虽然我正在创建新的条纹操作，但我在日志文件中发现了以下错误。net.sourceforge.stripes.exception.StripesServletException：无法创建ActionBean类型的实例

下面是我工作的，现在的类。
@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);
}
}
我所试图做的是，当你点击一个链接我调用getViewSessionUrl（即actionBean.viewSessionUrl）。然后转到manage-session-budget.page（即ManageSession类）...在该类中，我有一个名为show（）的默认分辨率，它将您转发到manage-session-budget.jsp ...。但我不知道为什么它没有得到该jsp文件或者与ManageSession页面有什么不同......
你有什么想法吗？
好吧。你是对的'ManageSession'没有没有参数的构造函数。所以其他课程如“CostOfAttendance”也很好。即使我试图在ManageSession中放置一个默认构造函数，并且它有一个编译时错误，它表示site.person.inspector.finaid.AbstractAidApplicantYearSessionTab（ManageSession的父级）中没有可用的默认构造函数。当我在AbstractAidApplicantYearSessionTab中做同样的事情时，它会一直指向父类，等等。我无权更改除ManageSession之外的其他课程。我该怎么办？ – WowBow 2012-01-17 14:24:00
CostOfAttendanceTab类具有无参数构造函数，因为它没有任何构造函数，在这种情况下，Java编译器为您创建一个只调用'super（）'的构造函数。无参数构造函数**必须调用超级构造函数作为其第一条指令。如果超类没有无参数构造函数，那么必须明确调用另一个构造函数：'public ManageSession（）{super（null，null，null）; // ...}'。请参阅http://docs.oracle.com/javase/tutorial/java/javaOO/constructors.html – 2012-01-17 14:29:54
我很抱歉。 CostOfAttendanceTab中已经有一个构造函数。我编辑了我的问题。 public CostOfAttendanceTab（PersonInspectorAction personInspector，String group，String title）super（personInspector，group，title）; } – WowBow 2012-01-17 14:42:16
