Good afternoon, you guys,
Me and a friend are servicing a system and we’re trying to generate a system jar. So far so good, the system compiles normal and all, but when we open the generated jar file it just doesn’t open. I went to try to open the jar at the windows command prompt and for there I could notice the existence of an exception.

If anyone can help I really appreciate.

In fact, the file .jar is opened and the program starts, but, as the exception shows, there is no class called com.jtattoo.plaf.fast.FastLookAndFeel in that file, and how it’s probably being used in UIManager to define the look and Feel, is one of the first things that happens in the application and therefore it ends up not seeming to be opening.
If you use the Jtattoo as a library in Build Path, if using the Eclipse there is an option to insert libraries in the files .jar, when you export as "Runnable JAR". If you prefer, use Maven and you won’t have to worry about that if you use the Goal "package". There is also the option to include the class manually in the file .jar, but you would have to do this whenever it generated a new file .jar, which is not at all productive.
