With flash and SQLite being supported on the new tablets and smartphones.Is there a database abstraction layer similar to hibernate for java but written in ActionScript3 that supports SQLite?I would rather concentrate on the User Interface rather than the data services portions of the applications.
View 1 RepliesI'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")

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]"
View 2 RepliesI have a situation where i have relations like this:A person has one or more addresses.A customer has one or more addresses.Person,customers and addresses are separate tables.I used to do this with the @OneToMany relations.This is giving me problems since our flex client is sending me objects wich are created in the client ad have to be created in the DB.If the client sends me a person and customer which reference to the same address hibernate will create two address objects since the two address object are not the same java objects (not the same pointers).This is a problem which is caused by BlazeDS and Dozer which will create new objects when they are send to the server.So what i would like to have is the address id in the person and customer object without an relation so hibernate does not create the objects. But when i read a person object i would like to fill a transient address object based on the stored address id.
View 1 RepliesI try to start JEE, so after studying the frameworks avalaible for this architecture, i choose to use the following one: Flex, BlazeDS, Spring, Hibernate, mysql. i will work with eclipse or STS.The problem is that, after trying different project all over web tutorial, i wasn't able to create an architecture that gather all the last versions off technologies i choose.SO, can someone send me a links which refer a tutorial where it's preferable that the source code is available to download, and it gives the explanation about what is done.
View 2 RepliesI'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--
package flex;

Is there a good Maven archtype for Flex Spring Hibernate integration which can be used as template?
View 1 RepliesI need to be able to tell when the os has came back from sleep/hibernate/standby.Problem I'm having is that I have a timer that needs to fire at certain time. The delay is calculated so that it will fire on certain hour:min:sec. Problem is when the os goes to sleep, the timer is "paused," which caused the timer to fire on wrong time. I would like to be able to update the timer delay when the os comes back from sleep but there doesn't seem to be a way to do this...
View 1 RepliesI 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.

Is there a commonly used framework for AIR that handles mapping objects to and from the built-in SQLite database? An Annotation-based ORM framework that is to AIR what Hibernate is to Java? Background We have an AIR application that runs offline. I need to save/restore complex objects to/from the SQLite database. Some of these ValueObjects contain references to other ValueObjects. For example, an Order object contains a Customer object which contains an Address object.
Ultimately, I'd like to add metadata to my objects, like an [Entity] tag and have persistence "just work," with minimal configuration. I could roll my own ORM solution, effectively writing "Hibernate for AIR" myself, but SURELY someone has already done this. I've read related posts like Best practices for developing AIR Application with SQLite that advocate creating DAO's, Builders and Services. That's a fine solution but, of course, no one wants to reinvent the wheel if it's not 100% necessary.

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.
I am preparing a document for a project. The project's backend is developed in Java, frontend is adobe flex.
I am not sure about the correct way of describe the project in Model-View-Controller way.
For Model layer: Using Hibernate Java beans to implement all the business logic and persistence? For View Layer: Using Adobe flex send post or get request to Controller layer, and get respond in XML format. For Controller Layer: Using Java servlet to handle requests from Flex client?
i want to intertwine php, MySql and flash. so i can make a flash movie display text that is in the sql database and a php script to change the database, php > sql = i can do but sql > flash = i can't do..i want it so the sql data show's in a text box in the flash movie...
View 1 RepliesI 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 have researched this issue all over and most people say use the .refresh() method to update a datagrid after updating or adding a new record. This does not do anything. So, my issue is this. I have a mySQL database hosted I am connecting via PHP, I have 1 mxml file and 2 php files (I know I can use just 1 but I am learning and this was easier for me to use for troubleshooting). The issue is no matter what I change on the datagrid the update does not show on the datagrid unless I close out of IE and reopen it. I can refresh or open the page in another window and the update does not show. I have to exit entirely and restart in order for any updates or additions to show.Here is my licenseTracker.mxml

I am working on a function to generate a form at runtime in Flex based on a call to the DB. The call to the DB returns the field types, id, tooltips etc as an arraycollection, the arraycollection is then parsed in order to ascertain what control to display based on the type field in the array - this bit works fine.However, i am stuck on trying to save the form fields back to the database using a CFC.my form rendering code is as follows but how do i save values entered back to the database? rendering code..

I am planning on using Flash Builder 4/Flex to write an AIR application which is primarily based around recording, storing and analyzing data.I'll be creating charts etc that need to update in almost real time.It's essential to me that the application be able to function without an internet connection so I need a local database of some variety,but I would also eventually like to build in online synchronization of the data where either database can be update each other based on newer information. Moreover, some type of encryption would definitely be welcome, and speed is a large concern
Synchronization: Primarily updates/additions/deletions will be done on the offline database, but ideally I want to have a web interface that will allow the same updates/additions/deletions and will be synced (beyond that I'm not sure exactly how to do it as I can model that based on what is most achievable).I'm wondering if there's any prebuilt engine that could handle the synchronization of 2 databases. I may end up having the web interface only be for additions, which would be significantly easier to sync.. and I may start that way, but i want to build with technologies that will best allow me to implement full online crud at some point.

View 3 RepliesHere is the issue: a client wants his entire equipment inventory accessible by persons navigating to his jquery mobile site. The inventory that exists on the desktop site was, as I understood, built with Flex. Is it possible to access this database for the jquery mobile site? I believe it is. I was then given this information from someone in the know:
Database:
mlxx.db.xxxxxxx.hostedresource.com
login: mxxx

Is it possible to create a database driven website using these alone? Or do i need to learn any other technology? If i do then what should i learn? I know j2se for the desktop and oracle SQL/MySQL i finally got the feeling that i need to learn PHP anyway along with css and javascript. So it is fine. Also another query. Which CMS should i consider? Wordpress or Joomla?

Is there a way to do it with action script only or I must do it another way?
View 1 RepliesI 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?

View 1 RepliesI have a rather large Flex SWF and am breaking it up into separate Modules. There is some overlap between the modules and I want to put all of this into one shared RSL. The problem is that this RSL gets really large as soon as I use any Flex code because it has to include the Flex Library.Flex Builder doesn't seem to give me the option to use the Flex framework RSL in a library. Also compiling with compc and passing the runtime-shared-library-path doesn't seem to actually use the rsl.So it seems like this is something that is unsupported? Does anyone have any idea how I can do this? Is it just not possible? Is this something that is likely to be supported in the future or already supported in Gumbo?
