Hi
Gordon,
many
thanks for your fast response!
To
answer your question:
1.
For
testing I try to use eclipselink in Java SE enviroment, without
application server.
In
production there will be a apache tomcat (but not used as Java EE
server)
2.
I
think so, here is my persistence.xml
<?xml version="1.0"
encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>com.emd.testpersistence.PhaMatLoc</class>
<class>com.emd.testpersistence.PhaMatSales</class>
<class>com.emd.testpersistence.PhaMaterial</class>
<class>com.emd.testpersistence.PhaProduct</class>
<class>com.emd.testpersistence.SecVUserPrivDissolve</class>
<properties>
<property name="eclipselink.session-name"
value="my-session"/>
<property name="eclipselink.logging.level"
value="FINE"/>
<property name="eclipselink.jdbc.driver"
value="oracle.jdbc.OracleDriver"/>
<property name="eclipselink.jdbc.url" value="jdbc:oracle:thin:@d11n02p02.merck.de:1521:rc02"/>
</properties>
</persistence-unit>
with toplink essentials I didn't need to use
<provider>...</provider>
But here it doesn't seem to work.
3.
Yes, I see no other exception. And Eclipselink seems to do already
something before, I get messages like
[EPS Config]: 2008.03.11
02:34:35.782--ServerSession(471035)--Thread(Thread[main,5,main])--The
column name for element [private java.lang.String
com.emd.testpersistence.PhaMatLoc.lcomp] is being defaulted to: LCOMP.
before the exception comes.
4.
Currently
I use eclipselink-incubation-1.0M5, using eclipselink-incubation-20080228
results in the following error:
Exception in thread "main" Local

Betreff: Re:
[eclipselink-users] No Persistence provider for EntityManager - Error when
using EclipseLink
Hello Alex,
What application server are
you running in? Are you specifying the
Persistence provider in
your persistence.xml file? Is that the only
exception that you
see? Are you using the latest nightly from
EclipseLink?
