Re: Difference between bean.field and

Yes I know that but the attributes must be public because
we are using VBSF who manage all the database access/retrieve ...
We have 2 ways for using VBSF :
- set the attributes public
- defined new get / set for all the attributes.

(we have already all the get and set but they were changed for the jsp
pages
like this :

    public String getContract_id()
    {
        // contact_id is a Integer ...

        if (contract_id == null)
           return "";
        else
           return String.valueOf(contract_id);
    }

And we have no more time to change this now ... :(

but do you have an idea why :

<INPUT TYPE="text" NAME="payment_method" VALUE="<jsp:getProperty
name="contract" property="Payment_method" />" >

don't work
and why this works :

<INPUT TYPE="text" NAME="payment_method"
VALUE="<%=contract.getPayment_method()%>" >

???
the getProperty returns "" and the getPayment_method() returns the
correct value ... ?

Thanks

Thierry

I'm not sure why it isn't working, but to be a "good" bean, your
attributes
contract_id and payment_method should be private, not public.  This
answers
your original question -- <jsp:getProperty is MUCH preferred over
beanname.propertyname because the latter does an end-run around the
bean.

Hi,

I have already tested it but without success :/

when I use
<INPUT TYPE="text" NAME="payment_method" VALUE="<jsp:getProperty
name="contract" property="payment_method" />" >

it displays nothing  in my textedit
but when I use directly contract.payment_method, it works !!!

Any ideas ? ;)

Thierry

U have the method as getPayment_method(). U have to use:

                <INPUT TYPE="text" NAME="payment_method" VALUE=
"<jsp:getProperty
                name="contract" property="Payment_method" />" >
to get the correct value. Lemme know if it doesn't work.

<jsp:getProperty name="bean" property="field" />

                Hello,

                I have a JSP page and a bean.
                When I want to display some fields of this bean for
editing,

                I used this :

                <INPUT TYPE="text" NAME="payment_method" VALUE=
"<jsp:getProperty
                name="contract" property="payment_method" />" >

                but it display nothing as if "payment_method" is null or
is
"".

                I change this code with this :

                <INPUT TYPE="text" NAME="payment_method" VALUE= "<%=
                (contract.payment_method != null) ?
contract.payment_method
: "" %>"
                SIZE=30 MAXLENGTH=40>

                and it's working !!! it displays the value of the
"payment_method" field

                Do you have an idea ?
                What is better to use ? bean.field or <jsp:getProperty
....
???


                Thanks you

                Thierry


                PS :

                A part of my bean :

                public class Contract {

                    //attributes

                    private StringBuffer error_message = null;

                    public Integer contract_id;
                    .....
                    public String payment_method;
                    .....

                    public String getPayment_method()
                    {
                        return payment_method;
                    }
                    public void setPayment_method(String
newPayment_method)
                     {
                        payment_method = newPayment_method;
                    }
