问题描述
当我使用双击时，我的Java应用会完美启动。
我的路径：
When i'm using double click my java app starts perfectly. My path:
PATH=...C:\Program Files\Java\jdk1.7.0_02\bin;...
但是当我从cmd运行应用程序时：
But when i'm running app from cmd:
C:\Program Files\Java\jdk1.7.0_02\bin>java.exe -jar C:\Users\zagorulkinde\Docume
nts\ps_client_lib\bin\Win32\GUItest.jar

如果我要指定dll：

rs\zagorulkinde\Documents\ps_client_lib\bin\Win32\Pc_client_lib.dll" -jar C:\Use

我在做什么错？
推荐答案
1。）-Djava.library.path指定本地的 path 库是实时的，它没有指定库本身。 （即-取出文件名，将其更改为 -Djava.library.path = C：\Use ）
rs\zagorulkinde\Documents\ps_client_lib\bin\Win32 \
1.) -Djava.library.path specifies the path to where native libraries live, it doesn't specify the libraries themselves. (i.e. - take the filename out, change it to -Djava.library.path="C:\Use
rs\zagorulkinde\Documents\ps_client_lib\bin\Win32\")
2。）区分大小写可能是一个问题-您将文件引用为 Pc_client_lib.dll，并且 PC_client_lib在不同的位置。确保在 loadLibrary 中使用的名称与实际的.DLL文件名具有相同的大小写。
2.) Case-sensitivity might be an issue - you're referencing the file as "Pc_client_lib.dll" and "PC_client_lib" in different places. Make sure the name you use in loadLibrary has the same case as the actual .DLL file name.
