网上有人说：
开发中国银行支付网关时碰到了这个问题。我想在index.jsp中导入PKCS7Tool，代码如下：
<%@ page import=”com.bocnet.common.security.PKCS7Tool” %>
运行时报错：
An error occurred at line: 9 in the generated java file
Only a type can be imported. com.bocnet.common.security.PKCS7Tool resolves to a package
意思是说只有一个类能被导入，com.bocnet.common.security.PKCS7Tool是一个包。
实际上是因为PKCS7Tool这个包没有导入java运行环境。于是我把pkcs7.jar、pkcs7-src.jar这两个包加到/usr/local/tomcat/lib/目录下，并重启tomcat，一定要确保tomcat已重启。再测试看看，程序正常运行了。
黄海的方式：fastjson-1.2.47.jar 拷贝到 /usr/local/tomcat7/lib下，然后 ./restart.sh tomcat！
<%@ page language="java" import="org.jasig.cas.client.authentication.AttributePrincipal" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

<% AttributePrincipal attributePrincipal = (AttributePrincipal)request.getUserPrincipal();
Map <String,Object>map = attributePrincipal.getAttributes();
String userId = String.valueOf(map.get("PERSONID"));
String userName = String.valueOf(map.get("USER_NAME")); out.print(userName);
