The Java™ EE tools
feature enhanced EJB 3.1 as-you-type validation.
While you modify the EJB 3.1 annotations in your Java class, as-you-type validation simultaneously
runs and tracks any errors that you might have in your code. The following
screen capture illustrates the as-you-type validation tool:
Using as-you-type validation
While you modify the annotations
for your EJB, as-you-type validation runs to provide you feedback
on any problems that it detects. These problems become errors when
you save them.
