我需要使用JavaBean創建DataControl。以下是我的bean類Oracle ADF：DCA-29000：意外的異常被捕獲：java.lang.InstantiationException
package com.wip.easyrun.model.datacontrol;
public class MainMenu {
private String mainMenuItem;
public MainMenu(String mainMenuItem) {
super();
this.mainMenuItem = mainMenuItem;
}
public final void setMainMenuItem(String mainMenuItem) {
this.mainMenuItem = mainMenuItem;
}
public final String getMainMenuItem() {
return mainMenuItem;
}
}
以下是我的服務類
package com.wip.easyrun.model.datacontrol;
import java.util.ArrayList;
import java.util.List;
public class MainMenuDC {
private List<MainMenu> mainMenuList = new ArrayList<>();
public MainMenuDC(List<MainMenu> mainMenuList) {
super();
mainMenuList.add(new MainMenu("Business Health"));
mainMenuList.add(new MainMenu("Operational Health"));
mainMenuList.add(new MainMenu("Batch Job DashBoard"));
mainMenuList.add(new MainMenu("Customization Health"));
mainMenuList.add(new MainMenu("Admin"));
this.mainMenuList = mainMenuList;
}
public final void setMainMenuList(List<MainMenu> mainMenuList) {
this.mainMenuList = mainMenuList;
}
public final List<MainMenu> getMainMenuList() {
return mainMenuList;
}
}
我已創建通過MainMenuDC.java右鍵單擊數據控制。之後，我將其拖放到test.jsf。 test.jsf包含一個panelgrouplayout，在它內部我把它作爲一個listView拖動。當我運行這個頁面時，我得到以下excepiton。
