Also its better if you post to the struts user list rather than directly to

in if you post to the list.

Another way to do it is to create a wrapper method in your form that
does the replacing. So if you have a text property in the form, create
a textAsHTML method that return the test property with the line breaks
replaced. That could get ugly if you have lots of fields like that, so

Sounds like a good idea. I suggest that you look into using something
like ibatis to handle the caching for you, and it definately won't take
you a week to implement, even with the learning curve of ibatis.

I think why you would want to do it is pretty obvious, you need to get data from the database to display on your page,
such as a list of items. A better question is why would you not want to. That answer to that question is that it would
be better to encapsulate your database query in a Data Ac

Hello Everyone,
I am using the validator and dispatch actions and I am wonder what the
best way to do this is. Consider that I have the following method in a
dispatch action:

that
you defined in the validation.xml, e.g. 'widget-update' or 'widget-edit'
and then call the validate() method.
My main worry is that ActionMapping may not like being changed, but if
so, you could instantiate a new one.

I have an ActionForm with an int property called id. If I use the
validator "required" validation, it always passes the validation, even
if there is no request parameter called id. Is this is correct
behavior, or am I doing something wrong?
side from that, std questions about validator setup:
Is validate="true" on your ActionMapping?
Are we talking about a ValidatorForm or a ValidatorActionForm? With the
letter, you validate the Mapping name. with the former you validate the form
name?

Yes, you need to put the conn.close() in a finally, something like this
Connection conn = null;
try {

conn = ds.getConnection();

} catch(Exception ex) {
} finally {

} catch(Exception ex) {
System.err.println(ex);
}

Make your input action an error page, which just has the error and no
sensitive data and make a success forward that you only send the user to
if everything checks out.

is - is the formbean populated BEFORE the request processor
runs or after? If the form bean is populated before the method you mention,
then the request process will still be circumvented by the formbean.

I'll also create a rule in the validator to make sure that
dateOfBirthString is the right format, so the ParseException never happens.
