我已经找到了这个问题的答案,并尝试了我能找到的唯一解决方案(jmockit:Attach API的本机库在此JRE错误中不可用)
我尝试将attach.dll添加到PATH环境变量但没有成功.(C:\ Program Files\Java\jdk1.7.0_60\jre\bin\attach.dll)
还有其他建议吗？

at …我试图从一个servlet返回数据库搜索结果的ArrayList,以显示在jsp页面上.
将arraylist设置为servlet中的请求的地址,并将请求转发到jsp页面.当我尝试在jsp页面上检索它时,它会给出以下错误:
"java.util.Vector无法强制转换为java.util.ArrayList"
servlet代码:
List<Car> ResultList=SearchPartsDAO.displaySearchResults(car);
if(ResultList.size()>=1){
request.setAttribute("ResultList", ResultList);
request.getRequestDispatcher("SearchResults.jsp").forward(request, response);
}else
response.sendRedirect("NotFound.jsp");
JSP:
<body>
<%
ArrayList<Car> resultList = new ArrayList<Car>();
resultList=(ArrayList<Car>)request.getAttribute("ResultList");
%>
<%System.out.println(resultList.get(0).getCarMake());%>
