CCE when same entity name in different PUs/apps ----------------------------------------------- Key: EJBTHREE-439 URL: https://jira.jboss.org/browse/EJBTHREE-439 Project: EJB 3.0 Issue Type: Bug Components: EJB3 Extensions Affects Versions: EJB 3.0 RC5 - PFD Environment: 4.0.4RC1 Reporter: Jens Elkner Priority: Critical If one has two applications, which have an entity with the same name (yes, the PUs have a different name, too) one gets a ClassCastException since the the proxy tries to assign the class from the other application on the client side, which is not available. E.g. app one (foolaberkram) has an entity foo.laber.kram.CatTest and app two (foobar) has an entity foo.bar.CatTest one gets the following CCE: 0 DEBUG [ main ] org.jboss.security.SecurityAssociation -
