Simple Google Web Toolkit Project with Spring Roo

After watching Google I/O 2010 Keynote (Day 1, pt. 9) from Youbube, I cannot wait to have a try on Spring-Roo 1.1.0M1 with GWT 2.1 Milestone 1. In this post, I will follow Ben's demonstration on Google I/O to create the same project using SpringSource tool suite with Google integration.

1. Setup development enviornment

Download SpringSource Tool Suite (STS). We need version 2.3.3.M1 which has Google integration.
Then use its extensions dashboard to install the Google Plugin for Eclipse:

2. Create Roo project

In STS, click "File->New->Roo Project",
Then "Next", "Finish".
You will see our "demo" project appears in Package Explorer after output some building information from Console. Now switch to "Roo Shell" tab, we are ready to type in some commands.

3. Develop our project using Roo.

It's time to start our Roo journey, type command in "Roo Shell":

setup persistence:

persistence setup --provider HIBERNATE --database HYPERSONIC_IN_MEMORY

create Employee entity class with two properties:

entity --class ~.server.domain.Employee
field string --fieldName firstName
field string --fieldName lastName

add gwt support:

gwt setup

However, I occurs an error after this command,
"The project 'demo' does not have any GWT SDKs on its build path"

So I add GWT Library to this project manually:
right click on "demo" project, "Build Path"->"Add Libraries", choose "Google Web Toolkit".

let's roo do pack:

perform package

That's all, let's quit Roo:

quit

now open any command line tool you prefer, "cd" into the "demo" project directory,

mvn gwt:run

in the "GWT Development Mode" windows, click "Launch Default Browser":
