SQLite and JDBC: Returns UnsatisfiedLinkError

I am running Xubuntu in VirtualBox. I installed sqlite3, which for some reason does not come bundled. I added sqlite-jdbc-3.8.7.jar to my build path and run this simple code to test it.

import java.sql.*;
public class JDBC_test {

    public static void main(String[] args) throws ClassNotFoundException, SQLException {
        Class.forName("org.sqlite.JDBC");  
        Connection connection = DriverManager.getConnection("jdbc:sqlite:test.db");
        connection.close();
    }
}

      

        
        
        
      

    

I am getting this error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: org.sqlite.core.NativeDB._open(Ljava/lang/String;I)V

I am getting the same error when I try to connect to an existing DB, replacing "test.db" with the full path to the file. Any ideas why?
