Laszlo Systems has made the announcement that their Laszlo platform is now open source. The entire platform has been released under the Common Public License (CPL), which means you can build commercial solutions on top of Laszlo. The company itself will now try to make money on services, support, and commercial app development.
Laszlo applications are written in LZX, a standards-driven XML and JavaScript description language that enables a declarative, text-based development process. LZX supports rapid prototyping, collaborative software development and long term code maintenance.

Very nice. I look forward to playing around with this.
My one immediate concern (as with all web UIs based on Flash), is w/regards to the ability of users with poor eyesight (I fit in that group) to customize the font sizes used within the UI.
For a normal HTML based web-site, Mozilla allows me to easily resize _all_ fonts in the web page to something larger, even if the designer used tiny, normally fixed-size pixel based fonts. Native apps (i.e. Windows, MacOs, or Linux based apps) also allow you to set font sizes (indirectly) since they will generally respect the font settings you have set at the OS level.
On the other hand, when I was trying out all the Laszlo demos, I did not see any ability in any of the apps for users to scale fonts to their own needs. Does the Laszlo platform make it possible for apps to allow users to easily (dynamically, or on a per-user basis) change font sizes?
Regards,
Colin -

Lazlo, Flex, Testing[ Go to top ]
- Posted by: Howard Lewis Ship
- Posted on: October 05 2004 12:27 EDT
- in response to Dion Almaer
I took a cursory look at Lazlo (and at Flex). I'm very interested in these technologies, especially in concert with Tapestry.
In any case, my concern for these technologies is group developement, debugging and testing.
To what degree can you split up a Lazlo UI into smaller pieces (perhaps as different tabs within a master interface) and allow different developers to work on the whole? What are the choke points? At what point does the generated Flash file become too large, or too slow to generate? Alternately, can you have different web pages hosting different UIs and easily chain between them (passing state as needed)?
What kind of error reporting is built into the Flash side? Can you enable a debug mode? A full debugger? Error reports back to the server?
If you put UI/business logic into Flash as JavaScript/ActionScript ... can you unit test it? Is there a simulated Lazlo client container so that you can test your code non-interactively?
I'm setting a high bar here; at the level I'm looking at it, Lazlo and Flex seem quite equivalent (though I found the Lazlo interface a little more snappy).
BTW ... Flex had a skinning/L&F feature, how does Lazlo compare? -

Great questions!
"To what degree can you split up a Lazlo UI into smaller pieces[?]" Laszlo development is designed to be broken down as far as needed. Since the whole thing is built in LZX (XML + ECMAScript) you can have some developers working on the UI logic and others working on the business logic. Your example of some developers working on the tabs is a good example. The Laszlo Component set is built this way. One group develops the UI classes, publishes the API and another group can use them easily. LZX is OO so the best practices apply.
"At what point does the generated Flash file become too large, or too slow to generate?" The LZX compiler caches much of the compiled code so incremental changes don't have a large affect on the compilation speed. I don't think there's a good answer to this. There's some really big apps out there that compile and run in seconds. I've written apps that take quite a while to start up but we later optimize those cases using the Krank Optimizer.
"Alternately, can you have different web pages hosting different UIs and easily chain between them (passing state as needed)?" Yes, in much the same way you would now. The La Quinta mapping app does this (here) state (no pun intended) is passed to an external app and back again.
"What kind of error reporting is built into the Flash side?" There's an integrated debugger that you can use to watch for internal events. For the reast: Yes, Yes and Yes.
"can you unit test it?" Yes, there's a test component simmilar to JUnit that ships with the server called LZUnit. As for the second part, I think LZUnit fits that bill.
"Lazlo and Flex seem quite equivalent" Not any more :) -

Laszlo and MVC frameworks?[ Go to top ]
- Posted by: Julien Dubois
- Posted on: October 05 2004 19:13 EDT
- in response to Dion Almaer
Laszlo looks really cool indeed.
Laszlo can access dynamic data in the form of an HTTP request, fired up from the Laszlo GUI, to a JSP/Servlet that will render data in XML format.
From the documentation (http://www.laszlosystems.com/lps-2.2/docs/guide/data_app.html), it seems that Laszlo would work well with Struts or WebWork. In fact, the horrible example that is shown would look a lot better with Struts or WebWork.
It could be an exciting view technology to use, but I'm worried about the fact we now use a JSP/Servlet as a DTO... Very weird....
Does anybody have any experience with this? -

Congratulations to Lazlo, seems like they've made great move to spark interest for this technology.
Now what I would be very interested would be to look if this framework could be integrated with Java Server Faces. Maybe doing custom UIComponents in JSF to map to the rich Lazlo components and then make several RenderKits to render out to both Lazlo LZX and HTML and maybe Flex?
Maybe the guys at Lazlo Systems have had similar ideas or even someone else?

Congtratulations on a developing such a professional product.
I just have a few questions...
How difficult or easy is it to add new components to the system?
Can you fade components in and out ( I couldn'd find info about it in the docs )?
Can you develop systems to take advantage of improvements made in the latest Flash Player, ie. improvements in the quality of video playback? -

Quick Flex vs Laszlo[ Go to top ]
- Posted by: Tom Eugelink
- Posted on: October 06 2004 02:31 EDT
- in response to Dion Almaer
Did a quick comparison of Flex vs Laszlo and they are, as a whole, competative. I find Laszlo less strong (and if it turns out that I'm wrong, atleast in the documentation area) in the integration. Laszlo can do regular HTTP get/post, but there is no alternative for Flex's fabulous remote object AMF thingy. And, although less important, the integration of Flex in JSP using taglibs. And there is no builder as far as I have gathers (debugging is done "in application").
So I must conclude that Laszlo is great but Flex appears to be a tad more great. And that means that, things being as they would be, customers would choose Flex over Laszlo (probably if they were exactly alike, customers still would).
So one option for Laszlo would be to compete with Macromedia on features... Ahhhhhhhhh. Probably unwise, since MM owns Flashplayer and suddenly Microsoft tactics come to mind. Or remove the other big factor: money, making things unequal again. Have to compliment the Laszlo management on this insight and daring to make preemtive choices! -

Huge congratulations to Laszlo!! This is an inspired move!
I have tried Flex + Spring + Hibernate, and it is very nice, so am looking forward to Laszlo + Spring + Hibernate. My only dislike of Flex was that any client-side code had to be written in ActionScript.
Is there the ability in Laszlo to write client-side code in Java? -

I chose Flex when looking at these 2. Flex has a bit to go to be truly excellent (file upload, listening to server events[you can do this with another add on from Macromedia], more of the html tags to embed into flash widgets) but macromedia is on the job and I think in the next few months we'll see changes and great things from the good people there.
With laszlo I would like to see integration with XAML, but I still love Flex.
Also for issues of speed such as the "AMF thingy" why not put a gzip compression over the http request? I did this with AMF and got 88% compression ratio of my data. Speeds it up considerably. I only compress the /amfgateway/* on flex.
Also maybe introducing openAMF into Laszlo would be good. Open source helping open source imagine.
http://www.openamf.org/ Don't know if it could be done but someone should try.
No i don't work for Macromedia, but I do respect anyone who deals with me openly and honestly and that's what I have received from Macromedia, good customer service. -

Maybe Hessian or Burlap support would be good for client-server communication?
as far as i understand laszlo architecture description, laszlo uses it's own protocol for client-server communication, which is optimized for performance. i guess the mechanism might work like a proxy to remote services via xml-rpc or soap. -

Why not? In the demos I see that the components for the user interface are quite complete (the contact demo looks like a normal Swing/SWT application). I surely prefer to write my contact application using Laszlo now (instead of Swing or SWT), since it is still based on web browser (+ flash plug-ins, everyone uses this plug-in anyway). And now because it is Open Source I can imagine that many developers will add a lot of components to Laszlo.
IMO, the fact that Laszlo is Open Source will push this type of presentation layer development to the edge...

ok, i haven't put it right. it might be targeted for all kinds of applications, but the main motivation for using it (rich gui experience) is most important in case of front office applications. in back office there is no such a strong need for rich interface (html is enough), so there's be no push for using it.IMO, the fact that Laszlo is Open Source will push this type of presentation layer development to the edge...Lofi.

I'm not sure if it's possible (and makes sense). JSF supports traditional web development as it uses page-oriented approach. Laszlo does not. Quote from the guide:This is a very great news! No need to do those HTML stuffs anymore. Forget JSF, JSP whatsoever!Lofi.

"With Laszlo technology, web appllication designers are freed from the familiar limitations of static, linear, page-based task flow. [...] One of the key benefits of using Laszlo to build your project is its strength in consolidating information through interaction and presentation. A process that might have taken 20 html pages to accomplish for the very patient user, might now be designed to occur within the framework of a single "page" with small bits of information elegantly surfaced as needed.

Perhaps we should remember that Java has its own browser solution that can build RIAs - Applets. And there is an excellent toolkit as well, not swing, not AWT, not SWT, but Thinlets. http://www.thinlet.com.
My opinion remains that Flash is useful for consumer based websites where graphics and marketing people dominate, but Thinlets are much more useful for serious business applications, like configuration, database management, in fact anywhere where the RIA is not just exposed over the internet to the general pubilc. -

Yes, I think this is a matter of using the right tool for the right job. We cannot simply say that which technology is better. We've been using Thinlet for data entry intensive purpose for our intranet (where we can limit the choice of the browser to IE, Netscape and Mozilla) with very good results. On top of that, you have an end-to-end J2EE-based OO solution throughout which is not possible with flash. But for public sites, I agree that flash is a better choice.I tried some thinlets and had problems within Konqueror and Firefox in Windows (because of JVM issues).

Why target Flash?[ Go to top ]
- Posted by: Ed Burnette
- Posted on: October 06 2004 10:38 EDT
- in response to Dion Almaer
The answer that is normally given is that Flash has great reach, runs in 97% of browsers, etc.. But it wasn't always so. People installed Flash because they ran into web sites that used it, it was easy to install, and the content was cool. It's a testament to its flexibility that you can use it for something like rich clients for which it was obviously not designed. Are we stuck with it though? Is there something that exists now or could be designed that could be as easy for the end user as Flash but more suited for rich client applications? Given its architecture, Laszlo can render into other client-side environments. Question is, should it and will it? I suspect they're thinking about targetting some kind of enhanced what-wg HTML at a minimum. -

I've actually used Laszlo with a Cocoon backend. You can see a few details about this on the laszlo discussion thread: http://www.laszlosystems.com/developers/community/forums/showthread.php?s=a322e3ad9d798791214bacc5985d6c92&threadid=887
I used Hibernate on the backend for storage and then put Cocoon between it and Laszlo. Overall, it worked quite well. Cocoon is about the only way I could find to publish XML for Laszlo to use with the exception of using XML generated from JSPs as the Laszlo documentation suggests. I managed to get Laszlo to integrate with Cocoon's authentication framework as well. I just wish Cocoon did not have such a steep learning curve because debugging your work in Cocoon is a little difficult.

I couldn't think of anything worse! XML is fine in very small doses, I would run a mile from an alomst complete XML solution. I've created a servlet that uses XStream to convert the objects from my struts application to XML which works fine without the compilcation of using cocoon.
Of course, if XML is your bag, then fill your boots ;) -

XStream might have worked great, but I wasn't familiar with it at the time. Cocoon makes a good layer for producing XML if you need it for lots of different destinations (FOP/WML/XHTML etc), but if you only need XML for supporting Laszlo, XStream might be the ticket. Can you elaborate on your XStream solution or was it a pretty standard implementation? -

To migrate a small section of an existing application, all I did was update the struts config to forward objects in the request to the servlet. The sverlet looks for the values and creates an XML representation of them.
In your case, where you want to create different forms of XML, XStream would not be of any use. But it allowed me to test Laszla quckly with an application I was familiar with.
I also had to assign 512mb of RAM to get Laszlo running, I haven't tried to remove much of the default installation, nor have I profiled it under any load. My first impression is very positive, tho. The documentation is first class, and it it fairly simple to get up to speed with the interface code. -

Did you use the Tomcat installation that comes with Laszlo or deploy it on your own Tomcat installation? The release notes mention that the version of Tomcat that comes with the Laszlo installation has tweaked memory settings to avoid out of memory issues. You might need to apply those settings to your own Tomcat installation if you didn't use the one that ships with the installation. -

Bill,
We have a light weight and powerful XML mapping component we've been very heavily using on our project for almost 5 years. I was reluctant to open source it because lack of time I can allocate for maintenance, documentation etc. I am not sure if I would do it now but if you are interested please contact me directly <shurik AT peacetech DOT com>
Basically you define your XML-Database mapping in XML schema file and then can run query against it choosing only elements you want. Engine will optimise database access including table joins based on elements selected. Output is SAX stream. It integrates with another very light weight component - Schema/Query caching framework, XSL stylesheet caching. JSP tags and servlet to access the functionality are provided
Here are some features of XML mapping component (XMAP):
Mapping via Named and Anonymous Xmap Types. Types can be extended and their mapping properties overridden on any level. Abstract Types are supported
Transparent support for multiple data sources. Data from several databases can be combined into a single Xmap Type
Intelligent SQL mapping whenever possible assembles data from multiple tables into a single SQL select statement. Only data elements requested by Xmap Query will be retrieved from database not entire Type.
Role based and Callback based Security on XML element/attribute level
Special mapping constructs - Variants, Composite Elements, Containers for greater control and flexibility
Parameterized Xmap Schemas/Queries.
Any subset of one or multiple Xmap Types can be returned by a Query with SQL optimisation based on elements requested
Output format can be defined for any Xmap member.
Supports SAX2 interfaces
Designed to run in server environment. Schema and Query are immutable and can be cached and accessed by multiple thread
Thread safe Xmap factory with caching and time stamp checking
Some hooks for J2EE (Security and JDBC resources
Support for non-database data (bean arrays)

This has to be one of the most spectacular contributions to the Open Source community in recent years. My company has been developing RIAs recently and when looking at Flex and Laszlo all we could think was "wouldn't it be great if there was an open source project that did the same thing!"
It's a wish come true. To the Laszlo executives and management, thank you for an incredible contribution and for taking such a bold and risky leap. If this project gains the right momentum from developers, it can become the de-facto standard for developing and deploying RIAs. Forget clumsy JSF and quirky web frameworks. Lazlo+Tomcat+Spring+Hibernate, the future of distributed, rich internet applications :)
The quality of the documentation alone deserves an award! It is definitely far beyond anything else I've seen in open source projects recently. Great demos and examples.
Thanks again, congratulations and much luck on your new corporate life!
Comments:
IMO, it is strategically dangerous to depend on the Flash Player as the sole rendering engine/client (I know it can potentially render to other client technologies, but it currently does not and I don't know of other client engines that can deliver the quality and features Flash has). Although it is widely deployed, Macromedia can change their mind on a moment's notice and limit its distribution to Flex licensees and/or paying customers. I know it doesn't seem likely now, but many things can happen in just a few years, when XAML and other RIA alternatives threaten their livelihood.
Many features of the platform depend on features of the Flash Player. For example, the newer Flash Players have very solid media delivery capabilities (e.g. Flash Video). It would be impossible for open source developers to create sophisticated new features when they don't control the client engine. Although what is there now seems "good enough" for most application requirements, who knows what we'll see in the next two years.
Suggestions:
As someone else mentioned, an OpenAMF transport should be a no brainer.
I'll look deeper into the RPC approach, but at first, it looks like it could benefit from additional flexibility/pluggability/plumbing with alternative back-ends frameworks (e.g. Spring). The current JavaRPC seems a little rigid and tightly coupled. -

As impressive as Laszlo work is, I think that Flash is only a temporary solution on a way to truly internet-integrated applications. Basically, there are two ways of interacting with outer world: either fully embrace it or treat it as a insecure and even hostile environment.
The traditional document-based HTML technology makes a clear separation between local computer and an outer network. Fully integrated applications are on the other end of spectrum, this is what Avalon promises.
Flash seems to be neither here nor there. Granted, I have not programmed for Flash (yet? I will surely try with Laszlo), so my thoughts are based mostly on Flash applications that I evaluated.
* Flash applications run in the browser window and assisted by browser code. OK, this may not be the biggest issue, browser window may be created without header and borders. But it is not the standard case now, so visually Flash applications do not look like native.
* Flash has its own widget style, so Flash apps stand out and do not blend with native apps.
* Despite that Flash was supposed to run within browser, its integration with browser does not seem to be great. How about hooks for common browser tasks like encoding, font size, color palette and background color, full screen mode, etc? Macromedia has separate Flash playeer versions for different browsers, why they did not bother to stick in some hooks proprietary for each browser? Or did they, but no one uses them?
* What about standard print/preview/pagination?
* What about standard help?
* What about cache/local storage management? How Flash apps can be stored locally, updated when changed, etc? There is no point to download the same 300K or even couple of megs of SWF each time I navigate to a Flash web page, but I do not have much control over it.
* What about fluid visual design and user-configurable font size? Currently Flash apps' fonts, colors, widget sizes cannot be configured neither from web browser nor from OS "Desktop preferences" settings. I would like to see at least one Flash app which allows to configure these settings. Where and how the settings are stored?
* Apparently, settings can be stored on the server only, because Flash does not have access to local directories and files. This makes Flash applications not as powerful as applets. They cannot be controlled separately from other web sites, so if a user erases all cookies, the Flash app settings are effectively gone. Contrary to Flash, local apps or Java applets can store their configuration and user data locally, and are not succeptible to manipulations with browser settings and cache cleanup.
* Flash does not have much of a windowing system or task management. Can I run two different Flash apps in one player window? And moving or resizing of windows is painfully slow.
* Either Flash keyboard support sucks big time, or developers do not bother to assign all needed keyboard mappings to the controls (if Flash has a notion of controls at all). Even Laszlo demos lack keyboard support, only pushbuttons and edit fields can be focused. I don't know about artists who create Flash apps, but I prefer to use good old keyboard whenever possible.
My feeling is that Flash cannot substitute a real windowing application. In that sense, even Java applets are better than Flash. Applets can have L&F of client OS and can store data on client system.
Web-start applications with SWT UI are even better, they can be easily installed, they blend with native applications and can access local resources. What they lack, though, is unpredictability of internet; they should be loaded as one piece, and the whole process of "loading" is boring. They need JRE too.
My dream of RIA applicaiton is something that:
* visually blends with client system
* does not require "loading"
* is not solidified after it is downloaded
* has access to local resources, and allows to easily change security settings
Based on what I know, Avalon apps should be closer than any other to my ideal system. If I would be able to download dynamic XAML from the internet while browsing and visually interpret it as application windows and controls, I would be completely happy.
What I like about Laszlo approach to Flash though, is datasets. The source code for Amazon front end shows how easy data management should be:
* ask Amazon for XML data
* show needed elements using XPath
This is really, really, really neat.
On the other hand, I do not like to program in XML. XML is for data, not for programs. Apparently, Laszlo guys started from markup and added code later, but it does not look pretty. Microsoft approach with code-behind classes is nicer. One can blend code and data in XAML or in .Net code, depending on their likes.
As of now, Avalon looks better than other RIA solutions. Flash will die very fast after Avalon/XAML applications rolled out. The question is: what should we do in the meantime? -

Just one more thing: SWT Web Start or even Java applets can work with local devices. Flash application apparently cannot. Thus, Flash cannot be used to create a full-blown client application, it is only a visual front end. If I need to interact with printer or scanner, I would have to write a separate app and interact with it over HTTP/FTP/whatever. This makes things more complicated than I would like them to be. -

Michael, you bring up some valid points here; I personally also do not like the idea of programming in XML; it is not too convenient to say the least.
Look at IAB Studio from www.worcsnet.com; basically, it is a somewhat interesting tool for RAD development of RIA apps; the guys use JS controls on the client side instead of Flash and some J2EE framework on the server side; One interesting feature is that they have in-browser Page designers, which is kinda kool - they are also written in JS -) There is a demo application at www.iabstudio.com;
Flash demo's looked better from the design point of view for me; but otherwise IAB Studio does the same thing; have a look.
