Flex Addon ! Working Walkthrough !

[jblouir]

UPDATED: You need to download SpringSource 2.6
and use the Spring Roo 1.1.3 release that comes packaged with the sts, as well as using the flex addon from...

the most recent nightly build from here

http://s3browse.springsource.com/bro...UILD-SNAPSHOT/

and the annotations jar from

http://s3browse.springsource.com/bro...UILD-SNAPSHOT/


Setup the Roo Environment variables

ROO_HOME = installed roo dir
Add %ROO_HOME%\bin to your path variable

Put the flex addon and annotations jars into your %ROO_HOME%\bundle directory

(you may have to rename your flex addon jar and annotations jar, this may or may not be the case but its something I did and it seemed to resolve an error, if you have any errors about it expecting to find the jar you have included but the name is different rename them to the following...)

org.springframework.flex.roo.addon.jar
org.springframework.flex.roo.annotations-1.0.0.BUILD-SNAPSHOT.jar


The procedure to start a new project is...

1. Open SpringSource Tool Suite
2. File -> New Spring Roo Project
3. Give the project a name and package name, project type standard
4. Make sure your using Roo 1.1.3.RELEASE
5. Then click Finish

Once the project is generated double click on the "pom.xml" then click the "pom.xml" tab at the bottom of the Overview, inside the xml insert the following tag inside of the <respositories> area...

<repository>
<id>spring-snapshot</id>
<name>Spring Portfolio Snapshot Repository</name>
<url>http://maven.springframework.org/snapshot</url>
<releases>
<enabled>false</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>

(The next step is probably optional, but I always setup my database first) Then setup your persistence... for example "persistence setup --provider HIBERNATE --database H2_IN_MEMORY"

Finally type "flex setup" and your project will be prepared to work with flex, then you should be able to use the flex remoting all / flex remoting scaffold commands!

Now I hope we can get this for AIR too!

That doesn't work for me. I followed your instructions exactly, trying various snapshots from April 18 to 20. I'm using Roo 1.1.3 on OS X. I get this error with the flex remoting all command:

Any idea why this is happening? Anyone else getting this?

Hi Krimple, i have not come across that error before, I have actually given up any hope of getting Roo to work, even after doing the instructions above there were still a few things there were off even in my own installation that just were too much of an issue to continue to use it, if I could modify this thread I would probably say "might work" if your lucky, im not sure what else to do, I spent ages trying all different versions of roo, sts, flex addon, and absolutely no joy, apart from the solution above which worked partially for me. Im not sure what else to suggest, heck I even did the exact versions that were shown in the 15 minute flex addon introduction videos from the spring sight and still no luck. I would love to use roo, obviously but I gave up in the end, the above instructions gave me the best results I had.

[leonardovarela]

I believe even the developers of flex roo are having trouble specifying which version of STS + Roo + flex addon is a good combination...
I have also downloaded STS 2.5.2 to try the 'stable', 'production' version with absolutely no luck, I've been doing this for more than one week now.... Moving my project away from roo

[MikeOliverAZ]

First I tried on my big machine, Win 7 Ultimate (64bit) with quad core and 8GB Ram, Java 6, STS 2.6 and the snapshot builds for flex roo add on and annotations as per above, first with 290 then 291. No luck and Roo shell would hang.

So I moved to a smaller machine Win 7 Ultimate (32bit), also quad core and 4 GB Ram, Java 6, STS 2.6. Before adding the flex add on jars I tested Roo on its own and AOK!

I then added the two jars for flex with snapshot build 291. It didn't hang, and I did the following steps:

// Spring Roo 1.1.3.RELEASE [rev 4404ffb] log opened at 2011-04-29 08:00:03
project --topLevelPackage com.corenttech.flex --projectName OneRooFlex --java 6
// Spring Roo 1.1.3.RELEASE [rev 4404ffb] log closed at 2011-04-29 08:00:08

persistence setup --database DERBY --provider HIBERNATE 
entity --class Rain --testAutomatically 
field string RainType --notNull 
field string Description
flex setup
flex remoting all --package com.corenttech.flex

I then tried it and http://localhost:8080/OneRooFlex/One..._scaffold.html

Showed the Flex screen, but not complete,

I think until someone can spend the time to get the kinks out, the Flex ROO add on is more work than it saves. The BlazeDS integration with Spring, coupled to Flash Builder Plugin to STS seems like the best bet for now.

[MikeOliverAZ]

It may not mean anything but when I did the flex remoting all it showed

A field with name 'RainType' already exists

[delgad9]

The believe I walked this road months ago...

I think until someone can spend the time to get the kinks out, the Flex ROO add on is more work than it saves. The BlazeDS integration with Spring, coupled to Flash Builder Plugin to STS seems like the best bet for now.

Actually you can do something better...
You can start with ROO 1.1.0M1 and the very first Flex addon published. Sorry I forgot the version. Create the project and then update to the latest Roo. Continue development using Flash Builder plugin.

This is the way I created-circa Sep 2010-following Flex app: http://pragmatikroo.org/gnc/gnc-debug/gnc.html.

A least you get the project setup and the back end stuff this way.

[MikeOliverAZ]

I REALLY want to get Flex ROO working for many reasons, so if I can help by showing what I did and the results, I will.

Best results I have had were with STS 2.5.2 and org.springframework.flex.roo.addon-1.0.0.BUILD-20110219.075648-225

I was able to get the Wedding Example to run, so I have high hopes.

Something is very touchy and it doesn't handle errors well. Here is the roo.log on a small sample.

Part 3
I think it has to do with the error that caused it to Undo everything with

A field with name 'ActionAttachmentFileName' already exists

Running flex remoting all --package ~.service then does NOT create the same things, leading to running it not showing any Entities.

So I tried

Created SRC_MAIN_JAVA\com\corenttech\care\service\ActionsService2.java
~.Actions roo> flex remoting scaffold --name ~.service.ActionsService2 --entity ~.Actions

Created SRC_MAIN_JAVA\com\corenttech\care\service\ActionsService2_Roo_Service.aj
~.Actions roo>

No Entities listed when I run it.

Since I do see the Rsvp entity listed when running the Flex Wedding example, I decided to compare the two projects thinking the difference will point to the problem.

CARE3_scaffold.mxml and FlexWedding_scaffold.mxml are virtually identical, except the package path.

So given the "entities" array list was the same and not displaying in CARE3 but displaying in FlexWedding, I assumed the CARE3_scaffold.swf was simply not updated. I deleted it and did a restart of STS.

I got

An internal error occurred during: "Initialize CompilationUnit Manager".
java.lang.NullPointerException

I also noted several Errors related to ROO Projects that I have deleted like

I couldn't seem to force the generation of the swf (probably just my ignorance) but I thought adding another Entity would, so

Again it threw that "already exists" and Undo of the service and .as

I also noted the presentation mxml was not generated for the ActionProperties Entity.

Running it again in the ROO Shell...

~.ActionProperties roo>

Now did not throw the "already exists" error and generated the ActionProperties presentation mxml.

But still no new CARE3_scaffold.swf

So I did a clean of the project and rebuild.
