Problem with @Column annotation

Question

Hi Everybody !
I'm using JDeveloper 10.1.3.4 and I'm building an application with EJB30 and ADF with JSF.
In my entity I put:
    @Column(nullable = false, updatable = false, insertable=false)
    private Timestamp dat;
The problem is that I can put null value for this column and I can update this column also. Can somebody knows why ?
Regards,
Miljan

Apologies, I should have clarified. I think nearly every XML file in existence uses that header. The one I'm referring to should look something like this:
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
        version="2.4"> or this:
<web-app xmlns="http://java.sun.com/xml/ns/javaee"     
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
        version="2.5"> I'm not 100% sure of annotation support prior to version 2.4. Keep in mind I may be completely off the mark. That you are getting read/writes to the database implies that either you do have annotation support or that it's pulling the mappings from somewhere else.
What persistency implementation are you using?
