What i am doing wrong? Help please.

回答1:

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.) 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.

回答2:

You have to put your DLL to place where JVM can find it. Typically it should be located under your application folder but you should specify option -Djava.library.path=PATH TO YOUR DLL when you are running java.

回答3:

Safest way is to put your DLL file into system32 folder.
