Hey Community, I have written a Login where the User Name and Password where saved in SQL Datebase , that works fine. To start connection i loaded a .jar called mysql-connector-java-5.1.21-bin.jar ,but the problem is if i export the Project to a jar File I cant intelize the connection because this library (i think) is not loaded in the jar file because it is only a /userlib in Greenfoot .

One possibility is to extract the contents of the library into your scenario folder, before you export the scenario. You will need to load the Mysql connector class manually using: 
 Class.forName("com.mysql.jdbc.Driver") ;

where should i add this line
You just need to execute that line before you try to open a database connection.

Extract, not copy. Directly into the scenario folder. A jar file is really a zip file, so you can extract the contents with winzip for example.
