When my struts.xml package tag don't have a namespace attribute, the getTutorial.action works in all "namespace" same that doesn't exists.

ex:

After I added the namespace attribute in my struts.xml package tag the getTutorial.action work only in defined namespace.

Why ??

I'm using
- eclipse 3.7
- Tomcat 9
- struts 2.5

Obs: sorry my english.

Hey,
The web page should be opened automatically right.
You did changes in the URL and the page opened. But that should not be the case while running the application right.
I am getting the index page while running the program. How do I solve that problem?
