i have simple case have rest service myservice should injected bean beanb of type beanb implements interface beanbinterface. error classic weld-001408 1 shown below:

if make declaration of beanb use concrete class beanb rather interface in myservice works (but defeats purpose of interface):
if add @produces factory method myservice construct bean works defeats purpose of letting container instantiate beans me:
@javax.enterprise.inject.produces public static beanb get() { return new beanb(); } but if @produces factory method returns interface instead won't work:
@javax.enterprise.inject.produces public static beanbinterface get() { return new beanb(); }
ejbs have weird rules interfaces exposed implemented. interfaces marked @local/@remote exposed. if want use bean interface , class need add @localbean ejb.
in short: add @local interface or @local(beanbinterface.class) beanb
