Is it important how a war is called? Does it have any effect on whether it will work correctly? Let's say you're building a war with maven, naming it in one way and then manually rename it to some other name before deploying it somewhere on a server and running it, would it have any effect on working? Like deploy issues, etc?
Let's say with the maven war plugin you set it to generate something.war and later rename it to newfilename.war before deploying. What is your experience/knowledge there?
The name might matter depending on the servlet container: tomcat uses the name of the war file without the .war extension as the context path. This can be adjusted though using container-specific configuration files inside the .war file.
Obviously it would also matter in that case when you're trying to access it.
