The only case where Struts automatically instantiates a bean is for form
beans. In a JSP page, that only happens in the <html:form> tag. If you
want to refer to a bean outside the form tag, you will need to make sure
it is instantiated already.
One thing to note -- "com.struts.UserBean" sounds like the class name of
your bean, rather than the attribute name under which you would store
it. The class name would be specified (for example) in the
"type" attribute of <jsp:useBean>.
