点击resin用来init database的link

http://127.0.0.1:8080/java_tut/servlet/example.servlet.database.InitDatabaseServlet

报错如下，谁知道那里的错？
schema_file: /WEB-INF/sql/default.sql jdbc_ref: java:comp/env/jdbc/test Can't connect to the database at java:comp/env/jdbc/test. Check the configuration to make sure the database is configured properly. java.sql.SQLException: java.net.ConnectException: Connection refused: connect
