Flex :: Connection Between Java / Using Blazeds Returns Error #2048
May 4, 2011
I have been developing an application(a website to be more precise) which consists of a flex front end which is constantly sending and receiving data from the back end which is programmed in java. The connection between the two components is being done through blazeds. This worked fine while I was running it locally, however when I uploaded both sides of the application to a tomcat server(online) the following error is being returned when a connection between the components should occur:URL...I have read around about this error and many seem to getting this error when making connections between different servers, unlike here, where the connection is occurring within the same server.

i got a problem with 'Security error',it happens when i try to connect my XMLSocket (Flex) with my Socket (Java)i have a domain:
alucardeck.mine.nu
i startup my apache tomcat 6.0 and in ROOT folder i have:
policyFile.xml and crossdomain.xml
(i had a doubt about what is the correct filename so i created both)both files contains:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />
</cross-domain-policy>
well, yes, you can access using the default port 80, as it should be.(but probably my server will be down when u try to access it)so here is what i do: i run my Java server application.there i open 1 socket in port 19809.(i already tried with port 843 too) then, i run my Flex application: [URL]also i tried to run it in ROOT folder..the XMLSocket class is instanced like this:
xmlsock = new XMLSocket();
// add all listeners
Security.loadPolicyFile("http://alucardeck.mine.nu/crossdomain.xml");
// also tried "xmlsocket://alucardeck.m....
[code]....
i also notice when i start my Java Server application with 2 sockets listening ports: 843 and 19809, i notice Flex first try to connect to 843 and then 19809, and in both sockets i reply with that String from before.

I have a simple IRC socket that is used to communicate with servers for a web-based IRC client. Unfortunately, attempting to connect to a network results in a security error. I read up on sandboxes and their appropriate permissions, and then used Security.sandboxType to get the sandbox of my socket, which came up as remote. After reviewing the documentation, I still don't fully understand how I can enable my socket to connect to a remote IRC server. I tried Security.allowDomain,

I have a swf file "website.swf" on my desktop computer, in the www directory of my wamp server. The website loads the swf file fine.I have one textbox that i want to be able to load all the different contents of my site depending on the page, and in the same directory, I have all the different txt files (i.e. news.txt about.txt portfolio.txt etc)Now, when I'm running the swf file in Flash CS5, it makes me allow it and then works fine. However, once I publish and put it on the server, and then go to the website it returns "Error 2048". I've tried doing the crossdomain.xml suggestions to no avail.

When i make a small change in Flex code (eg, reposition of a button...anything), and run the project on server, it does make any change on output. Actually it depends on my luck... because it makes change in output randomly.what is is happening? tried rebuild, republish, clean , restart server, restarting the IDE, restarting the computer all available feature i could think. Also, i created a simple flex project on IDE and compiled it..... everything is compiled and displayed on output.

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.

i don't know why tomcat doesn't find the class of flex.messaging.endpoints.AMFEndpoint that is used for my-amf 'URL...'. all works well in the emulated server that flex has.

Im trying to make connection from flex to java and from java to mysql. I managed to connect to java, but having error that class not found: com.mysql.jdbc.Driver. But i downloaded mysql.jar, included it added to library, and connection works when i testing it from clipse scrapbook. Dont know what to do, i spend last couple days on this.
Class.forName("com.mysql.jdbc.Driver");
String username = "username";
String password = "password";
[code]....
Basically the solution was simple. Everybody keeps saying to put jar into lib folder, so i done it, but i wasnt realised that i have to put into my servers lib directory, not app lib directory and this miserable mistake cost so much. Anyway i hope this will help for some newbie like me.In this particular situation im using red5, so i putted it into my red5 dist/lib directory and "surprisingly" its started to work.

I'm starting a flex+blazeds project. First I coded some server classes, and modified xmls (in WEB-INF). Now I want to test it with client. There (in Flash Builder) it's needed to specify path to folder where server lives. The problem is that I cannot find it. In the same time [URL] is found in browser.

I using messaging in Flex-BlazeDS. When the AIR client starts it connects to a destination and a specific subtopic. During runtime, the user can use a combo box to subscribe to different sets of live data coming in, this combo box change event changes the subtopic by:
messagingConsumer.subtopic = subtopicComboBox.selectedLabel;
messagingProducer.subtopic = subtopicComboBox.selectedLabel;
messagingConsumer.subscribe();
A message is then sent to the server with the new subtopic name as well so the server knows to send to a new subtopic. This whole mechanism seems very glitchy and I'm wondering if anyone else has tried this and succeeded? Most times it works the first time and the after that either the messages dont get sent or I get server errors like:
[BlazeDS]Endpoint with id 'my-streaming-amf' cannot service the streaming request as either the supplied FlexClient id 'B07F3285-A408-816E-4697-F13F9B17E32C is not valid, or the FlexClient with that id is not valid.
Also sometimes when I change subtopics it will cause the FlexSession and FlexClient to be destroyed instead of just the MessageClient. Once that FlexSession gets destroyed it messes up all kinds of things including logging out the user.
Perhaps I'm over complicating things by changing subtopics to listen to different sets of live data, if anyone has any other ideas on how to accomplish dynamic changing of destinations or subtopics please list those as well.

When I pass a Actionscript Value Object that contains a Date variable using BlazeDS it is not getting transferring as a java.util.Date object correctly. When the setBaseDatefunction gets called on the Java side the baseDate value is NULL. The weird thing is if I rename the variable on the Java side to private Date date; and create a public void setDate( Date date) function it works. The problem is I need to pass 2 different dates so I can't uses this work around.
Here are my 2 classes:
AS3
package com.shua.flex.valueobjects {
[Bindable]
[RemoteClass(alias='com.shua.valueObjects.myVO')]
public class myVO {
public var label:String;
public var endDate:Date;

What'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.

We have a Flex-BlazeDS-Spring-JMS application. The issue is sometimes we get a Blazeds error: NoSuchMethodException. It is not able to find the Java service. The weird issue with this it does not happen all the item...1 time it goes through and returns the result, the 2nd time it fails, 3rd time fails and so on. Also not all methods fail, only 2 method calls fail.

My team are putting together a proof-of-concept Flex application sitting on top of a Spring-based server using BlazeDS.We do quite a lot of date calculations, so we use Joda Time extensively throughout the code and in our domain model.We're now trying to figure out how we can continue to use Joda Time in our DTOs that are sent back-and-forth with the Flex frontend via BlazeDS.
Our goal is to use the Actionscript 3 data type Date on the Flex side and have that map to our use of Joda time's DateTime, LocalDate and LocalTime types on the Java side.We can solve the problem of converting Actionscript 3's Date type when calling Java with a custom type marshaller plugged into BlazeDS, but this appears to only be invoked for the Flex->Java/BlazeDS direction and not for the Java/BlazeDS->Flex direction.
I'm now looking at custom PropertyProxy implementations for BlazeDS, but this doesn't look like the right thing either.The other idea was to implement Externalizable on our Java DTOs, but this seems like too much work, especially when I look at the BlazeDS rival GraniteDS and that shows plugging in Joda Time support in their documentation with a simple type converter!

I've noticed BlazeDS has certain things it does not support and it is often difficult to find this out. Ex: polymorphism is not.One must create methods with different names as methods with the same name with different parameters create a conflict.I'm trying to find out if BlazeDS does not support Java static and non-static inner classes.
public class UserDTO {
private String name;
private AddressDTO adddress;
private PhoneDTO phone;
[code]...
The example code above will compile and the getUser method will work. A call to the updateUser or updatePhone methods on the other hand results in a BlazeDS error. Is there a special way to use inner classes in Flex or are inner classes not supported?
Here is an example of the error messages produced:
[BlazeDS]Cannot create class of type 'com.test.dto.UserDTO.PhoneDTO'.
flex.messaging.MessageException: Cannot create class of type 'com.test.dto.UserDTO.PhoneDTO'. Type 'com.test.dto.UserDTO.PhoneDTO' not found.
Example Flex code:
var thisPhone:PhoneDTO = new PhoneDTO();
thisPhone.phoneNumber = "8885551212";
updateTagsResult.token = userService.updatePhone(thisPhone);

I've been trying to find the right configuration for supporting both http/s requests in a Flex app. I've read all the docs and they allude to doing something like the following:
<default-channels>
<channel ref="my-secure-amf">
<serialization>[code]..........
I'm running with Tomcat 5.5.17 and Java 5.The BlazeDS docs say this is the best practice. Is there a better way? With this config, there seems to be 2-3 retries associated with each channel defined in the default-channels element so it always takes ~20s before the my-amf channel connects via a http request. Is there a way to override the 2-3 retries to say, 1 retry for each channel?

I am developing a IT Monitoring Dashboard for the company I work at. The system will primarily perform monitoring of files, databases and servers. There will be a small part of the system which will allow the users to configure static data about the system eg: file locations, server names etc...
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.

I have Flex/AIR app that connects to a tomcat server via BlazeDS. I'm not finding that I have to integrate an old webapp (struts/jsp) and I'd like to keep that webapp untouched except for login, authentication and session handling. Also a 3rd java app that uses httpclient.
Currently I have some blazeDS remote objects to handle login/logout with a few RPC calls. In turn, FlexSession objects are created and handled. Is there a way to use httpclient and javascript to call those blazeds RPCs so I dont have to recode and have 3 different means to handle logins and sessions?

I have my flex object embedded to JSP page.The JSP page retrieves user information like user name and group from portal profile object and stores in http session parameters. The flex Object makes a remote call to Employee.class to perform persona based operation.
I retrieved the session id in JSP and also in the Employee.class both are same. But I am not able to retrieve the username stored in the http session from FlexSession. I read in the internet that the FelxSession will hold all httpSession information as well. It's always coming as null. Correct me if I am wrong.

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.).

Am facing issue with session timeout. Say for instance, the user logs into the application and he waits for 30 mins (session timeout time) and then tries to get a service through remote object.Ideally speaking, since the session has timeout the user shouldn't be able to hit the remote object, but this is happening the other way round.

In a custom MessageAdapter written for a BlazeDS Java server, is there any way to access HTTPSession and HTTPRequest in a custom MessageAdapter.I'm trying to adapt an existing COMET JSON long-poll messaging system to BlazeDS and we use HTTPRequest parameters to specify message sending/polling paramers (such as a unique ContextID for any given page for a user). Is there any type of HTTPSession information we can retrieve in MessageAdapter receiveMessage()?
If I can't access the HTTPRequest (I'm not sure we can even customize it if we're using the standard Producer, Consumer Actionscript classes anyways), is there a way to uniquely identify a given FlexClient long-poll from another long-poll from that client (e.g. if the same HTTPSession user has a tab open to the same Flex application is there any way to uniquely identify that user?).
