Finding entity column length using JPA annotations

[Doug Slattery]

Hi folks,

I've been looking for a solution to this problem and have only found examples using mapping.

[Edit]Fat fingered something.

I need to format the output of a result set to certain column lengths based on the DDL declared length.

If for instance my entity named "USER" has:

    @Column(name = "USER_ID", length = 10)
    private String userId;

I'd like to do something like:

String.format("%-*.*s", getColumnLength("USER", "userId"), getColumnLength("USER", "userId"), user.userId);

This is a simple example of how I'd like to do it and realize there's more elbow grease involved, but hopefully it makes sense.

Anyone done anything like this before?

[Edit] Forgot to mention I'm using Hibernate.

Thanks,
-Doug

Hi, I need the same and I have found a solution that retrieves the annotation from the class in a managed bean procedure. I can't retrieve some annotations from database, even I have to define in the class. I'm work with Netbeans 6.9.1.
