Answer 1

Artifact first_java_web:war exploded: Error during artifact deployment. See server log for details.
Where are the details?
From what I have, I can say the following.
1. In jsp (do you have jsp ?) you messed up some of the tags (for example, didn’t close it)
2. You screwed up anything in the war itself. Again, See server log for details.
