output-mode"
                                value="database" />
                        <property name="eclipselink.weaving" value="static" />
                        <property name="eclipselink.logging.level" value="WARNING" />
                </properties>
        </persistence-unit>
</persistence>

All dependancies were checked and we don't understand why we get this exception...
What did we forget ?

In advance thanks !

Max

The message indicates that container is unable to find the Persistance provider specified. Is the eclipselink provider in the appropriate path for the container to load it?
