“No suitable driver found” when running from JAR [duplicate]

Answer 1

You could go for the fat-jar approach. You can see it here if you use ant.

If have a maven project you could have this plugin to create a fat-jar

The benefit of a fat-jar application is that you could have everything inside one jar and don't need to worry with the lib dir like it was mentioned in another answer.

Also be careful with hard-coded paths like:

String strurl="jdbc:ucanaccess://C:\\Users\\Paul\\Desktop\\Spelli\\RispostiDB.mdb";

that you have in your code.

Answer 2

When you build your project in NetBeans it creates a dist folder in the home folder of your project, puts the JAR file for your code in that folder, and also puts the dependencies (JAR files for required components like UCanAccess, Jackcess, HSQLDB, and Apache Commons bits) into a subfolder named lib. You need to ensure that the lib folder gets copied to the target machine and placed in the same folder as your main JAR file. Look here for details.
