Hi,
Could somebody tell me what I did wrong here.
This is very basic, nothing fancy.
This happens with Hibernate 2.02 Informix 7.1.
I let Hibernate generate everything, with nullable fields being modified from primitive to objects.

Here is the trace:

------------
The setter & getter for the field are:


public class Grille implements Serializable {

/** identifier field */
private long id;
......

private String oCode;

....

public java.lang.String getOCode() {
return this.oCode;
}

public void setOCode(java.lang.String oCode) {
this.oCode = oCode;
}

....

}


thanks in advance.
thanh.

The name of the property would be "OCode", with an initiali caps, as specified by javabeans standard.

Hi Gavin,

That fixed the problem.
Thanks Gavin.

I have a lingering doubt about this though.
Are you sure this is a javabeans convention ?

I thought that whether you name the property "oCode", or "OCode",
the getter and setter would be getOCode() and setOCode() in both cases.

Well, it is using:

java.beans.Introspector.decapitalize()

....I think it is correct....

Well,
that's true.

Then the mapping file generator is wrong then.
