Java :: Keep String Constants In Sync Between Flex?
Aug 9, 2010
Say you have a web application that has a lot of business rules built around if-then comparison of String constants. These are used on both client-side and backend code, and at the moment are hard-coded badly throughout both places with lots of duplication and sometimes errors. What's a sensible way to refactor them out? Unfortunately, in most cases they must exist as using polymorphism would be much more hideous. Anything specific for flex/java? Is there an easy way to keep all those constants in one place and compile it into both client and server code?
Edit: I'm really looking for a way to share string constants between flex and java with compile-time checking of everything.
I have two Cairngorm MVC Flex applications (a full version and lite version of the same app) that share many Classes. I have put these Classes into a Flex Library Project that compiles as an SWC. Both applications use some static String constants. Right now, I am storing these in the ModelLocator:
package model { [Bindable] public class ModelLocator
How can I have a constant in a Flex application which I could apply at several places in a Flex CSS file? For example I may have a background color which is the same in several UI components and then I would like to have this color set in only one place and reused in all style clauses. Something like ...
I am trying to set some public static constants on a class conditionally by passing variables to the compiler e.g. -define=CONFIG::ENVIRONMENT,'testing_server'
[Code]...
Obviously this means I have to tinker with long command line setting each time. I thought my initial approach was possible given the documentation and various tutorials I have read.
I have a class ErrorMessages which holds all my error messages as static constants. So I could access them like ErrorMessages.PASSWORD_INVALID or ErrorMessage.PASSWORD_TOO_SHORT. I want to know if it is possible to have separate classes that hold subset of these constants and access them like ErrorMessages.PASSWORD.INVALID or ErrorMessages.PASSWORD.TOO_SHORT, etc. This way I can more structured static structure and makes it much easier to use autocomplete. I tried few different ways and couldn't figure out if this was possible..
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.
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.
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.
Again pulling my hair out due to some Flex/AS3 weirdness. The following code does not compile due to error 1120 - Access of undefined property AbstractWizardModel
I am newer with flex technology.I am creating a chart using ant file & .mxml in eclipse my 'ant' file executes properly but it gives following error when i opens a .swf file which is created auomatically:
Flex Error #1002: Flash Player 9.0.115 and above is required to support signed RSLs. Problem occurred when trying to load the RSL
I'm coding a web app in flex blazeds and Java. I installed the Eclipse plugins for using WTP mixed project. I'm using flex's server that uses an emulate of tomcat when i ran my flex service the web app got the datas, everythings is ok. the problem is when i copy the project with all files generated by flex in my tomcat or the blazeds's tomcat, it doesn't work, this is becasue i want to implement my app on a server the error is:[code] 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.
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() ?
So I'm making my own networking protocol for a online game, to save space each message (sent over TCP) is given a ID which is a short, 2 bytes, all messages sent from the server to the client and vice versa are strings, how can I convert a short to a string in java in just 2 bytes (characters)? I want to be able to convert a short int into 2 characters, so that I can send the short over the network in a string format in just 2 bytes and decode it back into a short on the other side (in actionscript 3). A character can hold 256 possible values right? So 256*256=65,536 which is the size of a unsigned short int!
Here's what I've got so far: public static String toCode(int c){ if(c <= 255 ){ return Character.toString((char)c); }else{ return null; }} public static int fromCode(String c){ return ((int)c.charAt(0));//Return the character code of the send string, 1 char only }
This can turn a int into a single character which can be sent over the network, now I just need to have it use 2 characters and it can do up to a short.
I want tp encrypt and decrypt string, with defined salt. But the result must be same if the code run in java and adobe flex.The main goal is: the app in adobe flex will be generate a string that can be decrypt in server using java.Try to 'Secret Key' Tab. I want to use AES Encryption, 'CBC' or 'PKCS5'.
var k:String = "1234567890123456"; var kdata:ByteArray = Hex.toArray(k); var txt:String = "hello"; var data:ByteArray = Hex.toArray(Hex.fromString(txt));;
There are many dynamic languages that target Sun's JVM (Groovy, Scala, Jython, Jruby etc) and I was sure there are many that target Adobe's AVM as well. But I was surprised to find only haXe do something similiar. related question on this site
I think the eclipse e4 SWT project doesn't compile to ABC (ActionScript Byte Code) directly, but first converts Java to AS3 and then the Flex compilter does the rest.Could it be that no one yet wrote a simple Java / Python / Scala AVM2 compiler that can be used as an alternative to the proprietary Adobe Flash Builder (formerly Flex Builder)?I don't mind paying Adobe for a fine producy, but writing Java in eclipse is so much faster and convinent than the half baked adobe plugin suite. are there really no efforts other than haXe?
I have an image file, in *.tif format, that looks like this: As you can see it contains an image along with a lot of text. Is there any way to read my .tif image and extract the text content into a String ?
Since I'm developing a multiplayer card game for Facebook using Flex as client side and Java SE as server side, I wanted to know how do I actually make the connection between Flex and Java? the server and client should be able to send each other data(cards,movement,room information etc...) across and I wonder what's the easiest way to do it without complicating it. where to read about it ? I know JAVA but I find JavaEE hard to understand.
I have a String variable in my flex (flash builder 4) application containing CSV data. I need to allow the user to download this data to a local file. For example, giving them a "csv" button to click and it might present them with a save file dialog (and I would be sending the contents of my string variable).Is this possible / how ?I am using the ResuableFX component for the datagrid to csv. This the code I ended up with that works to save the string to a text file for the user (in a web browser):
var dg2CSV:DataGrid2CSV = new DataGrid2CSV(); dg2CSV.includeHeader=true; dg2CSV.target=adgEncounters;
I am writing a game where positions of an object are being exchanged between the two flash clients through a java server. The secnario goes simply like this:
PlayerA ---> Server : "Position X + Position Y+ " Server ---> PlayerB: "Position X + Position Y+ "
and it works both ways of course.the problem here is that on my computer where i use "localhost" everything is fine and the data is exchanged seamlessly .. when I loaded the server on a remote host the message received strangely turns into something like "Position X + NaN" (i.e. the y position is wrongly parsed by the server), what is weird even more, is that sometimes, the message gets parsed correctly..the server is wrote in java and it is exactly the same source code that works on my machine that fails over the internet
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 have implemented application client-server with spring blazeDs message services using JMS message destination. The idea is a producer declared in Java send message using activeMQ and consumer declared in Flex receives them. I have configured the AMFChannel with a polling interval 0, but I have seen when the consumer subscribes to the destination in Flex, the time request can be of up to 3 seconds.
