Flex/BlazeDS and integration of FileNet
I can successfully create a session FileNet Process Engine via my backend of java code, but the session is not maintained alive while the flex application is open. What is the best practice to keep the 3rd party sessions open for the duration of the lifetime of the connection application? What would be the best way to go about this problem?
From now on, the connection is established by calling a particular method on applicationComplete and, possibly, by the action of button click. Resolved - I just had to clarify the scope of the destination "session".

Explicitly mapping between objects ActionScript and Java to BlazeDS Messaging Service
BlazeDS documentation shows how to map explicitly between ActionScript and Java objects. For example, this works very well for RPC services, for example
import flash.utils.IExternalizable;
import flash.utils.IDataInput;
import flash.utils.IDataOutput;
[Bindable]
[RemoteClass(alias="javaclass.User")]
public class User implements IExternalizable {
public var id : String;
public var secret : String;
public function User() {
}
public function readExternal(input : IDataInput) : void {
id = input.readObject() as String;
}
public function writeExternal(output : IDataOutput) : void {
output.writeObject(id);
}
}
and
import java.io.Externalizable;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectOutput;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;
public class User implements Externalizable {
protected String id;
protected String secret;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getSecret() {
return secret;
}
public void setSecret(String secret) {
this.secret = secret;
}
public void readExternal(ObjectInput in) throws IOException,
ClassNotFoundException {
id = (String) in.readObject();
}
public void writeExternal(ObjectOutput out) throws IOException {
out.writeObject(id);
}
}
If I called a RPC service that refers to a user, the secret is not sent on the wire. Is it also possible to do this for the e-mail service? In other words, if I create a custom message adapter and use the function below, also prevent secret to be sent?
MessageBroker messageBroker = MessageBroker.getMessageBroker(null);
AsyncMessage message = new AsyncMessage();
message.setDestination("MyMessagingService");
message.setClientId(UUIDUtils.createUUID());
message.setMessageId(UUIDUtils.createUUID());
User user = new User();
user.setId("id");
user.setSecret("secret");
message.setBody(user);
messageBroker.routeMessageToService(message, null);
Hi Martin. The way the serialization/deserialization AUTHORITY works for BlazeDS is the same regardless of service is used, then Yes, that code will work for messaging as well. On the server, the serialization/deserialization of messages coming to the endpoint. For an incoming message, for example, endpoint deserializes the message and passes it to the MessageBroker who decides what service/destination to deliver the message to.
That is a good question. Thank you for asking. A lot of people is used to make custom services (RemoteObject/RemotingService) RPC serialization/deserialization but I'm not sure that everyone realizes that they can do this for messaging as well.

I can't plug ins for Adobe and Java
When I try to upgrade Adobe Shockwave and Java I am directed to "http://helpx.adobe.com/security/products/flash-player/apsb13-28.html" I'm on a mac os 10.7.5.
Sometimes sites checking plugin link to the release notes of an update instead of the installer. Not sure why this is happening. Here are some alternatives:
Flash (Shockwave Flash) Player: http://get.adobe.com/flashplayer/ (be sure to uncheck all the unwanted before downloading extras)
Java plugin: http://www.java.com/en/download/installed.jsp (be sure to uncheck all the unwanted when installing extras)

Exception handling between flex and java (BaseProxy)
Hello
In my plugin code, there are several calls between actionscript(Our View) and java(Service layer) along the lines of the example of chassis (createChassis/deleteChassis/editChassis, etc.). However, the only difference is that in our service layer, we can be thrown exceptions, and I don't see what is happening in the examples of chassis/Rack. If the reminder in actionscript gets called in an asynchronous way to update the user interface when a method returns, which is good; However, if something goes down into the java layer, I wonder how I can connect this exception to the wire on the side of the actionscript. The MethodReturnEvent reference is an event.error but which seems to have no knowledge about what really happened on the java service layer and I couldn't understand how to share this information with actionscript (in case of failure). Before you build another layer to manage exceptions, I was wondering if there was all recommendations of the team of webclient on how handle java exceptions and pass information from java to actionscript to handle additional failure in actionscript (perhaps show a dialog error saying something is is wrong and how remedy).
Thank you.
In this case, see the global services-ui and Global Services-service examples that are provided with the SDK. There examples you're looking for.
See especially pass method and the call for return.

Flex application and several basic material
Hello
my company is developing an enterprise application pretty huge involving 4 Flex, BlazeDS, a server side Java-spring and frame matte on the client side.
It works very well but as demand is growing bigger and bigger performance problems are a major concern for us... And our customers!
We just noticed a performance problem and I could not find any resource from Google, it's here:
It seems to us that no matter what the number of CPUS of your computer has, our Flex application always use only one. Accordingly, our application rolls over on a P4 core at 3 GHz computr processor than, say, on a core i7 with 8-processor 1, 6 GHz! Pretty strange isn't it?
However, I learned that multicore of handfuls of Flash Player since version 9, so perhaps am I missing something simple? Is there something I should do to enable multicore processing? What is my application which is poorly designed? Or an operating system issue maybe?
Any help would be greatly appreciated
Thank you
Matt
ActionScript is single-threaded, so there is no advantage to try to spread his treatment between multiple cores. Once the actionscript code has implemented the displaylist for a framework, certain aspects of the rendering of the display list can be distributed to the other cores or even a gpu. Use the performance profiler to see where you as usage patterns are expensive and optimize.

Export DataGrid data to the file with JSP and Java
My user must be able to load the data into a spreadsheet. I would like to stay with Flex and not use air. I used the windows clipboard, but I experience delays of Flash Player for the largest data sets if the closure of the DataGrid rows takes longer than 2 minutes. I would like to do with passing data to a JSP page or use BlazeDS and then download the file. I would just pass the ArrayCollection collection so I don't have to loop through the rows of the DataGrid. I know that I can receive a Java ArrayList using BlazeDS and it gets converted to an ArrayCollection collection. Is it possible to send an ArrayCollection collection to a JSP page or class Java with BlazeDS? If you want to use JSP and Java, I presented the following article on the Flex Cookbook site that explains how do.

Flex + BlazeDS
Hello, friends!
I am new to Flex and Java.
I tried the simplest tutorials ( http://www.adobe.com/devnet/livecycle/articles/blazeds_gettingstarted.html), and strives in giving, but I cannot put Flex working with the BlazeDS.
I post my doubt on BlazeDS forum, but nobody has yet responded.
The question is: when I run my MXML app, I can see through the Firebug occurring on the 404 error (not found) "" http://localhost: 8080/myfirst/messagebroker/amf ". "
So far, I don't even know if the problem is on my application MXML, on my Java classes, in my server or xml configuration files.
Anyone know where could be the problem? Or someone could signal a beginners tutorial Flex + BlazeDS?
Thank you
CaioToOn! Thank you all for the reply!
I realized what the problem was. When I did the tutorial for the first time, I put a destination with the name 'tutorial-product' in the XMLs "messaging - config.xml" and "remoting-config. XML ".
Then, when I tried to start the server, it crashed, but with my lack of knowledge in Java, just now I realized that I could solve something by reading the "echoes" of the initialization of the Java Server...
In any case, thanks for the help nintendofanboy8, the book is really good!
Kind regards
CaioToOn!

The Java platform and Java deployment should be updated but there is no other version, always careful to update, but it is not possible
Platform Java 7u9 and Java plug-ins Deployment Kit are yellow and asked to be updated.
The problem is that there is no other version I've already installed.
Even if I try to install this latest version once again I get the message that I already have the latest version.
The same problem was with Flashplayer where I installed the latest version, but Firefox has asked three days update the plugin.
The last is now ok, but the Platform Java and Java Deployment Kit is hopeless.
Why he request an update if there is none?
What should or can I do? I always be careful and patch my pc if necesserry.
All my friends who work with Firefox have the same problem.
Can someone tell me what is happening here?
Greetings, Mimi321

Firefox and Java
I use Windows XP Pro and Firefox 41.0.1.
Is there a problem with the Java site when you use the 41.0.1 Firefox Version?
When I go on the Java site to check the latest update of Java is installed, the box does not analyse the last update. I checked that the last update for Firefox was installed, deleted cookies from Firefox and closed and reopened Firefox but the Java Web site does not work.
Anyone aware of this problem?
However, I can go in 'Modules' in Firefox to check that plug-ins are up-to-date or manually check the site downloads Java for the last Java version., that which I did, and Java is up to date.
Your question is for Mozilla, not Microsoft. This isn't something that has caused or affected by the operating system.

Flex - explanation of Java
We know all that you can have a class ActionScript that "maps" to a Java class and there are converted from Flex Java and Java in Flex, but nobody knows how this conversion is made? We also know that properties must have the same name on both classes, but what if there are getters and setters? What happens if I don't "map" a property? and these questions
I would be grateful if someone could explain how Flex converts to Java and vice versa.
See: Flex 2 Developer's Guide > Data Access and interconnectivity > configuration of Data Services > data serialization
Also do a search on java in the livedocs Flex 2.0 to get all the information.
The Flex Gateway uses Java reflection to determine what to match.
