Simple working GWT demo?

[Fireball]

Does anyone have a working gwt demo? I tried this simple script but got errors either with "mvn gwt:run" and with "mvn jetty:run":

// Spring Roo 1.1.0.M1 [rev 3a0b8a3] log opened at 2010-05-19 22:27:00
project --topLevelPackage com.hra.roogwt
persistence setup --provider HIBERNATE --database HYPERSONIC_IN_MEMORY
hint
entity --class ~.domain.Person --testAutomatically 
field string --fieldName name --notNull 
field number --fieldName age --type java.lang.Integer --notNull 
hint
hint gwt
gwt setup
hint
quit
// Spring Roo 1.1.0.M1 [rev 3a0b8a3] log closed at 2010-05-19 22:30:17

Any hints what I am doing wrong?

Thank you,

I'm new to roo, but you might check out http://static.springsource.org/sprin...ro-first-steps

You might need to do a:
roo> perform package

BTW, I tried mvn jetty:run, but got this error

2010-05-19 16:56:32.001:WARN::/hello/timers/1
org.apache.tiles.impl.CannotRenderException: JSPException including path '/WEB-INF/views/timers/show.jspx'.
        at org.apache.tiles.impl.BasicTilesContainer.render(BasicTilesContainer.java:692)

mvn tomcat:run worked for me.

It's not working. Here is a really simple script:

// Spring Roo 1.1.0.M1 [rev 3a0b8a3] log opened at 2010-05-20 20:45:03
project --topLevelPackage com.test.roogwt
persistence setup --provider HIBERNATE --database HYPERSONIC_PERSISTENT 
entity --class ~.domain.Person --testAutomatically 
field string --fieldName name --notNull 
field number --fieldName age --type java.lang.Integer --notNull 
gwt setup
perform package
quit
// Spring Roo 1.1.0.M1 [rev 3a0b8a3] log closed at 2010-05-20 20:49:48

Neither "mvn tomcat:run" nor "mvn jetty:run" is working. I always get the following error:

type Exception report

Am I missing something?

P.S.: OS is Windows 7

Last time I checked with the roo-dev branch I had to do a mvn gwt:run

it would take me to http://127.0.0.1:8888/ApplicationSca...7.0.0.1:999 7

The irony of running the app was that I was on Ubuntu 64 bit linux with Google chrome and I could not run the app in dev mode as 64 bit linux version of chrome is not supported by Google (yet)

Hi! You can check small howto in my blog: http://www.emforge.net/web/akakunin/...hen-30-minutes

Cannot say everything working - but at least it may be used as some start-point

I am getting the following error when I do 'mvn package':

[ERROR] The import org.springframework.roo.addon.gwt cannot be resolved

Is anybody else is getting the error or know how to fix it? I am using spring-roo-1.1.0.M1 .

[adeveloper]

I found the reason why I was getting the error. The org.springframework.roo.annotations-1.1.0.M1.jar file does not contain RooGwtMirroredFrom.class . I manually added this class (can be found in the roo download) to local maven directory's org.springframework.roo.annotations-1.1.0.M1.jar, then the problem went away. I wonder how come other people did not get this error.

Well with gwt:run I got the following error:

Almost the same problem:

When clicking on "Create pet" I get a bunch of errors in PetEditView_BinderImpl.java
