Java :: Use A Wrapper Class Around An Object In Flex?
Jul 11, 2009
Select a school listed in the first datagrid, and display all the student records /details of that school in the next datagrid. But, since datagrid is editable and requirement mentions : "Use a Wrapper class around the object to get the data, set the same and save. Ensure wrapper is bindable to take into consideration the updates being made to datagrid text fields."
I have an object which is a type of a Data Access Objects i.e. DO.
mySchool:mySchoolDO.
The mySchoolDO is an actionScript class of following code :
public class mySchoolDO
{
public var schoolName:String;
public var schoolLocation:String;
[code]....
The showSchoolStudents will display all the details of students on to the datagrid. But, my datagrid is editable. And, I want to use WRAPPER CLASS around this object such that
a> I can retrieve individual values as present in studentsDO i.e. studentID, studentCourses, studentGender, studentPhone.
b> I shouldbe able to set the values as they are updated in the visual datagrid.
c> Finally save all the data and submit on submit click.
I'm still learning how to compile with the Flex SDK. And I'm learning how to use SWC files and [EMBED] statements to pull my assets into my application.With the Flash IDE, I can link a library asset to a class and it's automatically embedded into my custom class. So that's 1 asset in 1 class. With the Flex SDK and SWC files, it seems I can only* pull in assets at the variable level, so I end up with my custom classes containing yet another class -- this means I have an extra wrapper/decorator (whatever you want to call it) class that I didn't have when using the Flash IDE.Is this what people typically do? Doesn't that seem superfluous?I've read Colin Moock's 'Essential Actionscript 3.0', where he mentions something about embedding a SWF at class-level as binary data.
I tried with flex and java in the backend. In this, I am able to upload files till 100 MB using remote object (blazeDs) where we will read the file as byte array and send it to the java method. If the file size exceeds after that, then I get the run time error in IE.
Assume I have the following java class public class Square {
[Code]...
Inside an actionscript class, using RemoteObject, I invoke the java method SquareDAO.findById(Long id) an I get an Object with the following: But I don't get the area. How can I invoke the method getArea() ?
I have a RemoteObject returning a 'Schedule' class. I've created a client side RemoteClass to map to it. All properties of the class instance are coming in fine. I just not clear on how I go about calling methods on the class. How would I call a setter on startdate?
package classes.remote { [Bindable] [RemoteClass(alias="com.site.data.schedule.Schedule")] public class Schedule { public var id:int; public var modifydate:Date; public var startdate:Date; public var enddate:Date; }}
From java i am sending ordered Map.In flex when i convert that into Object i am loosing the order which i maintained in java.Is there any other way to maintain the order in flex object?
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'm building an application using Flex 4 + Spring Blazeds Integration 1.5 + Spring 3.0.5 + Hibernate running on jboss-5.1.0.GA. I create a simple login form, and when a submit a string via remote object it works fine. But when a try to use an Object its simple doesn't work. Funny is that it even don't shows the Alert that a put! Also, if I remove the tag "RemoteClass" it sends to java but an error occur. Bellow is the code and configs.
We have a pretty big application with lots of objects being passed between flex and java One object in particular has a subtle bug:It's a plain old java object being passed to the flex front end (using blazeds producer/consumer messaging). The POJO has two String properties such as:[codewhen I get the object on the frontend, in Flex, the value object's properties are swapped, as in:[code]Clearly, this is some type of confusion blazeds is having when the objects are serialized/deserialized. Since they are both Strings, it seems something is getting confused when reading/writing the objects.Both objects exactly mirror each other with parameters and methods in the same order in the files with the same names.How do I correct the serialization, preferably without having to handle it on my own?
the problem is as so: I have a java server running on tomcat 7.0 and having the library Gson 2.1 on it. I have and object to be encoded into json that got an attribute which is an array and might be an empty one.
when I send my json object via the response writer to the Flex Builder 4.5 in the Network Monitor view in the response type I get unknown. well, I have done my research, and discover that this is a known issue.[URL]..
adobe said that with Flex Builder 4.5 this issue will be fixed. but apparently it ain't so.
When I make changes to a Flex project and rerun the project, it seems that FlashBuilder4 rewrites my html wrapper that embeds the SWF. But I have additional javascript code in the html wrapper and don't want to keep losing my code. I had to re-write the code once and it was a pain in the neck.How do I stop it from re-writing the html. And the related question: how do I stop it from deleting the html during a clean?I basically need to exclude the html from its processing once it's been created the first time. P.S. I'm using Flash Builder 4, but I suppose it's the same in Flex Builder 3.
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 have a custom java class which has an ArrayList and corresponding to it have a custom vo class which has ArrayCollection (in Flex).I want to return data from Java to flex.Every variable in java is getting mapped to vo perfectly except for ArrayList.When trying to retrive When trying to retrive exposureUSDList (which is an arrayList) in flex I am getting empty ArrayCollection. It is not getting mapped properlyPlease find my code below:
I have an ArrayCollection containing bindable objects. I would like to access them in multiple places like below (there's only one label for clarity). How can I achieve that?hould I write some kind of wrapper for ArrayCollection dispatching special event (which?) catchable by Flex event mechanism.
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 instance
I am developing with Flex + java + hibernate in one project. I am trying to add one more advanceddatagridcolumn in flex AdavanedDataGrid control. Actually it work very well but only except I added columns data. I have no idea what should I do to make it out I am telling work flow. At first call select method in DeliveryService.class through the RemoteObject and then call DeliveryMgr.class for call business work. After get return list type return value it pass to presentation class to setting all of the selected return value. I can print trace log what I added columns data in DeliveryPt.class but it cannot return to flex area.Strange thing is I can check out value of what I want to show data in DeliveryPt.class but it does not show up in AdvanedDataGridColumn of Flex.
In Flex builder 3 when I create a new flex application targeting the flex 4 sdk, it wont generate a html wrapper file. I have hunted around the web for answers, but no success. I have made sure the box is checked in the project properties to generate html wrapper.
The only workaround is to target an older version of the sdk (i.e. 3.2), which will cause the wrapper to be generated. Then I can revert the project to sdk 4. This then means I can never do a clean of my project because this will result in the wrapper being deleted. Has anyone else come across this? Is this just a bug with Flexbuilder3?
I've been trying to do as the client requested : redirect to campaign page then to destination page once a customer clicks on the top banner in swf format.If you are using Firefox, Chrome or Safari, I suspect you can reach the destination page.However, if you are using IE or Opera, I doubt it.I think to cause of such a weird problem is:The swf ojbects don't have a link to url, SO I have to hack the theme template file like this :
<div id="header">'; /* * A quick and dirty way to put some swf into PHP, and rotate among them ...
I have a java class which has been deployed as WAR web application in a BlazeDS/Spring server sitting on JBOSS. Apart from the Flex application which will access the WAR file, I also need to start some server side process's which will initiate BlazeDS "pushes" to the Flex client via AMF messaging.
What is the best way to implement this server side process? - Should it just be a class with a main() method in the WAR file which gets called from the command line? Can this be done - not sure you can run a class in a WAR file from command line? - Should it just be a class with a main() method in a JAR file which gets called from the command line? Not sure what the standard practise here is. The key is that the process needs to be started on the BlazeDS server to push data out (not on the Flex client).
I seem to be getting the following error when I try to access a Remote Java class (on Spring/BlazeDS) from the Flex/Cairngorm application. I am going crazy at the moment trying to see what is wrong
I'm building an Flex 4 application using IntelliJ IDEA 9.0.2 generated sample Flex application. I replace the generated mxml with the following code from the book Hello Flex 4. It simply crashes the browser when I run it. It says "Waiting for [URL]..and then crashes I tried it on both FF 3.5.9 and Chrome 4.
I could play MIDI file where "filename" is a String type with "asd.mid" value. However, I tried to sent AIR's nativeprocess command to Java, it shown "could not read" error.
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);
I'm building a Facebook multiplayer game where the client side is in FLEX and the server side is in Java and I wanted to know if there is a guide on how to build the server clients managing system. When I say server clients managing system, I mean a server which many clients will connect to and will be able to choose between tables to join and play or to create their own table, same way as in texas holdem poker.
i am working on a flex+java combined project.My IDE and computer configuration is as follows:
[Code]...
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.
