Hi,
I develop a web app which has it model classes in a separate jar that also
contains the hbm.xml files for mapping the entities. The entities are accessed
through standard JPA EntityManager. There are both query and home components
declared in components.xml:
<framework:entity-query name="subsystemList" ejbql="select s from
CaasSubsystem s" max-results="1000" />
<framework:entity-home name="subsystemHome"
entity-class="com.comptel.cs.caas.pojo.CaasSubsystem" />
Everything goes fine until I delete an entity with the home component. Then
Seam.getEntityClass gets invoked and returns null, which in turn causes the
following:
Caused by: java.lang.IllegalArgumentException: Not an entity class:
com.comptel.cs.caas.pojo.CaasSubsystem
at org.jboss.seam.Entity.forClass(Entity.java:208)
at
org.jboss.seam.persistence.PersistenceProvider.getName(PersistenceProvider.java:75)
at
org.jboss.seam.persistence.HibernatePersistenceProvider.getName(HibernatePersistenceProvider.java:246)
at
org.jboss.seam.framework.EntityHome.getEntityName(EntityHome.java:123)
at org.jboss.seam.framework.Home.getSimpleEntityName(Home.java:255)
at
org.jboss.seam.framework.Home.raiseAfterTransactionSuccessEvent(Home.java:250)
at org.jboss.seam.framework.EntityHome.remove(EntityHome.java:64)
This is because the Seam.getEntityClass checks for @javax.persisence.Entity
annotation or ejb3 xml mapping, but it does not take into account that entities
can mapped by hbm.xml files too.
I tried using hibernate-entity-home and hibernate-entity-query components , but
it did not help, but the exception occurred more often, not only after invoking
remove on the entity home component.
Annotating my classes with @Entity (which are mapped in *.hbm.xml!) helped, but
it not a correct solution, because there might be some cases when the classes
in the model package cannot be changed.
Has anyone any idea how to work this around?
Thanks,
Daniel
