Re: [ljc] Spring to compliment EJB 3.x - That's a false comparison.  Spring is a dependency-injecting container, Akka is a library providing a number of low-level concurrency primitives. Kevin W. Jun 7, 2013 12:23 PM

Re: [ljc] Daily server restarts - Actually, yes, your spot on.  Action should be driven by the measurement.  Check the air pressure and the tyre tread then take any necessary action.  Don't just put in air because the overinflated manifesto says you should. Ged B. Jun 4, 2013 8:24 PM
Re: [ljc] Daily server restarts - Personally, I would inform the customer and let them make the decision: there is this risk and it will cost you this much to prevent it. Sometimes Abraham Marín P. Jun 4, 2013 7:57 PM
Re: [ljc] Spring to compliment EJB 3.x - Hi Neil, The test is for something that then depends upon the CDI bean. Out of container that is a nuisance.  Using the test container saves a load of mocking effort. Then again, perhaps not. Ged B. Jun 4, 2013 7:41 PM

Re: [ljc] Spring to compliment EJB 3.x - If the CDI bean truly contains no functionality other than that injected by the container, then there is nothing for you to test! Any tests that you do write are only going to test the proper functioning of the container itself, which is not your job. Neil B. Jun 4, 2013 2:06 PM
Re: [ljc] Spring to compliment EJB 3.x - Kevin W. Jun 4, 2013 1:57 PM
Re: [ljc] Spring to compliment EJB 3.x - That may be oversimplifying things. With CDI the code being written becomes must more declarative in nature.  The Java without augmentation is nothing but an empty shell.  All of the behaviour is injected. Aft Ged B. Jun 4, 2013 1:44 PM

Re: [ljc] Daily server restarts - Hi Jon, The truth is that it's a far more cost effective solution.  It costs practically nothing to restart the server on a daily basis but paying developers to get things right is very expensive. I'm Ged B. Jun 4, 2013 10:42 AM
