推荐答案

在这里是一个德国论坛，在那里解释了问题 [

Here is a German Forum where the problem is explained[^] (translated with Google translator)

so the problem seems to be that you might be using inconsistent JAR-files. Please make sure you have the correct ones.

I have noticed that you have more problems with JASPER. I would like to recommend to buy a book on how to accomplish the tasks ahead. A book reveals some secrets you otherwise would need a keyword to find out about. So a good old fashion book is a good investment (ether for you or for your company).
