Required field custom message

Hi,

I was trying to show a custom message to a required field

(required="true")

.
I specified the message in the

@NotNull

annotation.
Like:

@NotNull(message="Please fill username")

But I got the regular required message. Is the a way of showing a custom message in this case?

Thanks,
Guy.

You can also use your JSF component's attribute 'requiredMessage'.

Thanks,
I was still wondering if there is a way to show the custom required message directly from the @NotNull property...

AFAIK, entity level restrictions only apply when the entity is being persisted/updated.

Hi Aldo,

Are you sure about that?
When I use @Length validation or @Email validation I get the error messages on the UI before persisting the object.

Your observation is correct. I think I made a misasumption based on what I thought @NotNull did. Anyways, thanks for pointing this out.

Regarding your first question, @Length may be more suitable to your needs in this case, due to the fact that JSF is passing a zero lenght string instead of a null.
