I am working on a server push from Java to Flex. But some how the MessageBrokerServlet is not getting initialized, seems like it is calling a method from: flex.messaging.config.LoginCommandSettings.setMatch() Eventually I found out that this method indeed does not exist in that class (LoginCommandSettings). I there something else that is going wrong?
[Code]....
Since my service, I would like to push data (messaging).
@Service
@RemotingDestination
public class LoginService implements ILoginService
{
[Code]....
With this implementation, nothing to do ... clients receiveid nothing.
So, how I push data from a service like that ? Is it possible ?
I am using BlazeDS for data-push feature in my Flex application project. From the official tutorial, Getting started with BlazeDS, it shows messaging example with producer/consumer from API. but how can I implement server side which doesn't need to be invoke from Flex client, but from within server-side instead. I got some idea but I don't know how to do because I'm a Flex developer, not Java developer In Google, there's a tutorial show about I need to extend ServiceAdapter class in Java-side, which extends Invoke method. Do I need to extend other class instead of this to do what I want?
View 3 RepliesMy Flex application (SWF) initialization takes 25 second to load 1.6mb SWF in widescreen monitor. The same SWF loads pretty fast (3 Sec) in Flat panel monitor 1024x768 resolution. What is the reason for +/- in rendering speed , +/- in CPU utilization on different monitors , screen resolution.
note: my internet sepped is 10+ mbps broadband.
to point out some good tutorials on creating applications in flex that are don't have UI's?Actually, it looks like all I really need to know is how to call afunction upon initialization of the flash object. I tried the creationComplete attribute, but it doesn't work in browser.
View 2 RepliesSo I have a PHP proxy that gets information from a website. Let's say the proxy gets the information from (www.example.com). It checks if the number of lines returned is the same as before, if not then there are more lines, it counts the difference then it need to push this information to the Flex client saying that it has new information, (x) more lines have been written.I am not really sure how to do the push mechanism on the php proxy because I am not sure how to actually push from the proxy to the client, never done it before.
View 2 RepliesI want to push data to flex clients. I am talking about anywhere between 5000-15000 concurrent users, need to get data every time a currency is changed so that means lots of changes for lots of users.
I have been looking into WebOrb.net, but the performance seem very poor (100 users concurrent) for a product so pricy (we purchased a license).
So, I have to look into alternatives, I know there's fluorineFx but it seems no one is really using it for products and it lacks in examples and documentation.
My question is: what products can answer my needs (.net backend) and what are the performance I can expect out of these products?
I have a flex UI which communicates with server using spring blazeds. I have a very typical requirement of Live data streaming on a panel in UI. Requirement is like this, We have an object say, Person and server keeps pushing its data on blazeds message destination where UI panel consumer has subscribed and hence user can see this live data in a panel. User can open multiple panels in same browser to view data for different Persons at the same time (e.g id=1,2,3 respectively). There can be multiple UI users who may be viewing the same data for person id=1 at a given time, lets say.
Basically I want to separate data between UI panels. UI panel opened for person id=1 must not display data of that for person id=2. I am doing this using headers-selectors, but apparently I found out that the differentiation to select and display what data happens on UI which is causing performance issues. I learned that using subtopics may improve performance. But, before proceeding for it, I want to know, will UI browser end up in receiving data irrespective of subtopic assigned to data and then consumer will decide to accept it or not?
We are planning to make a POC for Desktop Alert application. We will have a desktop AIR app that will connect to a Java Server. The server will need to notify Desktop App when it has a notification which will be displayed on the screen.A couple of options that we have discovered are :
1. Keep a persistent connection between the AIR app and the Server, using some sockets and listen to any changes.
2. Poll the Server at intervals to check if some new data has come.
Since these options don't seem optimal (persistent connection) or seems performance wise (polling) better.
Can Flex be used for a desktop application whose business logic is written using Java? Everything I've read about flex uses a remoting or http protocol to communicate with the backend via a J2EE server, so I'm not sure how that would work for a desktop app (unless an embedded j2ee server was running in the app).
View 4 RepliesI'm just learning about Flex and I'm loving it. Unfortunatly I still have to make the decision on which RIA technology to use and its dependent on, among other things, from the following case: How can we wrap a java applet around a Flex application? More specifically, I would like to wrap/integrate NASA's World Wind applet in a Flex panel, similar to what Adrew Trice did with the Google Earth API.
An alternative would be id Flex would support direct access to the 3D hardware through OpenGL or DirectX. But I do not think that that is the case yet, not even through AIR.
Need to execute an external EXE from either a Java web app (running on Glassfish on Windows Server) or from an Flex/AIR desktop app.
View 2 RepliesWhat's the best way to secure a Flex-BlazeDS application? I've googled it an several solutions came up.UPDATE after question from jsight:Flex would login, so on the RemoteObject I'll set Credentials I don't know if there comes authentication and authorization with BlazeDS (WebORB for instance does and WebORB looked at BlazeDS for their product) SSL not needed 've seen some links on the internet talking about spring security, so I'll check that out.

I am struggling to come up with a way to efficiently manage Flex entities that have a many-to-many relationships between their JPA/Java counter parts.[code]Both of these entities can exist independently of each other and both have a 1:M relationship with the other. The relationship is not really owned by one side or the other.Within the application there are Flex UI's that sometimes want to see viewers based on movies and other UI's that want to see movies based on viewers.Currently both the Movies.Viewers and Viewers.Movies collections are lazy loaded by JPA which works fine. The problem is that every time I ask a viewer for it's list of movies, then they all get sent over the wire and then within Flex I end up with a bunch of Movie objects that (often, not always) duplicate the ones I already have there.
It seems inefficient at best and could likely cause errors if the duplicate objects are not dealt with.In my real application I have tons of these types of relationships all over some very large object graphs.It almost seems to me that the lazy loaded object collections need to be turned into eagerly loaded collections of foreign keys which are used to explicitly load objects on the Flex side of things. But this seems like I am writing a JPA provider in Flex! Is the correct answer to never store state in a Flex application? (Yikes)I should add that all my value objects have a UID that is created on the server side, so I could somehow use that to find/remove duplicates on the Flex side. But how?
I have a great idea and I want to build a flex application around a .jar file. Is there a way I can go by embedding a jar file into the flex application?
View 1 RepliesCurrently we are in the design phase of an application that will allow two users to communicate with each other using chat and video (with audio), the application is a web application that currently is a java web app with Spring and hibernate, but we want to incorporate video and chat between two users and we are evaluating the options to developing it, so far we have two choices, either develop a Flex UI that leverages its video and chatting capabilities through Red5 or something like that and communicates with the Spring app using BlazeDS or a completely java based approach using (maybe) JMF and/or applets to achieve the video and chat interaction. The question is, which would be the most scalable approach to develop such an application?, what would be the approach that is the least intrusive from the end user perspective?

View 2 RepliesI know it is possible to develop a full flex application using AIR for android but what I need is to embed a flex component into an already existing classic java android application.
I found some flash players in java but they all either require a JFrame or include of specific windows dlls.
I am looking for an approach that will allow me to (somehow) dynamically pass the server name, server port, and web context to my Flex client so it can create a ChannelSet for it's RemoteObjects to use. These three properties are, of course, readily available to my Java server-side code so I just need a way to get them to the client.
By default, Adobe says you should compile your Flex application against the server configuration file "services-config.xml". This is a highly inflexible practice that Spring says should be avoided (I agree).
One popular approach is to use Flex's http service to download an XML configuration file. I like this idea, but I don't want to hard-code an XML file and keep it inside my WAR file. Is there a way to dynamically generate this from Java code?somehow use flashvars to pass the properties in from the containing HTML page to the SWF file. But again, I don't want to hard code them into the HTML page. Is there a way (maybe with Javascript?) to dynamically set the value of these when the page loads?
I have an Application consisting of a Java Server part and a Flash/Flex client, both communicate via BlazeDS. In order to have the same typed Objects on both sites, I use the GAS3 code generator (used by flex-mojos).But now I am facing the problem of handling nullable Integers. The problem is that I have an Object (A) which contains a foreign key ID which is reference an optional Object B. - But I only send the ID to the flex client.On the Java site it is easy:
class A {
private Integer bFk;
getter/setter
}
But on the flex client side, bFk is of type int. And a Flash int can not be null. So the remoting mechanism converts the Java null Integer to 0. After sending it back to the server, the Java bFk becomes 0 even on the Java side. - That is not acceptable, because I need to separate 0 and nullMy first workround is using not a Integer on the Java side, but an new Class NullAbleID, which works a bit like a wrapper/adapter, that wrap an internal int where -1 represent null (I can use -1 for null, because real id will be negative). But when I would using this it means I have to replace all Java Integer ids, by this NullAbleID class.
I have two applications: a client in flex and a server in Java. When I deploying the application inside flex builder with the tomcat server inside as well, everything works fine. But now I'm trying to deploy in apache tomcat outside the flex/eclipse builder and I have a problem.I think the problem is with relative/absolute paths but I do not know how to resolve it.In my Java application I have to access a database and a get a file from it. I use a properties to set a path where I want to download that files like this:pacs.ruta=C:\resources\And then I need to access to that file so in use this code:fin = new FileInputStream(pacsRuta+""+f.getName());where f.getName() gives me the name of the file so I get the path of the file with the path I set in pacs.ruta and the files name.
I do not know why it does not work. I tried to put pacs.ruta=/resources/to associate with a folder in my application but It does not work.Could someone give me an advice? Do you think it is the problem? Because the whole application works fine deploying in a tomcat server outside the flex/eclipse builder but when this code is called the application does not work.
