Why I saw this error HTTP 500 component definition not found

I downloaded a SecureLogin project because I want to insert it in my project. I made my project with a theme that I have downloaded from github. Both of project are build with maven.

If I launch both project, both works correctely. Now, I paste all my theme webapp project in webapp folder in SecureLogin project. I want that after the login, my controlpanel will be appear.

But after I try to run controlpanel.zul I saw this:

HTTP Status 500 - file:/C:/xampp...gin/applications/index.zul:44:45: Component definition not found: navbar in [LanguageDefinition: xul/html]

and many many exceptions!

Probably there is a problem with pom.xml because seems that he doesn't found some library. But, if I copy some part of MyTheme's pom in SecureLogin's pom I will see HTTP ERROR 404 when I try to launch index.zul of SecureLogin.

How can I merge the two project? Thanks for answer
