Hi everybody,

I plan to write a startup seam object in application scope for some business logic in JEE container.

The seam object works when the server start; say system out something which prove it is being run.

But I found that seam object cannot get entity manager, which return null value,  in either way of below declaration. (which I plan to connect database for some business logic)


1. @PersistenceContext(unitName = "XProjectDatabase")
    private EntityManager em;

2. @In(value="XProjectDatabase")
    EntityManager em;

For information, the persistence.xml is declared as below

    <persistence-unit name="XProjectDatabase">
        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
        <jta-data-source>jdbc.XDataSource</jta-data-source>   
     <properties>
         <property name="eclipselink.target-server" value="WebLogic_10"/>
         <property name="eclipselink.target-database" value="SyBase"/>
         <property name="eclipselink.logging.level" value="INFO"/>
         <property name="eclipselink.logging.logger" value="DefaultLogger"/>
     </properties>
</persistence-unit>

Can someone helps me?

Thanks
