Hello again.
Finally I can confirm I was lost, absolutely lost… but now I'm found… :lol:
The problem was quiet more easy than any theory I had in mind… in my computer I had installed a tomcat server that got port 8080 for itself, while the tomcat server that's provided within Netbeans was using port 8084. The deployment that was triggered in netbeans runned on its own server, trying to connect from port 8084… notice that the repository location is listening on its port 8080… question: is it necessary to establish the connection from the very same port in both computers connecting?
I've deployed the .war manually on the previously installed tomcat server, on port 8080, and it has connected with Alfresco repository fine. So the problem's resolved.
Hope this will help someone anytime.
Thanks to everybody.
