Goal: Use Spring Roo - GWT - GAE to create a Pokemon website for my son

[dclaverty]

mvn gae:deploy

Definate user error. In a previous attempt not recorded here I tried to deploy to GAE and failed. Now, when I try to do the deploy from maven as part of this thread I get the error described below. I am now trying to figure out how to either rollback (very little detail on how to do this) or set it to another version that is not stuck in purgatory. I will keep you updated. If anyone has an example on how to roll version 1 back please share.

Seems to have fixed the version issue

I still need to find out how to set the appversion

[dclaverty]

mvn gae:deploy

Now that I resolved the rollback issue the deploy command seems to run to completion successfully.

Launched my application on Google App engine

http://1.maxcardtrader.appspot.com

it redirects to

http://1.maxcardtrader.appspot.com/_...nScaffold.html

And the page shows

404 Not found

Error: NOT_FOUND

Roo by default seems to have implemented some form of login I am not familar with, or know how to handle.

Any way to turn this feature off, or is this a red herring for something else going on ?

RESOLVED

To resolve this issue you need to log onto your appengine console and go to application settings

Go to Authentication Type. Mine was defaulted to (Experimental) Federated Login. Once I switched to Google Accounts API my site came up.

STUCK

Next I would like to see if I can try to upload an image of the pokemon card

~.Card roo> focus --class ~.server.domain.Card
~.server.domain.Card roo> field file --fieldName image --contentType JPG

Updated SRC_MAIN_JAVA\com\maxcardtrader\server\domain\Card .java
Updated SRC_MAIN_JAVA\com\maxcardtrader\server\domain\Card _Roo_JavaBean.aj
The primitive field type, byte of 'getImage' in type Card is not currently suppo
rt by GWT and will not be added to the scaffolded application.
~.server.domain.Card roo>

Not supported.

[dclaverty]

To attempt to put in the file upload feature, or perhaps hook up to some restful api for images I decided now was the time to try to run Roo from the Spring Tool Suite.

I understand you can import as an existing Maven project

or

run mvn eclipse:clean eclipse:compile
then import it as an eclipse project.

[dclaverty]

Importing as an existing Maven Project

First issue

Before import happens you already know there are issues with the pom setup

Second issue

Project gets reported as a legacy project. I said yes to upgrade the project.

Third issue

Errors are shown after import. Seems that an annotations jar cannot be found.

RESOLVED

I had the Roo 1.3.0 Snapshot in my spring source directory. Spring source picked this up and made it the default roo installation.

I put the default ROO installation back to 1.2.2

I tested clean, compile and gae:deploy from STS and they all seem to work fine when imported as a maven project.

The errors I see now do not seem to have any effect on running the maven commands.
