[Andromda-user] BPM4Struts - modeling decisions...

[Alexander . Gordt]

Hi all!

Sorry for repeating this question, but I still couldn't handle it to model a very simple example.
I got the following activity diagram:


-> Inital Node
-> FrontEndView: Show Login Screen
-> Transition with call-trigger(named: "check user credentials"), pointing to the controller operation "checkCredentials"; the call-trigger has two parameters for the arguments required by the operation.
-> Decision...

The controller has an operation "checkCredentials(username:String, password: String): String".


Generated source codes:

##############  Controller - checkCredentials operation ################

public abstract java.lang.String checkCredentials(ActionMapping mapping, de.objectivepartner.mda.strutshibernate.login.CheckCredentialsForm form, HttpServletRequest request, HttpServletResponse response) throws Exception;



##############  FormBean with attributes for the parameters, but it doesn't implement the CheckCredentialsForm interface  ################

public class ShowLoginScreenCheckUserCredentialsForm
    extends org.apache.struts.validator.ValidatorForm
    implements java.io.Serializable
{


##############  Action Class  ################

public final class ShowLoginScreenCheckUserCredentials extends Action

[...]

    private ActionForward checkCredentials(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception
    {
        final String value = String.valueOf(LoginControllerFactory.getLoginControllerInstance().checkCredentials(mapping, (ShowLoginScreenCheckUserCredentialsForm)form, request, response));

        if (value.equals("valid credentials"))
        {
            return mapping.findForward("login.succesful");
        }
        if (value.equals("invalid credentials"))
        {
            return mapping.findForward("login.failed");
        }

        // we take the last action in case we have an invalid return value from the controller
        return mapping.findForward("login.failed");
    }
