HTML:Errors and Validate woes

[Andrew McLaren]

I can't seem to get errors.add to work for me inside of validate.
Here's a quick snippet of my code:

    public ActionErrors validate(ActionMapping mapping,HttpServletRequest request) {
        ActionErrors errors = new ActionErrors();
        System.out.println("beginning validate");
        if (customer.trim().equals("")) {
            System.out.println("customer failed");
            errors.add("order",new ActionMessage("missing.customer"));
            System.out.println("but do we get here?");
        }  
...
        return errors;
        }

Thanks to my fancy debugging, it appears that I am blowing up at the return errors line. I get a lovely stack dump, starting with this message:
E SRVE0026E: [Servlet Error]-[org.apache.struts.action.ActionMessage]: java.lang.ClassCastException: org.apache.struts.action.ActionMessage

I have my ApplicationResources.properties file, and as far as I can tell it's set up correctly, and is in the right place.

What am I doing wrong?

Thanks

Same error for me, Andrew.

[8/11/05 17:38:01:671 CET] 1ca22de WebGroup E SRVE0026E: [Error de servlet]-[org.apache.struts.action.ActionMessage]: java.lang.ClassCastException: org.apache.struts.action.ActionMessage

But I am filling the errors with ActionMessages correctly!
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request)
{
ActionErrors errors = new ActionErrors();

if (getNombre().trim().equals(""))
{
ActionMessage msg=new ActionMessage("errors.required","Nombre");
errors.add("msg1",msg);
}
return (errors);
}

What are we doing wrong? in fact it crashes when trying to decode the error at the <html:errors/> line.

Please help.

Hello again.
After testing a bit, I managed to make it work, have you set up your properties files correctly?

Have in mind that the message has to be correctly placed in the properties file.

resources:
my.properties
# -- my errors --
error.notallowed=No permitido.

struts-config.xml:
<message-resources parameter="resources.my" />

code:
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request)
{
ActionErrors errors = new ActionErrors();

if (getNombre().trim().equals("none"))
{

errors.add("form errors",new ActionError("error.notallowed"));


}
return (errors);
}

Worked after a server relaunch. It seems to me that you are working under Websphere, right?

Regards,

main change is:

ActionMessage error = new ActionMessage("errors.required", "Login Name");

to

ActionError error = new ActionError("errors.required", "Login Name");

ActionError is now deprecated. I had this same ClassCastException when adding an ActionMessage object to my ActionErrors object.

However, when i re-checked i found that the properties i had set in my resource file were slightly wrong.

Therefore ActionMessage will work exactly the same as ActionError as long as you have your properties file set up correctly.
