基于Tomcat的solr搜索，NoHttpResponseException，所有jars都添加了

Question

我用jsp调用搜索算法来搜索Solr并得到结果。

我的jsp页面是这样的：

<table class="table table-hover">
        <tr>
            <td>Your Search Results:</td>
            <td>
                <%
                    String queryKey = request.getParameter("jobSearch");
                    ArrayList<String> resultSet = SearchSolr.queryAll(queryKey);
                    out.println(resultSet);
                %>
            </td>
        </tr>
</table>

该页面继续在以下行上给我错误：

ArrayList<String> resultSet = SearchSolr.queryAll(queryKey);

说：

java.lang.ClassNotFoundException: org.apache.http.NoHttpResponseException

异常如下所示：

    type Exception report
message An exception occurred processing JSP page /Result.jsp at line 40
description The server encountered an internal error that prevented it from fulfilling this request.

37:                 <td>
38:                     <%
39:                         String queryKey = request.getParameter("jobSearch");
40:                         ArrayList<String> resultSet = SearchSolr.queryAll(queryKey);
41:                         out.println(resultSet);
42:                     %>
43:                 </td>

我已经导入了所有必要的jar，包括httpclient，httpcore，httpmime，httpclient-cache等。

我导入的罐子如下：http://imageshack.com/a/img401/329/3we1.jpg

Answer 1

它必须将项目中的所有jar导入tomcat的lib文件夹。解决！
