我的 jar 和 dll 位于 Talend lib 目录中。路径和类路径已设置。我还下载并安装了 VC++ 2005 redistribution sp 1 补丁以及 SAP 提供的缺少的 dll。我尝试在 Windows 2003 机器和 XP 机器上运行此 ETL 作业，得到相同的结果。有人可以帮我从这里出去吗。

首先确保 \lib\java\ 中有 .jar 文件
如果您使用的是 Windows，则应该将 dll 和 sapjco3.jar 放置到 PATH
如果您使用的是 Linux，则需要将 .so 文件放入您的路径中。
- 将 sapjco3.jar 复制到 talend lib/java 文件夹中，并确保 sapjco3.dll 位于 %PATH% 中（快速将其放在 windows\system32\ 中）
- 双击 sapjco3.jar 进行测试
它应该显示有关罐子位置的信息
以及dll的位置
Talend OS 和 sapjco3 的常见问题：
如果您运行 32 位 JAVA，则需要 32 位版本。
如果您有 64 位 java，则为 64 位版本。
