Error in preparing standalone Java application with external libraries

Question

I have made a Java serial Interface using RxTx libraries in Netbeans 7.2.1 which works fine.

Tested it with NULL modem and it works fine. Now I need to create an exe which I can distribute.

So,Now I am trying to make a jar file for my project. What I did-

and then clean and build to get jar at location

"D:\\Glaswegian\\Java\\Slides\\RxTx\\SerialCommInterface\\SerialCommInterface\\dist"

with below structure

with lib having RxTx.jar

Now when I try to run from command prompt: I get below error

Can anyone please let me know how to resolve this?

Have refered Run jar file in command prompt How can I include external jar on my Netbeans project

But not able to resolve it.

Answer 1

The system cannot find some native libraries (which probably are needed by RxTx).

Assuming that the native libraries ( *.dll ) are in the lib folder - try to run the app like this:

java -Djava.library.path=lib -jar SerialCommunicator.jar
