Struts: How do I validate data from an edit form?

    In my Struts app - after submit - I want to validate fields that were
    filled with values from a database beforehand. To fill the fields with
    the old values I write the existing data into a bean and use it in my
    JSP as follows:

    <jsp:useBean id="formData" scope="request" class=""/>

    <html:text name="formData" property="test"/>

    So far so good.

    When a validation error occurs the user is redirected to the same JSP.

    The problem now is that the fields are empty because the bean defined
    in the JSP doesn't exist anymore. In fact I actually don't want this
    bean to be used. The form-bean which is containing the new data should
    be used.

    How can I acchieve that?

    Does your bean have session scope?
