Hello Vladimir,
Thank you for your help.
And I'm still have some questions.
Why do we need to implement "some interface"? java.io.Serializable I
think? But anyway I implemented this interface - it doesn't work. This
approach works for EJB. :)
And my question is: Is there any way to use "some shared" object with
reloadable servlets without Tomcat restart?
Thanks.
