• cookieless sessions with ajax

  - by thezver

  ok, i know you get sick from this subject. me too :( I've been developing a quite "big application" with PHP & kohana framework past 2 years, somewhat-successfully using my framework's authentication mechanism. but within this time, and as the app grown, many concerning state-preservation issues arisen. main problems are that cookie-driven sessions: can't be used for web-service access ( at least it's really not nice to do so.. ) in many cases problematic with mobile access don't allow multiple simultaneous apps on same browser ( can be resolved by hard trickery, but still.. ) requires many configurations and mess to work 100% right, and that's without the --browser issues ( disabled cookies, old browsers bugs & vulnerabilities etc ) many other session flaws stated in this old thread : http://lists.nyphp.org/pipermail/talk/2006-December/020358.html After a really long research, and without any good library/on-hand-solution to feet my needs, i came up with a custom solution to majority of those problems . Basically, i'ts about emulating sessions with ajax calls, with additional security/performance measures: state preserved by interchanging SID(+hash) with client on ajax calls. state data saved in memcache(or equivalent), indexed by SID security achieved by: appending unpredictible hash to SID egenerating hash on each request & validating it validating fingerprint of client on each request ( referrer,os,browser etc) (*)condition: ajax calls are not simultaneous, to prevent race-condition with session token. (hopefully Ext-Direct solves that for me) From the first glance that supposed to be not-less-secure than equivalent cookie-driven implementation, and at the same time it's simple, maintainable, and resolves all the cookies flaws.. But i'm really concerned because i often hear the rule "don't try to implement custom security solutions". I will really appreciate any serious feedback about my method, and any alternatives. also, any tip about how to preserve state on page-refresh without cookies would be great :) but thats small technical prob. Sorry if i overlooked some similar post.. there are billions of them about sessions . Big thanks in advance ( and for reading until here ! ).

• "Access is denied" JavaScript error when trying to access the document object of a programmatically-

  - by Bungle

  I have project in which I need to create an <iframe> element using JavaScript and append it to the DOM. After that, I need to insert some content into the <iframe>. It's a widget that will be embedded in third-party websites. I don't set the "src" attribute of the <iframe> since I don't want to load a page; rather, it is used to isolate/sandbox the content that I insert into it so that I don't run into CSS or JavaScript conflicts with the parent page. I'm using JSONP to load some HTML content from a server and insert it in this <iframe>. I have this working fine, with one serious exception - if the document.domain property is set in the parent page (which it may be in certain environments in which this widget is deployed), Internet Explorer (probably all versions, but I've confirmed in 6, 7, and 8) gives me an "Access is denied" error when I try to access the document object of this <iframe> I've created. It doesn't happen in any other browsers I've tested in (all major modern ones). This makes some sense, since I'm aware that Internet Explorer requires you to set the document.domain of all windows/frames that will communicate with each other to the same value. However, I'm not aware of any way to set this value on a document that I can't access. Is anyone aware of a way to do this - somehow set the document.domain property of this dynamically created <iframe>? Or am I not looking at it from the right angle - is there another way to achieve what I'm going for without running into this problem? I do need to use an <iframe> in any case, as the isolated/sandboxed window is crucial to the functionality of this widget. Here's my test code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Document.domain Test</title> <script type="text/javascript"> document.domain = 'onespot.com'; // set the page's document.domain </script> </head> <body> <p>This is a paragraph above the &lt;iframe&gt;.</p> <div id="placeholder"></div> <p>This is a paragraph below the &lt;iframe&gt;.</p> <script type="text/javascript"> var iframe = document.createElement('iframe'), doc; // create <iframe> element document.getElementById('placeholder').appendChild(iframe); // append <iframe> element to the placeholder element setTimeout(function() { // set a timeout to give browsers a chance to recognize the <iframe> doc = iframe.contentWindow || iframe.contentDocument; // get a handle on the <iframe> document alert(doc); if (doc.document) { // HEREIN LIES THE PROBLEM doc = doc.document; } doc.body.innerHTML = '<h1>Hello!</h1>'; // add an element }, 10); </script> </body> </html> I've hosted it at: http://troy.onespot.com/static/access_denied.html As you'll see if you load this page in IE, at the point that I call alert(), I do have a handle on the window object of the <iframe>; I just can't get any deeper, into its document object. Thanks very much for any help or suggestions! I'll be indebted to whomever can help me find a solution to this.

• Perf: Viewing thousands of images in Silverlight 3 on a 3D Wall

  - by Bob Holland

  I currently work on a very cool Silverlight app that displays photos in a 3D wall space like the Wall3D demo that is thrown in with Blend 3. The problem I am currently facing is performance. The app works like this: As you scroll right or left the 3d photo wall rotates As each movement is made, the next column of photos are downloaded, decoded into a BitmapImage and thrown into a 3D Wall Node. As you can imagine users (if you let them) will want to flip through the photos really quickly, but the problem I have is I cannot display the photos quick enough. In most cases it's a beautiful app that works really well, but when an album contains over 300 photos, you can imagine the sort of memory taken up by all the BitmapImage classes and how moving the slider can jump from photo 20 to photo 120 in a second. Of course we have algorithms in place to not download every photo in between, but I still can't work out a fast way to get the photos displayed. It may be a case that we need to throw away the 'great for show' 3D wall and go to a flat DeepZoom like wall like the Playboy archive one that Vertigo did. Still not sure, let me know your thoughts. P.S. We are using Kit3D for all the 3D work, it's using PerspectiveCamera, Model3DGroup, ModelVisual3D, RotateTransform3D & TranslateTransform3D. Cheers, Bob.

• VB .NET DirectCast and Type Reflection

  - by msarchet

  The application that I am working on has a generic Parent Form called RSChild, that is used to perform some operations depending on whether or not the control that is contained within it is in a MdiTabManager or inside of its own modal form. Then the actual User Controls contained within Inherit from a Interface Called ObjectEdit (Objects that we allow to be edited). At a point in my code I am doing this. Public Function doesTabExist(ByVal id As Integer, ByVal recordType As Enums.eRecordType) As Boolean Dim alikePages As Object = (From tabs In DirectCast(Control.FromHandle(MainForm.SharedHandle), MainForm).XtraTabbedMdiManager1.Pages Where DirectCast(tabs.MdiChild, RSChild).RSObject.RecordType = recordType Select tabs) For Each page As DevExpress.XtraTabbedMdi.XtraMdiTabPage In alikePages Select Case recordType Case Enums.eRecordType.Doctor If id = DirectCast(castTabPageToRSChild(page).RSObject, UI.Doctor).ID Then pageToActive(page) Return True End If 'rest of the cases so the case block is repeated 10 times' End Function And my castTabPageToRSChild(page) is a lambda function as Such Dim castTabPageToRSChild As Func(Of DevExpress.XtraTabbedMdi.XtraMdiTabPage, RSChild) = Function(page) DirectCast(page.MdiChild, RSChild) So my Question is, I have about 10 case statements, all because I can't seem to find a way to use reflection to get the underlying Type of the RSObject Object. So I have the whole If block repeated over and over. I tried doing castTabPageToRSChild(page)RSObject.GetType and using that in the DirectCast and I also tried creating another object that was separate from that and doing the same thing. My code works as intended I'm just trying to see if there is a manner in which I didn't have a lot of replicated code. My vision would be to do something like For Each page As XtraMdiTabPage In alikePages If id = DirectCast(castTabPageToRSchild(page).RSObject, TypeOfThatObject).Id Then Return True Next However I have a feeling this is not possible due to the behavior of DirectCast.

• Redirect from URL with QueryString to the same URL without QueryString

  - by Slauma

  I have a page request with a QueryString, say http://www.xyz.net/Orders.aspx?OrderID=1. The page is displayed in a browser. Now there is an asp:LinkButton on the page which should enable the user to open the page without the QueryString (as if he had entered http://www.xyz.net/Orders.aspx directly in the browser's address bar). I had two ideas: 1) Use the PostBackUrl attribute of the LinkButton: <asp:LinkButton ID="LinkButton1" runat="server" Text="Select" PostBackUrl="~/Orders.aspx" /> 2) Use "RedirectUrl" in an event handler: <asp:LinkButton ID="LinkButton1" runat="server" Text="Select" OnClick="LinkButton1_Click" /> ...and... protected void LinkButton1_Click(object sender, EventArgs e) { Response.Redirect("~/Orders.aspx"); } In both cases the browser's address bar shows http://www.xyz.net/Orders.aspx without the QueryString, as I like to have it. But in the first case the page does not change at all. But it should, because I'm evaluating the QueryString in code-behind and control the appearance of the page depending on whether a QueryString exists or not. The second option works as intended. If I am not wrong the second option requires an additional roundtrip: Browser sends request to server Event handler on server side sends Redirect URL to browser Browser sends again request to the server, but with the new URL Server sends new requested page to browser Is this correct at all? Whereas the first option omits the first two steps in the list above, thus saving the additional roundtrip and resulting in: Browser sends request to the server, but with the new URL (the PostbackURL specified in the LinkButton) Server sends new requested page to browser But, as said, the result isn't the same. I'm sure my try to explain the differences between the two options is wrong somewhere. But I don't know where exactly. Can someone explain what's really the difference? Do I really need this second roundtrip of option (2) to achieve what I want? Thanks in advance!

• code review: Is it subjective or objective(quantifiable) ?

  - by Ram

  I am putting together some guidelines for code reviews. We do not have one formal process yet, and trying to formalize it. And our team is geographically distributed We are using TFS for source control (used it for tasks/bug tracking/project management as well, but migrated that to JIRA) with VS2008 for development. What are the things you look for when doing a code review ? These are the things I came up with Enforce FXCop rules (we are a Microsoft shop) Check for performance (any tools ?) and security (thinking about using OWASP- code crawler) and thread safety Adhere to naming conventions The code should cover edge cases and boundaries conditions Should handle exceptions correctly (do not swallow exceptions) Check if the functionality is duplicated elsewhere method body should be small(20-30 lines) , and methods should do one thing and one thing only (no side effects/ avoid temporal coupling -) Do not pass/return nulls in methods Avoid dead code Document public and protected methods/properties/variables What other things do you generally look for ? I am trying to see if we can quantify the review process (it would produce identical output when reviewed by different persons) Example: Saying "the method body should be no longer than 20-30 lines of code" as opposed to saying "the method body should be small" Or is code review very subjective ( and would differ from one reviewer to another ) ? The objective is to have a marking system (say -1 point for each FXCop rule violation,-2 points for not following naming conventions,2 point for refactoring etc) so that developers would be more careful when they check in their code.This way, we can identify developers who are consistently writing good/bad code.The goal is to have the reviewer spend about 30 minutes max, to do a review (I know this is subjective, considering the fact that the changeset/revision might include multiple files/huge changes to the existing architecture etc , but you get the general idea, the reviewer should not spend days reviewing someone's code) What other objective/quantifiable system do you follow to identify good/bad code written by developers?

• Silverlight async calls and anonymous methods....

  - by JLewis

  I know there are a couple of debates on this kind of thing.... At any rate, I have several cases where I need to populate combobox items based on enumerations returned from the WCF service. In an effort to keep code clean, I started this approach. After looking into it more, I don't think the this works as well is initially thought... I am throwing this out to get recommendations/advice/code snippets on how you would do this or how you currently do this. I may be forced to have a seperate, non anonymous method, procedure. I hate doing this for something like this but at the moment, don't see it working another way... EventHandler<GetEnumerationsForTypeCompletedEventArgs> ev = null; ev = delegate(object eventSender, GetEnumerationsForTypeCompletedEventArgs eventArgs) { if (eventArgs.Error == null) { //comboBox.ItemsSource = eventArgs.Result; // populate combox for display purposes (for now) foreach (Enumeration e in eventArgs.Result) { ComboBoxItem cbi = new ComboBoxItem(); cbi.Content = e.EnumerationValueDisplayed; comboBox.Items.Add(cbi); } // remove event so we don't keep adding new events each time we need an enumeration proxy.GetEnumerationsForTypeCompleted -= ev; } }; proxy.GetEnumerationsForTypeCompleted += ev; proxy.GetEnumerationsForTypeAsync(sEnumerationType); Basically in this example we use ev to hold the anonymous method so we can then use ev from within the method to remove it from the events once called. This prevents this method from getting called more than one time. I suspect that the comboBox local var declared before this call, but within the same method, is not always the combobox originally intended but can't really verify that yet. I may add a tag to it to do some tests and populating to verify. Sorry if this is not clear. I can elaborate more if needed. Thanks Jeff

• Wpf: Why is WriteableBitmap getting slower?

  - by fritz

  There is a simple MSDN example about WriteableBitmap. It shows how to draw a freehand line with the cursor by just updating one pixel when the mouse is pressed and is moving over a WPF -Image Control. writeableBitmap.Lock(); (...set the writeableBitmap.BackBuffers pixel value...) writeableBitmap.AddDirtyRect(new Int32Rect(column, row, 1, 1)); writeableBitmap.Unlock(); Now I'm trying to understand the following behaviour when moving the mouse pointer very fast: If the image/bitmap size is relatively small e.g. 800:600 pixel, then the last drawn pixel is always "synchronized" with the mouse pointers position, i.e. there is no delay, very fast reaction on mouse movements. But if the bitmap gets larger e.g. 1300:1050 pixel, you can notice a delay, the last drawn pixel always appear a bit delayed behind the moving mouse pointer. So as in both cases only one pixel gets updated with "AddDirtyRect", the reaction speed should be independent from the bitmap size!? But it seems that Writeablebitmap gets slower when it's size gets larger. Or does the whole bitmap somehow get transferred to the graphic device on every writeableBitmap.Unlock(); call , and not only the rectangle area speficied in the AddDirtyRect method? fritz

• What are common anti-patterns when using VBA

  - by Ahmad

  I have being coding a lot in VBA lately (maintenance and new code), specifically with regards to Excel automation etc. = macros. Typically most of this has revolved around copy/paste, send some emails, import some files etc. but eventually just ends up as a Big ball of mud As a person who values clean code, I find it very difficult to produce 'decent' code when using VBA. I think that in most cases, this is a direct result of the macro-recorder. Very helpful to get you started, but most times, there are one too many lines of code that achieve the end result. Edit: The code from the macro-recorder is used as a base to get started, but is not used in its entirety in the end result I have already created a common addin that has my commonly used subroutines and some utility classes in an early attempt to enforce some DRYness - so this I think is a step in the right direction. But I feel as if it's a constant square peg, round hole situation. The wiki has an extensive list of common anti-patterns and what scared me the most was how many I have implemented in one way or another. The question Now considering, that my mindset is OO design, what some common anti-patterns and the possible solutions when designing a solution (think of this - how would designing a solution using Excel and VBA be different from say a .net/java/php/.../ etc solution) ; and when doing common tasks like copying data, emailing, data importing, file operations... etc An anti-pattern as defined by Wikipedia is: In software engineering, an anti-pattern (or antipattern) is a pattern that may be commonly used but is ineffective and/or counterproductive in practice

• Need advice or pointers on Release Management Strategies

  - by Murray

  I look after an internal web based (Java, JSP, Mediasurface, etc.) system that is in constant use (24/5). Users raise tickets for enhancements, bug fixes and other business changes. These issues are signed off individually and assigned to one of three or four developers. Once the issue is complete it is built and the code only committed to SVN. The changed files (templates, html, classes, jsp) are then copied to a dev server and committed to a different repository from where they are checked out to the UAT server for testing. (this often requires the Tomcat service to be restarted and occasionally the Mediasurface service as well). The users then test and either reject or approve the release. If approved the edited files are checked out to the Live server and the same process as with UAT undertaken. If rejected the developer makes the relevant changes and starts the release process again. This is all done manually without much control. Where different developers are working on similar files, changes sometimes get overwritten by builds done on out of sync code in other cases changes in UAT are moved to live in error as they are mixed up in files associated with a signed off release. I would like to move this to a more controlled and automated process where all source code and output files are held in SVN and releases to Dev, UAT and Live managed by a CI system (We have TeamCity in house for our .NET applications). My question is on how to manage the releases of multiple changes where some will be signed off and moved on and others rejected and returned to the developer. The changes may be on overlapping files and simply merging each release in to a Release Branch means that the rejected changes would have to be backed out of the branch. Is there a way to manage this using SVN and CI or will I simply have to live with the current system.

• how do I access XHR responseBody from Javascript?

  - by Cheeso

  I've got a web page that uses XMLHttpRequest to download a binary resource. Because it's binary I'm trying to use xhr.responseBody to access the bytes. I've seen a few posts suggesting that it's impossible to access the bytes directly from Javascript. This sounds crazy to me. Weirdly, xhr.responseBody is accessible from VBScript, so the suggestion is that I must define a method in VBScript in the webpage, and then call that method from Javascript. See jsdap for one example. var IE_HACK = (/msie/i.test(navigator.userAgent) && !/opera/i.test(navigator.userAgent)); if (IE_HACK) document.write('<script type="text/vbscript">\n\ Function BinaryToArray(Binary)\n\ Dim i\n\ ReDim byteArray(LenB(Binary))\n\ For i = 1 To LenB(Binary)\n\ byteArray(i-1) = AscB(MidB(Binary, i, 1))\n\ Next\n\ BinaryToArray = byteArray\n\ End Function\n\ </script>'); var xml = (window.XMLHttpRequest) ? new XMLHttpRequest() // Mozilla/Safari/IE7+ : (window.ActiveXObject) ? new ActiveXObject("MSXML2.XMLHTTP") // IE6 : null; // Commodore 64? xml.open("GET", url, true); if (xml.overrideMimeType) { xml.overrideMimeType('text/plain; charset=x-user-defined'); } else { xml.setRequestHeader('Accept-Charset', 'x-user-defined'); } xml.onreadystatechange = function() { if (xml.readyState == 4) { if (!binary) { callback(xml.responseText); } else if (IE_HACK) { // call a VBScript method to copy every single byte callback(BinaryToArray(xml.responseBody).toArray()); } else { callback(getBuffer(xml.responseText)); } } }; xml.send(''); Is this really true? The best way? copying every byte? For a large binary stream that's not gonna be very efficient. There is also a possible technique using ADODB.Stream, which is a COM equivalent of a MemoryStream. See here for an example. It does not require VBScript but does require a separate COM object. if (typeof (ActiveXObject) != "undefined" && typeof (httpRequest.responseBody) != "undefined") { // Convert httpRequest.responseBody byte stream to shift_jis encoded string var stream = new ActiveXObject("ADODB.Stream"); stream.Type = 1; // adTypeBinary stream.Open (); stream.Write (httpRequest.responseBody); stream.Position = 0; stream.Type = 1; // adTypeBinary; stream.Read.... /// ???? what here } I don't think that's gonna work - ADODB.Stream is disabled on most machines these days. In The IE8 developer tools - the IE equivalent of Firebug - I can see the responseBody is an array of bytes and I can even see the bytes themselves. The data is right there. I don't understand why I can't get to it. Is it possible for me to read it with responseText? hints? (other than defining a VBScript method)

• codingbat wordEnds using regex

  - by polygenelubricants

  I'm trying to solve wordEnds from codingbat.com using regex. This is the simplest as I can make it with my current knowledge of regex: public String wordEnds(String str, String word) { return str.replaceAll( String.format( ".*?(?=%s)(?<=(.|^))%1$s(?=(.|$))|.+", java.util.regex.Pattern.quote(word) ), "$1$2" ); } String.format is used to inject word into the pattern for both readability and convenience (it's injected twice). Pattern.quote isn't necessary to pass their tests, but I think it's required for a proper regex-based solution. The regex has two major parts: If after matching as few characters as possible ".*?", word can still be found "(?=%s)", then lookbehind to capture any character immediately preceding it "(?<=(.|^))", match word "%1$s" and lookforward to capture any character following it "(?=(.|$))". The initial "if" test ensures that the atomic lookbehind captures only if there's a word Using lookahead to capture the following character doesn't consume it, so it can be used as part of further matching Otherwise match what's left "|.+" Groups 1 and 2 would capture empty strings I think this works in all cases, but it's obviously quite complex. I'm just wondering if others can suggest a simpler regex to do this. Note: I'm not looking for a solution using indexOf and a loop. I want a regex-based replaceAll solution. I also need a working solution that I can just copy-paste into codingbat and passes.

• WCF net.tcp bindings, message formats and security questions

  - by RemotecUk

  Hi, sorry for the stupid questions but there are just some things about WCF I cant get my head around. Would be greatful for some advice on the following.... At a very basic level is it correct that WCF uses either Binary (Net.Tcp), HTTP or MSMQ to transfer my message on the wire? However is it true that in all cases, regardless of how the data is transferred the message itself in in the SOAP format with headers and a body? So its a sort of XML message that is transmitted in either HTTP/S or in a binary format. Is Net.Tcp a good choice for my client server app - its similar to a messenger app in that the clients are all remote users on the other side of the firewall to my server. Most things I am reading are telling to use WS* and HTTP. Is Net.Tcp secured by standard and without certificates? - that is - people cannot listen on the wire and decode the data thats going to and from. Is it possible to send a username and password using net.tcp and without an installed certificate? If so I presume I can hook this up to my membership provider and authenticate access to each method on my service contract implementation. I presume that with username and password security, the proxy is initialised with the username and password and that this information is is sent with every request. Then my membership provider will be invoked for each method call and do whatever it needs to do to get the authorisation for the method. Sorry for the dump of questions but would be great to know if Im thinking the right way about how WCF works. Thanks.

• 5x5 matrix multiplication in C

  - by Rick

  I am stuck on this problem in my homework. I've made it this far and am sure the problem is in my three for loops. The question directly says to use 3 for loops so I know this is probably just a logic error. #include<stdio.h> void matMult(int A[][5],int B[][5],int C[][5]); int printMat_5x5(int A[5][5]); int main() { int A[5][5] = {{1,2,3,4,6}, {6,1,5,3,8}, {2,6,4,9,9}, {1,3,8,3,4}, {5,7,8,2,5}}; int B[5][5] = {{3,5,0,8,7}, {2,2,4,8,3}, {0,2,5,1,2}, {1,4,0,5,1}, {3,4,8,2,3}}; int C[5][5] = {0}; matMult(A,B,C); printMat_5x5(A); printf("\n"); printMat_5x5(B); printf("\n"); printMat_5x5(C); return 0; } void matMult(int A[][5], int B[][5], int C[][5]) { int i; int j; int k; for(i = 0; i <= 2; i++) { for(j = 0; j <= 4; j++) { for(k = 0; k <= 3; k++) { C[i][j] += A[i][k] * B[k][j]; } } } } int printMat_5x5(int A[5][5]){ int i; int j; for (i = 0;i < 5;i++) { for(j = 0;j < 5;j++) { printf("%2d",A[i][j]); } printf("\n"); } } EDIT: Here is the question, sorry for not posting it the first time. (2) Write a C function to multiply two five by five matrices. The prototype should read void matMult(int a[][5],int b[][5],int c[][5]); The resulting matrix product (a times b) is returned in the two dimensional array c (the third parameter of the function). Program your solution using three nested for loops (each generating the counter values 0, 1, 2, 3, 4) That is, DO NOT code specific formulas for the 5 by 5 case in the problem, but make your code general so it can be easily changed to compute the product of larger square matrices. Write a main program to test your function using the arrays a: 1 2 3 4 6 6 1 5 3 8 2 6 4 9 9 1 3 8 3 4 5 7 8 2 5 b: 3 5 0 8 7 2 2 4 8 3 0 2 5 1 2 1 4 0 5 1 3 4 8 2 3 Print your matrices in a neat format using a C function created for printing five by five matrices. Print all three matrices. Generate your test arrays in your main program using the C array initialization feature. enter code here

• Securing Web Service communication with SSL using CXF

  - by reef

  Hi all, I am trying to secure communications via SSL/TLS for one of our Web Service using CXF 2.2.5. I am wondering how to update client and server Spring configuration file to activate this feature. I found some information on CXF's website (CXF Wiki) for the client configuration, here is the given example: <http:conduit name="{http://apache.org/hello_world}HelloWorld.http-conduit"> <http:tlsClientParameters> <sec:keyManagers keyPassword="password"> <sec:keyStore type="JKS" password="password" file="src/test/java/org/apache/cxf/systest/http/resources/Morpit.jks"/> </sec:keyManagers> <sec:trustManagers> <sec:keyStore type="JKS" password="password" file="src/test/java/org/apache/cxf/systest/http/resources/Truststore.jks"/> </sec:trustManagers> <sec:cipherSuitesFilter> <!-- these filters ensure that a ciphersuite with export-suitable or null encryption is used, but exclude anonymous Diffie-Hellman key change as this is vulnerable to man-in-the-middle attacks --> <sec:include>.*_EXPORT_.*</sec:include> <sec:include>.*_EXPORT1024_.*</sec:include> <sec:include>.*_WITH_DES_.*</sec:include> <sec:include>.*_WITH_NULL_.*</sec:include> <sec:exclude>.*_DH_anon_.*</sec:exclude> </sec:cipherSuitesFilter> </http:tlsClientParameters> <http:authorization> <sec:UserName>Betty</sec:UserName> <sec:Password>password</sec:Password> </http:authorization> <http:client AutoRedirect="true" Connection="Keep-Alive"/> </http:conduit> Concerning this configuration, the Concerning the server side configuration I am unable to launch the server properly, here is the configuration I have: <http:destination name="{urn:ihe:iti:xds-b:2007}DocumentRepository_Port_Soap12.http-destination"> </http:destination> <httpj:engine-factory> <httpj:engine port="9043"> <httpj:tlsServerParameters> <sec:keyManagers keyPassword="changeit"> <sec:keyStore type="JKS" password="changeit" file="security/keystore.jks" /> </sec:keyManagers> <sec:trustManagers> <sec:keyStore type="JKS" password="changeit" file="security/cacerts.jks" /> </sec:trustManagers> <sec:cipherSuitesFilter> <!-- these filters ensure that a ciphersuite with export-suitable or null encryption is used, but exclude anonymous Diffie-Hellman key change as this is vulnerable to man-in-the-middle attacks --> <sec:include>.*_EXPORT_.*</sec:include> <sec:include>.*_EXPORT1024_.*</sec:include> <sec:include>.*_WITH_DES_.*</sec:include> <sec:include>.*_WITH_NULL_.*</sec:include> <sec:exclude>.*_DH_anon_.*</sec:exclude> </sec:cipherSuitesFilter> <sec:clientAuthentication want="true" required="true" /> </httpj:tlsServerParameters> </httpj:engine> </httpj:engine-factory> But when I run my application server (JOnas) with this configuration I have the following error message: Line 20 in XML document from ServletContext resource [/WEB-INF/beans.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'httpj:engine-factory'. Do you guys know how to solve this issue? Thanks in advance,

• InvalidOperationException (Lambda parameter not in scope) when trying to Compile a Lambda Expression

  - by Moshe Levi

  Hello, I'm writing an Expression Parser to make my API more refactor friendly and less error prone. basicaly, I want the user to write code like that: repository.Get(entity => entity.Id == 10); instead of: repository.Get<Entity>("Id", 10); Extracting the member name from the left side of the binary expression was straight forward. The problems began when I tried to extract the value from the right side of the expression. The above snippet demonstrates the simplest possible case which involves a constant value but it can be much more complex involving closures and what not. After playing with that for some time I gave up on trying to cover all the possible cases myself and decided to use the framework to do all the heavy lifting for me by compiling and executing the right side of the expression. the relevant part of the code looks like that: public static KeyValuePair<string, object> Parse<T>(Expression<Func<T, bool>> expression) { var binaryExpression = (BinaryExpression)expression.Body; string memberName = ParseMemberName(binaryExpression.Left); object value = ParseValue(binaryExpression.Right); return new KeyValuePair<string, object>(memberName, value); } private static object ParseValue(Expression expression) { Expression conversionExpression = Expression.Convert(expression, typeof(object)); var lambdaExpression = Expression.Lambda<Func<object>>(conversionExpression); Func<object> accessor = lambdaExpression.Compile(); return accessor(); } Now, I get an InvalidOperationException (Lambda parameter not in scope) in the Compile line. when I googled for the solution I came up with similar questions that involved building an expression by hand and not supplying all the pieces, or trying to rely on parameters having the same name and not the same reference. I don't think that this is the case here because I'm reusing the given expression. I would appreciate if someone will give me some pointers on this. Thank you.

• How does the recursion here work?

  - by David

  code 1: public static int fibonacci (int n){ if (n == 0 || n == 1) { return 1; } else { return fibonacci (n-1) + fibonacci (n-2); } } how can you use fibonacci if you haven't gotten done explaining what it is yet? I've been able to understand using recursion in other cases like this: code two: class two { public static void two (int n) { if (n>0) { System.out.println (n) ; two (n-1) ; } else { return ; } } public static void main (String[] arg) { two (12) ; } } In the case of code 2 though n will eventualy reach a point at which it doesnt satisfy n0 and the method will stop calling itself recursivly. in the case of code 2 though i don't see how it would be able to get itself from 1 if n=1 was the starting point to 2 and 3 and 5 and so on. Also i don't see how the line `return fibonacci (n-1) + fibonacci (n-2) would work since fibbonacci n-2 has to contain in some sense fibonacci n-1 in order to wrok but it isn't there yet. I know my question is worded poorly but looking at this is making my mind explode. the book i'm looking at says it will work. how does it work? `

• Zend_Translate scan translation files

  - by nute

  I've trying to use Zend_Translate from Zend Framework I am using "POEdit" to generate "gettext" translation files. My files are under /www/mysite.com/webapps/includes/locale (this path is in my include path). I have: pictures.en.mo pictures.en.po (I plan on having pictures.es.mo soon) It all works fine if I manually do addTranslation() for each file. However I want to use the automatic file scanning method. I tried both of those: <?php /*Localization*/ require_once 'Zend/Translate.php'; require_once 'Zend/Locale.php'; define('LOCALE','/www/mysite.com/webapps/includes/locale'); if(!empty($_GET['locale'])){ $locale = new Zend_Locale($_GET['locale']); } else{ $locale = new Zend_Locale(); } $translate = new Zend_Translate('gettext', LOCALE, null, array('scan' => Zend_Translate::LOCALE_FILENAME)); if ( $translate->isAvailable( $locale->getLanguage() ) ){ $translate->setLocale($locale); } else{ $translate->setLocale('en'); } And this: <?php /*Localization*/ require_once 'Zend/Translate.php'; require_once 'Zend/Locale.php'; define('LOCALE','/www/mysite.com/webapps/includes/locale'); if(!empty($_GET['locale'])){ $locale = new Zend_Locale($_GET['locale']); } else{ $locale = new Zend_Locale(); } $translate = new Zend_Translate('gettext', LOCALE); if ( $translate->isAvailable( $locale->getLanguage() ) ){ $translate->setLocale($locale); } else{ $translate->setLocale('en'); } In both cases, I get a Notice: No translation for the language 'en' available. in /www/mysite.com/webapps/includes/Zend/Translate/Adapter.php on line 411 It also worked if I tried to do directory scanning.

• HtmlAgilityPack giving problems with malformed html

  - by Kapil

  I want to extract meaningful text out of an html document and I was using html-agility-pack for the same. Here is my code: string convertedContent = HttpUtility.HtmlDecode(ConvertHtml(HtmlAgilityPack.HtmlEntity.DeEntitize(htmlAsString))); ConvertHtml: public string ConvertHtml(string html) { HtmlDocument doc = new HtmlDocument(); doc.LoadHtml(html); StringWriter sw = new StringWriter(); ConvertTo(doc.DocumentNode, sw); sw.Flush(); return sw.ToString(); } ConvertTo: public void ConvertTo(HtmlAgilityPack.HtmlNode node, TextWriter outText) { string html; switch (node.NodeType) { case HtmlAgilityPack.HtmlNodeType.Comment: // don't output comments break; case HtmlAgilityPack.HtmlNodeType.Document: foreach (HtmlNode subnode in node.ChildNodes) { ConvertTo(subnode, outText); } break; case HtmlAgilityPack.HtmlNodeType.Text: // script and style must not be output string parentName = node.ParentNode.Name; if ((parentName == "script") || (parentName == "style")) break; // get text html = ((HtmlTextNode)node).Text; // is it in fact a special closing node output as text? if (HtmlNode.IsOverlappedClosingElement(html)) break; // check the text is meaningful and not a bunch of whitespaces if (html.Trim().Length > 0) { outText.Write(HtmlEntity.DeEntitize(html) + " "); } break; case HtmlAgilityPack.HtmlNodeType.Element: switch (node.Name) { case "p": // treat paragraphs as crlf outText.Write("\r\n"); break; } if (node.HasChildNodes) { foreach (HtmlNode subnode in node.ChildNodes) { ConvertTo(subnode, outText); } } break; } } Now in some cases when the html pages are malformed (for example the following page - http://rareseeds.com/cart/products/Purple_of_Romagna_Artichoke-646-72.html has a malformed meta-tag like <meta content="text/html; charset=uft-8" http-equiv="Content-Type">) [Note "uft" instead of utf] my code is puking at the time I am trying to load the html document. Can someone suggest me how can I overcome these malformed html pages and still extract relevant text out of a html document? Thanks, Kapil

• JPA thinks I'm deleting a detached object

  - by Steve

  So, I've got a DAO that I used to load and save my domain objects using JPA. I finally managed to get the transaction stuff working (with a bunch of help from the folks here...), now I've got another issue. In my test case, I call my DAO to load a domain object with a given id, check that it got loaded and then call the same DAO to delete the object I just loaded. When I do that I get the following: java.lang.IllegalArgumentException: Removing a detached instance mil.navy.ndms.conops.common.model.impl.jpa.Group#10 at org.hibernate.ejb.event.EJB3DeleteEventListener.performDetachedEntityDeletionCheck(EJB3DeleteEventListener.java:45) at org.hibernate.event.def.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:108) at org.hibernate.event.def.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:74) at org.hibernate.impl.SessionImpl.fireDelete(SessionImpl.java:794) at org.hibernate.impl.SessionImpl.delete(SessionImpl.java:772) at org.hibernate.ejb.AbstractEntityManagerImpl.remove(AbstractEntityManagerImpl.java:253) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:48) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:600) at org.springframework.orm.jpa.SharedEntityManagerCreator$SharedEntityManagerInvocationHandler.invoke(SharedEntityManagerCreator.java:180) at $Proxy27.remove(Unknown Source) at mil.navy.ndms.conops.common.dao.impl.jpa.GroupDao.delete(GroupDao.java:499) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:48) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:600) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:304) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:182) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:149) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:106) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:204) at $Proxy28.delete(Unknown Source) at mil.navy.ndms.conops.common.dao.impl.jpa.GroupDaoTest.testGroupDaoSave(GroupDaoTest.java:89) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:48) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:600) at junit.framework.TestCase.runTest(TestCase.java:164) at junit.framework.TestCase.runBare(TestCase.java:130) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:120) at junit.framework.TestSuite.runTest(TestSuite.java:230) at junit.framework.TestSuite.run(TestSuite.java:225) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:130) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) Now given that I'm using the same DAO instance, and I've not changed EntityManagers (unless Spring does so without letting me know), how can this be a detached object?

• Maven 2 checkstyle plugin version 2.5 - Problem with configLocation

  - by Nils Schmidt

  Hi there, I am using checkstyle plugin in maven 2. I now want to switch my config file, from the default one to a) an online file, or b) a local file. I tried the following two things, which both didnt work. Any suggestions? A) Local file, which is directly in my project folder next to the pom.xml <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-checkstyle-plugin</artifactId> <configuration> <configLocation>checkstyle.xml</configLocation> </configuration> </plugin> B) Remote file, that is stored on a server <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-checkstyle-plugin</artifactId> <configuration> <configLocation>http://stud.hs-heilbronn.de/~nischmid/development/checkstyle-config.xml</configLocation> </configuration> </plugin> Both cases result in an error like this: [INFO] An error has occurred in Checkstyle report generation. Embedded error: Failed during checkstyle execution Could not find resource 'file:checkstyle.xml'. Any help would be appreciated!

• UML class diagram vs ER database diagram

  - by salva84

  Hi, I'm a little confused, I'm developing a program, the program consist in two parts, the server and the clients, there are groups, places, messages... stored in the server, and the clients has to connect with it. I've design the use cases diagram, the activity diagrams, and I have design the class diagram too. The thing is that I want to implement the server in a mysql tables for storing the users, groups, places... users in groups... so I've designed a E-R diagram consisting in 6 tables, but the problem is that I think that my class diagram and my ER diagram looks too similar, I mean, I think I'm not doing things right because I have a class for each table practically, and when I have to extract all the users on my system, do I have to convert all the rows into objects at first and write in the database for each object modified? The easy choice for me would be to base my whole application only in the database, and making a class to extract and insert data in it, but I have to follow the UML specification and I'm a little confused what to do with the class diagram, because the books I have read say that I have to create a class for each "entity" of my program. Sorry for my bad English. Thank you.

• Extracting files from merge module

  - by Mystagogue

  All I want is a command-line tool that can extract files from a merge module (.msm) onto disk. I'm trying msidb.exe and orca.exe The documentation for orca states: Many merge module options can be specified from the command line... Extracting Files from a Merge Module Orca supports three different methods for extracting files contained in a merge module. Orca can extract the individual CAB file, extract the files into a module tree and extract the files into a source image once it has been merged into a target database... Extracting Files To extract the individual files from a merge module, use the ... -x ... option on the command line, where is the desired path to the new directory tree. The specified path is used as the root path for the extracted files. All files are extracted from the CAB file embedded in the module and placed in the specified path. The directory layout for the extracted files is based on the directory tree of the merge module. It mostly sounds like exactly what I need. But when I try it, orca simply opens up an editor (with info on the msm I specified) and then does nothing. I've tried a variety of command lines, usually starting with this: orca -x theDirectory theModule.msm I use "theDirectory" as whatever empty folder I want. Like I said - it didn't do anything. Then I tried msidb, where a couple of attempts I've made look like this: msidb -d theModule.msm -w {storage} msidb -d theModule.msm -x {stream} In both cases, I don't know what to insert for {storage} or {stream} to make it happy - I don't know what those represent. Can someone explain what I'm doing wrong with the command line options? Is there any other tool that can do this?
