Mysql :: Flex - BlazeDS - Hibernate (Tomcat) And Air Cannot Reach The Database Server
Oct 11, 2010
I create a Flex application that works with a browser using a database with the MySQL server that I can create, modify and delete data from a database. The problem I encounter now is that I want to see my program with Adobe AIR (virtual machine). At the display that does not pose a problem. The problem is that air can not reach the database server is located in the MySQ. the error message displayed is as follows: "Error : client.Error.MessageSend - Channel.connect.failed error tConnection.Call.Failled : HTTP: Status 404:url:'[URL]"

I have a typical Flex-based application that was written to use a Java/Hibernate/MySQL backend. The client changed the requirements - now they want to distribute it on a CD where the user can just run the app without any installation or a network connection.
To do this, I certainly need to eliminate the web server and the database server and adapt my application (with as few changes as possible, of course) to a stand-alone application that will fit on a CD/DVD. I've managed to export the data to XML and read it into Flex, but I'm wondering if there's a way to recreate the Hibernate data structures in Flex so I could change as little code as possible. Failing that, is there any way to keep the existing Java/Hibernate external to the Flex code but retrievable without installing Apache Tomcat or MySQL?

I've followed the getting started for BlazeDS. I'm making changes to the Flex code using Flex Builder 3, but I just can't get the changes to show up when I refresh the page on my client. Server and client are separate physical machines, I've even re-started the server hardware. One curious thing, even when I re-started the server I didn't have to re-login to the Tomcat manager page

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'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.

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.

I've set up a small project as a test. I'm using BlazeDS and JPA with Hibernate on my test server, and flex with with dpHibernate to access the Java entities. Each Java entity extends BaseEntity, a class that contains ID and UUID fields. The Flex entities are created by DTO2FX.
when I run the Flex project to try and display a few rows from a Users entity, the SQL that is actually being executed is joining every table in my database. This continues until I get java.lang.StackOverflowError. This behavior is completely unexpected, and I'm not really sure where to look to fix the problem.
@Entity
@FXClass(ignoreSuperclasses={Principal.class, UserDetails.class})
@Table(name="edrUser")

One of my web applications have developed in java and using tomcat server. Now I want add one more feature in my application that is peer to peer audio streaming. Actually I want that anyone speak (using microphone) on the client side and I will hear his voice on my server speakers and vice versa. Also save our communication in any file and also send the audio stream to IP intercom.
For that I am trying to use Flex Builder. Flex NetStream class is good for the streaming and we can also attached microphone. But the problem is on the server side. How can I get the audio stream on server side?
how can I get stream from server to client and vice versa?

So I want to store richtext in my database created from Flex 3's rich text editor, but I am unable to.
for example this would need to be placed into the database:
<TEXTFORMAT LEADING="2"><P ALIGN="LEFT"><FONT FACE="Verdana" SIZE="10" COLOR="#0B333C" LETTERSPACING="0" KERNING="0">sdfsdfdsfsdfdsf</FONT></P></TEXTFORMAT>
Is it because of all the special characters?
Is it common practice to store formatted text in a database?

I want to create a Flex 3 application running in Adobe Air that accesses an SQLite database and I need to keep this database in sync with an SQL server 2005 database running a website.Is this something that Flex supports or is it going to be a custom script? Also, has anybody done anything like this?
Edit: The synchronisation can be done on a daily basis rather than real time. The data will be read only from a front end perspective with a CMS to do updates on the website.

I'm making a program in flash builder 4.5 using WebOrb 4 (which is fantastic, I might add). When I go to deploy, however, it gives me this error:

>The server returned the following message:

>Unable to contact the RDS Server "Data Services on Tomcat (localhost)."

I've poked around online for a solution, but for the most part I either don't understand them (forum grammar can be somewhat obtuse) or the answer in the post doesn't apply.

As far as In understand the Flex technology, a Flex client connects to a Flex server to retrieve business information. Is this the only allowed connection for the client, back to the originating server? Or can a Flex client also open a secondary connection to a different server wich runs BlazeDS for message exchange?(This might offer an option for load balancing and cross-platform development).
Update: I have found this page which links to the Cross-domain policy file specification:[URL]..

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 a question about the Java Factory; I've read somewhere that: "... the JavaFactory will check if there is already an instance in the scope and return that. If the object is not available then it is instantiated ...", but I don't understand the expression "if the object is not available"?I am having trouble to find and/or assign classes already instantiated (by another class) in the server, to a declared destination.
I'm developing an application in Java: J2EE.I'm running it on a Tomcat 6 server I'm using BlazeDS to communicate with Flex. I'm using the RPC's Remoting Service (through RemoteObjects)There are two java classes that handle Client (Flex) interaction, say ApplicationClass and UserApplicationClass:
ApplicationClass has a reference
(attribute) to a UserApplicationClass

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?

I'm currently working on a project that need to communicate with java from air without the use of a server like Tomcat. For this i found and use Flerry.Communicating between Java and Air is no problem, as long as I try to send a message from the class that I initially instantiated from Air.What I try to do is subscript to messages from a Message Class in java and use that class to send info and errors to Air from Java.
MessageController.java:
public class MessageController
{[code]....
the infoMessageHandler receives an message containing test message, as it should. How can I dispatch messages from whatever class in Java and catch them on the Air side?
