Help with perform method
Hi: I have a class called AddUserAction which of course extends Action. In the perform method what I will do is add a record to a table in a database. The values I will add I will of course get from the form object the method takes as one of its parameters. What I would like to do is that if there is some type of error in this method, I want to be able to do a mapping.findForward(failure) and at the same time be able to include some type of error message to the user in the failure page. My failure page is probably the same form the user filled out, but the second time around I would like to display the error message. Any help with this topic is greatly appreciated.

Re: Help with perform method
What I would like to do is that if there is some type
of error in this
method, I want to be able to do a
mapping.findForward(failure) and at the
same time be able to include some type of error
message to the user in the
failure page. My failure page is probably the same
form the user filled out,
but the second time around I would like to display
the error message.
This is what ActionError, ActionErrors and html:errors/ is for.
perform(...)
{
// ... processing ...
ActionErrors errors = new ActionErrors();
ActionError err = new ActionError(error.username.taken);
errors.add(ActionErrors.GLOBAL_ERROR, err);
saveErrors(request, response);
return new ActionForward(mapping.getInput());
}
Then in the jsp page, you can simply add:
html:errors/
somewhere conspicuous to get the errors to display.

Re: Help with perform method
I sounds like you need to do three things:
1) Struts-config.xml add an input
action-mappings
action
name=StrutsTestForm
path=/StrutsTest
type=web.StrutsTestAction
input=/StrutsTest.jsp
attribute=StrutsTestForm
forward name=success path=/StrutsTest.jsp /
/action
Input is the path to return to on errors
2) In the JSP add the error tag html:errors/
3) In either the Form.Validate() method or the action Validate method create the
ActionErrors
public ActionErrors validate(ActionMapping mapping, HttpServletRequest request)
{
// Check for empties or invalids here
boolean noErrors = true;
ActionErrors ae = null;
// Soething bad detected here
if ( ae == null )
{
ae = new ActionErrors();
noErrors = false;
}
ae.add(ActionErrors.GLOBAL_ERROR, new ActionError(some property from your
resource) );
}
if ( noErrors )
{
return null; // No Errors found
}
return ae;
}
