Generating .jar using Java 1.7 with Eclipse and SQL Server 2012 database with Windows authentication

Question

I am using Java 1.7 Desktop application with Eclipse and SQL Server 2012 database with Windows authentication. When I run through eclipse works correctly. The problem is when I try to generate a .Jar. The application works correctly but when I am going to do some query on the database the application stop working. I wonder what are the correct settings I have to do on the machine (the same machine) and time to generate. Jar, thanks.

Got this error by compiling in the prompt:

C:\Users\jean>java -jar C:\Users\jean\Desktop\Jean\aee.jar

My problem is solved by just adding the .dll in the same directory of the .jar.

I'm guessing you use some libraries for your project. If you export a jar from Eclipse, it doesn't package those libraries into that jar automatically. As an easy way out you coul'd use the Fat Jar Plugin . It worked fine for me in the past.

Ultimately you want to use a build and dependency management tool like Maven .
