Log4j Dynamic Parameter

- by cedric

Hi. i have a j2ee web application running on spring framework and using log4j for logging. I have this line in my log4j.properties file. this will insert the logs in my database. How do I set a dynamic value in the message part so that I can somehow append the currently logged in user. The bean object containing info for the current user is in the application context. log4j.appender.dbLog.sql = INSERT INTO LOGGING (log_date, log_level, location, message) VALUES ('%d{yyyy/MM/dd HH:mm:ss}', '%-5p', '%C-%L', '%m')

Call Init from XUL after Page Loads (Firefox add-on)

- by mattyboy123

Hi all, I've been working on some code in js/html and it works great. I'm now trying to package it into an add-on for Firefox, and having some issues getting the XUL document correct. PLAIN OLD HTML/JS In my html test file between the <head></head> I have: <script type="text/javascript" src="js/MyCode.js"></script> At the end of the test file before the </body> I have: <script type="text/javascript">MyCode.Static.Init();</script> FIREFOX ADD-ON: OVERLAY.XUL In an overlay.xul file in the extension package I have : <?xml version="1.0"?> <overlay id="mycode" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script type="application/x-javascript" src="chrome://mycode/content/MyCode.js"></script> <script> window.addEventListener("load", function () { gBrowser.addEventListener("load",MyCode.Static.Init,true); }, false); </script> </overlay> This does not seem to enter the method, but then again I'm not even sure if I've got the listeners firing properly. Would this be the correct way to duplicate what I was doing in plain old html/js ?

Which Dependency Injection Tool Should I Use? (2)

- by Mendy

The original post is: Which Dependency Injection Tool Should I Use? While the original post is good, in this days I see a lot of people using StructureMap as their Dependency Injection tool, and in the original post no one even took it seriously. In addition, this quote: If I had to choose today: I would probably go with StructureMap. It has the best support for C# 3.0 language features, and the most flexibility in initialization. Which Dependency Injection Tool Should I Use? Out of this ones: Unity Framework - Microsoft StructureMap - Jeremy Miller Castle Windsor NInject Spring Framework Autofac Managed Extensibility Framework

Why wouldn't a flex remoteobject be able to work within a custom component?

- by Gary

Please enlighten this flex noob. I have a remoteobject within my main.mxml. I can call a function on the service from an init() function on my main.mxml, and my java debugger triggers a breakpoint. When I move the remoteobject declaration and function call into a custom component (that is declared within main.mxml), the remote function on java-side no longer gets called, no breakpoints triggered, no errors, silence. How could this be? No spelling errors, or anything like that. What can I do to figure it out? mxml code: < mx:RemoteObject id="myService" destination="remoteService" endpoint="$(Application.application.home}/messagebroker/amf" > < /mx:RemoteObject > function call is just 'myService.getlist();' when I move it to a custom component, I import mx.core.Application; so the compiler doesn't yell my child component: child.mxml <mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()" > <mx:Script> <![CDATA[ import mx.core.Application; public function init():void { helloWorld.sayHello(); } ]]> </mx:Script> <mx:RemoteObject id="helloWorld" destination="helloService" endpoint="$(Application.application.home}/messagebroker/amf" /> <mx:Label text="{helloWorld.sayHello.lastResult}" /> </mx:Panel> my main.mxml: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()" xmlns:test="main.flex.*" > <mx:Script> <![CDATA[ [Bindable] public var home:String; [Bindable] public var uName:String; public function init():void { //passed in by wrapper html home = Application.application.parameters.appHome; uName = Application.application.parameters.uName; } ]]> </mx:Script> <test:child /> </mx:Application>

What are the real-world benefits of declarative-UI languages such as XAML and QML?

- by Stu Mackellar

I'm currently evaluating QtQuick (Qt User Interface Creation Kit) which will be released as part of Qt 4.7. QML is the JavaScript-based declarative language behind QtQuick. It seems to be a very powerful concept, but I'm wondering if anybody that's made extensive use of other, more mature declarative-UI languages like XAML in WPF or Silverlight can give any insight into the real-world benefits that can be gained from this style of programming. Various advantages are often cited: Speed of development Forces separation between presentation and logic Better integration between coders and designers UI changes don't require re-compilation Also, are there any downsides? A few potential areas of concern spring to mind: Execution speed Memory usage Added complexity Are there any other considerations that should be taken into account?

ASP.NET-MVC Page: image logo is not displaying while sending the email

- by Rita

Hi I have a page that sends an email on ASP.NET MVC Page. All the Text is displaying but the image is not displaying. Any workaround. Appreciate your responses. Here is my code: MailMessage mailMsg = new MailMessage(); mailMsg.IsBodyHtml = true; mailMsg.From = new MailAddress(ConfigurationManager.AppSettings["Email.Sender"]); mailMsg.To.Add(new MailAddress(email)); mailMsg.Subject = "Test mail to display the Logo in the email"; mailMsg.Body = " Test mail to display the Logo in the email; mailMsg.Body += Environment.NewLine + Environment.NewLine + "<html><body><img src=cid:companylogo/><br></body></html>"; //Insert Logo string logoPath = Server.MapPath(Links.Content.images.Amgen_MedInfo_Logo_jpg); // logo is placed in images folder LinkedResource logo = new LinkedResource(logoPath); logo.ContentId = "companylogo"; // done HTML formatting in the next line to display logo AlternateView aView = AlternateView.CreateAlternateViewFromString(mailMsg.Body, new System.Net.Mime.ContentType("text/html")); aView.LinkedResources.Add(logo); mailMsg.AlternateViews.Add(aView); mailMsg.IsBodyHtml = true; SmtpClient smtpClient = new SmtpClient(ConfigurationManager.AppSettings["SMTP"]); smtpClient.Send(mailMsg);

WPF TextBlock Binding to DependencyProperty

- by Bill Campbell

Hi, I have what I believe to be about one of the most simple cases of attempting to bind a view to a dependencyproperty in the view model. It seems that the initial changes are reflected in the view but other changes to the DP do not update the view's TextBlock. I'm probably just missing something simple but I just can't see what it is. Please take a look... My XAML has a status bar on the bottom of the window. I want to bind to the DP "VRAStatus". <StatusBar x:Name="sbar" Grid.Column="0" Grid.Row="2" Grid.ColumnSpan="2" VerticalAlignment="Bottom" Background="LightBlue" Opacity="0.4" DockPanel.Dock="Bottom" > <StatusBarItem> <TextBlock x:Name="statusBar" Text="{Binding VRAStatus}" /> </StatusBarItem> <StatusBarItem> <Separator Style="{StaticResource StatusBarSeparatorStyle}"/> </StatusBarItem> </StatusBar> My viewmodel has the DP defined: public string VRAStatus { get { return (string)GetValue(VRAStatusProperty); } set { SetValue(VRAStatusProperty, value); } } // Using a DependencyProperty as the backing store for VRAStatus. public static readonly DependencyProperty VRAStatusProperty = DependencyProperty.Register("VRAStatus", typeof(string), typeof(PenskeRouteAssistViewModel),new PropertyMetadata(string.Empty)); Then, in my code I set the DP: VRAStatus = "Test Message..."; Is there something obvious here that I am missing? In my constructor for the viewmodel I set the DP like this: VRAStatus = "Ready"; I never get the Test Message to display. Please Help. thanks in advance! Bill

How to use Java varargs with the GWT Javascript Native Interface? (aka, "GWT has no printf()")

- by markerikson

I'm trying to quickly learn GWT as part of a new project. I found out that GWT doesn't implement Java's String.format() function, so there's no printf()-like functionality. I knew that some printf() implementations exist for Javascript, so I figured I could paste one of those in as a GWT Javascript Native Interface function. I ran into problems, and decided I'd better make sure that the varargs values were being passed in correctly. That's where things got ugly. First, some example code: // From Java, call the JSNI function: test("sourceString", "params1", "params2", "params3"); .... public static native void test(Object... params) /*-{ // PROBLEM: this kills GWT! // alert(params.length); // returns "function" alert(typeof(params)); // returns "[Ljava.lang.Object;@b97ff1" alert(params); }-*/; The GWT docs state that "calling a varargs JavaScript method from Java will result in the callee receiving the arguments in an array". I figured that meant I could at least check params.length, but accessing that throws a JavascriptException wrapped in an UmbrellaException, with no real information. When I do "typeof(params)", it returns "function". As if that weren't odd enough, if I check the string value of params, it returns what appears to be a string version of a Java reference. So, I guess I'm asking a few different questions here: 1) How do GWT/JSNI varargs actually work, and do I need to do something special to pass in values? 2) What is actually going on here? 3) Is there any easier way to get printf()-style formatting in a GWT application?

WCF Callback Faulted - what happens to the session?

- by RemotecUk

Just trying to get my head around what can happen when things go wrong with WCF. I have an implementation of my service contract declared with an InstanceContextMode of PerSession... [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Multiple)] The calls happen as follows: My client calls the server and calls GetServerUTC() to return the current UTC time of the server. This is a one way call and the server will call the client back when its ready (trivial in this instance to simply return the current time!) The server calls back to the client and for test purposes in the callback implementation on the client I throw an exception. This goes unhandled in the client (for test purposes) and the client crashes and closes down. On the server I handle the faulted event handler on the ICommunicationObject... obj.Faulted += new EventHandler(EventService_Faulted); Questions... Will this kill off the session for the current connection on the server. I presume I am free to do what I want in this method e.g. logging or something, but should I do anything specific here to terminate the session or will WCF handle this? From a best practise view point what should I do when the callback is faulted? Does it mean "something has happened in your client" and thats the end of that or is there something I a missing here? Additionally, are there any other faulted handlers I should be handling. Ive done a lot of reading on WCF and it seems sort of vague on what to do when something goes wrong. At present I am implementing a State Machine on my client which will manage the connection and determine if a user action can happen dependant on if a connection exists to the server - or is this overkill. Any tips would be really appreciated ;)

Linq to SQL Problem System.Data.Linq.IdentityManager.StandardIdentityManager.MultiKeyManager

- by luckyluke

I have a really tricky thing going up here. My project has around 100 tables and they are all mapped by LINQ. Everything works fine in a dev and test environment. These enviroments are MS Win 2008 r2 servers with SQL 2008 sp1 databases. IIS and SQL are on a different machines. Now on production enviroment which is MS Win 2003 x64 web farm + geoclustered SQL 2008 IT DOES not work. All I get is the exception System.IndexOutOfRangeException: Index was outside the bounds of the array. at System.Data.Linq.IdentityManager.StandardIdentityManager.MultiKeyManager3.TryCreateKeyFr>om Values(Object[] values, MultiKey& k) at System.Data.Linq.IdentityManager.StandardIdentityManager.IdentityCache2.Find(Object[] keyValues) at System.Data.Linq.ChangeProcessor.GetOtherItem(MetaAssociation assoc, Object instance) at System.Data.Linq.ChangeProcessor.BuildEdgeMaps() at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at ERS.IIMP.Services.ExposuresSrv.Update(Int32 ExpID, Int32 AssID) Services\ExposuresSrv.cs` My question is What the hell. They have precisely the same DBML, the DB has exactly THE SAME structure (when I get the DB from prod to TEST and mount it eveything works just great), the binaries on the WEB Server are the same. I seriously do not know what to do.... Did anyone found that Linq works on one env and does not on the second?? I mam really lost here. I really hope You can help me:)

What makes a bad programming language bad?

- by sub

We have all seen things like the typing system of JavaScript (There is a funny post including a truth table somewhere around here). I consider this one of the main things that makes a programming language bad. Other things that spring to mind: Bad Error messages (Either obfuscated so you can't figure out whats wrong, not existing or simply too long and red) The language wasn't planned and just grew uncontrolled in all directions (PHP?) The language encourages bad programm(er/ing) habits such as: Global variables everywhere, bad variable names Inconsistent naming conventions inside the language I can't come up with any more at the moment and would be very happy to read what you think about this. What shouldn't be missing in a language created to be as bad (from the perspectives of the programmer, the company that hires to programmer, the team leader and the customer) as possible? (I ask this because I'm designing a bad, experimental language at the moment)

Header Setup in SOAP with ASP.NET 3.5 WCF

- by Adam

I'm pretty new to SOAP so go easy on me. I'm trying to setup a SOAP service that accepts the following header format: <soap:Header> <wsse:Security> <wsse:UsernameToken wsu:Id='SecurityToken-securityToken'> <wsse:Username>Username</wsse:Username> <wsse:Password>Password</wsse:Password> <wsu:Created>Timestamp</wsu:Created> </wsse:UsernameToken> </wsse:Security> </soap:Header> The application I'm incorporating this service into is an ASP.NET 3.5 web application and I've already setup a SOAP endpoint using WCF. I've setup a basic service to make sure the WCF works and it works fine (disregarding the header). I heard that the above format follows WS-Security so I added WSHttpBinding in the web.config: <service name="Nexternal.Service.XMLTools.VNService" behaviorConfiguration="VNServiceBehavior">  <endpoint address="" binding="wsHttpBinding" contract="Nexternal.Service.XMLTools.IVNService"/> </service> I downloaded a test harness (soapUI) and pasted in a test message with the above header and it came back with a 400 Bad Request error. ...for what it's worth, I'm running Visual Studio 2008 using IIS7. I feel like I'm going in circles so any help would be awesome. Thanks in advance.

Use of Hibernate 3.0 with EJB 3.0 & JPA

- by SOA Nerd

Where I'm working the guys that are sitting across from me are working on a project. This is a JavaEE app which uses Struts, Spring, EJB 3.0, JPA, and Hibernate 3.0. They are using EJB 3.0 entity beans with annotations. I've been asking them why Hibernate 3.0 is in this mix and noone can seem to tell me. It feels like they've included Hibernate 3.0 because they were told to but are not using it for anything that they can't get from EJB 3.0 entity beans/JPA. They're using CMP and accessing all of the database functions via EJBs. Can Hibernate give you anything in this setup that can't be provided by EJB 3.0/JPA?

Retrieve Flash file post in ASP.NET

- by Quandary

Question: In ASP.NET, I retrieve a JPEG-file as Flash post data like this Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest context.Response.ContentType = "text/plain" ' Retrieve a bytearray from the post buffer Dim myBuffer As Byte() = context.Request.BinaryRead(Convert.ToInt32(context.Request.InputStream.Length)) System.IO.File.WriteAllBytes("c:\temp\test.jpg", myBuffer) End Sub In Flash, I send it to an asp.net handler like this var jpgSource:BitmapData = cPrint.TakeSnapshot(MovieClip(cGlobals.ccPlanZoomView)); var bmpThisBitmap:Bitmap = new Bitmap(jpgSource); var nQuality:Number = 100; var jpgEncoder:JPGEncoder = new JPGEncoder(nQuality); var jpgStream:ByteArray = jpgEncoder.encode(jpgSource); var header:URLRequestHeader = new URLRequestHeader ("Content-type", "application/octet-stream"); // Make sure to use the correct path to jpg_encoder_download.php var strFileName:String="test.jpg"; var jpgURLRequest:URLRequest = new URLRequest("http://localhost/raumplaner_new/raumplaner_new/cgi-bin/SavePDF.ashx"); //var scriptVars:URLVariables = new URLVariables(); //scriptVars.fn = strFileName; //var myarr:Array= new Array(); //myarr.push(jpgStream); //scriptVars.Files = myarr; jpgURLRequest.requestHeaders.push(header); jpgURLRequest.method = URLRequestMethod.POST; //jpgURLRequest.data = scriptVars; jpgURLRequest.data = jpgStream; var loader:URLLoader = new URLLoader(); loader.dataFormat = URLLoaderDataFormat.BINARY; loader.load(jpgURLRequest); It works but I want to send a few additional variables along, via scriptVars (commented out here). How do I retrieve the JPEG file in that case ? Because if I use parameters, there is no more BinaryRead... Aspecially, how would I read an array of jpeg files (several files) ?

AS3: Array of objects parsed from XML remains with zero length

- by Joel Alejandro

I'm trying to parse an XML file and create an object array from its data. The data is converted to MediaAlbum classes (class of my own). The XML is parsed correctly and the object is loaded, but when I instantiate it, the Albums array is of zero length, even when the data is loaded correctly. I don't really know what the problem could be... any hints? import Nem.Media.*; var mg:MediaGallery = new MediaGallery("test.xml"); trace(mg.Albums.length); MediaGallery class: package Nem.Media { import flash.net.URLRequest; import flash.net.URLLoader; import flash.events.*; public class MediaGallery { private var jsonGalleryData:Object; public var Albums:Array = new Array(); public function MediaGallery(xmlSource:String) { var loader:URLLoader = new URLLoader(); loader.load(new URLRequest(xmlSource)); loader.addEventListener(Event.COMPLETE, loadGalleries); } public function loadGalleries(e:Event):void { var xmlData:XML = new XML(e.target.data); var album; for each (album in xmlData.albums) { Albums.push(new MediaAlbum(album.attribute("name"), album.photos)); } } } } XML test source: <gallery <albums <album name="Fútbol 9" <photos <photo width="600" height="400" filename="foto1.jpg" / <photo width="600" height="400" filename="foto2.jpg" / <photo width="600" height="400" filename="foto3.jpg" / </photos </album <album name="Fútbol 8" <photos <photo width="600" height="400" filename="foto4.jpg" / <photo width="600" height="400" filename="foto5.jpg" / <photo width="600" height="400" filename="foto6.jpg" / </photos </album </albums </gallery

In Seam what's the difference between injected EntityManager and getEntityManager from EntityHome

- by Navi

I am testing a Seam application using the needle test API. In my code I am using the getEntityManager() method from EntityHome. When I run the unit tests against an in memory database I get the following exception: java.lang.IllegalStateException: No application context active at org.jboss.seam.Component.forName(Component.java:1945) at org.jboss.seam.Component.getInstance(Component.java:2005) at org.jboss.seam.Component.getInstance(Component.java:1983) at org.jboss.seam.Component.getInstance(Component.java:1977) at org.jboss.seam.Component.getInstance(Component.java:1972) at org.jboss.seam.framework.Controller.getComponentInstance(Controller.java:272) at org.jboss.seam.framework.PersistenceController.getPersistenceContext(PersistenceController.java:20) at org.jboss.seam.framework.EntityHome.getEntityManager(EntityHome.java:177) etc .. I can resolve some of these errors by injecting the EntityManager with @In EntityManager entityManager; Unfortunately the persist method of EntityHome also calls the getEntityManager. This means a lot of mocks or rewriting the code somehow. Is there any workaround and why is this exception thrown anyway? I am using Seam 2.2.0 GA by the way. There is nothing special about the components. They are generated by seam-gen. The test is performed with in memory database - I followed the examples in http://jbosscc-needle.sourceforge.net/jbosscc-needle/1.0/db-util.html.

Will running aspnet_regiis.exe -ir create any problems?

- by alexander-strandberg

Hi there. I've asked a question about changing the version of .Net sites in the IIS. If it affects classic asp sites etc (See Does asp.net setting affect classic asp (IIS 6 settings)) And that seems fine. So my follow-up question is, will running this command get me fired? What it does is changing the default value (and all existing?) of the .net version to 2.0. This wont affect any of the .net sites since they're allready versioned to 2.0. The classic asp pages needs to get its app pools updated so its functionoal with 2.0 but may I run into any other troubles? I've tried doing this on a test environment and no sites whet down during the installation period (from the command) but I did not have any classic asp sites or any .net sites running though (which I should test, come to think about it) but may something else break? Is this command doing anything else? We have some very large sites running and we cannot have downtime periods so I need to be 100% sure that this command is safe. Since all sites go down everytime we change a new sites .net version number we need to get this fix live asap. Any good ideas?

log4j vs. System.out.println - logger advantages?

- by wishi_

Hi! I'm newly using log4j in a project. A fellow programmer told me that using System.out.println is considered bas style and that log4j is something like standard for logging matters nowadays. We do lots of JUnit testing - System.out stuff turns out to be harder to test. Therefore I began utilizing log4j for a Console controller class, that's just handling commandline parameters. // some logger config org.apache.log4j.BasicConfigurator.configure(); Logger logger = LoggerFactory.getLogger(Console.class); Category cat = Category.getRoot(); Seems to work: logger.debug("String"); Produces: 1 [main] DEBUG project.prototype.controller.Console - String I got two questions regarding this: From my basic understanding using this logger should provide me comfortable options to write a logfile with timestamps - instead of spamming the console - if debug mode is enabled at the logger? Why is System.out.println harder to test? I searched stackoverflow and found a testing recipe. So I wonder what kind of advantage I really get by using log4j.

Word 2007 COM - Can't directly access a page when word is set to invisible

- by Robbie

I'm using Word 2007 via COM from PHP 5.2 Apache 2.0 on a windows machine. The goal is to programmatically render jpeg thumbnails from each page in a Word document. The following code works correctly if you set $word-Visible to 1: try { $word = new COM('word.application'); $word->Visible = 0; $word->Documents->Open("C:\\test.doc"); echo "Number of pages: " . $word->ActiveDocument->ActiveWindow->ActivePane->Pages->Count() . "</br>"; $i = 1; foreach ($word->ActiveDocument->ActiveWindow->ActivePane->Pages as $page) { echo "Page number: $i </br>"; $i++; } //get the EMF image of the page $data = $word->ActiveDocument->ActiveWindow->ActivePane->Pages->Item(3)->EnhMetaFileBits; $word->ActiveDocument->Close(); $word->Quit(); } catch (Exception $e) { echo "Exception: " .$e->getMessage(); } The test document I'm using contains 35 pages. The code will display the correct number of pages but the for each loop only loops over 1 page. I can only directly access page 1 and 2 in the Pages-Item() collection. If I try to access another page I get the exception: "The requested member of the collection does not exist." If I set the $word-Visible property to 1 I do get all the pages in the foreach loop and I can access any page directly. Everything is working as expected if Word is set to be visible. Even stranger is the fact that if I set Word to be invisible and I don't have the foreach loop I can only access page 1 instead of page 1 and 2 if I do the for each loop. Any pointers on how I can access all the pages in the document and keeping word invisible?

Django's self.client.login(...) does not work in unit tests

- by thebossman

I have created users for my unit tests in two ways: 1) Create a fixture for "auth.user" that looks roughly like this: { "pk": 1, "model": "auth.user", "fields": { "username": "homer", "is_active": 1, "password": "sha1$72cd3$4935449e2cd7efb8b3723fb9958fe3bb100a30f2", ... } } I've left out the seemingly unimportant parts. 2) Use 'create_user' in the setUp function (although I'd rather keep everything in my fixtures class): def setUp(self): User.objects.create_user('homer', '[email protected]', 'simpson') Note that the password is simpson in both cases. I've verified that this info is correctly being loaded into the test database time and time again. I can grab the User object using User.objects.get. I can verify the password is correct using 'check_password.' The user is active. Yet, invariably, self.client.login(username='homer', password='simpson') FAILS. I'm baffled as to why. I think I've read every single Internet discussion pertaining to this. Can anybody help? The login code in my unit test looks like this: login = self.client.login(username='homer', password='simpson') self.assertTrue(login) Thanks.

CURL & web.py: transfer closed with outstanding read data remaining

- by Richard J

Hi Folks, I have written a web.py POST handler, thus: import web urls = ('/my', 'Test') class Test: def POST(self): return "Here is your content" app = web.application(urls, globals()) if __name__ == "__main__": app.run() When I interact with it using Curl from the command line I get different responses depending on whether I post it any data or not: curl -i -X POST http://localhost:8080/my HTTP/1.1 200 OK Transfer-Encoding: chunked Date: Thu, 06 Jan 2011 16:42:41 GMT Server: CherryPy/3.1.2 WSGI Server Here is your content (Posting of no data to the server gives me back the "Here is your content" string) curl -i -X POST --data-binary "@example.zip" http://localhost:8080/my HTTP/1.1 100 Content-Length: 0 Content-Type: text/plain HTTP/1.1 200 OK Transfer-Encoding: chunked Date: Thu, 06 Jan 2011 16:43:47 GMT Server: CherryPy/3.1.2 WSGI Server curl: (18) transfer closed with outstanding read data remaining (Posting example.zip to the server results in this error) I've scoured the web.py documentation (what there is of it), and can't find any hints as to what might be going on here. Possibly something to do with 100 continue? I tried writing a python client which might help clarify: h1 = httplib.HTTPConnection('localhost:8080') h1.request("POST", "http://localhost:8080/my", body, headers) print h1.getresponse() body = the contents of the example.zip, and headers = empty dictionary. This request eventually timed out without printing anything, which I think exonerates curl from being the issue, so I believe something is going on in web.py which isn't quite right (or at least not sufficiently clear) Any web.py experts got some tips? Cheers, Richard

RDP through TCP Proxy

- by johng100

Hi, First time in Stackoverflow and I'm hoping someone can help me. I'm looking at a proof of concept to pass RDP traffic through a TCP Proxy/tunnel which will pass through firewalls using HTTPS. The problem has to do with deploying images to machines and so it can't be assumed that the .NET framework will be present, so C++ is being used at the deployment end of a connection. The basic system I have at present is a program which listens for client connections on a port then passes any data to a WCF service which stores it as a byte array. A deployment machine (using GSoap and C++) polls the WCF service for messages and if it finds them then passes the data onto the target server process via sockets. I know this sounds horrible, but it works for simple test clients and server passing data to and from simple test client and server programs via this WCF/C++/C# proxy layer. But I have to support traffic from RDP, VNC and possibly others, so I need a transparent proxy to do this and am wondering whether the above approach is worth pursuing. I've read up on SSH tunneling and that seems a possibility. My basic question is is it possible to tunnel RDP traffic over HTTPS using custom code. Thanks John

It is all right in Solvers.xaml because there really is no DockingManager but MainWindow.xaml should work, shouldn't it? How to solve the problem? Note: It seems to me that the files are processed separately and because the file Solvers.xaml contains the error the MainWindow.xaml file also contains the very same error. Note 2: XAML files use AvalonDock library Is there a way how to say that Solvers.xaml is only an extension of another file? Thank you for any help!

How to limit traffic using multicast over localhost

- by Shane Holloway

I'm using multicast UDP over localhost to implement a loose collection of cooperative programs running on a single machine. The following code works well on Mac OSX, Windows and linux. The flaw is that the code will receive UDP packets outside of the localhost network as well. For example, sendSock.sendto(pkt, ('192.168.0.25', 1600)) is received by my test machine when sent from another box on my network. import platform, time, socket, select addr = ("239.255.2.9", 1600) sendSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP) sendSock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, 24) sendSock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_IF, socket.inet_aton("127.0.0.1")) recvSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP) recvSock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, True) if hasattr(socket, 'SO_REUSEPORT'): recvSock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, True) recvSock.bind(("0.0.0.0", addr[1])) status = recvSock.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, socket.inet_aton(addr[0]) + socket.inet_aton("127.0.0.1")); while 1: pkt = "Hello host: {1} time: {0}".format(time.ctime(), platform.node()) print "SEND to: {0} data: {1}".format(addr, pkt) r = sendSock.sendto(pkt, addr) while select.select([recvSock], [], [], 0)[0]: data, fromAddr = recvSock.recvfrom(1024) print "RECV from: {0} data: {1}".format(fromAddr, data) time.sleep(2) I've attempted to recvSock.bind(("127.0.0.1", addr[1])), but that prevents the socket from receiving any multicast traffic. Is there a proper way to configure recvSock to only accept multicast packets from the 127/24 network, or do I need to test the address of each received packet?

change custom mapping - sharp architecture/ fluent nhibernate

- by csetzkorn

I am using the sharp architecture which also deploys FNH. The db schema sql code is generated during the testing like this: [TestFixture] [Category("DB Tests")] public class MappingIntegrationTests { [SetUp] public virtual void SetUp() { string[] mappingAssemblies = RepositoryTestsHelper.GetMappingAssemblies(); configuration = NHibernateSession.Init( new SimpleSessionStorage(), mappingAssemblies, new AutoPersistenceModelGenerator().Generate(), "../../../../app/XXX.Web/NHibernate.config"); } [TearDown] public virtual void TearDown() { NHibernateSession.CloseAllSessions(); NHibernateSession.Reset(); } [Test] public void CanConfirmDatabaseMatchesMappings() { var allClassMetadata = NHibernateSession.GetDefaultSessionFactory().GetAllClassMetadata(); foreach (var entry in allClassMetadata) { NHibernateSession.Current.CreateCriteria(entry.Value.GetMappedClass(EntityMode.Poco)) .SetMaxResults(0).List(); } } /// <summary> /// Generates and outputs the database schema SQL to the console /// </summary> [Test] public void CanGenerateDatabaseSchema() { System.IO.TextWriter writeFile = new StreamWriter(@"d:/XXXSqlCreate.sql"); var session = NHibernateSession.GetDefaultSessionFactory().OpenSession(); new SchemaExport(configuration).Execute(true, false, false, session.Connection, writeFile); } private Configuration configuration; } I am trying to use: using FluentNHibernate.Automapping; using xxx.Core; using SharpArch.Data.NHibernate.FluentNHibernate; using FluentNHibernate.Automapping.Alterations; namespace xxx.Data.NHibernateMaps { public class x : IAutoMappingOverride<x> { public void Override(AutoMapping<Tx> mapping) { mapping.Map(x => x.text, "text").CustomSqlType("varchar(max)"); mapping.Map(x => x.url, "url").CustomSqlType("varchar(max)"); } } } To change the standard mapping of strings from NVARCHAR(255) to varchar(max). This is not picked up during the sql schema generation. I also tried: mapping.Map(x = x.text, "text").Length(100000); Any ideas? Thanks. Christian
