How do i receive flash objects in java? I'm trying to create a multiplayer game, i've chosen sockets to handle this and Java as the server. So far i made myself a client/server already. And it works when sending as3 objects. but, not the way i want it! I made a class in AS3 and in Java that represents the object to be sent. AS3 Class 'Package'
[Code]...
I want to a framework to pass objects between Java and AS3 using sockets. It should be something with good performance (not XML, JSON). I have looked into AMF but all of the tutorials are very complex and not about what I need. I have used java to java serialization but I can't find any tutorial about Java to AS3.
View 4 RepliesI am attempting to connect to a python twisted socket server with Flash using XMLSocket. The connect works fine, and so does the receive. However I can't send data to the server. Is there a specific format I should be using? The reason I ask is because I couldn't read any data with the XMLSocket until the data was in the form "something", that is, the data string had to be valid xml followed by the null character. Is there a trick to sending data?
I don't think this a cross site security problem, because if it was, I believe I wouldn't be able to connect or receive. I am able to connect to the server using telnet and a java client without issues. EDIT: I figured it out, the problem was my server needed to have the data sent to it end with"
I'm bothering with Java-Flash communication. At the beggining, I used XML Socket Class, which was pretty easy to implement and my aplication comunicated very well.However, my program will monitor behavior of many users at the same time, so parsing and sending large xml files could overload Server. Thats why I used Socket class and AMF coding instead. After tough hours of implementing it, whole application seemed to work. Unfortunently, after couple of tests it apeard, that Socket was slower than XML Socket! I have no idea why, because in theory binary messages should be much faster than xml. Could you help me solving this issue? Below I pasted my code for both Java and AS3.
This code sends basic variables from class object and are received the same way (it can sound bit complicated compared to just sending whole object, but for various reasons is the only way).
1. Java client (java server receives data from different sources and sends it to flash):
Code: public void sendMyPosition(MyPositionMessage message, Socket sock) throws IOException
{
synchronized (sock) {[code].....
2. Flash server - new data triggers socketDataHandler which receive it with readReasponse function. First int describes which kind of message was send, although there is only one at the moment. I've deleted some handlers couse they seemd irrelevant this case. Whole AS Class is attached as a file.
Code:
public class CustomSocket extends Socket {
private var currentMessage:int = -1;
private var message:Object = null;[code]................
I'm building a multiplayer card game using Flex on the client side and Java on the server side and I wanted to know if I must sockets and the accept method in order to connect users to the server for in order for them to join a game room or create one or to chat.In the past I've learned how to build a game server which both sides are JAVA and connection was in sockets but now days the client side will be in FLEX which has few ways to connect to a Java server (XML,SOAP,BLAZEDS(AMF)) and I find it hard to understand how to write the Java server in order to do all the features of a game server,especially managing the rooms and sending data back to the users.
In the sockets way, when a user was connecting to the server and he had opened a room, this room was opened on a thread and who ever was joined that room then he was connected to the same thread and sending the messages to the right place was easy, so the problem is understanding how to do the same using SOAP or BLAZEDS.
I am writing a online game with flex and java server and I have a big problem. In normal case, my game run smoothly but some time the clients can't receive the command from server. I found that if server send message too fast or client is doing something when server send message, the game client can't detect for a new message so my game is freeze. I only tested with 4 clients and I don't know what happen when thousands clients online in the same time. So terrible :(. In the game client, I use one EventDispatcher class to dispatch any command from the server. Do you have any solution to warranty that client must receive any message from server when the connection is still alive or server must know if client received the message or not. I use flex 3 with Socket (binary) and Java QuickServer.
View 1 RepliesI 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 RepliesWe are in the middle to evaluate the technology choice to re-design an operator console application. The operator console as a hosted contact center has the abilities to queue the inactive calls, and hold, answer, transfer the active calls.
The legacy operator console used Java Swing. We want to use the latest RIA technology (Flex/Silverlight) to retire the legacy one. But the question is Flex/Silverlight can implement the functions like hold, transfer the calls? Based on my experiences, Flex can listen Java socket to receive XML data? Does it work well to receive voice data?
I am using Flex 3 and make a call through a RemoteObject to a Java 1.6 method and exposed with BlazeDS and Spring 2.5.5 Integration over a SecureAMFChannel. The ActionScript is as follows (this code is an example of the real thing which is on a separate dev network);

If one doesn't have the source code, the only to test is to send keystroke and mouse move so I found this product but it's not free and opensource price is not even known :([URL] Squish supports automating interactions and testing non-HTML/DOM elements, that is, native objects, which are embedded in a web page. This is done at a fairly abstract level, which means that mouse and text input can be recorded and replayed.
In addition it is possible to inspect embedded native objects with the Spy tool and to insert verifications for these native objects. All of a native object's public properties can be accessed in test scripts.
Right away i just try to explain my problem: Using BlazeDS i got the following Javaclasses:
[Code]...
Then i got a Flex service class calling BlazeDS and executing the getCategories java method. Since Flash dosn't seem to understand typed arrays, the result from that method which i get back in flex is a simple array of untyped objects (the mapping dosn't seem to work here, even tought the class category exists in flex and has the same properties).
thats the first thing. but however, i'm converting the untyped objects manually into objects of the category.as class. the second thing is that categories have child-categories within the java object, which are also ArrayLists of the type category.java. the problem about that: my result event object only contains the first level of categories, looking into them the children are allways null. i dunno why they are empty, since they ARE part of the java object category.
and the third thing (the strangest by fast), you maybe noticed i named the properties of the category.java class strange, like idCat and nameTest instead of simply id and name. why that? because the property names of my flex result objects dont seem to change when i change the java objects properties names (result object properties are named "id" and "name" but the java class object properties are named "idCAT" and "nameTEST"). that it REALLY strange, since if i set the properties, like you see at nameTEST = "TESTNAME" it IS recogniced by flex, only the proertyNAMES dont seem to be recognized at all.

View 2 RepliesI will try to give as much detail as I can. I am creating an CRM application using Flex(Cairngorm 2)/Java/Hibernate. The basic problem I am having is this: I have a Customer class in Java that has an ArrayList of Address classes. I have a Customer class in Flex that has an ArrayCollection of Address classes. When I make the remote object call for a Customer I get back a Customer object in Flex, but the ArrayCollecion objects have a data type of Object instead of Address. If I try to call for a List of Address classes I get the same result. If I try to call for a List of Customer classes I get a list of Customer classes in Flex. Using tomcat 6 with the following jars:

They all move in unison, but by my terrible reasoning, all objects in the particle array should receive different velocities. Is there some much more efficient way to achieve this effect? If not, tell me what is wrong in my for loop. Update is an on enter frame function, by the way.
For List we have ArrayCollection in flex.But what when we get an object such as HashMap from Java..And we want to map it to Flex?
View 1 RepliesI'm using a java-backend with a flex frontend. And when i want to use a labelfunction it doesn't load the indepth properties such as a value object, it's like it is lazy loaded in the flex side, I'm sure it is not comming from the backend because i've checked it overthere.I've got it also in datagrid's that it doesn't load all the values at once. [code]I ask at my back end get all John's, the backend gives me all John's which contains the Doe's. Now At the flex side I fire the result event from the callresponder when i receive that data. But still it can't acces the doe's into the Johns, the doe property of john is still null. When i ask it the second time it nows about the doe's, so it looks like lazy loading in a front-end way..

Is it possible to drag objects outside the browser window in order to implement file/directory copying from webserver to desktop?
UPDATE: added more tags in order to broaden the choice of methods.
I have 2 java classes that are the same (imagine the getters and setters):
class ScheduledEvent {
private String eventName;
private List<eventValues> values; [code]....
Now there is a reason why there are two classes that are the same.When something is "scheduled", I should get the ScheduleEvent object and when an event is started, I should get the StartEvent object.And depending on the object I get back, I do different things.My problem is that, on the backend, it will send me the ScheduleEvent object, but once it got to the flex side (via BlazeDS), it becomes a StartEvent....
At first, I thought it's because these two events have exactly the same variables, so I tried changing ScheduledEvent by adding a dummy variable (String foobar) but that didn't seem to make a difference.
EDIT: I'm using BlazeDS messaging system.That's why I am not using "one java method call to one responder" approach. So, in the message.body, I should be getting ScheduledEvent but I keep receiving StartEvent. I'm wondering if it's because the two objects have the same property and BlazeDS doesn't know how to map them correctly... I even put a break point in the java service layer, to make sure that the appropriate object is being sent back and it is... But by the time BlazeDS serializes and deserializes it to the flex side, it is now a StartEvent.
I have a collection of Objects in an ArrayCollection in my flex page.
What is the best approach to send this data to a Java Servlet?
The object in the ArrayCollection is a VO that consists of an id and message for now. I want a solution that is scalable in case more properties are added later on.
Is it possible with actionscript to create objects then when sent through XMLsockets can be read by Java's ObjectInputSteam?
View 1 RepliesI've knocked together a Java/BlazeDS server which creates a generic GridBean object. This GridBean contains:[code]I then created a Flex app that uses a RemoteObjectServiceWrapper to call my java server, grab the GridBean, create some DataGrid columns from the columnDefs and then set the dataProvider as the list of objects. Ok so far, everything renders.Now, what I'd really like to do is: set up some kind of event handler on the flex side so that if my item/object is edited in the datagrid, I fire a message off to java saying 'edited this field on this item'. The end goal is to have a nice generic way to render any list of objects from Java in a flex datagrid.

I'm using BlazeDS to remote some Java objects that I'm consuming in a Flex application. I'm getting a type coercion error with one of my classes that I can't for the life of me figure out. I have other classes that are working fine using the same data types, and I've gone over my mapping a dozen times. I'm following all of the necessary conventions for getters and setters as far as I know...
Anyhow, my question is: how can I debug this problem? Running the Flex app in debug mode spits out some generic errors to the console that don't really help much (TypeError: Error #1034: Type Coercion failed: cannot convert Object@5d1d809 to valueObjects.SomeClass.).
I need to develop the HTTPS application using Flex and Java. But i have idea about remote objects or HTTPServices. which one is the best for developing HTTPS application.
View 1 RepliesI am working on an application that is near the end of its development cycle and has mostly passed user testing. We recently realized that having flex convert dates to the client's local timezone is not desired, as all of our dates are in EST and contain no time data. Since BlazeDS sends dates in UTC, this results in the dates being converted to the day before in timezones west of EST.
The best solution is to go in and refactor all dates to adjust for the timezone offset, but that is just not doable at this stage. Since all dates in our application don't care about time, I would really like to be able to intercept all Date objects that come across BlazeDS and adjust for the timezone offset.
I'm developing a webapp with Java backend and Flash (pure ActionScript) frontend using BlazeDS. I'm using the RemoteObject stuff to send objects, using custom serialization, where I need to implement Externalizable (Java) and IExternalizable (AS) interfaces. This works fine so far.
But now I need to send objects from Java to Flash, whose classes are generated with JAXB/XJC. Of course these generated Java classes don't implement the Externalizable interface, so it seems that I can't use my approach here. One possibility seems to be writing a XJC plugin which makes the classes implement Externalizable. But this looks like a tough job...
I am working on an Adobe Flex front-end with a Java back-end using JPA for persistence. he protocol I am using is remote objects (AMF) implemented with BlazeDS.I started out with a service-facade and entity DAOs, but without any specific DTOs. The same POJOs, the domain objects, were passed in the service-facade as those used as DTOs passed to the Hibernate DAOs.However, the latest few days I have been thinking whether this is a good approach or not. The latest article on the subject I read was this one:Interesting JPA Pattern blogThe situation:Say I have POJO Book with a unidirection ManyToOne relation with the POJO Category (i.e. each book may only be associated with one category, but the same category may be associated with many books). I see some alternatives:Alternative 1:I expose a method/operation addUpdateBook(Book book). In the implementation of this operation I add/update both the book and the referenced category.
View 1 RepliesFDT can do it, but half the time it times out and needs to be restarted on renaming some objects. Can Flash Builder do this?
View 1 Replieswe have a client/server app (Flex and Java) that uses BlazeDS to do remoting. This allows us to exchange and map types between client and server. For some reason a User type we are retrieving from the server is not sent as "User", but as "User_$$_javassist_x", where x is an integer.
The other types we are sending over all work fine, even the User type used in a different service class.
