RE: persistence unit can not be found during test
Thanks for the reply. I think now I figure out what goes wrong. The exception reported by the surefire is a red herring. It is indeed related to the dependency matrix issue. Orginally my hibernate entity-manager is 3.4.0 and hibernate-annotations is 3.2.1 (I can not remember exactly its version). That would not work due to compatibility issue. Hibernate page has a compatibility matrix at https://www.hibernate.org/6.html#A3. So I change to use the following configuration that solves part of problems. org.hibernate hibernate-annotations 3.3.1.GA org.hibernate hibernate-entitymanager 3.3.2.GA Also, it requires to add pkg.pathto.ClassName in persistence.xml. org.hibernate.ejb.HibernatePersistence pkg.pathto.ClassName ... So that it will scan the class which would prevent error like Caused by: java.lang.IllegalArgumentException: Unknown entity: pkg.pathto.ClassName Thanks all your help. I really appreciate it. --- On Wed, 12/8/09, Martin Gainty wrote: > From: Martin Gainty > Subject: RE: persistence unit can not be found during test > To: users@maven.apache.org > Date: Wednesday, 12 August, 2009, 8:33 PM > > why not use > oracle-toplink such as this example from > /src/conf/persistence.xml > > > transaction-type="JTA" > > oracle.toplink.essentials.PersistenceProvider > > > > jdbc/someDefinableName > > someORMap.xml > entities/Jar.jar > > ejbinaction.persistence.Category > ejbinaction.persistence.Bid > > name="toplink.ddl-generation" > value="drop-and-create-tables"/> > > > > http://www.oracle.com/technology/products/ias/toplink/JPA/essentials/toplink-jpa-extensions.html > > complete hibernate provider example is located at > http://docs.jboss.org/hibernate/stable/entitymanager/reference/en/html/configuration.html > > anyone hear of a persistence provider named "jpa"? > Martin Gainty > __ > Verzicht und Vertraulichkeitanmerkung/Note de déni et de > confidentialité > > Diese Nachricht ist vertraulich.

RE: persistence unit can not be found during test
why not use
oracle-toplink such as this example from /src/conf/persistence.xml
oracle.toplink.essentials.PersistenceProvider
jdbc/someDefinableName
someORMap.xml
entities/Jar.jar
ejbinaction.persistence.Category
ejbinaction.persistence.Bid
http://www.oracle.com/technology/products/ias/toplink/JPA/essentials/toplink-jpa-extensions.html
complete hibernate provider example is located at
http://docs.jboss.org/hibernate/stable/entitymanager/reference/en/html/configuration.html
anyone hear of a persistence provider named "jpa"?

Re: persistence unit can not be found during test
Sorry I don't understand very well. Shouldn't maven pick up persistence.xml
either specified in the src/main/resources/META-INF or
src/test/resources/META-INF? Or what command I need spcify so that when
executing `mvn test', maven will pick up persistence.xml that is copied to
target/test-classes?
Thanks for your help.
I appreciate it.

Re: persistence unit can not be found during test
your resources will be copied to /target/test-classes/ so use that, or
better, load it from the classpath, then you aren't path dependent.
