NoSuchMehod的怪问题

我在工程中遇到一个怪问题。
    TailPriceService 继承自 BaseService。 在BaseService里面有一个deleteObjece(Objece.class, id)方法。
    将TailPriceService 注入到Actoin里面，并且在调用deleteObjece方法时抛出NoSuchMehod异常。

    我使用java反编译查看BaseService.class 的代码发现在BaseService里面有这样的方法：

    public boolean deleteObject(Class objClass, String id)
    {
        try
        {
            getHibernateTemplate().delete(getObject(objClass, id));
        }
        catch(RuntimeException e)
        {
            return false;
        }
        return true;
    }

而且在Action里面的调用：

 service.deleteObject(com/hbs/model/TailProjectItem, request.getParameter("tailProjectItemId"));

可是就是在工程运行调用的时候报错。

有低版本的jar包或者其他jar包里也有这么一个类

2 楼 xuyao 2008-12-22  

com/hbs/model/TailProjectItem是什么？另外看看有没有jar包里有别的同样的类

1 楼 qbq 2008-12-22  

com/hbs/model/TailProjectItem

你确定传的这个是个对象（Object）,而不是是个class？
