I am getting the following error and I am stuck..

ERROR
message /index.jsp (line: 28, column: 4) Unable to find setter method for attribute: name

description The server encountered an internal error (/index.jsp (line: 28, column: 4) Unable to find setter method for attribute: name) that prevented it from fulfilling this request.



My understanding
Line 28 is <html:form action="Lookup" name="lookupForm" type="ch03.LookupForm" >


name on the index page represents the javabean data
type = the qualified path and name of the javabean

index.jsp

<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

We were able to fix it. I delete the strike lines and it worked.
