For example, the bean:message tag seems to rely on a locale being in the session to work. I can probably live without the bean:message tag, but then I discovered the html:errors tag also seems to rely on a locale being in the session. Both of these problems trace back to the org.apache.struts.utils.RequestUtils class, which appears to use the session. Part of the stack trace is below.
Do you think I would need to subclass RequestUtils and override the method that uses the session, or is there some easier way to just get tags like bean:message and html:errors to work without sessions enabled?
Thanks,
Brad
