I used the following code. It works perfect in the IDE. But running from the jar file after clean and build in IDE, it http://stackoverflow.com/questions/19972708/unsatisfiedlinkerror-accessing-dll-files-from-jar-file shows following error.

So check the current directory. But if you know the path of the library to load you should use System.load(…) specifying the actual path instead of hacking the search path for System.loadLibrary(…) –Holger Nov 14 '13 at 10:19 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote For accessing dll files through java code(), On
dll in java.library.path - Cause and Solution "Exception in thread "main" java.lang.UnsatisfiedLinkError: no dll in java.library.path" is one of thefrustratingerror you will get if your application is using http://javarevisited.blogspot.com/2012/03/javalangunsatisfiedlinkerror-no-dll-in.html native libraries e.g. .DLL in Windows or .SO files in Linux. http://osdir.com/ml/java.netbeans.devel/2003-10/msg00224.html Java loads native libraries at runtime from either PATH environment variable or location specified by java.library.path system property depending upon whether your Java program is using System.load() or java.lang.System.loadLibarray() method to load native libraries. If Java doesn't find them due to any reason it throws "java.lang.UnsatisfiedLinkError: error loading no dll in java.library.path". Some of the most common UnsatisfiedLinkError is"java.lang.UnsatisfiedLinkError: no ocijdbc10.dll in java.library.path" and"java.lang.UnsatisfiedLinkError: no ocijdbc11.dll in java.library.path", which comes when you try to connect to Oracle 10g or 11g database from Java program using OCI JDBC driver. If you write games in Java program using lwjgl then you might have seen this error as well error loading win32com "java.lang.unsatisfiedlinkerror no lwjgl in java.library.path", which comes when Java doesn't find a native component of the lwjgl.jar library. It also common on Java application which uses JNI to link some core legacy libraries in C and C++. I first encounterd this error while writing some Tibco Rendezvous Messaging code which uses some windows specific dll, which is installed as part of TIBCO RV installation. I was getting"java.lang.UnsatisfiedLinkError: Native library not found" which was caused by "java.lang.UnsatisfiedLinkError: no tibrvnative in java.library.path". I wasted a lot of hours playing with PATH, java.library.path and others only to learn from experience. Here you will learn the root cause of "Exception in thread "main" java.lang.UnsatisfiedLinkError: no dll in java.library.path" and learn how to fix this Exception in Java. Cause of java.lang.UnsatisfiedLinkError: no dll in java.library.path: When you loadnative librarieslike .so on Linux or .dll on Windows using System.loadLibrary() Java looks for those shared libraries in both PATH environment variable and java.library.path system property, If it doesn't find shared library it throws "Exception in thread "main" java.l
programs that I have tried to compile and execute is the SimpleRead program provided with the default download of javax.comm. I am getting the following error message when I execute the program (from the Build menu): "Error loading win32com: java.lang.UnsatisfiedLinkError: no win32com in java.library.path" However, if I try running the same program via the NetBeans debugger, everything works fine. I have mounted the "comm.jar" file (if I don't do this, I get an error when I run via the debugger). I have also tried adding "-cp:a
