如何配置RTXCommon.jar

Question

我有一个java程序，我想使用RTXCommon.jar，所以如果我尝试使用它，我会遇到以下错误

然后右键单击项目，java构建路径，然后找到RTXCommon.jar，选择本地库路径，编辑，然后选择文件夹C：\SWInstall

在此文件夹中，我有copy rtxSerial.dll rtxParallel.dll。然后我已经运行了这个项目并工作了。但是，如果我尝试生成jar文件，然后运行它，我会得到相同的错误。

我怎么才能修复它呢？

要检查的最重要的事情之一是你没有提到的是验证你使用的是32位还是64位的RTXCommon.jar，如果你使用的是RTXCommon.jar 82位，你应该使用java32位。

然后，您必须检查RTXCommon.jar是否指向本地库的正确位置，为此，在eclipse下，右键单击您的项目并选择属性，然后选择java build path，在对话框中单击RTXCommon.jar前面的小箭头。双击本地库位置并输入DLL的路径。

如果你愿意在不同的机器上运行你的应用程序，记得把你的DLL存储在一个通用的文件夹中(以windows为例，在程序文件下)，这样你就可以防止这样的bug发生在其他用户身上。其他操作系统也是如此。
