This is due to how Java deals with classes in the "unnamed" package when
compiling classes that are in a named package. JRun apparently generates
a servlet with a package declaration, and your bean is in the "unnamed"
package. There are two solutions:
1) Add <%@ page import="formbean" %> to you page,
2) Add a package declaration to your bean, e.g. "package com.mycomp;"
and place the class file in the corresponding subdirectory in the
classpath (classes/com/mycomp in this example), and modify the
<jsp:useBean> class attribute accordingly (class="com.mycomp.formbean).
I recommend 2) even though it's more work, since packages help you keep
your code structured and avoid name clashes. A minor detail, but you may
also want to follow the standard Java naming conventions, which say that
class names should start with an uppercase letter, e.g. FormBean, see
<http://java.sun.com/docs/codeconv/html/CodeConvTOC.doc.html> for details.
