why do we need to create packages
Hello, I was wondering why do we need to create packages to keep our ActionForms, Action classes. Can't we do without creating packages. I created the .class files in WEB-INF\classes directory and gave no package names in struts-config.xml file. It gave NullPoniterException - Error creating form bean of class Test. regards, vijay. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: why do we need to create packages
That's fine. I know why packages are for. But why is it necessary to create packages to keep our ActionForm classes, Action classes. Name collision is the problem which the development team has to tackle. What if the development team decides to name classes starting with their Employee ID, probability of name collision decreases considerably. Is it strictly enforced by Struts to use packages. I dont think Java 1.5 specification speficies it explicitely to compulsarily use packages. Any pointers, Andre. Doesn't the compiler create a default package. regards, vijay.

Supposing you have two different classes with same name, you need to associate the class with a package to make clear that the class comes from a particular package...

Re: why do we need to create packages
Its not that I do not want to create any packages, I just wanted to check whether the ActionForms, Actions work without a package or not. http://marc.theaimsgroup.com/?l=tomcat-userm=104265745710637w=2 My ActionForm, Action have no packages and they are working. I made a silly mistake in struts-config.xml because of which it was not working. But how come its working. My ActionForm is instantiated by some class in the struts package. How can that class see my ActionForm which is in an anonymous package. regards, vijay.

Re: Form reset()
Suppose we have a page P1.jsp which has a corrosponding form bean,
say, TestForm. If the scope of the bean is request, then whenever we
access P1.jsp, the reset() method will be called.
If the scope is session, reset() method will be called only for the
first time, when the bean is actually loaded. On further access to
P1.jsp, reset() will not be called.
But on submission of P1.jsp, reset() is called for both the scopes.
regards,
vijay.

ActionForm objects are reused. A new one may not necessarily be
created every time a form is submitted... Struts will try and reuse
one from a pool of ActionForm objects.
If there's a free one, it calls reset() before populating it in the
controller with form values and hands it to your action.
If there's no free one, it creates a new one, calls reset(), then
populates it with form values and hands it to your Action.
You want to reset all of your ActionForm's fields to empty or
nothing, or whatever you want the default value to be if the HTTP
request doesn't include any parameters. It's a best practice to do
every field, even if all of your HTML forms have fields for each of
the attributes... and even if they do, HTTP checkboxes are only
included in parameters if they're checked... if they're unchecked then
your HTTP request won't contain that parameter.

Hi,
can someone tell exactly in which cases the ActionForm.reset() method
is called ? More specifically, when an action or a erro handler redirects
the system to a specific DispatchAction method, as showed in the code
below, dos struts reset the form ?
public class MyExceptionHandler extends ExceptionHandler {
public ActionForward execute(Exception error,
ExceptionConfig ec,
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws
ServletException {
// create action forward
ActionForward forward = new ActionForward(mapping.getPath() +
.do?action=error);
ex.printStackTrace();
if (error instanceof AuthorizationException || error instanceof
AuthenticationException)
return (mapping.findForward(logon));
return forward;
}
}

date picker (tried javawebparts but facing problem)
Hello, I need to use a data picker. I tried javawebparts but I am getting the problem of class version incompatibility for class 'CalendarTag'. I am using WAS 5.0 which is based on JDK 1.3. Is there a version of javawebparts for JDK 1.3 which I can use. Or is there any other free date picker available. regards, vijay. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
{Maybe OT} Ajax with struts
Hello, I used AJAX to fill details for a corrosponding selected value listed in a combo box. So for a particular registration number, the details of the vehicle are filled. On the onchange() event of the combo box, I am calling a JavaScript function which creates a XmlHttpRequest with the url = RegDetails.do?action=populate where action is a DispatchAction parameter. I am working in Websphere Application Developer Studio and its working great in it. But when I deploy the application in Websphere AS 5.0, the AJAX stuff does not work. Pre-population of the jsp form works great (which is also based on DispatchAction - I give http://localhost:9080/dpims/RegDetails.do?action=populate). Only the AJAX stuff does not work. I get the following error [4/11/06 12:07:14:250 IST] 5fbb0406 DispatchActio E org.apache.struts.actions.DispatchAction Request[/RegDetails] does not contain handler parameter named action I am not able to figure out the problem. regards, vijay.
Re: {Maybe OT} Ajax with struts
Yes, that was the problem. I changed the POST parameter to GET in http.open(); and its working. Keeping it POST and passing the parameters in send() does not work. Anyways, making it GET works and thats what I need. But what could be the problem? regards, vijay.

If you use POST for your XHR, you must specify request parameters in XHR.send(...) instead of appending them to action address. If you use GET, well, your URL seems ok, I would pass null in XHR.send(...) but I am not sure that this is the problem.
