Java - Organization Of Services In Service Layer?
Oct 11, 2011
I have a Java server application with a ton of different entities. So far, each entity top level entity has its own CRUD service. By top level, I mean the root of a tree of entities that can stand alone.
Now I am getting into the heart of my Flex client and find I am needing/writing many different queries. But where best to put these queries?
Say for example, I have a query to find all "foos" based on their associate with a certain "bar". Currently that query is on the "foo" service (findAllByBar), but I am finding that it would be very convenient to have it (also?) in the "bar" service (findFoos). On the other hand, I could also create a query service and lump all the queries in there.

I have a Java-based server side and a flex client side using Spring BlazeDS Integration. It works fine, but I want to get sound from server side recently. I followed this BlazeDS mapping doc, it says when Java return a Byte[], it will be converted to ByteArray which I want. So I handle the MP3 file by ByteArrayOutputStream, convert it to Byte[] and return it back to front-end, but the value that Actionscript gets turns to be null value.

I'd like to learn how to create a java web service that can be consumed by a web tier, which is constituted of java and flex. What books can help me learn how to create a java web service and consume it via java & flex?Should I look to build a web service from scratch or from frameworks like: XFire, Axis, CXF, Spring Web Services, etc.?If using a framework is recommended, which of the above or any others makes the most sense to learn/use?
EDIT:Both the java AND flex components of the web tier need to independently access the web service. For example, the flex component helps the user create & save a spreadsheet; the java component retrieves the spreadsheet data and displays it accordingly.

We are planning to use flex and Java Web Services, what is the best practice to consume web service from flex is it better to directly call the web service from Action scripts or to use remoting where java client will call the web services and later flex using remoting will the java client?

We have developed a web application. (Eclipse - Dynamic Web Project). We are deploying it as .war file. We want to implement evaluation period license check on this .war file. (Most of the functionalities are Java SOAP Web services and Web UI is in Flex). I have written a Java code for generating the license file and thread for checking the remaining days. (Checking is continuous as the application is supposed to run for days). What is the best way to implement this functionality on the web application using the generated license file?

I have a Spring MVC web application which provides RESTful web services via a controller class (annotated with @Controller) which has methods mapped to specific request types and signatures via @RequestMapping annotations.I have attempted to integrate a BlazeDS service destination into the mix by 1) adding the HttpFlexSession listener to the web.xml, 2) adding the flex:message-broker and flex:remoting-destination declarations to my Spring application context configuration file, and 3) adding a generic /WEB-INF/flex/services-config.xml.
The above BlazeDS integration steps appear to have hosed my RESTful web services, in that it appears that requests are no longer being routed to the controller methods. Is it even possible to do this, i.e, to have a single web application which 1) services HTTP requests via request mapped controller methods and 2) services remote object method calls (i.e. from a Flex client) via a BlazeDS service? If so then can anyone tell me what it may be that I'm doing wrong?

I am new to Flex and need to integrate Java services with Flex UI built using Mate framework. Can anyone point me to any website/links or show an simple example of integrating Flex UI on Mate framework with Java remote services? A simple integration of a "LoginService" will be good enough.

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.

Has anyone used or is aware of a service browser to test AMF calls?I am looking for a tool similar to ZamfBrowser ( http:[url].... ), but one that works for the Java environment.ZamfBrowser is geared towards AMFPHP.The idea here is to provide a service browser, that allows developers to test Java services using the AMF protocol, without having to go through the Flex UI all the time. There has got to be something out there already for this, but I can't seem to locate anything..... It's kind of funny and strange that a service browser exists for AMFPHP but not for regular AMF calls in a Java environment.
I would imagine something exists under Blaze or LCDS? ...Trying to find it in the docs but can't seem to find anything ....The best alternative I can think of at the moment is to use FlexMonkey to record stuff, and then to simulate it using that....which is okay I guess but still sucks because you have to go in and create the Flex UI first, whereas with something like ZamfBrowser, you simply point it at the service calls,it tells the server-side developers if their code works, etc. generates the required as3 classes for you... and makes the integration process much easier in a large team.

I created a Java REST service using Jersey. I use three of the HTTP "verbs" GET, POST and DELETE. I want to create several prototype front ends for the service. After much research, a lot dating to 2008 and 2009, I have been unable to find anything remotely simple.My three options are:
1) resthttpservice. This project hasn't been updated in a year. The only activity are one off suggestions that individual users have implemented.URL...
2) Create an AIR application. This isn't unfeasible.
3) Writing my own socket level code but there is a security restriction with flash players and I need to implement a policy server.
I have already read the question posted about asking whether using Flex for REST services were worth it. That information is old as well. I want to introduce REST services to my company but Flex's limited support for HTTP PUT and DELETE are discouraging. My service also uses the Accept header to determine if JSON or XML will be returned to the client. I can't seem to change HTTP headers without doing socket programming.Is there an easy way to use Flex 4 with RESTful services that uses PUT/DELETE and the Accept HTTP header?

I have been working on a flex application with java, as i have used Life Cycle Data Service for communication, i wana know, is there any function of flex, where i can see the loading status in percentage, that how much record is being loaded.Problem is, if there is lengthy record, no body comes to know, whats happening with software, like in Comboboxes or Grids, users usually think it as a BUG in application, but ofcourse it is not.I need such graphical loader, which keeps on loading with proper status in percentage, until it receives all data from JAVA (SQL Server).

I am developing a flex application with flex 4.1 sdk and java backend (runs on Glassfish 3.1 via http). For security reasons I decided to move my authentication process to https until a session id is obtained. Therefore I changed the filter settings to use ssl for login and logout pages(just two pages due to performance reasons. The data-size sent to client is large and I do not want to slow down the system). Glassfish forwarded these pages to 8181 port (which is HTTPS port). Everything is ok for the java part. However flex defines the 8181 port as a different domain and then problems arise. Due to flash's same-origin policy it cannot load the secured content. Normally a crossdomain.xml is the solution but I am accessing content of the same domain through a different port. What will be the solution ?

I am looking for a model to organize my ui classes so that more than one class can apply to the same displayObject. Consider this example:
I have a AlphaButton Class extending from MovieClip that changes the alpha state on MOUSE_OVER and MOUSE_OUT.
I have a ScrollButton Class extending from MovieClip that holds actions to scroll a scrollbar.
I want to keep these 2 classes separate so that they may be reusable in other projects. But right now, I want a ScrollButton that has the AlphaButton interactivity.

I am creating a side scrolling game in Flash (as3) and trying to keep things organized and clean.Ive created a "Level" class that gets all the level data, player data, and creates all the terrain objects and the player object. Its starting to get messy because im handlng all of the functions for player collision checks and player movement, terrain movement, sound starting and stopping, enemies, and more, all in this class. Is this normal? Or is there a better way to organize things to keep them separate, but still allow them to interact with each other.

I've decided to finally make my own full flash site. I've got more than enough Flash and ActionScript (and XML) knowledge to pull it off nicely, but I was wondering if people who have already done this have any advice for me in terms of organizing the whole thing, so it's easy to upgrade and follow through during the time you build it. I was thinking a standard layout, maybe an intro and a first preloader, then a menu that choses sub-sections and each has an intro and outro transition? Oh, and for seperate sub-sections, do you put the preloaders in the main movie or do you include the preloaders seperately in each of the subsection swfs?

I am experiencing a strange problem when I want to bind a service to a button or something else:
[Code]...
I can add the services to the Data Services panel but I have two strange things:
1) when I want to configure the return type he doesn't let me create a new ValueObject type, I only get the bottom datagrid which states: Properties returned by the operation: Property: country_Id, provence_Id, city_Id, id_cdpc, district_Id with the related values on the right side. Why can't I create a new data type on the top?
2) When I accept this and want to add the service call to a button (drag&drop) I get the following error: Error occurred while generating code. Make sure that there are no compiler eroors and try again after reopening the file. Componentn type services.cdpc.CDPC not found... (ps: When I perform a Test Operation everything seems to be ok, I get the expected output values)

I am doing some research on creating clcikTags. I read a few places that the clcikTag should be on the top layer. That has been fine, but now I want to loop it and I usually put my actions in the top layer. Will this cause a problem? Am I better off just putting my loop action on the last key frame of the clcikTag layer?

Im creating a program that is designed to allow the used to select 3 pictures (movie clips) and print them off on a single peace of paper.
The program works by allowing the user to select 3 graphics (the graphics are actually instructions for various exercises) and then moving the desired movieclips onto the stage. This all happens on a layer named "Content"
So far the program will allow the user to select the movieclips and will move them into place on the Content layer as well as move smaller versions of the pictures into a preview box the only thing it does not do is print. (the most important bit)
