Ah. I didn't know you were using <jsp:useBean>. In <jsp:useBean> you have to state the fully qualified classname (that is including the package). If you do so and do not use NewBean1 anywhere else besides in <jsp:set/getProperty>-tags importing the class won't help.
Anyways, if you do not succeed, please attach your JSP.
