Subject RE: Sessions mix-up on Tomcat 6.0.26 on Linux
Date Sat, 21 Aug 2010 04:35:58 GMT
Hi, i have been trying to post emails on this list but getting 
mailerdeamon replies that only subscribers can post. i dont know what happened 
there....so i subscribed my other email address....
 
ok now for the topic at hand,
 
Wesly, udac is a public class which exists in the same package and login is a 
static function. I think that much is pretty obvious. I had proper naming 
conventions but when i moved my source code to linux, my entire files names were 
changed to lower case, and the application could not find the classes and jsp 
files. i didnt know any other way(and didnt have any time for RnD) so i changed 
the names of classes and jsp files to lower. any ways, my original topic is 
sessions mix up, do you see any relevance of sessions in udac class? sessions 
are getting created in loginmanager.

Maybe its just be but I still don't see where uadc is declared or even
imported.
