LOTD #2: Phobos - MVC framework based on JavaScript
Phobos is a
lightweight, scripting-friendly, web application environment running on
the Java platform. It provides a complete MVC framework where
Controller is a JavaScript class, View is an Embedded JavaScript (EJS)
file and Model is typically a mix of Java and JavaScript.
The tech tip explains how Phobos and jMaki can be used
to create a simple Ajax-enabled application using NetBeans tooling and GlassFish for
deployment.
All previous entries in this series are archived at LOTD.

GlassFish and jMaki @ RailsConf Today
 |
I was originally planning to give my first talk at Rails
Conf on "Rails
powered by GlassFish and jMaki". But I cannot travel for
personal reasons and instead Craig
McClanahan, who is an excellent speaker, has graciously
agreed to speak. Craig has been involved with Rails, GlassFish and
jMaki
for a long time so feel free to poke hime at the talk, in the exhibit
hall and afterwards. |
Thanks Craig for the wishes! I had a great time @ RailsConf 2007 (here and here) but life is about priorities :)
More information about support for Dynamic Languages and their Frameworks on GlassFish can be found on glassfish-scripting.dev.java.net.

JavaOne 2008 is finally over ... 9th consecutive one for me and
extremely busy as always!
- John talked about GlassFish related announcements. Some important names/renames/announcements:
- "Sun Java System Application Server" is now "Sun GlassFish Enterprise Server"
- GlassFish Enterprise Server Unlimited (page coming soon) - Deploy as much as GlassFish Enterprise Server
- GlassFish Initiative for Technology Partners
- GlassFish ESB
- Sun GlassFish Communications Server is the product version of SailFin
- GlassFish v3 Technology Preview 2 was released with NetBeans and Eclipse support
- Other details in John's blog
- JavaU Bonus
Evening Course on GlassFish Application Server - Shreedhar
and I delivered a Bonus
Evening Course on GlassFish in JavaU. We talked about
GlassFish in depth - general overview, concepts, Metro Web services,
dynamic
languages support, high availability/clustering and lots of
other details. The slides for the course are available here.
Read more details in Shreedhar's Writeup. - GlassFish
Unconference - Vivek
and I led the "Scripting in GlassFish" session @ GlassFish
Unconference
and then I led the "Web services" session. It was very free-form forum,
basically answering questions/clarifications from the participants and
seeking feedback on our direction.
It was great to know that people love Metro support in NetBeans and are some are using the IDE for that reason only. - Scripting in
GlassFish (BOF 5111) - Vivek
and I presented on "Scripting in GlassFish"and explained the support
for different dynamic languages such as Ruby/Rails, Groovy/Grails,
Python/Django on GlassFish. This preso showed bunch of demos including
GlassFish v3 gem installation and deployment (screencast coming soon),
GlassFish v3 Update Center, Rails Development/Deployment options,
Groovy/Grails and Python/Django deployment. The slides are available here.
You can find the latest information about support for different dynamic languages on glassfish-scripting.dev.java.net. - Lab 4530:
Building Rich Web Applications with jMaki - Doris
and I delivered Lab
4530: Building Rich Web Applications with jMaki. If you could
not attend JavaOne, then you can follow the instructions
at your own pace and download
the entire lab.
The complete material for all JavaOne 2008 Hands-on-Labs is available here. The material is pretty comprehensive and of high quality. I highly recommend refering to this material for sharpening your skills. - Tic Tac Tac @
General Session Keynote - I
presented "Tic Tac Toe Demo" at General Session Keynote on Tuesday
afternoon. This demo was a multi-player game developed in multiple
scripting languages (Ruby, Groovy and Python) and their associated Web
frameworks (Rails, Grails and Django) and all deployed on GlassFish v3
TP2. The main idea was to showcase multi-lingual support on GlassFish
v3 and still able to use GlassFish features such as GlassFish Comet
to push the events to browser. The entire source code for the demo will
be released shortly and I'll announce the availability.
You can watch the entire video here (starting at approx 1:10 into it). Hope you enjoy the War Games-esque look-and-feel. It was a keynote demo Hat-trick for me (jMaki/Phobos @ 2007, .NET Interoperability @ 2006. I'm happy to be labeled as "GlassFish Guy" :)
I took lots of pictures through out the event and posted them regularly. They are all available here. A consolidated album is inlined:

Ajax World East 2008 - Day 2 Report
I delivered my Maki
as an Ajax Mashup Framework talk and the slides are available
here.
Lots of attendees came by afterwards and told me that they enjoyed the
demo. The talk showed how jMaki
Webtop provides a lightweight mashup framework that runs in
the browser. Here is a pictorial representation of the demo shown:
jMaki Webtop is basically a jMaki widget that can be embedded in a JSP
or PHP page. This widget provides the framework for managing widgets
and users, ability to persist the Webtop on client-side using Google
Gears or server-side using backend database, layouts and other
functionality. In JSP case, the widget uses JPA for performing all the
CRUD operations with the back-end MySQL database. The resulting WAR
file is deployed on GlassFish
(can be any other Servlet container as well). If you are interested in
a Java version of Webtop then the recommended path is:
- Create services & widgets using NetBeans
- Deploy them on GlassFish
- jMaki webtop for widget deployment & customization
I attended few more talks and took notes in some of them to share:
- Can we fix the Web ?
- Accelerate Ajax development with Appcelerator
- REST & Ajax Reconciled
- Understanding the Top Web 2.0 Attack Vectors
- Building Web 2.0 Applications with Project Zero
- OpenAjax Widgets & Gadgets
Can we fix the Web ?
This was an early morning talk (7:30am) and I reached few minutes late. But it was basically talking about JavaScript vulnerabilities such as
- Script injection
- No difference between user & guest scripts
- Scripts exempt from same-origin policy
- No modularity (global access to everything on the page)
Doug recommended 3-step plan to fix the Web:
- Safe JavaScript subset
- JSLint.com provides a safe subset of JavaScript that removes all features that are unsafe or suspect such as no global vars or functions
- Google Caja & Cajita provide a similar subet but they use transformation instead of validation
- Minor browser improvements
- Scripts are exempt from same-origin policy. This allows a dynamic <script> tag to make a GET request from a server. Instead use JSONRequest (part of json.org).
- ES4 (the upcoming JavaScript standard) is not good enough because it maintains backwards compatibility and adds complexity.
- Major browser improvements
- Replace JavaScript & DOM in browsers. The approach is to start with JSLint and add safe features as required.
- The Object Capability System (where objects are given explicit access to be used) needs to be enforced to make it secure.
The second talk was on Accelerate Ajax development with Appcelerator by Appcelerator CEO.
The talk started with a "not too long back" introduction of the technology space. Well, it started with 1991 and the timeline (and associated technology advances in that year) kept shuffling 1995, 1989, 2001 .... and so on. Jeff talked about how/why Tim Berners Lee invented WWW and covered a myriad of terms after that including but not limited to - Web 1.0, Netscape, Mosaic, marc Andreeeseen (sp?), Java, java Web Start, Applets, W3C, CGI, J2EE, JCP, C#, JBoss, SOA, JavaFX, Silverlight, AIR and many others. For a 50 minute talk, that was quite a long introduction.
After that introduction, he word "Ajax" was mentioned almost 30 minutes (8:51am to be precise) in the talk. And then the word "Appcelerator" was mentioned at 9:06am. Finally, I realized that I'm in the right talk ;)
Appcelerator like to pitch themselves as RIA + SOA company and allows true decoupling of the rich client from it's services. Their services is very similar to jMaki but they use event handling + Ajax + DHTML to achieve it. They also run on Ruby, PHP, Java and other languages.
All in all, it was a good walk through the memory lane!
The next one was REST & Ajax Reconciled.
The talk explained the basic concepts of REST - Resource, URI, Representation, URL & Methods (GET, PUT, POST & DELETE). It also explained the idempotency and safety of each method type. Overall a good decent introduction.
Then it explained the limitations with current web-based forms:
- The URIs in the action attribute cannot be changed dynamically
- Most browsers recognize only GET/POST methods
- Limited ecodings - for example generating JSON encoding requires extra work.
- Does it have resource-based approach ?
- Acknowledges existing of representation ?
- need multiple of them
- Solid engineering & community support ?
- Apache Cocoon - based on XML pipelines & URL patterns, powerful but steep learning curve
- RESTlet - Like Servlet for REST, good for existing model
- Apache Sling - Based on JCR with server-side scripting support
The speaker recommended Apache Sling with µjax for all REST + Ajax needs. But I'd strongly encourage you to have a look at Jersey. The JSON representation generated out of Jersey can now be directly consumed by jMaki as described here - a true combination of REST & Ajax :)
And then the last talk where I took notes is Understanding the Top Web 2.0 Attack Vectors. I'll provides notes from the last 5 slides of the talk which essentially captured the essence. These slides talked about fundamental issues with Ajax and described concerns and possible attacks in each issue. I'll need to understand some of these attacks better myself but at least I have a list to begin with :)
Here you go:
- Client-side
- Concerns
- Transparency
- Cross-domain communication
- Exposed business logic (View Source)
- Local & Offline data storage
- Attacks
- Cross-site scripting, DNS Rebinding
- Business logic bypass
- Variable tampering
- Protocol hijacking
- Function clobbering
- JavaScript hijacking
- Protocols
- Concerns - new protocols on top of HTTP
- SOAP
- XML-RPC
- REST
- Attacks
- Traditional
- Man-in-the-middle
- Spoofing
- Recursive Payloads
- Schema Poisoning
- Information Sources
- Concerns
- Integrity
- Transient
- Diverse (RSS, Blogs, Email, ...)
- Attacks
- Untrusted content
- Poisoned Cache (HTTP Response Splitting Vulnerability)
- DNS Issues
- Information Structure
- Concerns - Variations of data structure
- RSS
- Atom
- JSON
- Serialized data
- Attacks
- Malicious injection
- Parser implementations
- Server-side Issues
- Concerns
- Architecture Weaknesses
- Multiple languages & implementations
- Increase & fragmented attack surfaces
- Unknown request origin
- Authorization & Authentication in complex environment
- Attacks
- Traditional
- Information disclosure, Logical attributes, Denial-of-service
- Command Injection
- LDAP, SQL, XPath etc.
OpenAjax Alliance talk about Gadgets & Widgets was nice. The alliance is working on creating standards for widget metadata, communication across widgets and other similar tasks. The goal is to enable successful adoption of open and interoperable Ajax-based Web technologies.
Dave Ferraiolo (from OpenAjax) particularly expressed thanks to jMaki for deriving the first set of Open Ajax Data Model specs from jMaki data models.
That's it!

Ajax World East 2008 - Day 1 Report
Ajax World East 2008 started earlier today.
I delievered my "Web 2.0 Application development using jMaki" and the
slides are available here.
There were several demos shown in the talk (using NetBeans and GlassFish)
and they are all accessible at the links mentiond below:
Anyway I attended 3 more talks today and took notes to share:
- Picking the Right Technology for Enterprise Rich Internet Applications
- Performance Tuning your Ajax Applications
- Performance Paradigm of a Mashup World
The first talk I attended was: Picking the Right Technology for Enterprise Rich Internet Applications. I got little late and the session was packed with attendees standing way outside the room so I joined them.
- Seamless deployment on client
- High penetration of runtime
- Web browser independence
- Fast client/server communication protocol
- Robust security
| Pros of Ajax | Cons of Ajax |
| No deployment required | Ajax apps are browser depdendent |
| 100+ Frameworks | 100+ Frameworks |
| Open Source, no need to purchase software license | Expensive due to long cycle, skilled developers demand top rate |
| JavaScript is an interpreted language, entire source code can be viewed using "View Source" | |
| Network communication speed is not optimizedf for Ajax requests |
And then basically it talked about the three technologies and their pros & cons are well captured in the slides.
The second session I attended was Performance Tuning your Ajax Applications. This was an interesting session and I learned a few tricks. Interstingly we have implemented quite a few of these performance enhancements in jMaki already.
Improving the performance of Ajax applications require tuning the following parameters:
- Number of requests
- Reduce number of JavaScript files that are loaded. This is the most important since each request to the backend adds extra cost. Even when the scripts are cached, the browser still makes a request (unless Since-Modified header is set correctly).
- Typical approaches are to concatenate the files at dev time or at runtime based upon request.
- Dev time approaches
- Ant - concat all JS files using <concat> task
- Dojo - Run Rhino over all provide/requires and then concatenate the files
- Command-line
- Run time approaches - Concatenation happens depending upon the request. Cons are:
- Server-side dependent
- Makes it harder to distribute code
- Server is loaded as concatenation happens on server (mitigated with caching)
- Works for <15 JS files
- Does not track dependency
- Size of requests
- Remove white spaces and comments (Packer, Dojo, YCompresser, SafeCompress, ShrinkSafe are some of the tools)
- Shorten the variable names
- Gzip the code
- Semicolon is optional but needed if you remove EOL (careful when compressing the code)
- Drastically reduces the file size (e.g. Apache XAP reduced the file size from 330 kb to 70 kb)
- Lots of gzip tools
- Need to put appropriate headers so that browsers recognize gzipped content
- Coding Style
- Single line "if" and "for" do not need "{ }"
- Combine var declarations into a single var such as var x=1, y = 2;
- Use JavaScript style object
- Time of requests
- Time of initial code completion
- Minimize the time that is executed @ start up
- Bring the data once the initial page is loaded
- Show images telling users that something is going on
- Distracts user from the time it's taking
- Other tips
- Don't write your own parser - use the native parsers
- "If" statement optimization
- Use the native facilities like getElementById() or getElementByTagName()
- Consider different approaches of DOM creation
- Tail Recursion
- Setting the value in innerHTML
- Consider JSON over DOM for object graph traversal - JSON could be much faster
My third talk of the day was Performance Paradigm of a Mashup World.
This talk given by Vice President of Webmetrics and laid a special emphasis on "Collaborative Monitoring" for performance measuring any mashup. This process involves not only monitoring your own application, but also setting up agents that measure performance with other services being invoked in the mashup, their further partners and so on. It also talked about a layered approach of using:
- Standard monitoring - HTML page load time, DNS request processing time, etc.
- Pixel Mapping monitoring - required mainly for GUI intensive application
- Web services monitoring - Used for partner monitoring
- Know your apps
- Learn where the points are in your ecosystem
- Measure your perspective
- Monitor your APIs
- Collaborate within your organization
- Collaborate with your partners & customers

jMaki on Rails - Reloaded for NetBeans 6.1 beta & Rails 2.0
NetBeans
6.1 Beta was released last week. Amongst the many
improvements, one of them is the bundled JRuby 1.1 RC2 and Rails 2.0.2. The jMaki plugin used
to work fine with Rails 1.2.3 but need to be updated because of changed
file name extensions for the default generated views (".rhtml.erb"
instead of ".rhtml"). With this release of NetBeans, jMaki plugin has
been updated to work in this configuration as well.
This blog provide detailed steps to install jMaki plugin, create a
simple Rails 2.0 application using NetBeans IDE and update the
generated scaffold to use a Yahoo Data Table widget for displaying the
data. It is an update to screencast
#web8, lets get started!
- Install the jMaki plugin - In NetBeans IDE, go to "Tools",
"Plugins". Select "jMaki Ajax support" and click on "Install" button as
shown in the following figure:
Follow the instructions to install the plugin. The IDE is restarted after a successful install. - Create a new Rails project
- Create a new Rails project by selecting "File", "New
Project..." and selecting "Ruby" and "Ruby on Rails Application". Take
all the defaults as shown below:
and click on "Next >". - Choose "Specify Database Information Directly" and
specify the database configuration information as shown below:
and click on "Finish". You need to make sure MySQL server is running. - Generate Scaffold and Database structures
- Right-click on the newly created project, select
"Generate..." and enter the values as shown below:
and click on "OK". This creates a scaffold and model that would allow us to perform CRUD operations on Title, Author, ISBN and Description for a Book. - Create the datbase by invoking db:create target.
This is done by right-selecting the project, select "Run Rake Task",
"db" and then "create" as shown below:
- Create the database tables by running "db:migrate" using the similar steps described above - "Run Rake Task", "db", "migrate".
- Add and Configure jMaki widget
- In the project, expand "Views", "books" and double-click
on "index.rtml.erb" to edit it. This page is used to display all the
books from the database table in an HTML table. It also shows links to
perform CRUD operations on each book item. From the jMaki
Yahoo palette, drag-and-drop a "Yahoo Data Table" right after
"</table>" tag. The generated fragment looks like:
- The default generated code fragment shows 4 columns in
the table. Lets add a new column to display the CRUD operations link.
Add the following fragment:
{ :actions => 'Action', :id => 'actions' }
right after
{ :label => 'Description', :id => 'description'}
You also need to add a comma "," after the Descrption column fragment. The updated code looks like:
- Add the following Ruby fragment right before "<%=
jmaki_widget" generated code:
<%
@rows_data = []
for book in @books
@rows_data << { :id => book.id,
:title => book.title,
:author => book.author,
:isbn => book.isbn,
:description => book.description,
:actions => link_to('Show', book) + ' ' + link_to('Edit', edit_book_path(book)) + ' ' + link_to('Destroy', book, :confirm => 'Are you sure?', :method => :delete)
}
end
%>
This fragment creates a JSON array, @row_data, in the format expected by Yahoo Data Table widget, after retrieving the values from the database. - Finally, instead of reading the static values for
columns, use the newly created "@row_data" to populate the values. The
code with all the changes looks like as shown below:
- Run the project
- The scaffold is now accessible at
http://localhost:3000/books. This page in the browser looks like:
- After adding couple of entries, the page looks like:
