deploy jar file with external libraries

Question

I am finishing a project that I have to deploy as a jar file, in eclipse it works fine, my project depends on two libraries which also both depends on dll files. I have added the path to these dlls to the native library location of each one of the external jars. Then I export project as a jar file using the eclipse runnable jar file export wizard I get the jar file in the specified location, it runs but when I click on a button that calls one of the libraries I get I get java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path on the console.

Edit : When I copy the dlls in [...]/jre7/bin/ folder my application works, but I want that my application runs without having to do this manipulation.

Regards.

Run your jar file with console. Using following command: `java -jar app.jar` — Vighanesh Gursale, Oct 24 '14 at 20:55
Yes I did and I get java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path, I added the path to the dlls (which are on my desktop). What am I doing wrong? — user3382344, Oct 24 '14 at 21:02
So the problem is your path for the file. You must read this post http://stackoverflow.com/questions/944610/how-do-i-access-a-config-file-inside-the-jar — Vighanesh Gursale, Oct 24 '14 at 21:13

Run like this: java -Djava.library.path=/path_to_dll -jar app.jar

Thank you for the answer, it did work but the problem is that I want the users to start the app normally without having to use a terminal. That means that the path should be added to the application before exporting to .jar, which I am unable to do. I found another solution to put the dlls inside [...]/jre7/bin/ but that also needs manipulations from the end users. – user3382344 Oct 25 '14 at 19:13
