Subject Re: Loosing identify when switching to non-protected webresource
Date Tue, 07 May 2002 12:06:03 GMT

I am experiencing the exact same problem. Here is my post to the struts list:

I have found the same using jb241a+tc323 as well as jb300RC2+tc403.

I started looking at the tomcat code but I'm not sure I want to commit the time it may take
to understand the intricacies when someone 
else may well have an answer.

I'd like to know whether this is worth pursuing or if perhaps it is better to sacrifice the
declarative model for a role-your-own approach.
