本文档是基于smartforms加密PDF
1.首先我们需要去下载jar应用程序（pdfbox-app-1.8.6.jar），在SAP使用事务码CG3Z进行对jar的上传。
上传之后，我们可以在事务码AL11查看该文件，
2.使用SAP事务码SM69创建定制的外部操作系统命令
由于本次测试的系统是Linux系统，Windows的没有测试，如果上面操作不行，则采用以下方式，
3.叫basis人员在sap下载java jdk插件
PS：本示例原理参考执行CMD，命令符：java -jar D:\pdfbox-app-1.8.6.jar Encrypt -U12345 C:\Users\Administrator\Desktop\1.pdf C:\Users\Administrator\Desktop\2.pdf
java -jar ：执行jar
D:\pdfbox-app-1.8.6.jar ： jar文件路径
Encrypt ： 加密操作
-U 12345 ：加密密码
C:\Users\Administrator\Desktop\1.pdf ：文件输入路径
C:\Users\Administrator\Desktop\2.pdf : 文件输出路径
