Java :: Java, BlazeDS And Config File For Application?
Nov 11, 2010
I'm programming Rich web applications with Flex and Java on Flex Builder 3 using blazeDS and SharedObjects.Now I need that my program will use configuration file.so, I need that my Java class will read it at the first time but the default path of java to read and write files is c:program filesFlex Builder 3 and not my application directory inside the tomcat webapps directory How can I read the config file from the java class without write the path hardcoded in the java?

i am working on a flex+java combined project.My IDE and computer configuration is as follows:

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.

What's the best way to secure a Flex-BlazeDS application? I've googled it an several solutions came up.UPDATE after question from jsight:Flex would login, so on the RemoteObject I'll set Credentials I don't know if there comes authentication and authorization with BlazeDS (WebORB for instance does and WebORB looked at BlazeDS for their product) SSL not needed 've seen some links on the internet talking about spring security, so I'll check that out.

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.

Is it possible to deploy my Spring/BlazeDS/Java application to elastic beanstalk? I'm using MyEclipse and built a Java Web Project with the required jar files etc. Do you need to specifically create an AWS Java Web Project - reason I ask is the options to include the BlazeDS files aren't there - so I'm wondering if Spring / BlazeDS is even supported? By default the turnkey blazeds runs through Port 8400 - so I imagine there are some additional tasks required to configure the endpoints to work through port 80?

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 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'm using BlazeDS 3 in my application. The dependencies for the BlazeDS libraries are downloaded from a public maven repository. However I can't enable the RDS support on the server because of some missing library. Does anyone know where this class is located: flex.rds.server.servlet.FrontEndServlet.

I have a BlazeDS destination and the scope is set to request. Is there a way to get BlazeDS to call destroy() when the request is complete? Is there another way to know when the request is complete?
I know I can use finalize(), but that is only called when garbage collection occurs.

has anybody tried using a custom classloader with BlazeDS? We have a web application using BlazeDS and we can convert Java objects in to ActionScript object and back without problems in the main application. However, we also have a plug-in mechanism based on a custom classloader.BlazeDS cannot map the types contained in jar files of that custom classloader since I don't know how to tell it to BlazeDS.The livedocs of TypeMarshallingcontext show a setClassloader() method, but since the context seems to be a singleton, I assume this will not work if you have multiple custom classloaders (we have 1 for each plugin that is deployed

I'm starting a flex+blazeds project. First I coded some server classes, and modified xmls (in WEB-INF). Now I want to test it with client. There (in Flash Builder) it's needed to specify path to folder where server lives. The problem is that I cannot find it. In the same time [URL] is found in browser.

I have two applications: a client in flex and a server in Java. When I deploying the application inside flex builder with the tomcat server inside as well, everything works fine. But now I'm trying to deploy in apache tomcat outside the flex/eclipse builder and I have a problem.I think the problem is with relative/absolute paths but I do not know how to resolve it.In my Java application I have to access a database and a get a file from it. I use a properties to set a path where I want to download that files like this:pacs.ruta=C:\resources\And then I need to access to that file so in use this code:fin = new FileInputStream(pacsRuta+""+f.getName());where f.getName() gives me the name of the file so I get the path of the file with the path I set in pacs.ruta and the files name.
I do not know why it does not work. I tried to put pacs.ruta=/resources/to associate with a folder in my application but It does not work.Could someone give me an advice? Do you think it is the problem? Because the whole application works fine deploying in a tomcat server outside the flex/eclipse builder but when this code is called the application does not work.

I using messaging in Flex-BlazeDS. When the AIR client starts it connects to a destination and a specific subtopic. During runtime, the user can use a combo box to subscribe to different sets of live data coming in, this combo box change event changes the subtopic by:
messagingConsumer.subtopic = subtopicComboBox.selectedLabel;
messagingProducer.subtopic = subtopicComboBox.selectedLabel;
messagingConsumer.subscribe();
A message is then sent to the server with the new subtopic name as well so the server knows to send to a new subtopic. This whole mechanism seems very glitchy and I'm wondering if anyone else has tried this and succeeded? Most times it works the first time and the after that either the messages dont get sent or I get server errors like:
[BlazeDS]Endpoint with id 'my-streaming-amf' cannot service the streaming request as either the supplied FlexClient id 'B07F3285-A408-816E-4697-F13F9B17E32C is not valid, or the FlexClient with that id is not valid.
Also sometimes when I change subtopics it will cause the FlexSession and FlexClient to be destroyed instead of just the MessageClient. Once that FlexSession gets destroyed it messes up all kinds of things including logging out the user.
Perhaps I'm over complicating things by changing subtopics to listen to different sets of live data, if anyone has any other ideas on how to accomplish dynamic changing of destinations or subtopics please list those as well.

When I pass a Actionscript Value Object that contains a Date variable using BlazeDS it is not getting transferring as a java.util.Date object correctly. When the setBaseDatefunction gets called on the Java side the baseDate value is NULL. The weird thing is if I rename the variable on the Java side to private Date date; and create a public void setDate( Date date) function it works. The problem is I need to pass 2 different dates so I can't uses this work around.
Here are my 2 classes:
AS3
package com.shua.flex.valueobjects {
[Bindable]
[RemoteClass(alias='com.shua.valueObjects.myVO')]
public class myVO {
public var label:String;
public var endDate:Date;

The weird issue with this it does not happen all the item...1 time it goes through and returns the result, the 2nd time it fails, 3rd time fails and so on. Also not all methods fail, only 2 method calls fail.

My team are putting together a proof-of-concept Flex application sitting on top of a Spring-based server using BlazeDS.We do quite a lot of date calculations, so we use Joda Time extensively throughout the code and in our domain model.We're now trying to figure out how we can continue to use Joda Time in our DTOs that are sent back-and-forth with the Flex frontend via BlazeDS.
Our goal is to use the Actionscript 3 data type Date on the Flex side and have that map to our use of Joda time's DateTime, LocalDate and LocalTime types on the Java side.We can solve the problem of converting Actionscript 3's Date type when calling Java with a custom type marshaller plugged into BlazeDS, but this appears to only be invoked for the Flex->Java/BlazeDS direction and not for the Java/BlazeDS->Flex direction.
I'm now looking at custom PropertyProxy implementations for BlazeDS, but this doesn't look like the right thing either.The other idea was to implement Externalizable on our Java DTOs, but this seems like too much work, especially when I look at the BlazeDS rival GraniteDS and that shows plugging in Joda Time support in their documentation with a simple type converter!

how to structure the comms of a blazeds/flex game. What I'm trying to achieve is to have x no. of games occuring on the server each of which will contain 2 to 6 players. i think this will involve segmenting a feed, by creating a subtopic. eg game A gets filled with Player A + Player B, a dynamic destination gets created on the server side, and the new destination id gets returned to the clients. Not sure if I have that correct - to give some further background - the main server side code for a 2 player setup is here

I have a java class which has one field with getter and setter, and a second pair of getter and setter that access this field in another way:
public class NullAbleId {
private static final int NULL_ID = -1;
private int internalId;
[Code]....
(the reason for this construction is that I want to build a way to hande Nullable Intergers)
On the Flash/Flex client side, I have a Class with two properties: id and internalId (the id properties are only for testing, at the end they should return the internalId value)
BlazeDS seams to transfer both values: id and internalId, because both have a complete getter setter pair. I want Blaze not to transfer id, only internalId should be transferred.

I have 2 java classes that are the same (imagine the getters and setters):
class ScheduledEvent {
private String eventName;
private List<eventValues> values; [code]....
Now there is a reason why there are two classes that are the same.When something is "scheduled", I should get the ScheduleEvent object and when an event is started, I should get the StartEvent object.And depending on the object I get back, I do different things.My problem is that, on the backend, it will send me the ScheduleEvent object, but once it got to the flex side (via BlazeDS), it becomes a StartEvent....
At first, I thought it's because these two events have exactly the same variables, so I tried changing ScheduledEvent by adding a dummy variable (String foobar) but that didn't seem to make a difference.
EDIT: I'm using BlazeDS messaging system.That's why I am not using "one java method call to one responder" approach. So, in the message.body, I should be getting ScheduledEvent but I keep receiving StartEvent. I'm wondering if it's because the two objects have the same property and BlazeDS doesn't know how to map them correctly... I even put a break point in the java service layer, to make sure that the appropriate object is being sent back and it is... But by the time BlazeDS serializes and deserializes it to the flex side, it is now a StartEvent.
