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.

Before you begin

In the Java™ EE perspective, open your Java class in the Java editor.

Procedure

While you type your code, red underlining indicates that the validator flags any statement or value that have syntactic or usage problems.
