I pass two hidden fields: username and keyName at the same time. The keyName is passed and with the correct value in it. The username is passed but its value turns out to be a null.
It is impossible for request.getRemoteUser(); in my JSP returning a null. (see code below) Before it reaches request.getRemoteUser(); the user has already been successfully logged in with a valid name. <req:isUserInRole role="editor"> <html:form action="/find/Category"> <TR> <TD class="option"> <% String username = request.getRemoteUser();%> <html:hidden property="keyName" value="journal_category"/> <html:hidden property="username" value="<%=username%>"/> <html:submit>View Articles</html:submit> </TD> </TR> </html:form> </req:isUserInRole> --- "Yee, Richard K,,DMDCWEST" <[EMAIL PROTECTED]> wrote: > Caroline, > Are you having problems with the username or the > keyName hidden variable?
