最近我正在更换我的机器，不得不创建新的工作区环境。我正在使用Eclipse Kepler。我的代码在我以前的机器上运行良好，但我不知道出了什么问题，并尝试在我以前的机器上一次又一次地重新创建工作区。但是当运行Web应用程序（Primefaces，JSF，JPA 2.1 EclipseLink 2.5，tomee 7，java 6，mojarra 2.1.6）时，我在EJB中得到“无效的构造函数错误”，这在其他机器上运行良好。我的错误是：

我的EJB是：
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.ejb.LocalBean;
import javax.ejb.Stateless;
import com.magnus.model.util.FiscalYrModel;
import com.magnus.sessionejb.core.GenericDAO;
@Stateless
@LocalBean
public class FiscalYrEJB extends GenericDAO<FiscalYrModel> implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
public FiscalYrEJB() {
super(FiscalYrModel.class);
// TODO Auto-generated constructor stub
}
public List<FiscalYrModel> listAllFiscalYr(){
List<FiscalYrModel> fsList = new ArrayList<FiscalYrModel>();
fsList = findAllWithGivenCondition(FiscalYrModel.FIND_ALL_FISCAL_YR, null);
return fsList;
}
public FiscalYrModel getActiveFsYr(){
return findOneResult(FiscalYrModel.FIND_ACTIVE_FISCAL_YR, null);
}
}
我不知道是什么原因导致这个错误在我以前的机器上运行良好。我已经在我以前的机器上添加了所有必需的库以及相同版本的eclipse。 此特定错误仅发生在我新配置的计算机中。
