我有這樣的託管bean：公共字段在Java中
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.sql.DataSource;
import javax.annotation.Resource;
import javax.faces.context.FacesContext;
import javax.inject.Inject;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
// or import javax.faces.bean.ManagedBean;
import org.glassfish.osgicdi.OSGiService;
@Named("ApplicationController")
@SessionScoped
public class Tab1Page implements Serializable {
public String actionString;
public Tab1Page() {
}
public static final long serialVersionUID = 254415216070877770L;
// Constants
public final static String hashKey = "tab1PageTab";
public String actApplicationControllerionString = "";
@PostConstruct
public void post() {
Format formatter;
Date date = new Date();
// Time formate 01:12:53 AM
formatter = new SimpleDateFormat("hh:mm:ss a");
tabName = formatter.format(date);
System.out.println("Tab1Page\t" + tabName + "\[email protected]");
}
@PreDestroy
public void destroy() {
Format formatter;
Date date = new Date();
// Time formate 01:12:53 AM
formatter = new SimpleDateFormat("hh:mm:ss a");
tabName = formatter.format(date);
System.out.println("Tab1Page\t" + tabName + "\[email protected]");
}
String tabName;
public String getTabName() {
return this.getClass().getName().substring(this.getClass().getName().lastIndexOf(".")) + "\t" + tabName;
}
public void setTabName(String tabName) {
this.tabName = tabName;
}
public String getActionString() {
String actionString = null;
return actionString;
}
public void setActionString(String actionString) {
this.actionString = actionString;
}
}
當我嘗試將其部署到Glassfish的我得到這個錯誤：

我不明白這是什麼錯誤表示。我修改了所有的方法是公開的，但我仍然得到這個錯誤。我如何糾正代碼？
