  • Using ASP .NET Membership and Profile with MVC, how can I create a user and set it to HttpContext.Cu

    - by Jeremy Gruenwald
    I've read the other questions on the topic of MVC membership and profiles, but I'm missing something. I implemented a custom Profile object in code as described by Joel here: http://stackoverflow.com/questions/426609/asp-net-membership-how-to-assign-profile-values I can't get it to work when I'm creating a new user, however. When I do this: Membership.CreateUser(userName, password); Roles.AddUserToRole(userName, "MyRole"); the user is created and added to a role in the database, but HttpContext.Current.User is still empty, and Membership.GetUser() returns null, so this (from Joel's code) doesn't work: static public AccountProfile CurrentUser { get { return (AccountProfile) (ProfileBase.Create(Membership.GetUser().UserName)); } } AccountProfile.CurrentUser.FullName = "Snoopy"; I've tried calling Membership.GetUser(userName) and setting Profile properties that way, but the set properties remain empty, and calling AccountProfile.CurrentUser(userName).Save() doesn't put anything in the database. I've also tried indicating that the user is valid & logged in, by calling Membership.ValidateUser, FormsAuthentication.SetAuthCookie, etc., but the current user is still null or anonymous (depending on the state of my browser cookies). I have the feeling I'm missing some essential piece of understanding about how Membership, Authentication, and Profiles fit together. Do I have to do a round trip before the current User will be populated? Any advice would be much appreciated.

  • Sql Querying, group relationships

    - by Jordan
    Hi, Suppose I have two tables: Group ( id integer primary key, someData1 text, someData2 text ) GroupMember ( id integer primary key, group_id foreign key to Group.id, someData text ) I'm aware that my SQL syntax is not correct :) Hopefully is clear enough. My problem is this: I want to load a group record and all the GroupMember records associated with that group. As I see it, there are two options. A single query: SELECT Group.id, Group.someData1, Group.someData2 GroupMember.id, GroupMember.someData FROM Group INNER JOIN GroupMember ... WHERE Group.id = 4; Two queries: SELECT id, someData2, someData2 FROM Group WHERE id = 4; SELECT id, someData FROM GroupMember WHERE group_id = 4; The first solution has the advantage of only being one database round trip, but has the disadvantage of returning redundant data (All group data is duplicated for every group member) The second solution returns no duplicate data but involves two round trips to the database. What is preferable here? I suppose there's some threshold such that if the group sizes become sufficiently large, the cost of returning all the redundant data is going to be greater than the overhead involved with an additional database call. What other things should I be thinking about here? Thanks, Jordan

  • Flex 4 vs JavaScript Options (Cappuccino, JQuery, etc.)

    - by user320681
    Rehashing an older post: http://stackoverflow.com/questions/1570070/jquery-vs-flex-choosing-a-platform-for-saas We are preparing to develop an application that is exceptionally dynamic and interactive. It's particularly heavy on the graphics side. We are 85% convinced that Adobe Flash built atop Flex is the right path to take, however Cappuccino is quite nice and seems as though it may be able to nearly fit the bill. The only pause we have right now is portability for the iPhone. With the lack of blessings from Apple we will most certainly have to create a 2nd interface for the iPhone for the site, however... Having two interfaces may not be bad as it will likely have to be custom anyway to take advantage of the differences that it affords. Any further thoughts or reevaluations of points enumerated in the noted article? Further, Flex 4 adds a lot of strength to the position mentioned previously regarding UI development. Fx4 is very nice vs Fx3 and shaves 90% from the development time when coupled with Flash Catalyst, which is not really always fully appropriate, but with some round trip tricks it seems as though it can cut through things rather well... Please do advise and many thanks.

  • How to forward a 'saved' request stream to another Action within the same controller?

    - by Moe Howard
    We have a need to chunk-up large http requests sent by our mobile devices. These smaller chunk streams are merged to a file on the server. Once all chunks are received we need a way to submit the saved merged request to an another method(Action) within the same controller that will process this large http request. How can this be done? The code we tried below results in the service hanging. Is there a way to do this without a round-trip? //Open merged chunked file FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read); //Read steam support variables int bytesRead = 0; byte[] buffer = new byte[1024]; //Build New Web Request. The target Action is called "Upload", this method we are in is called "UploadChunk" HttpWebRequest webRequest; webRequest = (HttpWebRequest)WebRequest.Create(Request.Url.ToString().Replace("Chunk", string.Empty)); webRequest.Method = "POST"; webRequest.ContentType = "text/xml"; webRequest.KeepAlive = true; webRequest.Timeout = 600000; webRequest.ReadWriteTimeout = 600000; webRequest.Credentials = System.Net.CredentialCache.DefaultCredentials; Stream webStream = webRequest.GetRequestStream(); //Hangs here, no errors, just hangs I have looked into using RedirectToAction and RedirecctToRoute but these methods don't fit well with what we are looking to do as we cannot edit the Request.InputStream (as it is read-only) to carry out large request stream. Thanks, Moe

  • Understanding byte order and functions like CFSwapInt32HostToBig

    - by Typeoneerror
    I've got an enumeration in my game. A simple string message with an appended PacketType is being sent with the message (so it knows what to do with the message) over GameKit WIFI connection. I used Apple's GKRocket sample code as a starting point. The code itself is working fantastically; I just want to understand what the line with CFSwapInt32HostToBig is doing. What on earth does that do? and why does it need to do it? My guess is that it's making sure the PacketType value can be converted to an unsigned integer so it can send it reliably, but that doesn't sound all that correct to me. The documentation states "Converts a 32-bit integer from big-endian format to the host’s native byte order." but I don't understand what the means really. typedef enum { PacketTypeStart, // packet to notify games to start PacketTypeRequestSetup, // server wants client info PacketTypeSetup, // send client info to server PacketTypeSetupComplete, // round trip made for completion PacketTypeTurn, // packet to notify game that a turn is up PacketTypeRoll, // packet to send roll to players PacketTypeEnd // packet to end game } PacketType; // .... - (void)sendPacket:(NSData *)data ofType:(PacketType)type { NSLog(@"sendPacket:ofType(%d)", type); // create the data with enough space for a uint NSMutableData *newPacket = [NSMutableData dataWithCapacity:([data length]+sizeof(uint32_t))]; // Data is prefixed with the PacketType so the peer knows what to do with it. uint32_t swappedType = CFSwapInt32HostToBig((uint32_t)type); // add uint to data [newPacket appendBytes:&swappedType length:sizeof(uint32_t)]; // add the rest of the data [newPacket appendData:data]; // Send data checking for success or failure NSError *error; BOOL didSend = [_gkSession sendDataToAllPeers:newPacket withDataMode:GKSendDataReliable error:&error]; if (!didSend) { NSLog(@"error in sendDataToPeers: %@", [error localizedDescription]); } }

  • Finding latency issues (stalls) in embedded Linux systems

    - by camh
    I have an embedded Linux system running on an Atmel AT91SAM9260EK board on which I have two processes running at real-time priority. A manager process periodically "pings" a worker process using POSIX message queues to check the health of the worker process. Usually the round-trip ping takes about 1ms, but very occasionally it takes much longer - about 800ms. There are no other processes that run at a higher priority. It appears the stall may be related to logging (syslog). If I stop logging the problem seems to go away. However it makes no difference if the log file is on JFFS2 or NFS. No other processes are writing to the "disk" - just syslog. What tools are available to me to help me track down why these stalls are occurring? I am aware of latencytop and will be using that. Are there some other tools that may be more useful? Some details: Kernel version: 2.6.32.8 libc (syslog functions): uClibc 0.9.30.1 syslog: busybox 1.15.2

  • Backbone Model fetched from Lithium controller is not loaded properly in bb Model

    - by Nilesh Kale
    I'm using backbone.js and Lithium. I'm fetching a model from the server by passing in a _id that is received as a hidden parameter on the page. The database MongoDB has stored the data correctly and can be viewed from console as: { "_id" : ObjectId("50bb82694fbe3de417000001"), "holiday_name" : "SHREE15", "description": "", "star_rating" : "3", "holiday_type" : "family", "rooms" : "1", "adults" : "2", "child" :"0", "emails" : "" } The Lithium Model class is so: class Holidays extends \lithium\data\Model { public $validates = array( 'holiday_name' => array( array( 'notEmpty', 'required' => true, 'message' => 'Please key-in a holiday name! (eg. Family trip for summer holidays)' ))); } The backbone Holiday model is so: window.app.IHoliday = Backbone.Model.extend({ urlRoot: HOLIDAY_URL, idAttribute: "_id", id: "_id", // Default attributes for the holiday. defaults: { }, // Ensure that each todo created has `title`. initialize: function(props) { }, The code for backbone/fetch is: var Holiday = new window.app.IHoliday({ _id: holiday_id }); Holiday.fetch( { success: function(){ alert('Holiday fetched:' + JSON.stringify(Holiday)); console.log('HOLIDAY Fetched: \n' + JSON.stringify(Holiday)); console.log('Holiday name:' + Holiday.get('holiday_name')); } } ); Lithium Controller Code is: public function load($holiday_id) { $Holiday = Holidays::find($holiday_id); return compact('Holiday'); } PROBLEM: The output of the backbone model fetched from server is as below and the Holiday model is not correctly 'formed' when data returns into backbone Model: HOLIDAY Fetched: {"_id":"50bb82694fbe3de417000001","Holiday":{"_id":"50bb82694fbe3de417000001","holiday_name":"SHREE15","description":"","star_rating":"3","holiday_type":"family","rooms":"1","adults":"2","child":"0","emails":""}} iplann...view.js (line 68) Holiday name:undefined Clearly there is some issue when the data is passed/translated from Lithium and loaded up as a model into backbone Holiday model. Is there something very obviously wrong in my code?

  • How do I simulate "Is In" using Linq2Sql

    - by flipdoubt
    I often find myself with a list of disconnected Linq2Sql objects or keys that I need to re-select from a Linq2Sql data-context to update or delete in the database. If this were SQL, I would use IS IN in the SQL WHERE clause, but I am stuck with what to do in Linq2Sql. Here is a sample of what I would like to write: public void MarkValidated(IList<int> idsToValidate) { using(_Db.NewSession()) // Instatiates new DataContext { // ThatAreIn <- this is where I am stuck var items = _Db.Items.ThatAreIn(idsToValidate).ToList(); foreach(var item in items) item.Validated = DateTime.Now; _Db.SubmitChanges(); } // Disposes of DataContext } Or: public void DeleteItems(IList<int> idsToDelete) { using(_Db.NewSession()) // Instatiates new DataContext { // ThatAreIn <- this is where I am stuck var items = _Db.Items.ThatAreIn(idsToValidate); _Db.Items.DeleteAllOnSubmit(items); _Db.SubmitChanges(); } // Disposes of DataContext } Can I get this done in one trip to the database? If so, how? Is it possible to send all those ints to the database as a list of parameters and is that more efficient than doing a foreach over the list to select each item one at a time?

  • Why is cell phone software is still so primitive?

    - by Tomislav Nakic-Alfirevic
    I don't do mobile development, but it strikes me as odd that features like this aren't available by default on most phones: full text search: searches all address book contents, messages, anything else being a plus better call management: e.g. a rotating audio call log, meaning you always have the last N calls recorded for your listening pleasure later (your little girl just said her first "da-da" while you were on a business trip, you had a telephone job interview, you received complex instructions to do something etc.) bluetooth remote control (like e.g. anyRemote, but available by default on a bluetooth phone) no multitasking capabilities worth mentioning and in general no e.g. weekly software updates, making the phone much more usable (even if it had to be done over USB, rather than over the network). I'm sure I was dumbfounded by the lack or design of other features as well, but they don't come to mind right now. To clarify, I'm not talking about smartphones here: my plain, 2-year old phone has a CPU an order of magnitude faster than my first PC, about as much storage space and it's ridiculous how bad (slow, unwieldy) the software is and it's not one phone or one manufacturer. What keeps the (to me) obvious software functionality vacuum on a capable hardware platform from being filled up?

  • Why does the Combo.SelectedValue get lost after some time

    - by tzup
    So I have this asp:DropDownList on a page. It renders like this (in IE7): <select name="ctl00$cphFilter$cbLista" onchange="javascript:setTimeout('__doPostBack(\'ctl00$cphFilter$cbLista\',\'\')', 0)" id="ctl00_cphFilter_cbLista" class="agsSelect"> <option selected="selected" value="4350">A</option> <option value="4352">B</option> <option value="4349">C</option> <option value="4348">D</option> And then I have a grid and a button on the same page. When the user clicks the button the selected item of the dropdown is read (well a datasource object reads it) and the grid does a databind after a trip to a DB where it gets some data based on that selected value. This works fine most of the time. However sometimes, the selection in the dropdownlist seems to get lost even though the rendered page says the A is the selected item. The datasource object is defined like this: <asp:ObjectDataSource ID="dsVM" runat="server" EnablePaging="False" SelectMethod="Select" SortParameterName="sort" TypeName="X.Business.Entities.LPVM.BE"> <SelectParameters> <asp:ControlParameter Name="listaId" Type="Int32" ControlID="cphFilter$cbLista" PropertyName="SelectedValue" /> </SelectParameters> </asp:ObjectDataSource> Any ideas why the grid would reload its data with a select parameter that is 0 instead of the selected value of the dropdownlist? EDIT Suppose the dropdownlist is bound, the user selected B and the grid is bound as well and shows the right data. Now, I wait 2 minutes and I click the Refresh button. Surprisingly, at this particular moment the dropdownlist.SelectedValue (which I already know it was 4352 before I clicked because that's how it looks in the rendered page) is actually an empty string. Where did the value go?

  • How can we best represent the SDLC process as a board game?

    - by Innogetics
    I recently got interested in financial board games and saw how they can be very useful in educating children about certain concepts. It got me thinking whether it was also possible to represent certain aspects of executing a software project via a boardgame and make it fun. Here are a few things that I have come up so far: human resources and tools / techniques are represented as cards. requirements are also represented as cards, which are dealt equally to each player, and the objective is to move all requirement cards through an "SDLC" board (one per player) that represent a series of squares grouped according to phases (design all the way to deployment) the passage of time is represented in a main square board like monopoly, and completing a trip around the board (passing "Go") allows the player to move each of the requirement cards a number of steps through the SDLC board depending on the capability of the resource cards (senior programmer allows one requirement to move two squares in the dev phase, junior programmer only one, etc.) players will start with play money representing the project budget, and at every pass at "Go" is payday. the player is out of the game if he runs out of funds. the main board also has "chance" / "risk" cards, which represent things that can mess up a project. damage is applied at the roll of a die, and chance modifiers depend on whether the user has "bought" tools / techniques. I haven't implemented this idea yet as I'm still looking at more play elements that can make the game more engaging, as well as soliciting for more ideas. I am planning to release this under Creative Commons license but haven't decided on the exact license yet. Any more game play suggestions are welcome. UPDATE: This was posted in BoardGameGeek and there's now an active discussion thread there. http://www.boardgamegeek.com/article/4436694

  • rest and client rights integration, and backbone.js

    - by Francois
    I started to be more and more interested in the REST architecture style and client side development and I was thinking of using backbone.js on the client and a REST API (using ASP.NET Web API) for a little meeting management application. One of my requirements is that users with admin rights can edit meetings and other user can only see them. I was then wondering how to integrate the current user rights in the response for a given resource? My problem is beyond knowing if a user is authenticated or not, I want to know if I need to render the little 'edit' button next to the meeting (let's say I'm listing the current meetings in a grid) or not. Let's say I'm GETing /api/meetings and this is returning a list of meetings with their respective individual URI. How can I add if the user is able to edit this resource or not? This is an interesting passage from one of Roy's blog posts: A REST API should be entered with no prior knowledge beyond the initial URI (bookmark) and set of standardized media types that are appropriate for the intended audience (i.e., expected to be understood by any client that might use the API). From that point on, all application state transitions must be driven by client selection of server-provided choices that are present in the received representations or implied by the user’s manipulation of those representations It states that all transitions must be driven by the choices that are present in the representation. Does that mean that I can add an 'editURI' and a 'deleteURI' to each of the meeting i'm returning? if this information is there I can render the 'edit' button and if it's not there I just don't? What's the best practices on how to integrate the user's rights in the entity's representation? Or is this a super bad idea and another round trip is needed to fetch that information?

  • New Rails deployment half working...not sure why?

    - by Meltemi
    I'm in the final stages of going round trip through the entire Rails cycle: development - test - production (on an external server). I'm very close...but seeing some errors with the production version and don't know enough about Rails' "magic" to troubleshoot it yet... all seems well and I can load my app by going to www.mydomain.com/rails and it seems to work...I can interact with my app and create new objects in my database. However, when I go to www.mydomain.com/rails/ (difference is the trailing slash) i get a webpage that just says "Index from public" on it?!? I don't know where that's coming from? index.html is long removed from public. this may or may not be related to why I can't access, say, the first record in one of my classes by calling its controller like so: www.mydomain.com/rails/mycontroller/1 . and yes, there are records in the database. anyway, something's askew. it works fine on development box. but, only half working on production server. anyone know what might be causing this? this app is running on the server box (not development) Installed Passenger on server to serve app via Apache modified my httpd.conf with Passenger's stuff (headache but finally got it to respond) loaded schema into the production database: rake db:schema:load RAILS_ENV=production

  • Closures in Ruby

    - by Isaac Cambron
    I'm kind of new to Ruby and some of the closure logic has me a confused. Consider this code: array = [] for i in (1..5) array << lambda {j} end array.map{|f| f.call} => [5, 5, 5, 5, 5] This makes sense to me because i is bound outside the loop, so the same variable is captured by each trip through the loop. It also makes sense to me that using an each block can fix this: array = [] (1..5).each{|i| array << lambda {i}} array.map{|f| f.call} => [1, 2, 3, 4, 5] ...because i is now being declared separately for each time through. But now I get lost: why can't I also fix it by introducing an intermediate variable? array = [] for i in 1..5 j = i array << lambda {j} end array.map{|f| f.call} => [5, 5, 5, 5, 5] Because j is new each time through the loop, I'd think a different variable would be captured on each pass. For example, this is definitely how C# works, and how -- I think-- Lisp behaves with a let. But in Ruby not so much. It almost looks like = is aliasing the variable instead of copying the reference, but that's just speculation on my part. What's really happening?

  • ASP.NET AJAX weirdness

    - by LoveMeSomeCode
    Ok, I thought I understood these topics well, but I guess not, so hopefully someone here can clear this up. Page.IsAsync seems to be broken. It always returns false. But ScriptManager.IsInAsyncPostBack seems to work, sort of. It returns true during the round trip for controls inside UpdatePanels. This is good; I can tell if it's a partial postback or a regular one. ScriptManager.IsInAsyncPostBack returns false however for async Page Methods. Why is this? It's not a regular postback, I'm just calling a public static method on the page. It causes a problem because I also realized that if you have a control with AutoPostBack = false, it won't trigger a postback on it's own, but if it has an event handler on the page, that event handler code WILL run on the next postback, regardless of how the postback occurred, IF the value has changed. i.e. if I tweak a dropdown and then hit a button, that dropdown's handler code will fire. This is ok, except that it will also happen during Page Method calls, and I have no way to know the difference. Any thoughts?

  • How to generate lots of redundant ajax elements like checkboxes and pulldowns in Django?

    - by iJames
    Hello folks. I've been getting lots of answers from stackoverflow now that I'm in Django just be searching. Now I hope my question will also create some value for everybody. In choosing Django, I was hoping there was some similar mechanism to the way you can do partials in ROR. This was going to help me in two ways. One was in generating repeating indexed forms or form elements, and also in rendering only a piece of the page on the round trip. I've done a little bit of that by using taconite with a simple URL click but now I'm trying to get more advanced. This will focus on the form issue which boils down to how to iterate over a secondary object. If I have a list of photo instances, each of which has a couple of parameters, let's say a size and a quantity. I want to generate form elements for each photo instance separately. But then I have two lists I want to iterate on at the same time. Context: photos : Photo.objects.all() and forms = {} for photo in photos: forms[photo.id] = PhotoForm() In other words we've got a list of photo objects and a dict of forms based on the photo.id. Here's an abstraction of the template: {% for photo in photos %} {% include "photoview.html" %} {% comment %} So here I want to use the photo.id as an index to get the correct form. So that each photo has its own form. I would want to have a different action and each form field would be unique. Is that possible? How can I iterate on that? Thanks! {% endcomment %} Quantity: {{ oi.quantity }} {{ form.quantity }} Dimensions: {{ oi.size }} {{ form.size }} {% endfor %} What can I do about this simple case. And how can I make it where every control is automatically updating the server instead of using a form at all? Thanks! James

  • Travelling Visual Studio developers

    - by Graphain
    Hi, I am about to travel to Europe (I'm Australian but imagine this is a similar circumstance for US users and simply flipped for European users). However, there is the slim possibility I will need to do some Visual Studio work while I'm travelling. As I see it I have three options: Leave a desktop PC on at home, access remotely via net cafes. Carry a laptop with me on the trip, upload files as required using public wifi. Option 2 but instead buy cheap light netbook that is miraculously capable of running VS. Does anyone have any experience or advice to shed on any of these options? For reference, this existing post suggests that VS remotely for short distances is okay, but over longer distances could be more problematic. I've used VS via RDP to a US server before and it was pretty laggy but for small changes I could get by. Concerns I have that you may have some experience with: Weight of luggage (ideally like to travel light) Security of laptop (imagine it'll be too heavy to carry around all the time so have to leave it at hotel/hostel etc. and hope for the best) Security of data (don't want someone stealing RDP access to my home PC) Security of FTP (don't want someone stealing FTP passwords over wireless)

  • Entangled text boxes

    - by user38329
    Hi StackOverflow, A mere Windows textbox greatly surprised me today. I have two unrelated text boxes inside an application. I can type in either text box and switch the focus by clicking on them. Then happens some event X, which I can't describe here for reasons given below. After this event happens, the two text boxes become "entangled" in an almost quantum way. Say, text box A was focused before X happened. When I click text box B to type in some text, the new text appears in text box A, whereas the blinking cursor happily moves along in text box B through the void, as if the text were there. No amount of clicking on either text boxes can resolve this. The cursor will always remain in B, whereas the text will always go to A. Message spying reveals that after the event X, the text boxes lose the ability to lose or gain focus. When I click on B, WM_LOSE_FOCUS does not come to A, and WM_SET_FOCUS does not come to B. (The rectangles and visibility of the boxes are OK.) The same thing happens in Windows XP and Windows 7. Now, event X: it's a big event in a third-party UI library which I cannot reverse-engineer in a timely manner. (Namely, docking a pane in wxAUI.) I am sure that this behavior is the result of incorrect WinAPI calls to the text boxes (garbage in - garbage out). I would like to know what could possibly cause such "textbox trip" to know where to start looking for the bug. Thanks!

  • To OpenID or not to OpenID? Is it worth it?

    - by Eloff
    Does OpenID improve the user experience? Edit Not to detract from the other comments, but I got one really good reply below that outlined 3 advantages of OpenID in a rational bottom line kind of way. I've also heard some whisperings in other comments that you can get access to some details on the user through OpenID (name? email? what?) and that using that it might even be able to simplify the registration process by not needing to gather as much information. Things that definitely need to be gathered in a checkout process: Full name Email (I'm pretty sure I'll have to ask for these myself) Billing address Shipping address Credit card info There may be a few other things that are interesting from a marketing point of view, but I wouldn't ask the user to manually enter anything not absolutely required during the checkout process. So what's possible in this regard? /Edit (You may have noticed stackoverflow uses OpenID) It seems to me it is easier and faster for the user to simply enter a username and password in a signup form they have to go through anyway. I mean you don't avoid entering a username and password either with OpenID. But you avoid the confusion of choosing a OpenID provider, and the trip out to and back from and external site. With Microsoft making Live ID an OpenID provider (More Info), bringing on several hundred million additional accounts to those provided by Google, Yahoo, and others, this question is more important than ever. I have to require new customers to sign up during the checkout process, and it is absolutely critical that the experience be as easy and smooth as possible, every little bit harder it becomes translates into lost sales. No geek factor outweighs cold hard cash at the end of the day :) OpenID seems like a nice idea, but the implementation is of questionable value. What are the advantages of OpenID and is it really worth it in my scenario described above?

  • Struts 2 security

    - by Dewfy
    Does Struts 2 has complete solution for simple login task? I have simple declaration in struts.xml: <package namespace="/protected" name="manager" extends="struts-default" > <interceptors> <interceptor-stack name="secure"> <interceptor-ref name="roles"> <param name="allowedRoles">registered</param> </interceptor-ref> </interceptor-stack> </interceptors> <default-action-ref name="pindex"/> <action name="pindex" > <interceptor-ref name="completeStack"/> <interceptor-ref name="secure"/> <result>protected/index.html</result> </action> </package> Accessing to this resource shows only (Forbidden 403). So what should I do on the next step to: Add login page (standart Tomcat declaration on web.xml with <login-config> not works) ? Provide security round trip. Do I need write my own servlet or exists struts2 solutions? Thanks in advance!

  • Why does an authorized OAuth request token need to be exchanged for an access token?

    - by Joe Shaw
    I'm wondering what the reasons are for OAuth to require a round-trip to the data provider to exchange an authorized request token for an access token. My understanding of the OAuth workflow is: Requesting site (consumer) gets a request token from the data provider site (service provider). Requesting site asks the data provider site to authenticate the user, passing in a callback. Once the user has been authenticated and authorized the requesting site, the user is directed back to the requesting site (consumer) via the callback provided which passes back the now-authorized request token and a verification code. The requesting site exchanges the request token for an access token. The requesting site uses the access token to get data from the data provider site. Assuming I got that right, why couldn't the callback simply provide the access token to the requesting site directly in step 3, eliminating step 4? Why is the request to exchange the request token for the access token necessary? Does it exist solely for consumers that require users to enter the verification code manually, with the thought that it would be shorter and simpler than the access token itself?

  • Localisable Resources: how can (should one?!) wrap a UI layer source as a BL layer service?

    - by Ciel
    A service that returns localised strings could be wrapped in a service, so that it could be used both locally (eg in an MVC app) and remotely (eg possibly Silverlight). But...if sticking with the standard practice of creating resources in the UI assembly, that would in effect make a lower layer (BL/Services) have to have a ref on a higher layer (UI)...a definite no-no. And whereas a lot of AppWide resources (eg: AppName, OK, Cancel, etc.) could be defined in a Common cross-cutting assembly, and the BL/ResourceSerouce could ref and wrap those, that doesn't work in a a Modular App, where the Core app should have no binding to/knowledge of any Module. One solution could be to have each module, once mounted in mem, 'register' their Resource files with the service, who would then return it to the service (rather a long round trip, but at least consistent as a service, and potentially resources/images could be shared with other resources). Secondly, that may work in a web app...but not sure how that pattern could be extended to a Silverlight modular app (the round tripping becomes prohibitive). ie...what are best practices for allowing Resources to be to be defined by the UI designer, in a higher level, but served from the lower BL layer, as a Service? Or is there a better way of understanding/solving the problem?
