Question

While I was working on creating a new stripes action, I found the following error on a log file.

**net.sourceforge.stripes.exception.StripesServletException: ***Could not create instance of ActionBean type*** [site.person.inspector.finaid.budget.ManageSession].**

Below are the classes that I am working for right now.

@UrlBinding("/person/inspect/finaid/budget/manage-session-budget.page")
public class ManageSession extends AbstractAidApplicantYearSessionTab{
//The class AbstractAidApplicantYearSessionTab has a hierarchy and the last one extends from UIAction
    private static final String MANAGE_JSP_FILE="person/inspect/finaid/budget/manage-session-budget.jsp"  ;
    @Override
    @DefaultHandler
    public Resolution show() {
        return new MauiForwardResolution(MANAGE_JSP_FILE);
    }

    public ManageSession(PersonInspectorAction personInspector, String group, String title) {
           super(personInspector, group, title);
       }

}


@UrlBinding("/person/inspect/finaid/budget/cost-of-attendance.page")

public class CostOfAttendanceTab extends AbstractAidApplicantTab {

public String getViewSessionUrl() {
        return "/person/inspect/finaid/budget/manage-session-budget.page";
    }

public CostOfAttendanceTab(PersonInspectorAction personInspector, String group, String     title) {
    super(personInspector, group, title);
}


}

What I am trying to do is when you click a link I calls the getViewSessionUrl (i.e actionBean.viewSessionUrl). which in turn takes you to the manage-session-budget.page (i.e class ManageSession)… In that class I have a default resolution called show().. which forwards you to the manage-session-budget.jsp …. but I don’t know why it is not getting that jsp file or sth is wrong with the ManageSession page …

Do you have any thought?

Answer 1

The action bean class (ManageSession), doesn't have a no-arg constructor, so Stripes can't create an instance of this class.
