I don’t think I deserved the downvotes but hey.
Well anyway the problem was that I was referencing .jars within .jars, I didn’t think that this would be a problem but it was. The solution was to put the .jars (libraries) alongside my compiled application .jar and update the manifest accordingly. it is also possible to use .jars within .jars but you will need the use of another set of classes to let you do this. Eclipse has this and if you build excecutable .jar from within eclipse you can have .jars within .jars.
solved .jar does not run and cannot find external jar
