Upon changing from logic:forward to
<body>
<logic:redirect forward="welcome"/>
</body>
I'm getting the same error message.
javax.servlet.jsp.JspException: Error - tag useAttribute : attribute 'title' not found
in context. Check tag syntax
Please excuse my seeming a little thick about this. If I want the first form in my
application to be generated from a tiles definition file, I must do all of the
following?
a.. Since a struts action is not a valid URL target, I need a welcome.jsp type file
that contains either a <logic:forward> or a <logic:redirect>
b.. Since a tiles definition file entry is not a valid target for a struts global
forward, I need to subclass the Action class and forward from there.
c.. This means that my welcome.jsp file will forward to a global forward, which will
forward to an action which will forward to the actual tile definition file form.
Do I understand what is needed correctly?
Is there any plan to simplify this in Struts 1.2?
Thank you,
Ed
