To changue to /ROOT/, Database doesn't exist

Hello, j2ee project work and postgresql. Previously worked on the project in the folder webapps \ Projname and now deployed in webapps \ ROOT for me to disappear from the end of the url / Projname /. I have worked, but now I get an error when trying to connect to the database when the other url before I gave any error. He says that the database "name" does not exist. Any ideas?
