Flex :: Spring Security Using Container Preauth
Sep 20, 2010
I've got the Spring Security preauthentication sample configured and working with JBoss. The next step is to somehow get the user information into a flex client GUI. What are some methods that will let me get the Authentication or UserDetails object that's created by spring-security on http access into the flex client? Since I'm logging in externally, I can't use channelset.login(), right? All the examples I've seen so far assume that the user logs in manually through the flex client, but the requirement is for container-based authentication. Using flex3, spring 3.0.4, spring-security-3.0.3

I tried asking this on the Spring forums ([URL]) but did not get a response. I'm working on a web application that has an (end user) user interface built in Flex and a management user interface built using Spring MVC. I'm trying to secure both interfaces and can get each one working separately, but not together. I'm using a snapshot build of spring-flex-core 1.5.0 with Spring Security 3.1RC1 and Spring 3.1M1
[Code]...
I'm obviously missing something but while the Spring Flex documentation describes how to configure a hybrid MVC+Flex application at the servlet level it appears to only consider security from the perspective of a flex-only application.

I'm using Spring, Spring Security, BlazeDS, Flex and spring-flex.I know that I can call channelSet.login() and channelSet.logout() to hook into Spring Security for authentication.channelSet.authenticated apparently only knows about the current Flex session, as it always starts off as false, until you call channelSet.login().hat I want to do: Check from Flex to know if a user is already in a session.

I'm having trouble with an AS3 AMF RemoteObject request that is hosted on App Engine. I have a crossdomain.xml file in the root of the domain, and also one at the remoting endpoint.Here are the contents of the root crossdomain.xml:
<?xml version="1.0"?>
<cross-domain-policy>
<site-control permitted-cross-domain-policies ="all"/>[code].....
Loading the swf file and testing it on my machine works just fine... I think that may have something to do with me having the debugger version of Flash Player. When I push it up to App Engine to make it public, other clients access it and get a Client.Error.MessageSend Channel.Security.Error error Error #2048 url: http:[url].......I am using Flex 4 beta, and the App Engine Python runtime. I have tried full wildcard in the crossdomain, and even accessing the data endpoint at a relative URL so as to avoid this error.

In a Flex Mobile project I have a simple itemRenderer where I'm trying to create an "bubble" texting effect, similar to ichat or iphone (just so you get what im going for). But if the text is longer than the screen it runs off, rather than just going down a line.
If I set Group thats holding the rectangle(to create the bubble effect) and the label to 100% it works and keeps it from exceeding the list containers bounds, BUT the group is always at 100% and looks bad, I'm trying to keep the "bubble" JUST AROUND the text.
Anyway so, at the top of my itemRenderer I tried specifying:
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" width="100%" height="100%">
And here's my layout I figured since msg_container has a width of 100% I was hoping bubble_lable_group would just not exceed that but...it doesnt...it just runs off. I tried setting a max width but that does not allow you to input percents. And just to say it 1 more time. I know if i set bubble_lable_group width to 100% it works, and keeps it from going off the edge, but then the rectangle "bubble" stretches all the way across and just looks bad.
<s:VGroup id="main_container" horizontalAlign="left" paddingBottom="10" paddingTop="10"
verticalAlign="top" width="100%">

I have a loop that goes through data from a book and displays it. The book is not consistent in it's layout so I am trying to display it in two different ways. First way(works fine) is to load the text from that section in to a panel and display it. The second way is to create a new panel (panel creates fine) and then add collapsable panels(nested) to that panel. Here is the code from the else loop.
else if (newPanel == false){
// simpleData is just for the title bar of the new panel
// otherwise the panel has no content
[Code]....
The error I get is: ReferenceError: Error #1069: Property panel4.4 not found on components.readTest and there is no default value.
I have tried setting the "name" property instead of the "id" property.

I should build a web application for back-office purposes and one of the main requisites is a good UI. On server-side I'll use Java very likely Spring framework, depending on what I'll be using client-side. I think to basically have 3 choices for client-side: a "normal" web application, meaning JSP pages, using JQuery framework. In this case, I will use full Spring's features, complete MVC pattern etc. I've been using Spring and JQuery for 2 years, so I know these techs very well. But I also know that it's quite complicated to realize some effects, much javascript code involved, specially when dealing with ajax calls and dynamic changes of page structure.
Flex with add-ons such as BlazeDs to integrate with Spring. I have no experience using Flex, I just read some articles and tutorial about it, but I really would like to learn something new :-) Google Web Toolkit, maybe with something like gwt-ext. No experience, but I really like to learn. It's plenty of support out there if I need, but I think I will struggle to maintain Spring MVC and GWT in the same project, I read that it's not so easy but there are a couple of patterns to follow.

Some background: I have a Flex app embedded in an HTML page and am using Flex to send a soap request to my Java backend that does some authentication depending on the username and password entered in the Flex form. If I enter the correct login everything works fine and the Flex app can continue making further requests. But with an incorrect username/password, an "Authentication Required" dialog box pops up in my Browser and my Flex app won't respond with its proper handler until I click cancel. I'd like to get rid of the dialog box somehow,

I have been trying to upgrade spring-flex 1.0.3 to 1.5.2 in order to check new features, i.e. Hibernate lazy fetching support in BlazeDS 4. I downloaded all necessary packages, changed dependencies in Maven for Spring (to 3.0.7), Hibernate (to 3.6.9) and Spring flex core (to 1.5.2). When I try to build and deploy application, I got NullPointerException which indicates cause in my domain class (at the end of stack trace):

I'm going to be using Flex 4 with Spring and Hibernate.Everything is configured and working. I know this as I can do simple queries, like listing all values in a table.Problem is when I try to perform a 'select' query, then I get all the values, as I was getting before, and not the specific attributes through Select query.I'm a beginner, so kindly overlook my lack of more technically sound words..but I don use them as I don wanna mis-quote.This is class used to store data coming from the MySQL database--

The reference doc ( here ) tells us to download the sample application: Included in the project distribution is a collection of samples called the Spring BlazeDS Integration Test Drive. This samples project is set up to be built with Maven and then imported into Eclipse for running the application via WTP.
The samples in question, must either be spring-flex-testdrive-spring3.zip which is linked to in the document or spring-flex-testdrive-spring3.zip based on the notion that this is release 1.5.0.M1 (docs and samples).After I configure maven as described with the proper environment variable:
MAVEN_OPTS="-Xms256m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=256m"
I then execute (per instruction) the command to install: mvn clean install from the extracted samples directory (in my case C:spring-flex-testdrive ), I receive the following error:
C:spring-flex-testdrive>mvn clean install
[INFO] Scanning for projects...
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]
[code]....
I have managed to get a "Spring BlazeDS" application working (with Flex), but now I'm at the point where I need to implement security, and if the samples would compile and run correctly.

Now how to drag any circle from any Big circle to other side. Or it could be like any two container having circles, then how to drag and drop circle?
For one circle i am able to do drag and drop.But I want one Big circle on left hand side and one big circle on right hand side .And small circles with class names will be in these big circles.Now i want to drag and drop those small circles in big circles.Big cicles should not move. Even i have tried this code in actionscript

The Spring BlazeDS integration (in our cases 1.0.5M1) allows us to define MessageInterceptor instances and register them in the message broker. what this mechanism should or shouldn't be used for?
From the API documentation I can see that the framework itself uses interceptors for Spring Security integration. We were thinking of using these interceptors as a way of enforcing our own special kind of security (we track our users using our own services in the application context), where a condition is evaluated every time a message is sent across the wire.

I'm trying to figure out the best way to leverage a vanilla HttpServlet from a Spring-Flex (with BlazeDS) project I'm working on. My team has an HttpServlet that they've used in the past (that some other team built) that processes a request given some key/value pairs passed over HTTP GET. I want to use this HttpServlet class to do the same work, but I want to call it in Java, when my Flex client invokes a method on a Service. Ideally, the class invoking the HttpServlet can use the standard @Service and @RemotingDestination annotations (see here).
So, this is the HttpServlet:
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.HttpURLConnection;
import java.net.URL;
[Code] .....
How to write my @Service class. I've tried going down a few different roads, but haven't had much luck. So far, I've considered and come up with secondary questions on the matter (but I've yet to work out the solution):
Do I need a @Controller for this sort of work?
Do I need a Servlet Factory?
Can the HttpServlet be a Spring managed bean, and call the ASP page another way?
(I like this idea least) Should I call the HttpServlet from Flex, and leverage logging and data the Servlet needs with a Remote Object?
The reason for my stubbornness in wanting to do this from Java is that I want to do some logging, and maybe leverage some other Singleton beans in the scope of the @Service class. However I work this out, I want to be as close to "Best Practices" as possible.

I have a spring BlazeDS integration application. I would like to log all the request.I planned to use Filter. In my filter when I check the request parameter. It does not contain anything related to the client request. If I change the order of my filter(I have spring Security), then it prints some thing related to spring security.I am unable to log the user request.

So as the app. will be a dashboard a lot of the application will consist of publishing data to the flex client to update all the monitoring views. So there will be limited database activity ie: insert/update/deletes.

In my attempt to learn flex remoting I came across thisflexService.getRules.addEventListener(ResultEvent.RESULT, loadRules);here flexService is a remote java object . me that when esultEvent.RESULT will occur. On studying about ResultEvent in AS document it states as The event that indicates an RPC operation has successfully returned a resultSo keeping that in mind my guess is ResultEvent will be fired when flexService.getRules method will successfully return a list of object,where flexService is object of remote class FlexService having getRules function which returns list of object, Can any one please tell how exactly it works

I'm trying to implement a simple application which uses Flex on the front end and a Spring/Hibernate application on the back end, with communication between the two going over a BlazeDS channel.
I'm seeking direction as to the best and/or simplest way to approach this. I have the UI set up in such a way that the user is presented with a file chooser in which they pick the image file they want to upload. When this is chosen and submitted (as a form submission) then the server side should receive the image file data as well as some related metadata such as a description and date, then populate a Hibernate entity/POJO with the image file data and related metadata, and then persist the entity/POJO into the database.
I have found some examples of how you would do a file upload and download using servlets here and the FileReference class (here and here) but these don't appear to address the problem in a way which leverages BlazeDS and/or Spring/Hibernate. I want to put the image file data and related metadata (description, capture date, etc.) into a value object within the Flex application and then send this over BlazeDS to a service provided by my Spring/Hibernate application running on Tomcat. In this service I want to extract the image data (both the actual JPG/PNG/GIF data and the related metadata such as description, etc.) from the value object sent from the Flex app into an entity/POJO which is then persisted via Hibernate in my database.
Can this be done, and if so what's the best way to go about it? Am I mistaken in assuming that if I use BlazeDS then I am somehow bypassing the need to provide HTTP-based services such as servlets on the server side and instead I can use my Java services as "RemoteObjects"? Is there necessarily a one-to-one mapping between Java POJO/entity class and the Flex value object class when making this sort of transfer? If so is there a tool which creates corresponding Flex value objects from Java POJOs or vice versa.
Update: Some code to make this more clear:I have this as my value object in Flex:
package valueobjects
{
import flash.utils.ByteArray;
[Bindable]
[code]....
When I set a breakpoint in the method above and look at the image variable it looks to be empty, so I'm assuming that the transformation from the Flex value object to the Java POJO did not go as expected and that there's more to it than just adding a RemoteClass alias in the Flex value object class.
