java.lang.UnsatisfiedLinkError: java.library.path中没有sapjco3

Question

我在Talend lib目录中有jar和dll。设置了路径和类路径。我还下载并安装了SAP2005Redistribuationsp1修补程序和VC++提供的缺少的dll。我曾尝试在windows2003计算机和XP计算机上运行此ETL作业，结果相同。有人能帮帮我吗。

首先确保你在\lib\java\中有.jar文件，如果你在windows上，你应该把dll和sapjco3.jar放到path中如果你在linux上，你需要把.so文件放到你的路径中。

• 将sapjco3.jar复制到talend lib/java文件夹中，并确保sapjco3.dll位于%PATH% (快速而肮脏地将其放置在windows\system32\中)
• 双击sapjco3.jar进行测试，它应显示有关jar的位置和dll

的位置的信息

Talend OS和sapjco3的常见问题:如果您运行的是32位JAVA，则需要32位版本。64位版本，如果你有64位的java。
