严重: Error listenerStart
2010-12-3 9:08:07 org.apache.catalina.core.StandardContext start
严重: Context [/Java_Flex_Demo] startup failed due to previous errors我用的是Struts1，其中action代码如下：
private UserBiz biz;public void setUbiz(UserBiz ubiz) {
this.biz = ubiz;
}@SuppressWarnings("unchecked")
public ActionForward login(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
UserForm userForm = (UserForm) form;
TUser user = userForm.getUser();
List<TUser> list = biz.login(user.getUname(), user.getUpass());
if(list != null){
return mapping.findForward("success");
}else{
return mapping.findForward("error");
}
}Biz层代码：
public class UserBizImpl implements UserBiz {private BaseDAO dao;
public List login(String uname, String upass) {
String hql="from TUser u where u.uname = '" + uname + "' and u.upass = '" + upass + "'";
return dao.getUser(hql);
}
public void setDao(BaseDAO dao) {
this.dao = dao;
