There is nothing specific to JSPs here. The compiler simply cannot
translate your JSP. Given your information the class it does not know of
is "NewBean1".
You probably have to import the class into your JSP. Since the localized
message you have posted suggests you are German, you might be interested
in this link:
http://jsptutorial.org/content/syntax#innerLink4
You will find some examples scrolling down a bit about how to import
classes into your JSP.
If this doesn't help, please attach your JSP, the bean and the complete log.
