首先下载了jdk 1.6.0_07之上的版本，我下载的是 1.6.0_20版本，并且下载了jce 6的文件，很小只有8K.
安装到步骤时候出现错误:
安装 ：18/29的时候,Create secure store
根据提示打开错误日志：
C:\Program Files\sapinst_instdir\NW72_DEV_ADA\SERVER\SecureStoreCreate.log
发现如下提示:

Solution:
copy
C:\Program Files\Java\jre6\lib\security 下所有文件到sap临时安装JVM目录下，
如果有提示是否需要覆盖，不要覆盖SAP原来的文件。
to
C:\Program Files\sapinst_instdir\NW72_DEV_ADA\SERVER\sapjvm\sapjvm_6\jre\lib\security
