Annotated classes not scanned

My entities are annotated using @Entity. However, they are not recognized as entity beans if I don't define them in persistance.xml.

Here is my persistance.xml

Code:

<?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"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
             version="1.0">
   
   <persistence-unit name="MysqlDBSource" transaction-type="RESOURCE_LOCAL" >
      <class>com.hello.User</class>
      <properties>
        <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
        <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/test"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
        <property name="hibernate.connection.username" value="root"/>
        <property name="hibernate.connection.password" value="admin"/>
        <property name="hibernate.max_fetch_depth" value="3"/>
        <property name="hibernate.hbm2ddl.auto" value="update"/>
        <property name="hibernate.show_sql" value="true"/>
        <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider"/>
      </properties>
   </persistence-unit>
   
</persistence>

If I don't declare com.hello.User here, it won't be detected by hibernate. Anyone knows?

what is your packaging?

It's com.hello. Does it matter?

not the package, the packaging (jar, META-INF etc)

I Used Seam1.1.0GA to generate a eclipse project, and I run the test inside eclipse. Seam uses hibernate-all.jar by default. I've removed other files from META-INF folder and it now only contains persistence.xml. I normal simply run SeamTest. SeamTest loads a lot of things that make it too slow. That's why I need a hibernate only environment to run some database related tests.

On a test project (I am exploring Hib3 annotations), I attempted to use the Hibernate "auto discovery' of xml files and annotated classes. I did not work for me either. When I enabled more Hibernate logging for log4j, I could then look at the resulting log file and see that it was doing the auto discovery, and it was looking into a different place than my xml and annotated files are. Possibly this same thing is happening for you. I do not yet know how to get the 'auto discovery' to widen its search, and I still thought adding this reply might help you. Good luck!

in case you have not seen it already, Java Persistence With Hibernate, sample chapter 2, page 76 has some info on this.
