Very good introduction to work with Java and FB4. I encountered a few problems, but they seemed to be covered on Jira. One thing still was left unexplained; adding the Flex nature and generating the HTML-templates were missing after invoking "flex setup". That's funny because they seem to be generated on the video.

Hi Jeremy,

actually, I am using STS with Roo Shell window. After "flex setup", I must manually enter to terminal and excute "mvn eclipse:eclipse", when it starts to download the Flex jar-files from Sonatype's repository. After this visit to terminal and refreshing the project on Eclipse, I get the Flex nature, but I still need to recreate the HTML-templates (using the Problems' window Quick fix).

Tero are you using the Roo 1.1.0.M2 or M1? I also come across this problem but only when using Spring Flex add-on 1.5.0.M1 with Roo 1.1.0.M2 and STS 2.3.3.M2. The html-template is generated correctly when using M1 versions of Roo and STS. But at least there's a manual work around for M2.

Hello Jeremy Grelle,

Thanks! for the nice video tutorials.

When I deploy the war on Tomcat it works fine, but When I deploy it on JBoss 4.2.3GA having some problems

I am currently trying to follow your video exactly but with no success. I am using STS 2.3.3.M2 and have tried it with both roo 1.1.0.M2 and roo 1.1.0.M1. I am using Flex 4 plugin. Can I have a copy of your simple example and see if I import it and run it? Does your example run using the "Run As Server" within STS. I know after running this I have to "run As Web Application" using Flash perspective. The GUI comes up successfully but I can't create an Artist or anything. I don't have tomcat installed on my new laptop yet so haven't tried running it as you did using tomcat 6.0. The error I get is "cannot invoke method list" and "cannot invoke method create".

Hi. same problem here using sts 2.5.0 M3
has anybody solved this.
Any help will be appreciated.

Where can I get a copy of STS 2.2.3.M1 (Eclipse 3.5.x based probably) Mac carbon? I called no joy with STS 2.5.0M3 (Eclipse 3.6 base)

Hi you all.
I have some news regarding this issue – I finally got it working. Here it is how (I think….there is something strange I cannot completely understand):
- I followed the suggestions read here, and somewhere else, on how to properly configure the services-config.xml, so I removed the "/app" part from endpoints and configuring the amf channels with no polling.
- I launched the project from command line with the "mvn tomcat:run" command. This somehow compiled the flex frontend against my services-config.xml (I believe), as after this I can successfully launch my project from inside STS tc server as well. Really looks like the STS.2.5.0.M3 is missing something when facing flex integration.

Maybe someone could analyze this deeper and find the real reason behind this.
But for the moment, doing some strange voodoo, the flex-spring integration seems to work eventually.

hello, what is flex addon and roo version for sts 2.5.1 ?

Still can't get this run… it's now 7 days when i keep trying do anything with spring roo… I don't know what to think about this tool… it's buggy? crappy? or what?! I'm using STS 2.5.1, Spring Roo 1.1.0 Relase, Flex Addon from above link.
First of all Roo Shell in STS doesn't work (want execute any comand, hangs whole sts)…
I'm using Mac Shell to use Roo…. but every time i'm founding new project from scrache, i'm getting different errors..
From 2 days I have problem with dependencies, after resolving it, i have 404 in browser after running this scaffolded project.. from one hour I can't recognize flex-config.xml… it's something terrible… I'm using java 6 mac edition – maybe this is why this wan't work?

It does not work with togehter

sts-2.5.1.RELEASE
and with flex addon
spring-flex-1.5.0.M1\dist\org.springframework.flex.roo.addon-1.0.0.M1.jar

nor with
org.springframework.flex.roo.addon-1.0.0.BUILD-20110102.020008-185.jar
–
Tested on Win7 JDK 6.
It completely freezes when I click on create new roo project after copied flex addon to boundle folder.

I can't find the flex link in the flash builder 4 plugin directory. I am trying to replicate the instruction step by step but I can't seem to find com.adobe.flexbuilder.feature.core.ns1.link

I couldn't find the old download for sts-2.3.3.M1 so I just used the most recent version. The problem is that newer versions of sts don't support spring-roo-1.1.0M1. I have to use spring-roo-1.1.0M1 because that's the only version that works with the Flex add on from spring-flex-1.5.0.M1. So I'm using the command line for roo. Then I go over to sts and just refresh the project to see the changes. It's not the optimal way to do it but essentially it's the same thing.

To get the Flex plugin for STS just download the Flash Builder 4 plugin installer from the Adobe website and run through the install wizard. It will ask you which Eclipse (sts) installation you'd like to apply it to. It's not necessary to copy the com.adobe.flexbuilder.feature.core.nl1.link file since the installer will do that for you.

@Jeremy Grelle

The reason I'm using spring-roo-1.1.0M1 is because of the Flex add on. The only combination that seemed to work for me was spring-roo-1.1.0M1 and spring-flex-1.5.0.M1.

Yes, the FB4 plugin now auto installs the .link file in the STS dropins folder.

I'm now having an issue creating the numberOfMembers field for the Artist entity. I use the below command as stated in your tutorial:

field number –type java.lang.Integer –fieldName numberOfMembers –notNull –min 1

When I execute the command I get:

Command 'field number –type java.lang.Integer –fieldName numberOfMembers –notNull –min 1' was found but is not currently available

I think I've fallen out of the step-by-step project creation process. When I execute 'hint' I get the standard Welcome to Roo info. How can I step back into the project creation process without having to create a new project?

Thanks.

@Jeremy Grelle

Thanks for the link to the forums. I've resolved all my issues.

Nice post. I was checking constantly this blog and I am impressed! Very helpful info specifically the last part I care for such info much. I was looking for this certain information for a very long time. Thank you and good luck.

It always surprises me how many maven based project fails for users that try to do 'exactly' the same as on a screencast.

I have come across many maven based projects, but properly I lack the understanding, or maven acts up on me and everybody that responds to a blogpost, except for the blogposter
Really, I am not impressed by this tool (and maven) I can do exactly the same with a couple of remote objects calls from flex and some Pojo's and Blaze-DS.

i think though maven is nice once you read through millions of internet pages, but for the average Java Jo maven is just a pain in the rear and forces you to much to do things the maven way.
