I must pass the result of request.getRemoteUser()
because it is a "Java class" that "receives" the
hidden field. If you read my code carefully, you will
see that FindEditorData.java is a Java class and I
cannot use 'request' or 'session' in a Java class. It
takes a servlet or a class extends Action to use
'request' or 'session'.
But, this class is of ProcessAction type defined in
the struts-config.xml:
<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>
And, it is easy to see that I use container-managed
authentication. In my JSP, there is <req:isUserInRole
role="editor"> before reaching <% String
username=request.getRemoteUser(); %> Again, I have
provided my code:
<req:isUserInRole role="editor">
<html:form action="/find/Category">
<% String username = request.getRemoteUser(); %>
<html:hidden property="keyName"
value="journal_category"/>
<html:hidden property="username"
value="<%=username%>"/>
<html:submit>View Articles</html:submit>
</html:form>
</req:isUserInRole>
