Structure of webapp.war:

./WEBINF

     /lib

         core.1.0-SNAPSHOT.jar

          ...

The structure of core.1.0-SNAPSHOT.jar:

./META-INF

     jpa-persistance.xml (also tried with persistence.xml)

./net

      /straininfo2

applicationContext-core.xml

The persistence.xml /jpa-persistence.xml has 4 persistence units like this:

                        <!-- Added to avoid NPE's on jboss! -->

                        <property name="hibernate.query.jpaql_strict_compliance" value="false" />

Thanks!!

I first had persistence.xml, I didn't work. Then I got this renaming from : http://community.jboss.org/blogs/mariusb/2011/07/13/spring-and-jboss-as7-part-1-getting-started     section 'spring travel'. But no changes..

I got 4 persistence units, i accidentally copied another, but it is the same (just -test- is with mor logging enabled).

my persistence is indeed in another jar file in WEB-INF/lib: the main war is the web-application and the core (persistence, entity classes, dao , logic) is in that jar.

My classes have @Entities.

I tried now with 7.1.Beta1. Because 7.1 had an error because multiple PU's were in my persistence.xml, I changed it (temporary) to only one PU:

<persistence 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"

        version="1.0">

        <!-- Configuratie van de persistence units. -->

                <persistence-unit name="straininfo2-test-xenneke">

                <provider>org.hibernate.ejb.HibernatePersistence</provider>

                <properties>

                        <property name="hibernate.archive.autodetection" value="class"/>

                        <property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver" />

                        <property name="hibernate.connection.url"

                                value="jdbc:oracle:thin:@***:1521:***" />

                        <property name="hibernate.connection.username" value="***" />

                        <property name="hibernate.connection.password" value="***" />

                        <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />

                        <!-- Echo all executed SQL to stdout -->

                        <property name="hibernate.show_sql" value="true" />

                        <property name="hibernate.format_sql" value="true" />

                        <!-- Added to avoid NPE's on jboss! -->

                        <property name="hibernate.query.jpaql_strict_compliance" value="false" />

                        <!-- JDBC connection pool (use the built-in) -->

                        <!-- <property name="hibernate.connection.pool_size" value="1" />  -->

                        <!-- JDBC connection pool (use c3p0) -->

                        <property name="hibernate.c3p0.min_size" value="3" />

                        <property name="hibernate.c3p0.max_size" value="5" />

                        <property name="hibernate.c3p0.timeout" value="900" />

                        <property name="hibernate.c3p0.max_statements" value="300" />

                        <!-- Test idle connections every two hours -->

                        <property name="hibernate.c3p0.idleTestPeriod" value="7200" />

                        <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />

                        <!-- Enable Hibernate's automatic session context management-->

                        <property name="hibernate.current_session_context_class"

                                value="thread" />

                        <!-- Disable the second-level cache -->

                        <property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider" />

                        <property name="jboss.as.jpa.providerModule" value="hibernate3-bundled" />

                </properties>

        </persistence-unit>

</persistence>

I also changed the name back to persistence.xml.

I have the server.log in attachment.

Now that persistence.xml is back in place, I see again two times the processing PersistenceUnit:

10:30:53,993 INFO  [org.jboss.jpa] (MSC service thread 1-4) JBAS011401: Read persistence.xml for straininfo2-test-xenneke

The first does some annotation binding (with some missing packets) but the second doesn't..

Thanks!!

all my entities are in the same jar

I think indeed both Jboss and spring are processing PU.

I would like to use Spring because then the same war can be used on local Jetty webservers (for development).

I started over once again with this guide (https://docs.jboss.org/author/display/AS7/Spring+applications+development+and+migration+guide)

And thus changing back to jpa-persistence so that Jboss stops processing PU. Now there's only the second processing (org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean) but still no scanning entities..

Because it worked this way with Jetty and Jboss 4, I'm still convinced its a problem between Jboss and Spring/Hibernate..

I will ask a new question with clear notice that it is a spring-jboss problem..

Thanks for helping me find the problem!
