Time To Create A Web Application

Once your installation is done, it is time to create a simple web application using Roo. For this example, we consider an on-line movie reservation system called mymovy.

• First create a directory named mymovy:

K:\sbox>mkdir mymovy

K:\sbox>cd mymovy

K:\sbox\mymovy

• Start Roo in this directory 

K:\sbox\mymovy>roo
At the Roo command prompt, enter hint which will provide you the starting steps:

roo> hint

Welcome to Roo! We hope you enjoy your stay!

Before you can use many features of Roo, you need to start a new project.

To do this, type 'project' (without the quotes) and then hit TAB.

Enter a --topLevelPackage like 'com.mycompany.projectname' (no quotes).

When you've finished completing your --topLevelPackage, press ENTER.

...

•  Issue project command with topLevelPackage as the package name, in my case: com.madhusudhan.mymovy:

roo> project --topLevelPackage com.madhusudhan.mymovy
Created K:\sbox\mymovy\pom.xml
Created SRC_MAIN_JAVA
Created SRC_MAIN_RESOURCES
Created SRC_TEST_JAVA
Created SRC_TEST_RESOURCES
Created SRC_MAIN_WEBAPP
Created SRC_MAIN_RESOURCES\META-INF\spring
Created SRC_MAIN_RESOURCES\META-INF\spring\applicationContext.xml
Created SRC_MAIN_RESOURCES\META-INF\spring\log4j.properties
com.madhusudhan.mymovy roo>

• Now, setup the persistence. We use In Memory Hypersonic database as our persistence engine. Issue the following command to create the persistence:

com.madhusudhan.mymovy roo> persistence setup --provider  HIBERNATE --database  HYPERSONIC_IN_MEMORY
Created SRC_MAIN_RESOURCES\META-INF\persistence.xml
Created SRC_MAIN_RESOURCES\META-INF\spring\database.properties
Managed SRC_MAIN_RESOURCES\META-INF\spring\applicationContext.xml
Managed ROOT\pom.xml

• Next step is to create your domain model - entities
