An introductory article on using FR with Java, including a simple example of creating XML in Java, passing it via FR, and parsing it in Flash.

A new open source project called ASTranslator solves some problems in Flash Remoting's default behavior when translating Java objects into ActionScript objects. Briefly, FR exposes private properties, breaking encapsulation. ASTranslator prevents this. More info here.

The simple summary: If you're having problems maintaining a connection to an EJB from a single-frame movie, add a few extra frames.
The technical explanation: Due to some glitch, this allows you to call methods on the NetServiceProxy object that acts as a client-side reference to your EJB. (The NetServiceProxy object is the result of the call to the EJBHome's create method.)

If you develop apps using the trial version, get downgraded to the developer version after 30 days, then buy a license, you may find that your apps still only work with one IP address. Here's the fix: Update your apps' license files (/bin/frconfig.txt) so that the license number matches the one found in Macromedia's sample apps' frconfig.txt file. Each app must have a valid license file. For some reason, the installer updates the samples' licenses only.

It appears that if you're not using the JRun version of Flash Remoting, passing RecordSets to a Flash client fails unless the ResultSet is still connected to the Database. As leaving ResultSets connected to a database is a truly bad practice, passing Java RecordSets via FR (without JRun) isn't practical.
Our Slideshow Demo's Java code shows one possible workaround using CachedRowSet instead. This returns non-fatal errors but seems to work otherwise.
Another workaround is to translate your RecordSet into Arrays, pass the Arrays, then translate them back into Flash RecordSets once they arrive at the client.
Rumor has it that Macromedia will be releasing a patch that supports RowSets and fails more gracefully for ResultSets sometime soon.
If you have information on other possible workarounds, please send us a post.

Apparently RecordSet paging is currently a ColdFusion-only feature. This leaves a fairly big hole in the Java/.NET implementation of Flash Remoting (including JRun). Many components, such as ListBoxes, that require a RecordSet DataProvider won't work properly. (For more details on RecordSet DataProviders, see RecordSet.as and RsDataProviderClass.as in your FlashMX:Include folder)
The following workaround has been suggested, but we haven't implemented it ourselves: Build the functionality yourself as another Flash Remoting service and set the ActionScript RecordSet instance's "serviceName" property to the name of the service that can supply subsequent pages of ResultSet data.
If you implement something like this, we'd love to post some sample code.
We hear rumors that Macromedia's next patch will correct this.

Coming in November from Friends of Ed. The blurb says "Flash Remoting is not the only way to combine [Flash MX and .NET] however, so this book will fully cover Flash/.NET integration using ASP.NET."

...by Mick Robinson of MapCloud. Focuses on Flash and JRun, but much or all of the materal is applicable to other J2EE platforms.

Macromedia has just released Flash Remoting for .NET and Java, previously code-named Salsa. This will allow us to connect our Flash movies to .NET and J2EE platforms other than JRun.
Cost: $1000 per CPU
General info can be found here, technical specs here.

MMBUG Slideshow
Demo - Flash Remoting
with Java & .NET
Why Flash Remoting
Matters
Macromedia's MX product
line makes it possible to create Rich Internet Applications (RIAs) using Flash.
We won't attempt to go into detail about why RIAs are important here - Macromedia
has a fair amount of information
on the subject. Suffice to say that Flash is maturing into a true application
development platform, with substantially better ease-of-use than standard web
pages, and a larger installed base than Windows, Java, or any other platform
(Flash has 98% penetration).
Flash Remoting is a
key MX feature because it makes it easy for Flash applications to access and
interact with server-side data. Using Flash Remoting, your application can do
all of the following:
- Easily access
web services. If you aren't already familiar with web services, and define
yourself as a geek, you need to learn about them. They're becoming the standard
technology for sharing information between applications over the internet.
This article
at Web Services Architect
provides a good general overview.
- Easily access server-side databases.
As this article is targeted at geeks, we'll assume that you already understand
the myriad of ways in which this can make your applications more useful.
- Pass complex objects from server
to client, and vice versa. Yes, you too can take a complex Java or .NET object
and pass it into Flash with all its properties intact. (Methods are another
matter, but let's ignore that for now.)
In short, Flash Remoting will make
it much easier for you to create powerful, useful applications.
Goals Of The Demo
Our primary goal in
creating this demo is to help you start creating Flash Remoting applications.
Macromedia offers lots of resources that will help you to do this with ColdFusion
on the server, so we're focusing on Java and .NET. We also
provide ColdFusion code so that you can compare it.
We provide a sample
application that will run with all three server-side platforms. The application
demonstrates accessing a server-side database and accessing
a web service. In both cases we keep the functionality quite simple
and leave it to you to imagine more complex applications. You should be able
to get it up and running on your platform of choice, then play with it and extend
it.
After
that it's up to you. As you make exciting discoveries please consider submitting
them to this blog at FRJNblog@mmbug.org.

Macromedia's Blackboard case study is a goldmine of information on implementing Flash Remoting with Java. I particularly like John Bennett's Designing Java Applications for Macromedia Flash Remoting article, which includes:
- Great diagrams detailing Flash Remoting's architecture
- A lovely debugger's-eye-view of an object's arrival from the server, with all its properties intact
...but there's a lot of other material, and source code.
Blackboard Inc. provides Java based e-Education infrastructure to educational institutions. The demo details how they converted a group management tool consisting of several HTML pages into a user-friendlier Flash application.

The online Flash Remoting documentation appears to be a more recent and more complete version than that contained in the PDF version, and has a lot of useful information on Java and .NET.

Macromedia has announced "ColdFusion for J2EE". While not a Java development environment, it may still be of interest to Java developers. The standard version of ColdFusion is built around a JRun core (Macromedia's J2EE container). In contrast, ColdFusion for J2EE can be installed on top of other J2EE containers - specifially Sun ONE and IBM Websphere - which opens the door to deploying ColdFusion in these environs.
Developers in Sun and IBM shops can now create Rich Internet Applications using Flash Remoting. ColdFusion easily uses Java assets, and Flash Remoting simplifies the connection between ColdFusion and Flash. You can get more information on the advantages of this arrangement in this article by James Hurff and Sun's article on Macromedia's Pet Market.

Hi,
This blog is a project of the Macromedia Boston User Group. Our goal is to serve as a resource for developers who use Flash Remoting with Java or .NET.
We invite you to submit posts to this blog. For details, follow the Welcome link on the right.
