Thanks for the answer.
I've checked the contents of the HTTP Request and, the first time I attempt
to display the Form the Request is empty (as I would expect). There is no
org.apache.struts.taglib.html.BEAN object that I can see using the
request.getAttributes() method.
I appear to be having different behaviour entering the same JSP page with
the same Request contents (i.e. nothing) depending upon whether or not the
WAR file was unpacked when Tomcat was started.
I've tried explicitly creating an instance of the Form Bean in the JSP page
using jsp:useBean. If I create it in the Request then I get this exception
every time I visit the page regardless of whether the WAR file was unpacked
or not. If I put it in the Session I get the initial behaviour.
I'm sure that there must be Struts pages using FormBeans running under
Tomcat 4.1.12 out there so what am I doing wrong? One route would be to
upgrade to Struts 1.1b2 but I'm a bit reluctant to deploy an application
using Beta version software.
Any suggestions anyone?

I suggest you develop with tomcat 4.1.12 since you're deploying on that
version. It will make your life easier with less surprises. You should
check what object is stored under org.apache.struts.taglib.html.BEAN in the
request. It may not be the bean you think it is.

Subject: Struts 1.0.2, Tomcat 4.1.12 Web-App start-up funny

A plea for help to the great Struts User community.
I'm in the process of deploying our first Struts-enabled Web-App onto a
separate Staging Server. This is running Win 2K SP3, JDK 1.4.1 Tomcat
4.1.12.
Everything works fine when I first deploy my WAR file and start Tomcat. It
is unpacked correctly and the Web-App runs fine. If I stop and re-start
Tomcat I get the following error message when I attempt to access an Admin
Page using an HTML form with an associated Struts Form Bean :-
javax.servlet.jsp.JspException: No getter method available for property
archiveServer for bean under name org.apache.struts.taglib.html.BEAN
at
org.apache.struts.taglib.html.SelectTag.doStartTag(SelectTag.java:304)
at
org.apache.jsp.ResultArchiveAdmin_jsp._jspService(ResultArchiveAdmin_jsp.ja
v
a:265)
The relevant part of my Struts-config.xml is :-
form-beans
form-bean name=ResultArchiveAdminFormBean
type=com.anritsu.eu.Expresso.Beans.ResultArchiveAdminFormBean/
/form-beans
...
!-- Add Result Archive --
actionpath=/AddArchive
type=com.anritsu.eu.Expresso.ActAddResultArchive
name=ResultArchiveAdminFormBean
scope=request
validate=true
input=/ResultArchiveAdmin.jsp
forward name=success path=/ResultArchiveAdmin.jsp/
/action
I think that this exception is telling me that the Struts TagLib could not
find a matching getArchiveServer() method in the Form Bean. But why did
it
work the first time I ran up Tomcat? I have checked that the Bean does have
a matching method. Is it significant that the exception does not mention
the
ResultArchiveAdminFormBean by name?
This is a bit frustrating as the same WAR file runs fine on my development
machine, but this is using JBuilder 6 Tomcat 4.0.1. I would prefer to use
a later version of Tomcat for deployment.
Obviously I must have missed something out from either the
Struts-config.xml, web.xml or in the JSP for this page. As this happens the
first time I attempt to access this page could it be a problem with an
instance of the FormBean being created? I've not explicitly added a
jsp:useBean ... statement into the JSP page as I thought that Struts
would
sort this all out for me. Do I need one?
Any ideas would be gratefully received.
Many thanks.
Neil.
