RE: [flexcoders] Re: Open source AMF solutions that work with flex
Just FYI: Flash 8.5 Player supports GZIP compression in the Socket Class. Ideally using plain XML, you can exchange GZIP'd XML binary files thus compressing the data exchange both ways. Also given that XML Parsing in 8.5 is much faster than 7/8 generation players, we will see data exchange with 8.5 become a more level playing field. Plus with E4X exchanging raw XML in a custom format is far simpler that it used to be. We will see an explosion of data exchange technology with F8.5. In the end, I think the technology choice is more appropriate to what skill set you have in-house. There are a ton of great Web Service development tools, where AMF only resides within the Flash space. Having worked with Cynergy on a Flex/Web Services project with hundreds of transactions per session, Web Service with AXIS/Tomcat is rock solid. Plus you really cannot beat free in this case especially in regards to scalability.

Re: [flexcoders] Re: Open source AMF solutions that work with flex
Robert, 1.AMF uses less bandwidth over "fully quallified" SOAP requests for simple data types. In XML over HTTP scenarios you can provide better "packed" and more compressible formats. Example of such might be placing your data for tree control not in the nodes, but in attributes of the node. That also means that you need custom code that would convert such packaging to the dataproviders/destination objects. That piece of code is called client proxy and it knows a lot about the types and names of the server and client structures. That code tends to simplify parsing and creation of destination objects by examination of incoming data and creation of larger objects/precompiling access methods. You can also create proxy code for AMF by using Object.registerClass and in my tests it decreases the load time by 40% on large data sets. 2, There is a lot of development in the area of E4X - essentially complementing scripting languages by XML-based data structures. As Flex 2 rolls out support for that you might see completely different creatures in the "object" hierarchy - like tree/datagrid combinations or grouped reports/databound controls. You should also be able to expand elements more freely - by adding attributes to the elements - thus tracking statuses or expanding dataProviders on "per item" basis. If your targets/timeframes are aligned with Flex 2 that definetly deserves second look. 3. Main advantages of SOAP at this point are in interoperability. That is no different from coding in SQL as oppose to (may be faster ) native API of a particular vendor. People are asking about integration of AMF with PHP, Perl and other environment - while with SOAP that is non-issue. 4. I use AMF for most of my server interaction in Flex due to built in support and shorter learning curve for new developers that have to accept the code for maintenance. However, I believe that client/server interface is probably the most "breakable" piece of code due to the fact that ActionScript does not see host environment and can not check for typos/type correctness and vice versa - you WILL spend hours figuring out why AMF method throws an error. As a result I generate most of the interface code and package it as custom class(es). As a result, I can code against strongly typed structures that are always up to the date. As soon as you start to generate the code, it is a small incremental effort to generate it for different types of services (AMF or SOAP or your own/future ones). One interesting twist to that to generate proxy code that does not require WSDL and is precomiled for fast execution - giving you comparable performance to the AMF 5. Coming from the environments that gave me complete control over HTTPRequest, synchronous/asynchronous communications etc, I like to keep my options open. In most cases it means to keep backdoor to JavaScript/MSXML open - trading portability for performance and flexibility is a good option to have Sincerely, Anatole Tartakovsky - Original Message - From: "Kevin Langdon" <[EMAIL PROTECTED]> To: Sent: Saturday, October 22, 2005 8:52 PM Subject: RE: [flexcoders] Re: Open source AMF solutions that work with flex > Robert, > Flex supports a number of ways to transfer data between client and server. > The most common ones are AMF (mx:RemoteObject) and SOAP (mx:WebService). > As > with any two technical solutions, some engineers just generally prefer one > of the other.

RE: [flexcoders] Re: Open source AMF solutions that work with flex
Anatole, 1. Yes I am very aware of how Firewalls and Proxies can wreak havoc on binary streaming protocols. AMF is not a binary streaming protocol, its simply a stateless HTTP POST of data. If a firewall can't handle AMF then it will likely have problems on things as simple as multi-part form POST. 2. This is a mute argument. Your standard AMF packet is smaller than a similar SOAP envelope. Yes, if you GZIP the SOAP it will be comparable to the AMF packet. But you can also GZIP the AMF and then it is that much smaller yet. 3. Your talking about the speed on the server side. The issues are in the speed of parsing on the client-side. The simple truth is that it will always take longer to parse XML compared to a binary protocol. In one I have a string that I need to check every character for a tag close. In the second I have two bytes that tell me exactly how many characters to read in. I think there are many times when SOAP is a better solution than AMF. SOAP has much better support and community around it. Its much easier to debug. When dealing with 3rd parties SOAP makes much more sense. What I am arguing is that if performance is your top priority, AMF is a better solution. And I don't think that its relationship to SOAP has anything to do with Java's relationship to Assembly. It is not difficult to abstract your code in a way that allows you to easily toggle between SOAP and AMF or even have both working in parallel. It is worth the effort to do this to ensure that you can benefit from both protocols in different situations.

Just let me note that Dave's experiences were independently seen in our apps as well as we were doing a lot of proprietary remoting over HTTP in the last 7 years for RIA type of applications. Here are the results: 1. Firewalls will through some problems. Much more will come from proxy servers. HTTPS/keepAlive bugs in apache and clones will add theirs. There are bugs in URLMon ( Microsoft module that handles HTTP streams) with handling large compressed streams that will make you loose your sleep. You want your protocol be as much debuggable and configurable as possible - preferably on per client basis - to be able to send data differently to Japan or New York. 2. GZip is a huge win for relational type of info (DataGrids and lists). AMF Remoting does not remove metadata info - and with GZip the package size of XML output should be comparable. 3. Main difference in the speed is in the way AMF "optimistic" approach works. You send request to the server and it tries to introspect Java classes and find best match (by doing comparison of all methods signatures) - and all that is somewhat optimized and cached . Obviously all metadata - including field names and types - travel with the package. When it comes back - the same deal here - either it uses packet metadata to create dynamic object or reconcile it with registered class. I personally had quite a few cases when AMF diagnostics of the protocol problems required me to debug flashremoting servlet. Compared to other protocols I have seen there is no magic - just a good implementation of serialization / deserialization machanism (I might of missed something though) with very few basic types - and that is not different from any other proprietary protocol Dave is refering to. Webservices usually requre 2 roundtrips - one to get metadata and create "client proxy" and one for actual code execution. Good implementations suppose to cache the first call thus making that cost negligible. Client proxy can be made more efficient then dynamic built-in one. The benchmarks creation is a separate art form - and is too often in line to what we expect to see. If I was serious about performance I still should be coding in Assembly language. Chances are that most of us code mostly in Java or scripting environment. Personal note: There pros and cons for use of XML to serialize ActionScript objects misses the point that XML is the universe of it's own. I hope that with E4X in the core product people will gradually get in more complex data models that will move this discussion from comparison simple "POC" apps to real world ones. As you move your application towards use of stateful datasets and other large transfers you will find yourself using HTTPRequests and WebServices more often.

I personally had quite a few cases when AMF diagnostics of the protocol problems required me to debug flashremoting servlet. Compared to other protocols I have seen there is no magic - just a good implementation of serialization / deserialization machanism (I might of missed something though) with very few basic types - and that is not different from any other proprietary protocol Dave is refering to. Webservices usually requre 2 roundtrips - one to get metadata and create "client proxy" and one for actual code execution. Good implementations suppose to cache the first call thus making that cost negligible. Client proxy can be made more efficient then dynamic built-in one. The benchmarks creation is a separate art form - and is too often in line to what we expect to see. If I was serious about performance I still should be coding in Assembly language. Chances are that most of us code mostly in Java or scripting environment. Personal note: There pros and cons for use of XML to serialize ActionScript objects misses the point that XML is the universe of it's own. I hope that with E4X in the core product people will gradually get in more complex data models that will move this discussion from comparison simple "POC" apps to real world ones. As you move your application towards use of stateful datasets and other large transfers you will find yourself using HTTPRequests and WebServices more often.

Dave, Do you have some kind of example of the app you are referring to? I'm not being so absurd as to ask if you could share with the group your app; but mainly your experience and perhaps any samples you found or created early on to learn AMF. -r --- Dave Wolf <[EMAIL PROTECTED]> wrote: > > > ever coded a flex app using web services?

There's enough to do, enough to learn and enough to get done in the day w/o messing aroung with half a dozen or more integarated technologies.

Re: [flexcoders] Re: Open source AMF solutions that work with flex
Speakning of the HEX and ASCII you mention below, I would assume that AMF is cross-platform, and that a developer such as myself standardizing all projects on it, will also be able to use Flash for Mobile Devices when (currently called Flex Lite; though I realize it's not exactly like the current version could do this; but is it possible and will it happen!). --- Dave Wolf <[EMAIL PROTECTED]> wrote: > --- In flexcoders@yahoogroups.com, "Abdul Qabiz" > <[EMAIL PROTECTED]> wrote: > > > > Hi, > > > > > > > We actually used to tunnel the IIOP through HTTP > a lot to avoid this. > > > > AMF packets also go as HTP POST.

RE: [flexcoders] Re: Open source AMF solutions that work with flex
The presentation that I gave at MAX (and now linked from my blog http://weblogs.macromedia.com/mchotin) has a discussion of choices for accessing data. I also have a discussion in there (sometime much earlier) about the GZIP compression experiments that some of our QA did. The serialization that Abdul is talking about is for strongly typed classes, our XML deserializer does not currently map AS-classes to schema types, there is no wsdl2as-like functionality.

RE: [flexcoders] Re: Open source AMF solutions that work with flex
Seems to me serialization is a huge benefit, and in re: to performance, certainly important (XML has this problem to in large datasets and/or requires consideration in design). This is interesting to me (btw, do you have any URLs to information on it)but one concern as always is adoptation of it. If you standardize on AMF and create a library of web services and then it fades away; not good. -r --- Abdul Qabiz <[EMAIL PROTECTED]> wrote: > Hi, > > AMF has lots good things, I know some of these: > > * Binary transport > * 50% percent faster then SOAP or Webservice > * Automatic object serialization/deserialization > > > -abdul > > > > -Original Message- > From: flexcoders@yahoogroups.com > [mailto:[EMAIL PROTECTED] On > Behalf Of Dave Wolf > Sent: Friday, October 21, 2005 12:29 PM > To: flexcoders@yahoogroups.com > Subject: [flexcoders] Re: Open source AMF solutions > that work with flex > > I do want to know why you're prefering AMF over HTTP > or WebService. > > Just curious on the motivation there. > > -- > Dave Wolf > Cynergy Systems, Inc. > Macromedia Flex Alliance Partner > http://www.cynergysystems.com > > Email: [EMAIL PROTECTED] > Office: 866-CYNERGY x85 > > --- In flexcoders@yahoogroups.com, Clint Modien > <[EMAIL PROTECTED]> wrote: > > > > I guess I should specify that they don't need to > be open source at > all they > > could be 3rd party as well.
