Hi, Thank you for your response. The usage of @LocalBinding seems to help. But anyway, is it possible to intercept the decision process (the JNDI injection) in JBoss? Our use case is simple: We have a product that implements default behavior. For projects a specific implementation should be used by the product, without changing the product code! So if we use a code of | @EJB(beanName="b1") | IBean beanImpl; | and we have 2 implementations named b1 (one in the product and one project specific), we want to decide (globally by configuration) which implementation to use. bye, Georg -- www.im-consultants.at View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4188706#...
