Re: Very Troubled in Finding Ways to Pass a Variable to a Class
How does your FindEditorData class get called? It is the responsibility of
the caller to tell this class who the user is. I assume that there is an
Action mixed in here since the call is made in response to an HTML form
being submitted. Have your Action figure out who the user is
(request.getRemoteUser()) and then pass that information along to your
FindEditorData class.
Don't trust a hidden field to tell you who the user is. You will get hacked.

Subject: RE: Very Troubled in Finding Ways to Pass a Variable to a Class
It is wonderful to know that there are some ActionForm
methods that holds true in the
scaffold.ProcessAction's execute() method. It gives
the hope that my problem could be resolved.
Via a submit button in my JSP, I try to pass two
variables; username and keyName, to my Java class
(FindEditorData.java) with the
type=org.apache.struts.scaffold.ProcessAction, and
this Java class has this method:
public Object execute() throws Exception { ... }
1. if I use the hidden field technique (see below)
inside the JSP html:form tag:
% String username = request.getRemoteUser();%
html:hidden property=username
value=%=username%/
html:hidden property=keyName
value=journal_category/
How do I retrieve the value of username and keyName in
the Java class? Probably due to my lack of knowledge
of the ActionForm, I got compilation error cannot
resolve symbol: request or cannot resolve symbol:
session because FindEditorData.java does not extend
HttpServlet and FindEditorData.java does not extend
Action.
2. if I want to get 'username' in the Java class
instead of passing the 'username' as a hidden field
from a submit button in my JSP, how do I do it?
String username = request.getRemoteUser(); gives me a
compilation error cannot resolve symbol: request.
The action mapping in my struts-config.xml looks like:
action
roles=editor
path=/find/Category
type=org.apache.struts.scaffold.ProcessAction
parameter=org.apache.artimus.article.FindEditorData
name=articleForm
scope=request
validate=false
forward
name=success
path=.article.Result/
/action

So what is the problem with your class? Why can't
you utilize it from
one of these places that you do have access to these
things? What
