As suggested in http://galaxy.andromda.org/forum/viewtopic.php?t=5159 I tried the following changes and they worked for me:
- changed EJB Injection Definitions in "SessionBeanBase.vsl" from
    @javax.ejb.EJB
    protected ${reference.fullyQualifiedServiceRemoteInterfaceName} $stringUtils.uncapitalize(${reference.name});
  to:
    @javax.ejb.EJB
    protected ${reference.fullyQualifiedInjectedServiceInterfaceName} $stringUtils.uncapitalize(${reference.name});

- added the attribute "fullyQualifiedInjectedServiceInterfaceName" (copied from fullyQualifiedServiceRemoteInterfaceName) in the "EJB3SessionFacade" in the UML model.

- added the following code in "EJB3SessionFacadeLogicImpl":
     /**
     * @see org.andromda.cartridges.ejb3.metafacades.EJB3SessionFacadeLogic#handleGetFullyQualifiedInjectedServiceInterfaceName()
     */
    protected String handleGetFullyQualifiedInjectedServiceInterfaceName()
    {
     if (this.isViewTypeLocal() || this.isViewTypeBoth()) {
     return this.getFullyQualifiedServiceLocalInterfaceName();
     } else {
     return this.getFullyQualifiedServiceRemoteInterfaceName();
     }
    }
