Yes I recently learnt it but I always logically had this assumption: When bean A needs bean B to be injected and B's type is `prototype`, then Struts internal injection cycle always re-inject a new instance of B into A regardless if A's type is `singleton` or `prototype`. So I missed this case :( and Ach, you're right, I now can retain my high concurrent test was on JSONResult not JSONInterceptor :( Regards. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
