Grail run-app | Grails run-app change default port | Grail run app locally

You need to run app in grails before deploying it on your web application. Luckily, grails support them.

Simply you do follows:

1. Go to your grails directory

2. Use "grails run-app" command

3. If you want to change default port of grails run-app 8080. How to? Use command:  grails -Dserver.port=9001 run-app

Run the grails run-app command.
The grails run-app command starts the Enterprise Server in the background and runs the application in one step. You don't need to create a WAR file or deploy your application.
To test your application, point your browser to http://host:port/app-dir-name.
For example, point to http://localhost:8080/helloworld. You should see a screen that begins, “Welcome to Grails.” Selecting the HelloController link should change the display to, “Hello World!”

Grant for each table:

GRANT permission ON database.table TO 'user'@'localhost';

Grant for database:

GRANT permission ON database.* TO user@'localhost' IDENTIFIED BY 'password';

Once you have given the desired privileges for your user, you will need to run this command within the MySQL command prompt:

what are the differences between CSV and XLS?

Today I think about CSV file & XLS file, and what are the differences between them?

Humhum, as I known that XLS is file format of Microsoft Excel. CSV is format frequently export by IT man.

Google now, I get one result:

Comma-Separated Values (CSV):These files hold plain text as a series of values (cells) separated by commas (,) in a series of lines (rows). You can actually open a CSV file in a text editor. Many applications are capable of reading CSV files, and many languages provide built-in functions that simplify reading/writing CSV format.

Excel (represented as XL) Spreadsheet (XLS):It is an MS Excel workbook binary file, which holds information about all the worksheets in a workbook, comprising both content and formatting (number masking, colouring, conditional formatting, etc), and can also hold additionals like charts, images, etc. XLS files can only be read by applications that have been especially written to read their format, and can only be written in the same way.
