如何安装SAP JCo3

本文以SAP JCo_3.04为例，阐述如何安装SAP JCO。

JCo有32位和64为之分，那么我们将如何选择JCo的位数呢？很简单，32位的JVM选择32位的JCO,

64位的JVM选择64位的JCO, 在windows环境，选择相应的sapjco3.dll, Unix和Linux环境选择合适

的sapjco3.so 。

下边是关于如何选择JCO的简介：

Windows XP, Windows Vista, Windows 2003 and Windows 2008

下面介绍如何安装JCO

知道如何选择JCO之后， 安装的过程并不难，只要设好相应的环境变量就好了。下面以Windows 32bit环境为例，同时也会穿插一些Linux的内容。

1. 复制sapjco3.dll到c:/windows/system32/目录，或者， 复制sapjco3.dll到目录D:/Resources/Libraries/SAPJCo/JCO_304，

然后加入目录D:/Resources/Libraries/SAPJCo/JCO_304到环境变另PATH中（至于如何修改环境变量PATH,这里不再叙述）。

注：

在Linux和Solaris环境下，复制sapjco3.so到任何一个目录中去，例如：/usr/local/jco3, 然后修改/etc/profile文件，把目录/usr/local/jco3加入到环境变量LD_LIBRARY_PATH中。

2. 加入windows需要的DLL, 复制 msvcr80.dll 和 msvcp80.dll 文件到目录 C:/windows/system32/

3. 恭喜你，你已经安装好了JCO, 就这么简单， 我们现在要做的就是测试安装成功与否，很简单，打开一个命令行，使用下列命令：

java -jar JCO_DIRECTORY/sapjco3.jar

或者

java -cp JCO_DIRECTORY/sapjco3.jar com.sap.conn.jco.rt.About

如果命令执行无误， 你将会看到一个对话框，如下图所示：

注意变量Paths， JCo Classes 和 JCo library 都被正确的载入了，说明你的安装时正确的。

如果你发现有下面的错误出现，请参考第一部分-如何选择JCO，很有可能你的JVM是32位的，而你选择了64位的JCO,反之亦然。
