In a EJB, there are couple of resources ( including strings) which should be injected.
But, While deploying,In the EJB configuration one can input wrong values for the resources which should be injected or forget to inject something ?

@postconstruct method will be called after the injection, but this method should not throw checked exceptions ( Honestly, don't know the reason, perhaps throwing throwing exception will make EJB deployment to stop, but that is what expected,Isn't it ?)

Is there a way to validate this, at least away to mention some resource as mandatory?

A runtime exception will stop your EJB from loading. A checked exception would be harder for the implementing container because they would have to deal with exceptions.
