Have custom function in a EJB

I've a integer field in the database, that represent a status. I want to display a text instead of this textField. So I've added a function called

public getTextStatus(){

But when I do this, I've this error:
Caused by: javax.el.PropertyNotFoundException: The class 'datamodel.Deal' does not have the property 'TextStatus'.

After this I've tried to add a fake EJB field and I've now this error.
Internal Exception: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'TEXTSTATUS' in 'field list'

I understand theses errors but I don't know how to bypass them.

Why generating this in the EJB? Because I need to display it in a table, (rich:datatable), and I was thinking it was the easier way.

Have you an idea?

Did you add this function to your interface class?

Not really, because the EJB itself doesn't have an interface.

I've added this function to the entity, and after I use a session bean to access it(and this session bean has interfaces)

If you want to add a getter to you EJB class that should not be persisted to the database you should add the @Transient annotation.

public String getTextStatus() {

In you JSF page, did you use TextStatus or textStatus? The first letter of the property should be lower case in your JSF pages, and the error displays a capital T.

Can you post some code?

When I add the @Transient before my getter, I got one error from netbeans, saying me the "There is no ID defined for this entity hierarchy"

I don't really know what changed, but now, without properties, only with a getter, it works.

It's maybe the Maj problem as you said. Thanks you for your help.

Was your property private or public?

If you have a public property, i think it will also be available and persisted.

I wasn't having a property, only getters and setters,

In fact the getter only take a String in an array, depending of the value of a persistent field.
