Hi forum!
Some time ago there was an exception in my console when I close Tomcat with a window opened:

I have readed about the serialization interface and I know why Tomcat tries to register this objects and why when Tomcat tries read again throws the exception. But this message has started show 3 months ago, and under this teory this should be happend from the start... I'm not using a cluster enviroment, I know that if I serialize all classes, this error will disappear but I would like know why this happends now.
Thanks for help people!
Regards:

Mark.

well, finally I've founded the solution. to go quickly, for learn more about the serialitzation objects in Tomcat pls refer to here and this is the solution. In the Tomcat directory(root/conf/context.xml) there is a comented code line like this:
!-- Uncomment this to disable session persistence across Tomcat restarts --

<Manager pathname="" />

Uncomment this line we cant desactivate the serialitzation mode. I hope that this can helps someone, Regards Marky
