• Review: ComponentOne Studio for Entity Framework

  - by Tim Murphy

  While I have always been a fan of libraries that improve coding efficiency and reduce code redundancy I have mostly been using ones that were in the public domain.  As part of the Geeks With Blogs Influencers program a got my hands on ComponentOne’s Studio for Entity Framework.  Below are my thought after working with the product for several weeks. My coding preference has always been maintainable code that is reusable across an enterprises protfolio.  Because of this my focus in reviewing this product is less on the RAD components and more on its benefits for layered applications using code first Entity Framework. Before we get into the pros and cons here is a summary of the main feature listed for SEF. Unified Data Context Virtual Data Access More Powerful Data Binding Pros The first thing that I found to my liking is the C1DataSource. It basically manages a cache for your Entity Model context.  Under RAD conditions this is setup automatically when you drop the object on a your design surface.  If you are like me and want to abstract you data management into a library it takes a little more work, but it is still acceptable and gains the same benefits. The second feature that I found beneficial is the definition of views with improved sorting and filtering.  Again the ease of use of these features is greater on the RAD side but no capabilities are missing when manipulating object in code. Linq has become my friend over the last couple of years and it was great to see that ComponentOne had ensured that it remained a first class citizen in their design.  When you look into this product yourself I would suggest taking a dive into LiveLinq which allow the joining of different data source types. As I went through discovering the features of this framework I appreciated the number of examples that they supplied for different uses.  Besides showing how to use SEF with WinForms, WPF and Silverlight they also showed how to accomplish tasks both RAD, code only and MVVM approaches. Cons The only area that I would really like to see improvement is in there level of detail in their documentation.  Specifically I would like to have seen some of the supporting code explained, such as what some supporting object did, in the examples instead of having to go to the programmer’s reference. I did find some times where currently existing projects had some trouble determining scope that the RAD controls were allowed, but I expect this is something that is in part end user related. Summary Overall I found the Studio for Entity Framework capable and well thought out.  If you are already using the Entity Framework this product will fit into your environment with little effort in return for greater flexibility and greater robustness in your solutions. Whether the $895 list price for a standard version works for you will depend on your return on investment. Smaller companies with only a small number of projects may not be able to stomach it, you get a full featured product that is supported by a well established company.  The more projects and the more code you have the greater your return on investment will be. Personally I intend to apply this product to some production systems and will probably have some tips and tricks in the future. del.icio.us Tags: ComponentOne,Studio for Entity Framework,Geeks With Blogs,Influencers,Product Reviews

• E-Business Suite Technology Stack Roadmap (April 2010) Now Available

  - by Steven Chan

  Keeping up with our E-Business Suite technology stack roadmap can be challenging.  Regular readers of this blog know that we certify new combinations and versions of Oracle products with the E-Business Suite every few weeks.  We also update our certification plans and roadmap as new third-party products like Microsoft Office 2010 and Firefox are announced or released.  Complicating matters further, various Oracle products leave Premier Support or are superceded by more-recent versions.This constant state of change means that any static representation of our roadmap is really a snapshot in time, and a snapshot that might begin to yellow and fade fairly quickly.  With that caveat in mind, here's this month's snapshot that I presented at the OAUG/Collaborate 2010 conference in Las Vegas last week:EBS Technology Stack Roadmap (April 2010)

• JavaOne Afterglow by Simon Ritter

  - by JuergenKress

  Last week was the eighteenth JavaOne conference and I thought it would be a good idea to write up my thoughts about how things went. Firstly thanks to Yoshio Terada for the photos, I didn't bother bringing a camera with me so it's good to have some pictures to add to the words. Things kicked off full-throttle on Sunday.  We had the Java Champions and JUG leaders breakfast, which was a great way to meet up with a lot of familiar faces and start talking all things Java.  At midday the show really started with the Strategy and Technical Keynotes.  This was always going to be tougher job than some years because there was no big shiny ball to reveal to the audience.  With the Java EE 7 spec being finalised a few months ago and Java SE 8, Java ME 8 and JDK8 not due until the start of next year there was not going to be any big announcement.  I thought both keynotes worked really well each focusing on the things most important to Java developers: Strategy One of the things that is becoming more and more prominent in many companies marketing is the Internet of Things (IoT).  We've moved from the conventional desktop/laptop environment to much more mobile connected computing with smart phones and tablets.  The next wave of the internet is not just billions of people connected, but 10s or 100s of billions of devices connected to the network, all generating data and providing much more precise control of almost any process you can imagine.  This ties into the ideas of Big Data and Cloud Computing, but implementation is certainly not without its challenges.  As Peter Utzschneider explained it's about three Vs: Volume, Velocity and Value.  All these devices will create huge volumes of data at very high speed; to avoid being overloaded these devices will need some sort of processing capabilities that can filter the useful data from the redundant.  The raw data then needs to be turned into useful information that has value.  To make this happen will require applications on devices, at gateways and on the back-end servers, all very tightly integrated.  This is where Java plays a pivotal role, write once, run everywhere becomes essential, having nine million developers fluent in the language makes it the defacto lingua franca of IoT.  There will be lots more information on how this will become a reality, so watch this space. Technical How do we make the IoT a reality, technically?  Using the game of chess Mark Reinhold, with the help of people like John Ceccarelli, Jasper Potts and Richard Bair, showed what you could do.  Using Java EE on the back end, Java SE and JavaFX on the desktop and Java ME Embedded and JavaFX on devices they showed a complete end-to-end demo. This was really impressive, using 3D features from JavaFX 8 (that's included with JDK8) to make a 3D animated Duke chess board.  Jasper also unveiled the "DukePad" a home made tablet using a Raspberry Pi, touch screen and accelerometer. Although the Raspberry Pi doesn't have earth shattering CPU performance (about the same level as a mid 1990s Pentium), it does have really quite good GPU performance so the GUI works really well.  The plans are all open sourced and available here.  One small, but very significant announcement was that Java SE will now be included with the NOOB and Raspbian Linux distros provided by the Raspberry Pi foundation (these can be found here).  No more hassle having to download and install the JDK after you've flashed your SD card OS image.  The finale was the Raspberry Pi powered chess playing robot.  Really very, very cool.  I talked to Jasper about this and he told me each of the chess pieces had been 3D printed and then he had to use acetone to give them a glossy finish (not sure what his wife thought of him spending hours in the kitchen in a gas mask!)  The way the robot arm worked was very impressive as it did not have any positioning data (like a potentiometer connected to each motor), but relied purely on carefully calibrated timings to get the arm to the right place.  Having done things like this myself in the past I know how easy it is to find a small error gets magnified into very big mistakes. Here's some pictures from the keynote: The "Dukepad" architecture Nice clear perspex case so you can see the innards. The very nice 3D chess set.  Maya's obviously a great tool.

• User Experience Highlights in Siebel: Direct from George Jacob

  - by mvaughan

  By Misha Vaughan and Kathy Miedema, Oracle Applications User Experience This is the first in a series of blog posts on the user experience (UX) highlights coming in various Oracle product families. You’ll see themes around productivity and efficiency, as well as a thoughtful approach to pushing UX capabilities into the underlying tooling. Of course, you can also expect to get an early look at the latest mobile offerings coming through these product lines.Today’s post is on Siebel. To learn more about what’s ahead, attend Siebel OpenWorld presentations. Our first interview is with George Jacob, the Group Vice President for CRM Applications. George Jacob Q: How would you describe the vision you have for the user experience of Siebel? A: Contemporary: Siebel runs in all browsers and all browser-capable devices using the latest web technology standards, such as Javascript, CSS, and HTML 5.Productive: Siebel is designed for a user experience that reduces clutter and user keystrokes.User-sensitive: The user experience enables Siebel to adapt easily to site and user preferences.Q: How are the UX features you have delivered so far resonating with customers? A:  Customers are very excited about our refresh of the Siebel user interface framework; the Siebel roadmap and user interface sessions at Oracle OpenWorld last year overflowed. We have had to turn back customer requests to participate in the early adopter program because we had more than we could handle. Customers are calling this a game-changer for Siebel.Q: So the UX highlights are popular? A: Yes, the UX highlights are very popular, although to a certain extent we expected this!  Q: What’s coming in Siebel on a mobile platform? A: Our current mobile offering is based on Windows Mobile (native application), and is fairly mature (over 5 years). The new Siebel Open User Interface Framework, by virtue of working on all browsers, will run – when it is released this year – on tablets and smartphones. This is one of the reasons a number of customers are most excited about our UX changes. Views of Siebel data on mobile devices Q: What are you working on now that you think is going to be exciting to customers at OOW? A: We are working on the Siebel Open User Interface Framework, to be released this year in the Siebel 2012 8.1.1.9 & 8.2.2.2 innovation packs. We are also working on Connected Mobile applications for Sales, Service, Consumer Goods and Pharmaceuticals, and Disconnected Mobile applications for Pharmaceuticals in the same release. We are building specialized applications that exploit the new UI framework for Telco Order Capture and for Life Sciences healthcare professional visits. Our 2012 delivery will be the foundation for further user experience enhancements, next year and beyond.Q: What do you want Siebel customers to know? A:  We are excited to be focused on improving the user experience of Siebel applications, and it is encouraging to see the positive feedback from Siebel customers and partners.If you would like to see more in the Siebel user experience, be sure to check out these sessions at OpenWorld: CON9700 - Siebel CRM Overview, Strategy, and Roadmap CON9703 - User Interface Innovations with the New Siebel “Open UI” CON9705 - Unleash the Power of “Open UI” CON9697 - Mobile Solutions for Siebel CRM

• ASP.NET MVC CRUD Validation

  - by Ricardo Peres

  One thing I didn’t refer on my previous post on ASP.NET MVC CRUD with AJAX was how to retrieve model validation information into the client. We want to send any model validation errors to the client in the JSON object that contains the ProductId, RowVersion and Success properties, specifically, if there are any errors, we will add an extra Errors collection property. Here’s how: 1: [HttpPost] 2: [AjaxOnly] 3: [Authorize] 4: public JsonResult Edit(Product product) 5: { 6: if (this.ModelState.IsValid == true) 7: { 8: using (ProductContext ctx = new ProductContext()) 9: { 10: Boolean success = false; 11:  12: ctx.Entry(product).State = (product.ProductId == 0) ? EntityState.Added : EntityState.Modified; 13:  14: try 15: { 16: success = (ctx.SaveChanges() == 1); 17: } 18: catch (DbUpdateConcurrencyException) 19: { 20: ctx.Entry(product).Reload(); 21: } 22:  23: return (this.Json(new { Success = success, ProductId = product.ProductId, RowVersion = Convert.ToBase64String(product.RowVersion) })); 24: } 25: } 26: else 27: { 28: Dictionary<String, String> errors = new Dictionary<String, String>(); 29:  30: foreach (KeyValuePair<String, ModelState> keyValue in this.ModelState) 31: { 32: String key = keyValue.Key; 33: ModelState modelState = keyValue.Value; 34:  35: foreach (ModelError error in modelState.Errors) 36: { 37: errors[key] = error.ErrorMessage; 38: } 39: } 40:  41: return (this.Json(new { Success = false, ProductId = 0, RowVersion = String.Empty, Errors = errors })); 42: } 43: } As for the view, we need to change slightly the onSuccess JavaScript handler on the Single view: 1: function onSuccess(ctx) 2: { 3: if (typeof (ctx.Success) != 'undefined') 4: { 5: $('input#ProductId').val(ctx.ProductId); 6: $('input#RowVersion').val(ctx.RowVersion); 7:  8: if (ctx.Success == false) 9: { 10: var errors = ''; 11:  12: if (typeof (ctx.Errors) != 'undefined') 13: { 14: for (var key in ctx.Errors) 15: { 16: errors += key + ': ' + ctx.Errors[key] + '\n'; 17: } 18:  19: window.alert('An error occurred while updating the entity: the model contained the following errors.\n\n' + errors); 20: } 21: else 22: { 23: window.alert('An error occurred while updating the entity: it may have been modified by third parties. Please try again.'); 24: } 25: } 26: else 27: { 28: window.alert('Saved successfully'); 29: } 30: } 31: else 32: { 33: if (window.confirm('Not logged in. Login now?') == true) 34: { 35: document.location.href = '<% 1: : FormsAuthentication.LoginUrl %>?ReturnURL=' + document.location.pathname; 36: } 37: } 38: } The logic is as this: If the Edit action method is called for a new entity (the ProductId is 0) and it is valid, the entity is saved, and the JSON results contains a Success flag set to true, a ProductId property with the database-generated primary key and a RowVersion with the server-generated ROWVERSION; If the model is not valid, the JSON result will contain the Success flag set to false and the Errors collection populated with all the model validation errors; If the entity already exists in the database (ProductId not 0) and the model is valid, but the stored ROWVERSION is different that the one on the view, the result will set the Success property to false and will return the current (as loaded from the database) value of the ROWVERSION on the RowVersion property. On a future post I will talk about the possibilities that exist for performing model validation, stay tuned!

• SQL Developer: Why Do You Require Semicolons When Executing SQL in the Worksheet?

  - by thatjeffsmith

  There are many database tools out there that support Oracle database. Oracle SQL Developer just happens to be the one that is produced and shipped by the same folks that bring you the database product. Several other 3rd party tools out there allow you to have a collection of SQL statements in their editor and execute them without requiring a statement delimiter (usually a semicolon.) Let’s look at a quick example: select * from scott.emp select * from hr.employees delete from HR_COPY.BEER where HR_COPY.BEER.STATE like '%West Virginia% In some tools, you can simply place your cursor on say the 2nd statement and ask to execute that statement. The tool assumes that the blank line between it and the next statement, a DELETE, serves as a statement delimiter. This is not bad in and of itself. However, it is very important to understand how your tools work. If you were to try the same trick by running the delete statement, it would empty my entire BEER table instead of just trimming out the breweries from my home state. SQL Developer only executes what you ask it to execute You can paste this same code into SQL Developer and run it without problems and without having to add semicolons to your statements. Highlight what you want executed, and hit Ctrl-Enter If you don’t highlight the text, here’s what you’ll see: See the statement at the cursor vs what SQL Developer actually executed? The parser looks for a query and keeps going until the statement is terminated with a semicolon – UNLESS it’s highlighted, then it assumes you only want to execute what is highlighted. In both cases you are being explicit with what is being sent to the database. Again, there’s not necessarily a ‘right’ or ‘wrong’ debate here. What you need to be aware of is the differences and to learn new workflows if you are moving from other database tools to Oracle SQL Developer. I say, when in doubt, back away from the tool, especially if you’re in production. Oh, and to answer the original question… Because we’re trying to emulate SQL*Plus behavior. You end statements in SQL*Plus with delimiters, and the default delimiter is a semicolon.

• OTN Database Developer Day in LA/OC

  - by shay.shmeltzer

  We are taking a little break from the Fusion OTN Developer Days, and instead we'll be taking part in several OTN Developer Days ran by the database team. The aim is to show what Oracle has to offer to various developer groups. As you might guess we specifically are going to be in the Java track. Specifically we are running a lab that will get you to experience Oracle JDeveloper (or OEPE) and will show you how to build an application based on EJB/JSF with Ajax UI. I'm going to be in the upcoming event on May 5th - if you are in the LA area and haven't experienced JDeveloper yet - come in and see what it is all about. Details here.

• Anticipating JavaOne 2012 – Number 17!

  - by Janice J. Heiss

  As I write this, JavaOne 2012 (September 30-October 4 in San Francisco, CA) is just over a week away -- the seventeenth JavaOne! I’ll resist the impulse to travel in memory back to the early days of JavaOne. But I will say that JavaOne is a little like your birthday or New Year’s in that it invites reflection, evaluation, and comparison. It’s a time when we take the temperature of Java and assess the world of information technology generally. At JavaOne, insight and information flow amongst Java developers like no other time of the year.This year, the status of Java seems more secure in the eyes of most Java developers who agree that Oracle is doing an acceptable job of stewarding the platform, and while the story is still in progress, few doubt that Oracle is engaging strongly with the Java community and wants to see Java thrive. From my perspective, the biggest news about Java is the growth of some 250 alternative languages for the JVM – from Groovy to Jython to JRuby to Scala to Clojure and on and on – offering both new opportunities and challenges. The JVM has proven itself to be unusually flexible, resulting in an embarrassment of riches in which, more and more, developers are challenged to find ways to optimally mix together several different languages on projects.    To the matter at hand -- I can say with confidence that Oracle is working hard to make each JavaOne better than the last – more interesting, more stimulating, more networking, and more fun! A great deal of thought and attention is being devoted to the task. To free up time for the 475 technical sessions/Birds of feather/Hands-on-Labs slots, the Java Strategy, Partner, and Technical keynotes will be held on Sunday September 30, beginning at 4:00 p.m.   Let’s not forget Java Embedded@JavaOne which is being held Wednesday, Oct. 3rd and Thursday, Oct. 4th at the Hotel Nikko. It will provide business decision makers, technical leaders, and ecosystem partners important information about Java Embedded technologies and new business opportunities.   This year's JavaOne theme is “Make the Future Java”. So come to JavaOne and make your future better by:--Choosing from 475 sessions given by the experts to improve your working knowledge and coding expertise --Networking with fellow developers in both casual and formal settings--Enjoying world-class entertainment--Delighting in one of the world’s great cities (my home town) Hope to see you there!

• ADF Faces now in Eclipse

  - by shay.shmeltzer

  The new version of Oracle Enterprise Pack for Eclipse was just release, and one of the key new feature it offers is integration of Oracle ADF Faces development in Eclipse. If you are serious about developing with JSF, you probably know by now that ADF Faces is the richest set of components out there both in terms of number of components and also the functionality they offer. The components offer a lot of Ajax functionality out of the box, and the framework also offers windowing, drag and drop, push, Javascript API, skinning and much more. OEPE makes it simple to build with ADF Faces and test run your application. Here is a basic tutorial that will get you all set up to use this combination. Once you do that, you can then do this:

• Security Issues with Single Page Apps

  - by Stephen.Walther

  Last week, I was asked to do a code review of a Single Page App built using the ASP.NET Web API, Durandal, and Knockout (good stuff!). In particular, I was asked to investigate whether there any special security issues associated with building a Single Page App which are not present in the case of a traditional server-side ASP.NET application. In this blog entry, I discuss two areas in which you need to exercise extra caution when building a Single Page App. I discuss how Single Page Apps are extra vulnerable to both Cross-Site Scripting (XSS) attacks and Cross-Site Request Forgery (CSRF) attacks. This goal of this blog post is NOT to persuade you to avoid writing Single Page Apps. I’m a big fan of Single Page Apps. Instead, the goal is to ensure that you are fully aware of some of the security issues related to Single Page Apps and ensure that you know how to guard against them. Cross-Site Scripting (XSS) Attacks According to WhiteHat Security, over 65% of public websites are open to XSS attacks. That’s bad. By taking advantage of XSS holes in a website, a hacker can steal your credit cards, passwords, or bank account information. Any website that redisplays untrusted information is open to XSS attacks. Let me give you a simple example. Imagine that you want to display the name of the current user on a page. To do this, you create the following server-side ASP.NET page located at http://MajorBank.com/SomePage.aspx: <%@Page Language="C#" %> <html> <head> <title>Some Page</title> </head> <body> Welcome <%= Request["username"] %> </body> </html> Nothing fancy here. Notice that the page displays the current username by using Request[“username”]. Using Request[“username”] displays the username regardless of whether the username is present in a cookie, a form field, or a query string variable. Unfortunately, by using Request[“username”] to redisplay untrusted information, you have now opened your website to XSS attacks. Here’s how. Imagine that an evil hacker creates the following link on another website (hackers.com): <a href="/SomePage.aspx?username=<script src=Evil.js></script>">Visit MajorBank</a> Notice that the link includes a query string variable named username and the value of the username variable is an HTML <SCRIPT> tag which points to a JavaScript file named Evil.js. When anyone clicks on the link, the <SCRIPT> tag will be injected into SomePage.aspx and the Evil.js script will be loaded and executed. What can a hacker do in the Evil.js script? Anything the hacker wants. For example, the hacker could display a popup dialog on the MajorBank.com site which asks the user to enter their password. The script could then post the password back to hackers.com and now the evil hacker has your secret password. ASP.NET Web Forms and ASP.NET MVC have two automatic safeguards against this type of attack: Request Validation and Automatic HTML Encoding. Protecting Coming In (Request Validation) In a server-side ASP.NET app, you are protected against the XSS attack described above by a feature named Request Validation. If you attempt to submit “potentially dangerous” content — such as a JavaScript <SCRIPT> tag — in a form field or query string variable then you get an exception. Unfortunately, Request Validation only applies to server-side apps. Request Validation does not help in the case of a Single Page App. In particular, the ASP.NET Web API does not pay attention to Request Validation. You can post any content you want – including <SCRIPT> tags – to an ASP.NET Web API action. For example, the following HTML page contains a form. When you submit the form, the form data is submitted to an ASP.NET Web API controller on the server using an Ajax request: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> </head> <body> <form data-bind="submit:submit"> <div> <label> User Name: <input data-bind="value:user.userName" /> </label> </div> <div> <label> Email: <input data-bind="value:user.email" /> </label> </div> <div> <input type="submit" value="Submit" /> </div> </form> <script src="Scripts/jquery-1.7.1.js"></script> <script src="Scripts/knockout-2.1.0.js"></script> <script> var viewModel = { user: { userName: ko.observable(), email: ko.observable() }, submit: function () { $.post("/api/users", ko.toJS(this.user)); } }; ko.applyBindings(viewModel); </script> </body> </html> The form above is using Knockout to bind the form fields to a view model. When you submit the form, the view model is submitted to an ASP.NET Web API action on the server. Here’s the server-side ASP.NET Web API controller and model class: public class UsersController : ApiController { public HttpResponseMessage Post(UserViewModel user) { var userName = user.UserName; return Request.CreateResponse(HttpStatusCode.OK); } } public class UserViewModel { public string UserName { get; set; } public string Email { get; set; } } If you submit the HTML form, you don’t get an error. The “potentially dangerous” content is passed to the server without any exception being thrown. In the screenshot below, you can see that I was able to post a username form field with the value “<script>alert(‘boo’)</script”. So what this means is that you do not get automatic Request Validation in the case of a Single Page App. You need to be extra careful in a Single Page App about ensuring that you do not display untrusted content because you don’t have the Request Validation safety net which you have in a traditional server-side ASP.NET app. Protecting Going Out (Automatic HTML Encoding) Server-side ASP.NET also protects you from XSS attacks when you render content. By default, all content rendered by the razor view engine is HTML encoded. For example, the following razor view displays the text “<b>Hello!</b>” instead of the text “Hello!” in bold: @{ var message = "<b>Hello!</b>"; } @message   If you don’t want to render content as HTML encoded in razor then you need to take the extra step of using the @Html.Raw() helper. In a Web Form page, if you use <%: %> instead of <%= %> then you get automatic HTML Encoding: <%@ Page Language="C#" %> <% var message = "<b>Hello!</b>"; %> <%: message %> This automatic HTML Encoding will prevent many types of XSS attacks. It prevents <script> tags from being rendered and only allows &lt;script&gt; tags to be rendered which are useless for executing JavaScript. (This automatic HTML encoding does not protect you from all forms of XSS attacks. For example, you can assign the value “javascript:alert(‘evil’)” to the Hyperlink control’s NavigateUrl property and execute the JavaScript). The situation with Knockout is more complicated. If you use the Knockout TEXT binding then you get HTML encoded content. On the other hand, if you use the HTML binding then you do not: <!-- This JavaScript DOES NOT execute --> <div data-bind="text:someProp"></div> <!-- This Javacript DOES execute --> <div data-bind="html:someProp"></div> <script src="Scripts/jquery-1.7.1.js"></script> <script src="Scripts/knockout-2.1.0.js"></script> <script> var viewModel = { someProp : "<script>alert('Evil!')<" + "/script>" }; ko.applyBindings(viewModel); </script>   So, in the page above, the DIV element which uses the TEXT binding is safe from XSS attacks. According to the Knockout documentation: “Since this binding sets your text value using a text node, it’s safe to set any string value without risking HTML or script injection.” Just like server-side HTML encoding, Knockout does not protect you from all types of XSS attacks. For example, there is nothing in Knockout which prevents you from binding JavaScript to a hyperlink like this: <a data-bind="attr:{href:homePageUrl}">Go</a> <script src="Scripts/jquery-1.7.1.min.js"></script> <script src="Scripts/knockout-2.1.0.js"></script> <script> var viewModel = { homePageUrl: "javascript:alert('evil!')" }; ko.applyBindings(viewModel); </script> In the page above, the value “javascript:alert(‘evil’)” is bound to the HREF attribute using Knockout. When you click the link, the JavaScript executes. Cross-Site Request Forgery (CSRF) Attacks Cross-Site Request Forgery (CSRF) attacks rely on the fact that a session cookie does not expire until you close your browser. In particular, if you visit and login to MajorBank.com and then you navigate to Hackers.com then you will still be authenticated against MajorBank.com even after you navigate to Hackers.com. Because MajorBank.com cannot tell whether a request is coming from MajorBank.com or Hackers.com, Hackers.com can submit requests to MajorBank.com pretending to be you. For example, Hackers.com can post an HTML form from Hackers.com to MajorBank.com and change your email address at MajorBank.com. Hackers.com can post a form to MajorBank.com using your authentication cookie. After your email address has been changed, by using a password reset page at MajorBank.com, a hacker can access your bank account. To prevent CSRF attacks, you need some mechanism for detecting whether a request is coming from a page loaded from your website or whether the request is coming from some other website. The recommended way of preventing Cross-Site Request Forgery attacks is to use the “Synchronizer Token Pattern” as described here: https://www.owasp.org/index.php/Cross-Site_Request_Forgery_%28CSRF%29_Prevention_Cheat_Sheet When using the Synchronizer Token Pattern, you include a hidden input field which contains a random token whenever you display an HTML form. When the user opens the form, you add a cookie to the user’s browser with the same random token. When the user posts the form, you verify that the hidden form token and the cookie token match. Preventing Cross-Site Request Forgery Attacks with ASP.NET MVC ASP.NET gives you a helper and an action filter which you can use to thwart Cross-Site Request Forgery attacks. For example, the following razor form for creating a product shows how you use the @Html.AntiForgeryToken() helper: @model MvcApplication2.Models.Product <h2>Create Product</h2> @using (Html.BeginForm()) { @Html.AntiForgeryToken(); <div> @Html.LabelFor( p => p.Name, "Product Name:") @Html.TextBoxFor( p => p.Name) </div> <div> @Html.LabelFor( p => p.Price, "Product Price:") @Html.TextBoxFor( p => p.Price) </div> <input type="submit" /> } The @Html.AntiForgeryToken() helper generates a random token and assigns a serialized version of the same random token to both a cookie and a hidden form field. (Actually, if you dive into the source code, the AntiForgeryToken() does something a little more complex because it takes advantage of a user’s identity when generating the token). Here’s what the hidden form field looks like: <input name=”__RequestVerificationToken” type=”hidden” value=”NqqZGAmlDHh6fPTNR_mti3nYGUDgpIkCiJHnEEL59S7FNToyyeSo7v4AfzF2i67Cv0qTB1TgmZcqiVtgdkW2NnXgEcBc-iBts0x6WAIShtM1″ /> And here’s what the cookie looks like using the Google Chrome developer toolbar: You use the [ValidateAntiForgeryToken] action filter on the controller action which is the recipient of the form post to validate that the token in the hidden form field matches the token in the cookie. If the tokens don’t match then validation fails and you can’t post the form: public ActionResult Create() { return View(); } [ValidateAntiForgeryToken] [HttpPost] public ActionResult Create(Product productToCreate) { if (ModelState.IsValid) { // save product to db return RedirectToAction("Index"); } return View(); } How does this all work? Let’s imagine that a hacker has copied the Create Product page from MajorBank.com to Hackers.com – the hacker grabs the HTML source and places it at Hackers.com. Now, imagine that the hacker trick you into submitting the Create Product form from Hackers.com to MajorBank.com. You’ll get the following exception: The Cross-Site Request Forgery attack is blocked because the anti-forgery token included in the Create Product form at Hackers.com won’t match the anti-forgery token stored in the cookie in your browser. The tokens were generated at different times for different users so the attack fails. Preventing Cross-Site Request Forgery Attacks with a Single Page App In a Single Page App, you can’t prevent Cross-Site Request Forgery attacks using the same method as a server-side ASP.NET MVC app. In a Single Page App, HTML forms are not generated on the server. Instead, in a Single Page App, forms are loaded dynamically in the browser. Phil Haack has a blog post on this topic where he discusses passing the anti-forgery token in an Ajax header instead of a hidden form field. He also describes how you can create a custom anti-forgery token attribute to compare the token in the Ajax header and the token in the cookie. See: http://haacked.com/archive/2011/10/10/preventing-csrf-with-ajax.aspx Also, take a look at Johan’s update to Phil Haack’s original post: http://johan.driessen.se/posts/Updated-Anti-XSRF-Validation-for-ASP.NET-MVC-4-RC (Other server frameworks such as Rails and Django do something similar. For example, Rails uses an X-CSRF-Token to prevent CSRF attacks which you generate on the server – see http://excid3.com/blog/rails-tip-2-include-csrf-token-with-every-ajax-request/#.UTFtgDDkvL8 ). For example, if you are creating a Durandal app, then you can use the following razor view for your one and only server-side page: @{ Layout = null; } <!DOCTYPE html> <html> <head> <title>Index</title> </head> <body> @Html.AntiForgeryToken() <div id="applicationHost"> Loading app.... </div> @Scripts.Render("~/scripts/vendor") <script type="text/javascript" src="~/App/durandal/amd/require.js" data-main="/App/main"></script> </body> </html> Notice that this page includes a call to @Html.AntiForgeryToken() to generate the anti-forgery token. Then, whenever you make an Ajax request in the Durandal app, you can retrieve the anti-forgery token from the razor view and pass the token as a header: var csrfToken = $("input[name='__RequestVerificationToken']").val(); $.ajax({ headers: { __RequestVerificationToken: csrfToken }, type: "POST", dataType: "json", contentType: 'application/json; charset=utf-8', url: "/api/products", data: JSON.stringify({ name: "Milk", price: 2.33 }), statusCode: { 200: function () { alert("Success!"); } } }); Use the following code to create an action filter which you can use to match the header and cookie tokens: using System.Linq; using System.Net.Http; using System.Web.Helpers; using System.Web.Http.Controllers; namespace MvcApplication2.Infrastructure { public class ValidateAjaxAntiForgeryToken : System.Web.Http.AuthorizeAttribute { protected override bool IsAuthorized(HttpActionContext actionContext) { var headerToken = actionContext .Request .Headers .GetValues("__RequestVerificationToken") .FirstOrDefault(); ; var cookieToken = actionContext .Request .Headers .GetCookies() .Select(c => c[AntiForgeryConfig.CookieName]) .FirstOrDefault(); // check for missing cookie or header if (cookieToken == null || headerToken == null) { return false; } // ensure that the cookie matches the header try { AntiForgery.Validate(cookieToken.Value, headerToken); } catch { return false; } return base.IsAuthorized(actionContext); } } } Notice that the action filter derives from the base AuthorizeAttribute. The ValidateAjaxAntiForgeryToken only works when the user is authenticated and it will not work for anonymous requests. Add the action filter to your ASP.NET Web API controller actions like this: [ValidateAjaxAntiForgeryToken] public HttpResponseMessage PostProduct(Product productToCreate) { // add product to db return Request.CreateResponse(HttpStatusCode.OK); } After you complete these steps, it won’t be possible for a hacker to pretend to be you at Hackers.com and submit a form to MajorBank.com. The header token used in the Ajax request won’t travel to Hackers.com. This approach works, but I am not entirely happy with it. The one thing that I don’t like about this approach is that it creates a hard dependency on using razor. Your single page in your Single Page App must be generated from a server-side razor view. A better solution would be to generate the anti-forgery token in JavaScript. Unfortunately, until all browsers support a way to generate cryptographically strong random numbers – for example, by supporting the window.crypto.getRandomValues() method — there is no good way to generate anti-forgery tokens in JavaScript. So, at least right now, the best solution for generating the tokens is the server-side solution with the (regrettable) dependency on razor. Conclusion The goal of this blog entry was to explore some ways in which you need to handle security differently in the case of a Single Page App than in the case of a traditional server app. In particular, I focused on how to prevent Cross-Site Scripting and Cross-Site Request Forgery attacks in the case of a Single Page App. I want to emphasize that I am not suggesting that Single Page Apps are inherently less secure than server-side apps. Whatever type of web application you build – regardless of whether it is a Single Page App, an ASP.NET MVC app, an ASP.NET Web Forms app, or a Rails app – you must constantly guard against security vulnerabilities.

• TSAM 11gR1

  - by todd.little

  The Tuxedo System and Application Monitor (TSAM) 11gR1 release provides powerful new application monitoring capabilities, as well as significant improvements in ease of use. The first thing users will notice is the completely redesigned user interface in the TSAM console. Based on Oracle ADF, the console is much easier to navigate, provides a Web 2.0 style interface with dynamically updating panels, and a look and feel familiar to those that have used Oracle Enterprise Manager. Monitoring data can be viewed in both tabular and graphical form and exported to Excel for further analysis. A number of new metrics are collected and displayed in this release. Call path monitoring now displays CPU time, message size, total transport time, and client address giving even more end-to-end information about a specific Tuxedo request. As well the call path display has been completely revamped to make it much easier to see the branches of the call path. The call pattern display now provides statistics on successful vs failed calls, system and application failures, and end-to-end average elapsed time. Service monitoring now displays minimum and maximum message size, CPU usage, and client address. System server monitoring now includes monitoring the SALT gateway servers to provide detailed performance metrics about those servers. Perhaps the most significant new feature is the consolidation of alert definitions and policy management. In previous versions of TSAM, some alerts were defined and checked on the monitored systems while others were defined and checked in the console. Policy management could be performed on both the monitored node via environment variable or command, as well as from the console. Now all alert definitions and policy definitions are only made using the console. For alerts this means that regardless of where the alert is evaluated it is defined in one and only one place. Thus the plug-in alert mechanism of previous releases can now be managed using the TSAM console, making SLA alert definition much easier and cleaner. Finally there is support in TSAM for monitoring rehosted mainframe applications. The newly announced Oracle Tuxedo Application Runtime for CICS and Batch can be monitored in the TSAM console using traditional mainframe views of the application such as regions. Look for a future blog entry with more details on this as well as some entries providing a glimpse of the console. TSAM gives users a single point for monitoring the performance of all of their Tuxedo applications.

• Do You Develop Your PL/SQL Directly in the Database?

  - by thatjeffsmith

  I know this sounds like a REALLY weird question for many of you. Let me make one thing clear right away though, I am NOT talking about creating and replacing PLSQL objects directly into a production environment. Do we really need to talk about developers in production again? No, what I am talking about is a developer doing their work from start to finish in a development database. These are generally available to a development team for building the next and greatest version of your databases and database applications. And of course you are using a third party source control system, right? Last week I was in Tampa, FL presenting at the monthly Suncoast Oracle User’s Group meeting. Had a wonderful time, great questions and back-and-forth. My favorite heckler was there, @oraclenered, AKA Chet Justice.  I was in the middle of talking about how it’s better to do your PLSQL work in the Procedure Editor when Chet pipes up - Don’t do it that way, that’s wrong Just press play to edit the PLSQL directly in the database Or something along those lines. I didn’t get what the heck he was talking about. I had been showing how the Procedure Editor gives you much better feedback and support when working with PLSQL. After a few back-and-forths I got to what Chet’s main objection was, and again I’m going to paraphrase: You should develop offline in your SQL worksheet. Don’t do anything in the database until it’s done. I didn’t understand. Were developers expected to be able to internalize and mentally model the PL/SQL engine, see where their errors were, etc in these offline scripts? No, please give Chet more credit than that. What is the ideal Oracle Development Environment? If I were back in the ‘real world’ of database development, I would do all of my development outside of the ‘dev’ instance. My development process looks a little something like this: Do I have a program that already does something like this – copy and paste Has some smart person already written something like this – copy and paste Start typing in the white-screen-of-panic and bungle along until I get something that half-works Tweek, debug, test until I have fooled my subconscious into thinking that it’s ‘good’ As you might understand, I don’t want my co-workers to see the evolution of my code. It would seriously freak them out and I probably wouldn’t have a job anymore (don’t remind me that I already worked myself out of development.) So here’s what I like to do: Run a Local Instance of Oracle on my Machine and Develop My Code Privately I take a copy of development – that’s what source control is for afterall – and run it where no one else can see it. I now get to be my own DBA. If I need a trace – no problem. If I want to run an ASH report, no worries. If I need to create a directory or run some DataPump jobs, that’s all on me. Now when I get my code ‘up to snuff,’ then I will check it into source control and compile it into the official development instance. So my teammates suddenly go from seeing no program, to a mostly complete program. Is this right? If not, it doesn’t seem wrong to me. And after talking to Chet in the car on the way to the local cigar bar, it seems that he’s of the same opinion. So what’s so wrong with coding directly into a development instance? I think ‘wrong’ is a bit strong here. But there are a few pitfalls that you might want to look out for. A few come to mind – and I’m sure Chet could add many more as my memory fails me at the moment. But here goes: Development instance isn’t properly backed up – would hate to lose that work Development is wiped once a week and copied over from Prod – don’t laugh Someone clobbers your code You accidentally on purpose clobber someone else’s code The more developers you have in a single fish pond, the greater chance something ‘bad’ will happen This Isn’t One of Those Posts Where I Tell You What You Should Be Doing I realize many shops won’t be open to allowing developers to stage their own local copies of Oracle. But I would at least be aware that many of your developers are probably doing this anyway – with or without your tacit approval. SQL Developer can do local file tracking, but you should be using Source Control too! I will say that I think it’s imperative that you control your source code outside the database, even if your development team is comprised of a single developer. Store your source code in a file, and control that file in something like Subversion. You would be shocked at the number of teams that do not use a source control system. I know I continue to be shocked no matter how many times I meet another team running by the seat-of-their-pants. I’d love to hear how your development process works. And of course I want to know how SQL Developer and the rest of our tools can better support your processes. And one last thing, if you want a fun and interactive presentation experience, be sure to have Chet in the room

• Vodacom Call Center Management on the NetBeans Platform

  - by Geertjan

  If you live in South Africa, you know about Vodacom. Vodacom is one of the dominant mobile communication companies in South Africa, and beyond, providing voice, messaging, data, and similar mobile services. Inside Vodacom there's an application named Helios, which is a call centre application that had its inception in 2009 and consists of two parts. Firstly, a web-based front-end that allows a call centre agent to service subscribers using a Google-like search on a knowledge base structured as a collection of FAQs. The web-based front-end uses plain-old HTML + CSS + a good helping of JQuery and JQueryUI. This is delivered via JSR-168 portlets running on a cluster of IBM Portal 6 servers. In turn, the portlets communicate via RMI with several back-end EJB's containing the business logic. These EJB's are deployed on a cluster of Weblogic Application Servers, version 10.3.6. The second part is a NetBeans Platform application used for maintaining and constructing the knowledge base, i.e., the back-end of the web-based front-end. Helios is also used for a number of other maintenance functions, such as access permissions, user maintenance, and news bulletins. Below, in the web-based front-end, call centre agents can enter search terms and are presented with a number of FAQs from the knowledge base. Upon selecting a FAQ article, the agent is presented with the article text, the process to guide the subscriber, system checks that display information specific to the subscriber, and links to related applications and articles: Below, you can see that applications are searchable and can be accessed using the same web-based front-end as shown above. And, as can be seen below, knowledge base FAQs are maintained using the Helios Maintenance Application, which is the Vodacom application built on the NetBeans Platform: Several thousand call centre agent user accounts are administered using the Helios Maintenance Application. Below the main FAQ page is shown, together with the About dialog: Vodacom is happy with the back-end NetBeans Platform application. However, the front-end stack runs on quite old technology. Ideally Vodacom would like to migrate the portlets to Oracle Weblogic Portal or Oracle WebCenter, but this hasn't been accomplished yet. Migrating makes sense as the rest of the application server environment consists entirely of Oracle products.

• FAQ: Reshipping a Sun Certification

  - by Paul Sorensen

  If you obtained a Sun Certification before September 1, 2010, your success kit was shipped to the mailing address on record in your profile at certmanager.net/sun. At this time, if you require a reshipment for any reason of your original Sun Certification Certificate (it got damaged in the mail, you did not receive it, it needs to be sent to a different address, etc...), you will now receive access to an electronic reproduction of your original Certificate called an eCertificate. The Sun Certification ID card is no longer available and cannot be ordered from Oracle. This is to allow us to streamline this reshipping process and allow candidates to receive these certificates as quickly as possible.Candidates who earned a Java, Oracle Solaris, MySQL, NetBeans or OpenOffice.org certification on or after September 1, 2010 will receive their success kits in the mail within 6-8 weeks of completing the final certification requirement.

• Change sysout logging level for Weblogic

  - by Justin Voss

  When I run a local copy of Weblogic, I like to see the output in the console so that I can observe my app's logging messages. But, Weblogic spits out a lot of log messages I don't care about, like these: [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' 08-29-2010 01:02:21 INFO Getting a JNDI connection [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' 08-29-2010 01:02:21 INFO Connection Returned.

• Spotlight on a career path: Paul, Business Development Consultant

  - by Maria Sandu

  I came to work for Oracle in November 2012 as a Customer Intelligence Representative and since then I was promoted to a Business Development Consultant, for Commercial Industries in the UK, based in Dublin. My background was primarily in Logistics, working for such companies as Indaver Ireland, Wincanton and P&O. I spent 10 years working in this industry and gained experience in negotiating with customers and suppliers in order to meet the needs of both, monitoring the quality and quantity of goods as well as the efficiency and organisation of the movement and storage of products. I decided to move from my logistics career in 2009 to study Information Technology in D.I.T. This was a challenge for me to move my career path; however the lectures at the college helped me significantly with the ability to understand how IT can have an effect on how businesses operate. Following on from college I came to work for Oracle. This also presented challenges but the training I received and the encouragement from management helped me understand that the same business rules apply no matter what background you come from. I have also learnt that using my past experience in working with customers and suppliers in Logistics has helped me understand how to meet customer’s needs. Oracle has offered me excellent training such as Sandler Sales Techniques and John Costigan. I continue to get all the training that I need to develop my career.

• Walking to the North Pole to raise money to protect children from cruelty.

  - by jessica.ebbelaar

  Hi, my name is Luca. I joined Oracle in 2005 and I am currently working as a Dell EMEA Channel Manager UK, Ireland and Iberia and I am responsible for the Oracle Dell relationship for the above 3 countries. On the 31st of March 2011 I will set out to complete the ultimate challenge. I will walk and ski across the frozen Arctic to the Top of The World: the GEOGRAPHIC North Pole. While dragging all my supplies over 60 Nautical miles of moving sea ice, in temperatures as low as minus 30 degrees Celsius. I will spend 8 to 10 days preparing, working, living and travelling to the North Pole to 90 degree north. In November I spent a full week of training for this trip.( watch my video). This gave me the opportunity to meet the rest of the team, testing all the gear and carrying an 18inch tyre around the country side for 8 hours per day. I am honored to embark this challenging journey to support the National Society for the Prevention of Cruelty to Children (NSPCC). The NSPCC helped more than 750,000 young people to speak out for the first time about abuse they had suffered. I am a firm believer that in order to build a stronger, healthier and wiser society we need to support and help future generations from the beginning of their life journey. This is why cruelty to children must stop. FULL STOP.   Through Virgin Money Giving, you can sponsor me and donations will be quickly processed and passed to NSPCC. Virgin Money Giving is a non-profit organization and will claim gift aid on a charity's behalf where the donor is eligible for this. If you are a UK tax payer please don't forget to select Gift Aid. Gift Aid is great because it means charities get extra money added to their donations at no extra cost to the donor. For every £1 donated, the charity currently receives £1.28 when you add Gift Aid. Anyone who would like to find out more can visit my Facebook page ‘Luca North Pole charity fundraising trip’ I really appreciate all your support and thank you for supporting the NSPCC.
