Hi, I think that we are in different time zones.
As you have mentioned, I, too, suspected that the
statement in my JSP:
request.getRemoteUser();
returns nothing. Therefore, I did a test in my JSP.
In addition to request.getRemoteUser(); I created
another String manually:
<req:isUserInRole role="editor">
<%
String username = request.getRemoteUser();
String userrole = "author";
%>
<% out.println("The user name is: " + username +".");
%>
<% out.println("The role is: " + userrole +"."); %>
</req:isUserInRole>
And the browser shows:
The user name is: Gloria Jen. The role is: author.
Gloria Jen is the name that I provided while logging
on and authenticated by the container. Therefore, the
request.getRemoteUser(); does not return a null. And
I hope that it means I am not passing a null value
when I use the hidden field technique.
Then, I pass two hidden fields (with value in them)
from my JSP to a Java class (FindEditorData.java),
which is of scaffold.ProcessAction type. One of the
field is passed with its value correctly retrieved.
The other field is passed with its value found to be
null.
What could go wrong? I have been thinking about it
for days and so do those who try to help me.
<req:isUserInRole role="editor">
<html:form action="/find/Category">
<%
String username = request.getRemoteUser();
String userrole = "author";
%>
<%out.println("The user name is: " + username +".");%>
<%out.println("The role is: " + userrole +".");%>
<html:hidden property="keyName"
value="journal_category"/>
<html:hidden property="username"
value="<%=username%>"/>
<html:submit>View Articles</html:submit>
</html:form>
</req:isUserInRole>
