  • Curiosity’s Descent to Mars in HD [Video]

    - by Jason Fitzpatrick
    Thanks to the Mars Descent Imager (MARDI) mounted on the fore-port side of Curiosity we’re treated to a high-resolution video of Curiosity’s descent to Mars. The video from MARDI, combined with the video editing of YouTube user DLFitch, yields the above video. He writes: This is a full-resolution version of the NASA Curiosity rover descent to Mars, taken by the MARDI descent imager. As of August 20, all but a dozen 1600×1200 frames have been uploaded from the rover, and those missing were interpolated using thumbnail data. The result was applied a heavy noise reduction, color balance, and sharpening for best visibility. The video plays at 15fps, or 3x realtime. The heat shield impacts in the lower left frame at 0:21, and is shown enlarged at the end of the video. Image source.

  • Earth’s Radiation Belt Sounds like Whale Song [Video]

    - by Jason Fitzpatrick
    The radio frequencies of Earth’s radiation belt have uncanny resemblance to a sort of whale/bird song remix. Check out this video to learn more about NASA’s efforts to explore the belts and listen to the Earth’s song. When we hear the “song” of the Earth, exactly what are we hearing? Science@NASA explains: Chorus is an electromagnetic phenomenon caused by plasma waves in Earth’s radiation belts. For years, ham radio operators on Earth have been listening to them from afar. Now, NASA’s twin Radiation Belt Storm Probes are traveling through the region of space where chorus actually comes from–and the recordings are out of this world. “This is what the radiation belts would sound like to a human being if we had radio antennas for ears,” says Kletzing, whose team at the University of Iowa built the “EMFISIS” (Electric and Magnetic Field Instrument Suite and Integrated Science) receiver used to pick up the signals. He’s careful to point out that these are not acoustic waves of the kind that travel through the air of our planet. Chorus is made of radio waves that oscillate at acoustic frequencies, between 0 and 10 kHz. The magnetic search coil antennas of the Radiation Belt Storm Probes are designed to detect these kinds of waves.

  • Open Data, Government and Transparency

    - by Tori Wieldt
    A new track at TDC (The Developer's Conference in Sao Paulo, Brazil) is titled Open Data. It deals with open data, government and transparency. Saturday will be a "transparency hacker day" where developers are invited to create applications using open data from the Brazilian government.  Alexandre Gomes, co-lead of the track, says "I want to inspire developers to become "Civic hackers:" developers who create apps to make society better." It is a chance for developers to do well and do good. There are many opportunities for developers, including monitoring government expenditures and getting citizens involved via social networks. The open data movement is growing worldwide. One initiative, the Open Government Partnership, is working to make government data easier to find and access. Making this data easily available means that with the right applications, it will be easier for people to make decisions and suggestions about government policies based on detailed information. Last April, the Open Government Partnership held its annual meeting in Brasilia, the capitol of Brazil. It was a great success showcasing the innovative work being done in open data by governments, civil societies and individuals around the world. For example, Bulgaria now publishes daily data on budget spending for all public institutions. Alexandre Gomes Explains Open Data At TDC, the Open Data track will include a presentation of examples of successful open data projects, an introduction to the semantic web, how to handle big data sets, techniques of data visualization, and how to design APIs.The other track lead is Christian Moryah Miranda, a systems analyst for the Brazilian Government's Ministry of Planning. "The Brazilian government wholeheartedly supports this effort. In order to make our data available to the public, it forces us to be more consistent with our data across ministries, and that's a good step forward for us," he said. He explained the government knows they cannot achieve everything they would like without help from the public. "It is not the government versus the people, rather citizens are partners with the government, and together we can achieve great things!" Miranda exclaimed. Saturday at TDC will be a "transparency hacker day" where developers will be invited to create applications using open data from the Brazilian government. Attendees are invited to pitch their ideas, work in small groups, and present their project at the end of the conference. "For example," Gomes said, "the Brazilian government just released the salaries of all government employees and I can't wait to see what developers can do with that."

  • JavaScript: this

    - by bdukes
    JavaScript is a language steeped in juxtaposition.  It was made to “look like Java,” yet is dynamic and classless.  From this origin, we get the new operator and the this keyword.  You are probably used to this referring to the current instance of a class, so what could it mean in a language without classes? In JavaScript, this refers to the object off of which a function is referenced when it is invoked (unless it is invoked via call or apply). What this means is that this is not bound to your function, and can change depending on how your function is invoked. It also means that this changes when declaring a function inside another function (i.e. each function has its own this), such as when writing a callback. Let's see some of this in action: var obj = { count: 0, increment: function () { this.count += 1; }, logAfterTimeout = function () { setTimeout(function () { console.log(this.count); }, 1); } }; obj.increment(); console.log(obj.count); // 1 var increment = obj.increment; window.count = 'global count value: '; increment(); console.log(obj.count); // 1 console.log(window.count); // global count value: 1 var newObj = {count:50}; increment.call(newObj); console.log(newObj.count); // 51 obj.logAfterTimeout();// global count value: 1 obj.logAfterTimeout = function () { var proxiedFunction = $.proxy(function () { console.log(this.count); }, this); setTimeout(proxiedFunction, 1); }; obj.logAfterTimeout(); // 1 obj.logAfterTimeout = function () { var that = this; setTimeout(function () { console.log(that.count); }, 1); }; obj.logAfterTimeout(); // 1 The last couple of examples here demonstrate some methods for making sure you get the values you expect.  The first time logAfterTimeout is redefined, we use jQuery.proxy to create a new function which has its this permanently set to the passed in value (in this case, the current this).  The second time logAfterTimeout is redefined, we save the value of this in a variable (named that in this case, also often named self) and use the new variable in place of this. Now, all of this is to clarify what’s going on when you use this.  However, it’s pretty easy to avoid using this altogether in your code (especially in the way I’ve demonstrated above).  Instead of using this.count all over the place, it would have been much easier if I’d made count a variable instead of a property, and then I wouldn’t have to use this to refer to it.  var obj = (function () { var count = 0; return { increment: function () { count += 1; }, logAfterTimeout = function () { setTimeout(function () { console.log(count); }, 1); }, getCount: function () { return count; } }; }()); If you’re writing your code in this way, the main place you’ll run into issues with this is when handling DOM events (where this is the element on which the event occurred).  In that case, just be careful when using a callback within that event handler, that you’re not expecting this to still refer to the element (and use proxy or that/self if you need to refer to it). Finally, as demonstrated in the example, you can use call or apply on a function to set its this value.  This isn’t often needed, but you may also want to know that you can use apply to pass in an array of arguments to a function (e.g. console.log.apply(console, [1, 2, 3, 4])).

  • Obama’s win and the geeky stuff behind his success

    - by Gopinath
    Mr. Obama is elected as President of United States for the second term with a great majority. Here are few geeky bytes associated with Mr.Obama’s success and the world records he set up Obama Creates New Records on Twitter and Facebook – Just after winning the race for president, Barak Obama setup world records on Twitter & Facebook. His tweet “Four more years” re-tweeted more than 770K times and his Facebook post received 3.8 million likes. Twitter Kills the Fail Whale, One Tweet at a Time – Twitter handled insane user loads with millions of tweets related to election and proved that it’s platform is now more robust than ever. In a post on the company’s engineering blog, Twitter said people sent 31 million election-related tweets on Tuesday alone. From 8:11 p.m. to 9:11 p.m. P.S.T., Twitter processed an average 9,965 tweets per second, with a one-second peak of 15,107 tweets per second at 8:20 p.m., the company said. Obama’s win a big vindication for Nate Silver, king of the quants – Nate Silver, a statistician and blogger was spot on in predicting Obama’s win many weeks. He did not depend on astrology or surveys to predict Obama’s success. He used big data and statistical analysis to project votes. CNET says “Despite some incredulous political pundits, the FiveThirtyEight statistician appears to have correctly predicted the winner in all 50 states in the presidential election” Inside the Secret World of the Data Crunchers Who Helped Obama Win – Team Obama used big data and analytical systems to win the elections!! Barack Obama Goes On Reddit For Last Campaign Stop Of Political Career – Reditt is getting a lot of Obama’s attention these days.

  • Friends Don’t Let Friends Play with Portal Guns [Video]

    - by Jason Fitzpatrick
    Many Portal fan films are sci-fi stories in their own right; this humorous video is simply focused on what happens when three guys get their hands on a portal gun. Jason Craft, the video’s director, explains: My interpretation of what a real POrtal gun would be like if one existed. Based on the video game, POrtal. I tried to match the game as close as possible. This was the most challenging project I have ever undertaken, consisting of 3D tracking, seamless camera cuts and 3D camera projection. ENJOY!

  • Google Chrome OS

    - by Piet
    It’s about time someone took this initiative: Google Chrome OS I especially like the following: Speed, simplicity and security are the key aspects of Google Chrome OS. We’re designing the OS to be fast and lightweight, to start up and get you onto the web in a few seconds. The user interface is minimal to stay out of your way, and most of the user experience takes place on the web. And as we did for the Google Chrome browser, we are going back to the basics and completely redesigning the underlying security architecture of the OS so that users don’t have to deal with viruses, malware and security updates. It should just work. I recently had the ‘pleasure’ witnessing several 60+ yr old friends and family (all respect for everyone in their 2nd or 3rd youth) buying their first pc, taking their first steps using a pc and the net. Have you ever seen the gazillions of little ‘useful’ tools that are installed on a new standard Vista pc or laptop ? This is like learning to drive a new car and being placed in an airplane cockpit. And all the messages one gets about virus/security checks, fingerprint nog being enrolled, trial period expiring (because half those really useful tools come with a trial period), … If I was in their shoes, being confronted with this as a total newbie, I guess I’d just give up pretty soon. As a matter of fact, I actually gave up on Vista on my work-laptop, it was driving me crazy. Thank god I was allowed to install XP. I’m a Linux user at home, and Vista was such a frustrating experience that Windows XP actually felt like breath of fresh air. And what are those people using? Email, browsing…. and maybe writing a little letter now and then or storing their photo’s if they have a digital camera. Actually (side note), I get the impression that hearing about facebook is a major motivator for the digital newbies to finally take the plunge, buy a pc and get on-line. And OK, we’ve seen initiatives like this before, but Google is a brand everyone knows… unlike Ubuntu, Debain or Mandriva. Google = God. If I was Microsoft I’d be wetting my pants knowing Google was about to release their own OS, without a doubt fully optimized to use their own on-line office suit. On the other hand, the old adage ‘no one ever got fired for choosing Microsoft’ still holds a lot of truth. I hope I’ll be able to give it a big thumbs up if a would-be pc-user asks me what kind of pc/OS they should go for in the near future. On the other hand, if I’d do that, I’m pretty sure a couple of weeks later I’d get a call asking how to install this game or photo editing tool they got from one of their Windows using friends… or that nifty photo-printer they just bought. But then, I also get those questions now from newbie Windows users. It takes a couple of years before Newbie pc users understand that some things just don’t work and aren’t worth the time trying to fix them. I’d just wish they’d go back to the shop when something doesn’t work. You also don’t let you mechanic friend try to fix a problem with your brand new car. But that’s another story… Wait and see…

  • Update on ASP.NET MVC 3 RC2 (and a workaround for a bug in it)

    - by ScottGu
    Last week we published the RC2 build of ASP.NET MVC 3.  I blogged a bunch of details about it here. One of the reasons we publish release candidates is to help find those last “hard to find” bugs. So far we haven’t seen many issues reported with the RC2 release (which is good) - although we have seen a few reports of a metadata caching bug that manifests itself in at least two scenarios: Nullable parameters in action methods have problems: When you have a controller action method with a nullable parameter (like int? – or a complex type that has a nullable sub-property), the nullable parameter might always end up being null - even when the request contains a valid value for the parameter. [AllowHtml] doesn’t allow HTML in model binding: When you decorate a model property with an [AllowHtml] attribute (to turn off HTML injection protection), the model binding still fails when HTML content is posted to it. Both of these issues are caused by an over-eager caching optimization we introduced very late in the RC2 milestone.  This issue will be fixed for the final ASP.NET MVC 3 release.  Below is a workaround step you can implement to fix it today. Workaround You Can Use Today You can fix the above issues with the current ASP.NT MVC 3 RC2 release by adding one line of code to the Application_Start() event handler within the Global.asax class of your application: The above code sets the ModelMetaDataProviders.Current property to use the DataAnnotationsModelMetadataProvider.  This causes ASP.NET MVC 3 to use a meta-data provider implementation that doesn’t have the more aggressive caching logic we introduced late in the RC2 release, and prevents the caching issues that cause the above issues to occur.  You don’t need to change any other code within your application.  Once you make this change the above issues are fixed.  You won’t need to have this line of code within your applications once the final ASP.NET MVC 3 release ships (although keeping it in also won’t cause any problems). Hope this helps – and please keep any reports of issues coming our way, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links.

  • Clean Code: A Handbook of Agile Software Craftsmanship – book review

    - by DigiMortal
       Writing code that is easy read and test is not something that is easy to achieve. Unfortunately there are still way too much programming students who write awful spaghetti after graduating. But there is one really good book that helps you raise your code to new level – your code will be also communication tool for you and your fellow programmers. “Clean Code: A Handbook of Agile Software Craftsmanship” by Robert C. Martin is excellent book that helps you start writing the easily readable code. Of course, you are the one who has to learn and practice but using this book you have very good guide that keeps you going to right direction. You can start writing better code while you read this book and you can do it right in your current projects – you don’t have to create new guestbook or some other simple application to start practicing. Take the project you are working on and start making it better! My special thanks to Robert C. Martin I want to say my special thanks to Robert C. Martin for this book. There are many books that teach you different stuff and usually you have markable learning curve to go before you start getting results. There are many books that show you the direction to go and then leave you alone figuring out how to achieve all that stuff you just read about. Clean Code gives you a lot more – the mental tools to use so you can go your way to clean code being sure you will be soon there. I am reading books as much as I have time for it. Clean Code is top-level book for developers who have to write working code. Before anything else take Clean Code and read it. You will never regret your decision. I promise. Fragment of editorial review “Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way. What kind of work will you be doing? You’ll be reading code—lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly, you will be challenged to reassess your professional values and your commitment to your craft. Readers will come away from this book understanding How to tell the difference between good and bad code How to write good code and how to transform bad code into good code How to create good names, good functions, good objects, and good classes How to format code for maximum readability How to implement complete error handling without obscuring code logic How to unit test and practice test-driven development This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.” Table of contents Clean code Meaningful names Functions Comments Formatting Objects and data structures Error handling Boundaries Unit tests Classes Systems Emergence Concurrency Successive refinement JUnit internals Refactoring SerialDate Smells and heuristics A Concurrency II org.jfree.date.SerialDate Cross references of heuristics Epilogue Index

    Below is IDC’s Darren Bibby report on ‘The Partner Perspective from Oracle OpenWorld 2012’. If you missed the 2012 edition, I trust this will give you the willingness to attend next year one! October 26, 2012 I attended my fourth Oracle OpenWorld earlier in October. I always go in with the lens of, "What's in it for partners this year?" Although it's primarily thought of as a customer event - and yes, the bulk of the almost 50,000 attendees are customers - this year's conference was clearly the largest and most important partner event Oracle has ever run. Oracle PartnerNetwork (OPN) Exchange There were more partner attendees than ever, with Oracle citing somewhere around 5000. But the format for partners this year was different. And it was better. Traditionally, Oracle hosts a one-day only Partner Forum on the Sunday before the customer-focused conference begins. This year, the partner content still began on the Sunday, but the worldwide alliances and channels group created an exclusive track throughout the week, just for partners. It featured content specifically targeted towards partners, and was anchored at a nearby hotel. This was a great move for Oracle. The Oracle PartnerNetwork (OPN) team has been in a tricky position for years in that they have enough partners that they need a landmark event in the year, but perhaps not enough to justify a separate, worldwide, large, partner-only event. Coinciding a four day event with Oracle OpenWorld, where anybody who's anybody in the Oracle world attends anyway, is a good solution. The channels leadership team can build from this success for an even better conference next year. It's expected that they will follow a similar strategy. Cloud Announcements for Partners As for the content, it was primarily about the Cloud. For customers, for VARs, for ISVs, for everyone. There were five key Cloud related announcements for partners at the event: Cloud Builder Specialization. This is one of the first broader Specializations that isn't focused on one unique product. It is a designation for partners that offer design and implementation services for private cloud solutions. As such, it will surely be something that nearly every partner will consider, and many will pursue. New Specializations for Cloud Services. Unlike the broad, almost "strategy-level" Specialization above, there are a group of new product-based "merit badges" for many of the new Cloud offerings. Think about a Specialization for the Cloud version of HCM, for instance. Each of these particular specializations will also have Rapid Start implementation methodologies that allow a partner to offer a fixed scope and fixed price bid to customers. Based on the learnings from Oracle Consulting, this means a partner might be able to deliver Cloud HCM in six weeks for a fixed price. In the end, this means more consistent experiences for Oracle customers. Cloud Resale Program. For those partners who achieve one of these Cloud Specializations, it will mean they can actually resell the subscription-based Cloud product. This is important because it has been somewhat of a rarity in the emerging Cloud channel for partners to be able to "take the paper", take the revenue, do the billing, be first line of support etc. This is an important step for Oracle and one the partners will be happy to see. Cloud Referral Program. For those partners who are not as engaged with these specific Cloud products that the Specializations revolve around, there is a new referral program that provides an incentive to recommend Oracle Cloud products. This one-two punch of referral and resale programs is similar in many ways to other vendors who allow more committed partners to resell, while more casual partners can collect fees. It's the model that seems to work. The key to allow a company to resell a subscription product - something that is inherently delivered directly between the vendor and customer - is trust. Achieving a specialization is a good bar to have to meet. Platform as a Service for ISVs. Leveraging some of the overall announcements made by CEO Larry Ellison around a cloud version of its famous database, Oracle also outlined a new ability for ISVs to build cloud services on its new PaaS offering. Details were less available for this announcement, though it's an expected and fitting play for ISVs comfortable with Oracle technology who can now more easily build out cloud applications. There wasn't much talk of an app store to go along with this, but surely it's in the works. Specializations And "The Gap" Coming back to Specializations, Oracle PartnerNetwork (OPN) has 4600 partners worldwide that hold 20,000 Specializations. These are impressive numbers just three years into the new OPN framework. The actual number of Specializations has also grown significantly, up to 111 today and soon around 125 or so with the new Cloud designations. Oracle may need to look at grouping some of these and creating higher level, broader designations that partners could achieve by earning several Specializations in that group. At 125 and growing, this is a lot. On the top of the pyramid, Hitachi Ltd. successfully became the eleventh partner to make it to the highly prestigious Diamond level. Partner programs partially exist in order to recognize capable partners. And it's more than abundantly clear that the Diamond level does this. But I think Oracle has a gap. Specializations show capability in a very specific product area, and all sizes of partners can achieve these. The next level at which to show a level of expertise is the Advanced Specialization. However, this is a massive step up from the regular Specialization. The advanced level requires 50 people to have certification in that particular product area. Most other industry programs have similar higher level statuses, but none are even close to that number. Whereas a customer who sees an Oracle partner with an advanced specialization can be very sure of capability, there is a gap in that there are hundreds or even thousands of 20-50 person solution providers who are top notch in their area of expertise. They will never get to Advanced due to numbers alone. These boutique partners don't really have a way of showing off their talents in the current program. Advanced may not need to be so high to really show that a company has deep expertise. Overall it was a very successful Oracle OpenWorld for Oracle partners of all sizes. There was progress made on making it a bigger and more relevant event. And also on catching up and maybe even leading in some cases with cloud opportunities for partners.

  • TOTD #166: Using NoSQL database in your Java EE 6 Applications on GlassFish - MongoDB for now!

    - by arungupta
    The Java EE 6 platform includes Java Persistence API to work with RDBMS. The JPA specification defines a comprehensive API that includes, but not restricted to, how a database table can be mapped to a POJO and vice versa, provides mechanisms how a PersistenceContext can be injected in a @Stateless bean and then be used for performing different operations on the database table and write typesafe queries. There are several well known advantages of RDBMS but the NoSQL movement has gained traction over past couple of years. The NoSQL databases are not intended to be a replacement for the mainstream RDBMS. As Philosophy of NoSQL explains, NoSQL database was designed for casual use where all the features typically provided by an RDBMS are not required. The name "NoSQL" is more of a category of databases that is more known for what it is not rather than what it is. The basic principles of NoSQL database are: No need to have a pre-defined schema and that makes them a schema-less database. Addition of new properties to existing objects is easy and does not require ALTER TABLE. The unstructured data gives flexibility to change the format of data any time without downtime or reduced service levels. Also there are no joins happening on the server because there is no structure and thus no relation between them. Scalability and performance is more important than the entire set of functionality typically provided by an RDBMS. This set of databases provide eventual consistency and/or transactions restricted to single items but more focus on CRUD. Not be restricted to SQL to access the information stored in the backing database. Designed to scale-out (horizontal) instead of scale-up (vertical). This is important knowing that databases, and everything else as well, is moving into the cloud. RBDMS can scale-out using sharding but requires complex management and not for the faint of heart. Unlike RBDMS which require a separate caching tier, most of the NoSQL databases comes with integrated caching. Designed for less management and simpler data models lead to lower administration as well. There are primarily three types of NoSQL databases: Key-Value stores (e.g. Cassandra and Riak) Document databases (MongoDB or CouchDB) Graph databases (Neo4J) You may think NoSQL is panacea but as I mentioned above they are not meant to replace the mainstream databases and here is why: RDBMS have been around for many years, very stable, and functionally rich. This is something CIOs and CTOs can bet their money on without much worry. There is a reason 98% of Fortune 100 companies run Oracle :-) NoSQL is cutting edge, brings excitement to developers, but enterprises are cautious about them. Commercial databases like Oracle are well supported by the backing enterprises in terms of providing support resources on a global scale. There is a full ecosystem built around these commercial databases providing training, performance tuning, architecture guidance, and everything else. NoSQL is fairly new and typically backed by a single company not able to meet the scale of these big enterprises. NoSQL databases are good for CRUDing operations but business intelligence is extremely important for enterprises to stay competitive. RDBMS provide extensive tooling to generate this data but that was not the original intention of NoSQL databases and is lacking in that area. Generating any meaningful information other than CRUDing require extensive programming. Not suited for complex transactions such as banking systems or other highly transactional applications requiring 2-phase commit. SQL cannot be used with NoSQL databases and writing simple queries can be involving. Enough talking, lets take a look at some code. This blog has published multiple blogs on how to access a RDBMS using JPA in a Java EE 6 application. This Tip Of The Day (TOTD) will show you can use MongoDB (a document-oriented database) with a typical 3-tier Java EE 6 application. Lets get started! The complete source code of this project can be downloaded here. Download MongoDB for your platform from here (1.8.2 as of this writing) and start the server as: arun@ArunUbuntu:~/tools/mongodb-linux-x86_64-1.8.2/bin$./mongod./mongod --help for help and startup optionsSun Jun 26 20:41:11 [initandlisten] MongoDB starting : pid=11210port=27017 dbpath=/data/db/ 64-bit Sun Jun 26 20:41:11 [initandlisten] db version v1.8.2, pdfile version4.5Sun Jun 26 20:41:11 [initandlisten] git version:433bbaa14aaba6860da15bd4de8edf600f56501bSun Jun 26 20:41:11 [initandlisten] build sys info: Linuxbs-linux64.10gen.cc 2.6.21.7-2.ec2.v1.2.fc8xen #1 SMP Fri Nov 2017:48:28 EST 2009 x86_64 BOOST_LIB_VERSION=1_41Sun Jun 26 20:41:11 [initandlisten] waiting for connections on port 27017Sun Jun 26 20:41:11 [websvr] web admin interface listening on port 28017 The default directory for the database is /data/db and needs to be created as: sudo mkdir -p /data/db/sudo chown `id -u` /data/db You can specify a different directory using "--dbpath" option. Refer to Quickstart for your specific platform. Using NetBeans, create a Java EE 6 project and make sure to enable CDI and add JavaServer Faces framework. Download MongoDB Java Driver (2.6.3 of this writing) and add it to the project library by selecting "Properties", "LIbraries", "Add Library...", creating a new library by specifying the location of the JAR file, and adding the library to the created project. Edit the generated "index.xhtml" such that it looks like: <h1>Add a new movie</h1><h:form> Name: <h:inputText value="#{movie.name}" size="20"/><br/> Year: <h:inputText value="#{movie.year}" size="6"/><br/> Language: <h:inputText value="#{movie.language}" size="20"/><br/> <h:commandButton actionListener="#{movieSessionBean.createMovie}" action="show" title="Add" value="submit"/></h:form> This page has a simple HTML form with three text boxes and a submit button. The text boxes take name, year, and language of a movie and the submit button invokes the "createMovie" method of "movieSessionBean" and then render "show.xhtml". Create "show.xhtml" ("New" -> "Other..." -> "Other" -> "XHTML File") such that it looks like: <head> <title><h1>List of movies</h1></title> </head> <body> <h:form> <h:dataTable value="#{movieSessionBean.movies}" var="m" > <h:column><f:facet name="header">Name</f:facet>#{m.name}</h:column> <h:column><f:facet name="header">Year</f:facet>#{m.year}</h:column> <h:column><f:facet name="header">Language</f:facet>#{m.language}</h:column> </h:dataTable> </h:form> This page shows the name, year, and language of all movies stored in the database so far. The list of movies is returned by "movieSessionBean.movies" property. Now create the "Movie" class such that it looks like: import com.mongodb.BasicDBObject;import com.mongodb.BasicDBObject;import com.mongodb.DBObject;import javax.enterprise.inject.Model;import javax.validation.constraints.Size;/** * @author arun */@Modelpublic class Movie { @Size(min=1, max=20) private String name; @Size(min=1, max=20) private String language; private int year; // getters and setters for "name", "year", "language" public BasicDBObject toDBObject() { BasicDBObject doc = new BasicDBObject(); doc.put("name", name); doc.put("year", year); doc.put("language", language); return doc; } public static Movie fromDBObject(DBObject doc) { Movie m = new Movie(); m.name = (String)doc.get("name"); m.year = (int)doc.get("year"); m.language = (String)doc.get("language"); return m; } @Override public String toString() { return name + ", " + year + ", " + language; }} Other than the usual boilerplate code, the key methods here are "toDBObject" and "fromDBObject". These methods provide a conversion from "Movie" -> "DBObject" and vice versa. The "DBObject" is a MongoDB class that comes as part of the mongo-2.6.3.jar file and which we added to our project earlier.  The complete javadoc for 2.6.3 can be seen here. Notice, this class also uses Bean Validation constraints and will be honored by the JSF layer. Finally, create "MovieSessionBean" stateless EJB with all the business logic such that it looks like: package org.glassfish.samples;import com.mongodb.BasicDBObject;import com.mongodb.DB;import com.mongodb.DBCollection;import com.mongodb.DBCursor;import com.mongodb.DBObject;import com.mongodb.Mongo;import java.net.UnknownHostException;import java.util.ArrayList;import java.util.List;import javax.annotation.PostConstruct;import javax.ejb.Stateless;import javax.inject.Inject;import javax.inject.Named;/** * @author arun */@Stateless@Namedpublic class MovieSessionBean { @Inject Movie movie; DBCollection movieColl; @PostConstruct private void initDB() throws UnknownHostException { Mongo m = new Mongo(); DB db = m.getDB("movieDB"); movieColl = db.getCollection("movies"); if (movieColl == null) { movieColl = db.createCollection("movies", null); } } public void createMovie() { BasicDBObject doc = movie.toDBObject(); movieColl.insert(doc); } public List<Movie> getMovies() { List<Movie> movies = new ArrayList(); DBCursor cur = movieColl.find(); System.out.println("getMovies: Found " + cur.size() + " movie(s)"); for (DBObject dbo : cur.toArray()) { movies.add(Movie.fromDBObject(dbo)); } return movies; }} The database is initialized in @PostConstruct. Instead of a working with a database table, NoSQL databases work with a schema-less document. The "Movie" class is the document in our case and stored in the collection "movies". The collection allows us to perform query functions on all movies. The "getMovies" method invokes "find" method on the collection which is equivalent to the SQL query "select * from movies" and then returns a List<Movie>. Also notice that there is no "persistence.xml" in the project. Right-click and run the project to see the output as: Enter some values in the text box and click on enter to see the result as: If you reached here then you've successfully used MongoDB in your Java EE 6 application, congratulations! Some food for thought and further play ... SQL to MongoDB mapping shows mapping between traditional SQL -> Mongo query language. Tutorial shows fun things you can do with MongoDB. Try the interactive online shell  The cookbook provides common ways of using MongoDB In terms of this project, here are some tasks that can be tried: Encapsulate database management in a JPA persistence provider. Is it even worth it because the capabilities are going to be very different ? MongoDB uses "BSonObject" class for JSON representation, add @XmlRootElement on a POJO and how a compatible JSON representation can be generated. This will make the fromXXX and toXXX methods redundant.
