Appengine error running GWT expense sample

[smloh]

I'm just starting to try out Roo & STS and this issue gave me grief too.
Finally got mvn gwt:run to work after adding the dependency as suggested by chh315, but still having some difficulties getting the sample project to run properly within STS.

All this was with a clean install of STS and meticulously following the instructions here: http://blog.springsource.com/2010/06...h-roo-and-gwt/
It's definitely made my adoption of roo take much longer than I thought it would.

When I do roo perform tests I get:

I swear. Nothing I've tried with maven has worked. I've tried numerous examples and they all fail at some point. I've tried deleting the .m2 folders as specified but it didn't work.

Turns out: dependency add --groupId com.google.appengine --artifactId appengine-api-1.0-sdk --version 1.4.0

worked for me too. First time I tried it I copied it from the browser.. didn't work.

Questions is, why isn't this part of the original perform tests script?

try this in spring roo
dependency add --groupId com.google.appengine --artifactId appengine-api-1.0-sdk --version 1.4.0

Hi! What do you mean by this exactly?

Typing this in the Roo shell?

I am fairly new to Roo and I tried in the Roo shell and it says that it cannot find the dependency command?

It doesn't seem to be a maven command either.

Do you need to do this while in STS?

I know this seems a newbie question, but feedback like this can also help other new users who might want to migrate to using STS.

From within the roo shell. dependency is indeed a roo command as you will see if you type, help dependency

Maybe you misspelled something.

You were right!

I also found out that my "expenses" directory was empty when I typed in the command. So what I did now was to run sa expenses.roo first, then the "dependency add" command.

However, when I ran mvn gwt:run, it remains stuck downloading doxia-modules-1.1.4. Which is possibly due to the network problems I am currently experiencing with my internet service provider.


*UPDATE: mvn gwt:run works now. I am able to open the application on Chrome.
**UPDATE: mvn tomcat:run Gets me stuck with a "loading" notification.
