Where is the class Transaktion? Either it can't find the class or the class doesn't contain the method setBelopp(I)V.

Do you have mis-matched versions of that class? You compiled with the version that has that method and then tried to execute with another version that did not.

Check this first of all in your code, exist or not?

Hello,

I am sorry, It takes time with my answers. I am not at home right now, I am traveling..:)

no, I did not find out some solution yet, but I will recur later, (if it is OK), because I have to check this class with name Transaktion. It is exist any way..hmm

thank you for your attention, I am very appreciate that.

Regards,
MK :)

Where is the class Transaktion? Either it can't find the class or the class doesn't contain the method setBelopp(I)V.

That is not true: if the JVM couldn't find the class itself it would have said so; it just can't find the method void setBelopp(int) in that class. It's probably a class version mixup; a recompilation of all the classes will solve the problem or shows a bug: a missing method.

kind regards,
