• Calling a wsdl in php over https using Zend Soap Client

  When I'm trying to connect to a webservice I always get the next fault SoapFault exception: [s:Sender] An error occurred when verifying security for the message I have to use a security header like: <o:Security env:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <wsu:Timestamp env:mustUnderstand="1" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <wsu:Created>2010-06-10T08:22:59Z</wsu:Created> <wsu:Expires>2010-06-12T10:22:59Z</wsu:Expires> </wsu:Timestamp> <o:UsernameToken> <o:Username>myUsername</o:Username> <o:Password>myPassword</o:Password> </o:UsernameToken> </o:Security> My username and password are correct, I have allready tried to change the expiration date later but that doesn't solve it.

• python-xmpp and looping through list of recipients to receive and IM message

  - by David

  I can't figure out the problem and want some input as to whether my Python code is incorrect, or if this is an issue or design limitation of Python XMPP library. I'm new to Python by the way. Here's snippets of code in question below. What I'd like to do is read in a text file of IM recipients, one recipient per line, in XMPP/Jabber ID format. This is read into a Python list variable. I then instantiate an XMPP client session and loop through the list of recipients and send a message to each recipient. Then sleep some time and repeat test. This is for load testing the IM client of recipients as well as IM server. There is code to alternately handle case of taking only one recipient from command line input instead of from file. What ends up happening is that Python does iterate/loop through the list but only last recipient in list receives message. Switch order of recipients to verify. Kind of looks like Python XMPP library is not sending it out right, or I'm missing a step with the library calls, because the debug print statements during runtime indicate the looping works correctly. recipient = "" delay = 60 useFile = False recList = [] ... elif (sys.argv[i] == '-t'): recipient = sys.argv[i+1] useFile = False elif (sys.argv[i] == '-tf'): fil = open(sys.argv[i+1], 'r') recList = fil.readlines() fil.close() useFile = True ... # disable debug msgs cnx = xmpp.Client(svr,debug=[]) cnx.connect(server=(svr,5223)) cnx.auth(user,pwd,'imbot') cnx.sendInitPresence() while (True): if useFile: for listUser in recList: cnx.send(xmpp.Message(listUser,msg+str(msgCounter))) print "sending to "+listUser+" msg = "+msg+str(msgCounter) else: cnx.send(xmpp.Message(recipient,msg+str(msgCounter))) msgCounter += 1 time.sleep(delay)

• Hibernate fails with NullPointerException in EntityTuplizerFactory.constructTuplizer? Why?

  - by Subtwo

  I have a problem when I try to instantiate Hibernate and connect with a MySQL database (see error message below).

• What is the suggested approach to Syncing/Backing up/Restoring from SQL Server 2008 to SQL Server 20

  - by Eoin Campbell

  I only have SQL Server 2008 (Dev Edition) on my development machine I only have SQL Server 2005 available with my hosting company (and I don't have direct connection access to this database) I'm just wondering what the best approach is for: Getting the initlal DB Structure & Data into production. And keeping any structural changes/data changes in sync in future. As far as I can see... Replication - not an option cos I can't connect to the production DB. Restoring a backup - not an option because as far as I can see, you cannot export a DB from 2008 that is restorable in 2005 (even with the 2008 DB set in 2005 compatibility mode) and it wouldn't make sense to be restoring production over the top of my dev version anyway. Dump all the scripts from my 2008 Database, Revert my Dev to machine from 2008 - 2005, and recreate the database from the scripts, then just use backup & restore to get the initial DB into production, then run scripts through the web panel from that point onwards Dump all the scripts from my 2008 Database and generate the entire 2005 db from scripts in production. then run scripts through the web panel from that point onwards With the last 2 options, I'd probably need to script all the data inserts as well using some tool (which I presume exists on the web) Are there any other possibile solutions that I'm not considering.

• FlashBuilder 4 and Zend Framework error

  - by sig

  I am trying to use adobe flash builder 4 with a php service. I had it set up an older macbook running leopard, but just tried to set it up on my new laptop running snow leopard. I did all the same steps.. set the Flex Server to be PHP, set the web root and url. Then I go to Data-Connect To PHP and point it to a php file I have in my web root. It says it needs to install Zend, and claims it does so successfully, but then when I try to continue, I get an error. I don't understand.. this same setup works on my older laptop.

• Unable to create website error (NEW)

  - by salvationishere

  I copied my ClickOnce deployment to my C:/Inetpub/ folder on my webserver and I deleted my Virtual directory. I deleted the WpfApplication1 folder beneath wwwroot in Win Explorer. Then I turned on Web Sharing for this folder. Then I viewed my IIS Manager and this new Share name appeared under wwwroot. So now under Inetpub folder on my web server I have the following directory path: C:\Inetpub\WpfApplication1\ with contents: Application Files publish.htm setup.exe WpfApplication1.application Next, I remapped both the publishing and installation URL's for the project to http://myserver/WpfApplication1/ And I clicked Publish Now. But after I performed a Publish Now operation, I got the following error on my development server (D610-M): Error 1 Failed to connect to 'http://myserver/WpfApplication1/' with the following error: Unable to create the Web site 'http://myserver/WpfApplication1/'. The Web server does not appear to have any authentication methods enabled. It asked for user authentication, but did not send a WWW-Authenticate header. 1 1 WpfApplication1 On my webserver, when I click Browse from the IIS Manager on the WpfApplication1 directory, it shows me the Install page. But after I click the Browse button, it returns an error which says: The remote name could not be resolved: 'd610-m' (D610-M is the name of my development server). How do I fix this?

• Avoiding CheckStyle magic number errors in JDBC queries.

  - by Dan

  Hello, I am working on a group project for class and we are trying out CheckStyle. I am fairly comfortable with Java but have never touched JDBC or done any database work before this. I was wondering if there is an elegant way to avoid magic number errors in preparedStatement calls, consider: preparedStatement = connect.prepareStatement("INSERT INTO shows " + "(showid, showtitle, showinfo, genre, youtube)" + "values (default, ?, ?, ?, ?);"); preparedStatement.setString(1, title); preparedStatement.setString(2, info); preparedStatement.setString(3, genre); preparedStatement.setString(4, youtube); result = preparedStatement.executeUpdate(); The setString methods get flagged as magic numbers, so far I just added the numbers 3-10 or so to the ignore list for magic numbers but I was wondering if there was a better way to go about inserting those values into the statement. I also beg you for any other advice that comes to mind seeing that code, I'd like to avoid developing any nasty habits, e.g. should I be using Statement or is PreparedStatement fine? Will that let me refer to column names instead? Is that ideal? etc... Thanks!

• Ruby on Rails - Static page as start page

  - by meetraghu28

  Hello! I am developing an app in RoR which has static and dynamic parts. The static portion is placed in the public/ folder of the app. Now if i have an index.html in my public folder then i will not be able to use the routes configured in my routes.rb The default configurations like map.connect /:controller/:action will not be usable if i have an index.html. So i removed the index html. Now i have a static page startpage.html in my public/ folder which has to be the starting page of the app. And the i have links in it for other static/dynamic pages. The RoR app is hosted in apache and i tried to configure the Virtual Host configuration by adding the DirectoryIndex param so that when ever a request comes for the site it will direct it to the startpage.html but still it takes me to the default controller that i have specified in routes.rb with map.root I dont want to add a dummy controller and action and create a view which has the startpage and configure routes.rb to use it as the root. What i am looking to do here is Basically startpage.html should be my first page in the app served as a static page from the public/ folder. This will then have links to other pages and controllers/actions Here i am not able to apache to redirect to the html page instead of passing on the control to rails application. Directory listing is also enabled by using Options Indexes but still no change. Any pointers anyone?

• Strange error when filling a data adapter.

  - by Tim C

  I am receiving the following error in my code (c#, .Net 3.5, VS2008) when I try to connect to an Excel sheet and fill a OleDbDataAdapter with the results of a query. First the error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. And here is the code, which is honestly pretty simple: var excelFileName = string.Format("c:/Metadata_Tool.xlsm"); var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0}; Extended Properties=Excel 12.0;HDR=YES;", excelFileName); var adapter = new OleDbDataAdapter("Select * FROM [Video Tagging XML]", connectionString); var ds = new DataSet(); adapter.Fill(ds, "VTX"); DataTable data = ds.Tables["VTX"]; foreach (DataRow myRow in data.Rows) { foreach (DataColumn myColumn in data.Columns) { Console.Write("\t{0}", myRow[myColumn]); } Console.WriteLine(); } Console.ReadLine(); I get the error on the line adapter.Fill(ds,"VTX");. I did find a microsoft forum post saying to turn on JIT optimization in VS2008 from the Tools/Options/Debug/General menu, but this did not seem to help. Any help would be greatly appreciated thanks!

• Unable to display wap version during "Extended permission"

  Hi, Im trying to redirect to facebook to request permission to publish stream. However, it only works when i did not specify any display parameters, it shows me a web version of it. I wanted a wap version instead. What should I do? Here's the code: <form method="post" action="https://graph.facebook.com/oauth/authorize"> <input type="hidden" name="client_id" value="1XXXXXXXXXXXXXX" /> <input type="hidden" name="scope" value="publish_stream" /> <input type="hidden" name="redirect_uri" value="http://www.redirect.com/" /> <input class="button" type="submit" value="Request..." /> </form> When i submit this form, it will redirect to http://www.facebook.com/connect/prompt_ … y=page.... If I were to change the "redirected url"'s display param to "wap" it will works. However, if I were to submit to https://graph.facebook.com/oauth/authorize?display=wap. Nothing will happen and it will redirect back to the source url. Any help/hint will be grateful. Thanks a mil, Mickey

• asyncsocket Write Issue

  - by James

  I am attempting to use asyncsocket to communicate GPS data from a server app on my iPhone to a client app on my macbook. The two devices connect without any problems, and when the first data is sent from the iPhone to the laptop in asyncsocket's didConnectToHost method, the data is sent without hiccup. When I subsequently try to write additional data to the laptop from the locationManager method, however, no data is written. Here is the code: - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { lat = [NSNumber numberWithFloat:newLocation.coordinate.latitude]; [lat retain]; NSLog(@"lat: %1.0f", [lat floatValue]); NSString *msg = [NSString stringWithFormat:@"%1.0f", [lat floatValue]]; NSData *msgData = [msg dataUsingEncoding:NSUTF8StringEncoding]; [listenSocket writeData:msgData withTimeout:-1 tag:0]; } listensocket is my instance of ASyncSocket. I know that no data is being sent because after the initial successful transfer, the didWriteDataWithTag method is not called. Can anyone explain this? Thanks! James

• CFHost DNS Resolution - When is it OK to use synchronous API?

  - by Jasarien

  I went to the iPhone Developer Tech Talk a few months ago and asked one of the gurus there about the lack of NSHost on the iPhone. Some code I was porting to the iPhone made significant use of NSHost throughout its networking code. I was told that NSHost is on the iPhone, but its private. I was also told that NSHost is a synchronous API and that I shouldn't use it anyway. (If anyone could elaborate on why it shouldn't be used, as a bonus, that'd be great.) I can see the caveats of using synchronous API's on the main thread in that they'll block until complete - and that's never a good thing with network code because there are so many factors that could cause the API to block the thread for a significant amount of time. My solution was to write a wrapper around CFHost's asynchronous resolution functions. The result works quite well, and I'm considering releasing it into the public domain. But my question is this: Say my app only resolves a hostname once per run, during the connecting phase, and then cache's it for the rest of the session. During the time it is resolving, a modal screen is shown telling the user "Connecting" with a nice spinner. Does it really matter whether or not the resolution is asynchronous?? The user has to wait to connect anyway, and the resolution is only done on the first connection. Subsequent connections use the cached result of the resolution. When is it OK to be synchronous and when should things be asynchronous?

• Porting an IBXpress Interbase 6 app to the current Firebird platform, on Delphi 7?

  - by robsoft

  Just wondering if there are any gotchas to be wary of here. We have a legacy D7 app that we developed several years ago for a client, which uses IBXpress to talk to the open source Interbase 6 build. We're having a number of issues with that platform these days (very slow to connect/start-up on new hardware being the chief one) and the client has okayed spending some time/money moving the database over to Firebird. We really DON'T want to embark upon moving it to D2010 (or D2007 which would be my preference right now) as we figure that we might have to move the database layer from IBXpress to something else to best suit Firebird anyway. And at the end of the day, the client is only looking to lessen the database pain, not overhaul/upgrade/rewrite the app. Given the ancestry of Firebird, is it a fairly painless, well-understood path from IBXpress Interbase 6 to (whatever) with Firebird? We have quite a number of sprocs, triggers (and even datatypes) etc in the existing IB database already (and the client has a number of paying customers all using this platform) so we felt that going to Firebird was more likely to be a smoother move than moving to SQL Express (or another flavour of DB entirely). Note that we're not looking for 'embedded' DB advocacy - in many of our client's customers' installations, the software is used in a multi-user client-server way so keeping that kind of approach is important.

• How to set ExportMetaData with multiple values as well as single w/ custom attribute ?

  - by Matthew M.

  I have the following ExportMetaData attributes set on my class: [Export(typeof(IDocumentViewer))] [ExportMetadata("Name", "MyViewer")] [ExportMetadata("SupportsEditing", true)] [ExportMetadata("Formats", DocFormat.DOC, IsMultiple = true)] [ExportMetadata("Formats", DocFormat.DOCX, IsMultiple = true)] [ExportMetadata("Formats", DocFormat.RTF, IsMultiple = true)] I also have a supporting interface: public interface IDocumentViewerMetaData { /// <summary> /// Gets the format. /// </summary> /// <value>The format.</value> IEnumerable<DocFormat> Formats { get; } /// <summary> /// Gets the name of the viewer /// </summary> /// <value>The name.</value> string Name { get; } /// <summary> /// Gets a value indicating whether this viewer supports editing /// </summary> /// <value><c>true</c> if [supports editing]; otherwise, <c>false</c>.</value> bool SupportsEditing { get; } } And of course my ImportMany: [ImportMany(typeof(IDocumentViewer))] public IEnumerable<Lazy<IDocumentViewer, IDocumentViewerMetaData>> _viewers { get; set; } What I would like to do is use a strongly-typed attribute class instead of using the ExportMetaData attribute. I have not figured out a way to do this while also supporting single values (Name, SupportsEditing, in the example above). I envision doing something similiar the following (or whatever is suggested as best): [Export(typeof(IDocumentViewer))] [DocumentViewerMetadata(Name = "MyViewer")] [DocumentViewerMetadata(SupportsEditing = true)] [DocumentViewerMetadata(Format = DocFormat.DOC)] [DocumentViewerMetadata(Format = DocFormat.DOCX)] I am fairly certain that there IS a way to do this, I just haven't found the right way to connect the dots. :) Thank you, Matthew

• how to implement login and service features as in skype or msn chat in a wpf application

  - by black sensei

  Hello Good people! I'm building an WPF application that connect to web services for its operations.Things that i needed to be working are so far fine.Now i'll like to improve use experience by adding features like username editable combobox, sign me in when skype start and start when computer start. I have a fair idea about each feature but very small knowledge about their implementation. Question 1 username combobox : i use a combobox with isEditable set to true but i think it doesnt have the previous username, would that mean that i have to store every successful login username in a sqlite for example? Question 2 sign me in when skype start : i think about using sqlite after all to store the credentials and store the value (as in true or false) if autologin has to be performed. Question 3 start when computer start : i know it's about having is as service.but the process of using it as a service and removing its service when checkbox is checked or unckecked is a bit confusing to me. Question 4 Please wait(signing in) of skype if i want to do things like please wait at login(login is over webservice) in a WPF application should i use a animated gif in a grid that i can show when hiding the login combobox and passwordbox grid or i should use an animated object(for which i have no knowledge about for now) ? This post in mainly for you experts to either point me to the right resource and tell me what is done as best practice. things like dos and dons.Thanks for reading this and please let me have a clair idea about how to start implementing those features. thanks again

For example, I'm trying to use the cx_Oracle library, which is perfectly working if called from the python interpeter of from simple scripts made with some text editor. But I cant make it work inside Eclipse: I have this small piece of code: import cx_Oracle conn = cx_Oracle.connect(CONN_STRING) sql = "select field from mytable" cursor = conn.cursor() cursor.execute(sql) for row in cursor: field = row[0] print field If I execute it from Eclipse, I get the following error: import cx_Oracle File "build/bdist.macosx-10.6-universal/egg/cx_Oracle.py", line 7, in <module> File "build/bdist.macosx-10.6-universal/egg/cx_Oracle.py", line 6, in __bootstrap__ ImportError: dlopen(/Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so, 2): Library not loaded: /b/227/rdbms/lib/libclntsh.dylib.10.1 Referenced from: /Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so Reason: no suitable image found. Did find: /Users/dave/lib/libclntsh.dylib.10.1: mach-o, but wrong architecture Same snippet works perfectly from the python shell I have configured the interpeter in Eclipse in preferences - PyDev -- Interpreter - Python, using the Auto Config option and selecting all the libs found. What am I doing wrong here? Edit: launching file /Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so from the command line tells this: /Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so: Mach-O universal binary with 3 architectures /Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so (for architecture i386): Mach-O bundle i386 /Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so (for architecture ppc7400): Mach-O bundle ppc /Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so (for architecture x86_64): Mach-O 64-bit bundle x86_64

• Object created in Interface Builder getting dealloc'ed too soon

  - by Collin Allen

  The Project I'm working on a relatively simple iPhone OS project that's navigation controller based, with a root table view and a detail table view. Tap an item in the main list to see its details in a pushed table view. The Setup I broke out the data source for both views into their own objects so as not to muddy the purpose of a view controller. Having done this, the table views no longer have data sources since those methods are now in separate files, so I created an instance of each data source class in the appropriate XIB files with the Object item (dragged it in, then set its class). Then, to actually connect the tableviews to their data sources, I set the dataSource outlet of each tableview to the yellow data source object in Interface Builder. The table view delegates are still set to their view controllers. The Problem The root table view works just fine, but when you tap a row to push to the detail view, the data source object gets instantiated as expected, then immediately dealloc'ed, causing a crash (numberOfSectionsInTableView: gets called on the freed object). I can't figure out why the data source is getting automatically dealloc-ed when I need it right then and there for the detail view, as indicated by my data source object creation and tableview connection in Interface Builder. What's more perplexing is that the very approach works fine for the root tableview! The Question Is there anything obvious I'm missing that would cause this to happen? Or, is this even the right way to instantiate a data source for a table view controller? It seems like poor object oriented programming to do it from within the view controller, which should only be concerned with the view. I could cram everything in two table view controller classes and it would probably work, but it would not be as modular as I'd like. Thanks!

• process of connecting RTP with SIP via SDP & land lines

  - by TacB0sS

  Hello to everyone, I have a problem with starting a media session and to combine it with my SIP client. I've designed a recursive SIP client that reuse the same request template to send the next requests to server, according to the acceptable sequences noted in the RFC's, and examples that I read. as far as I could tell the SIP part is working fine registers to server invites, and authenticates. I didn't complete any calls to clients yet because of the content header needs to be filled up (which I didn't yet so I get a 503 from the server which is OK I guess). for a long time I didn't know where to start with the media session, and slowly learned how to use the JMF and I've constructed an object that handles RTP transmitting, now I'm standing at the cross road, on the one hand I have my SIP signaling but it needs the SDP content header to complete the invite, and on the other I have the RTP which is knows how to p2p. For me to complete my design I require your help with the following questions: Is there an easy//a simple//an implemented way to convert the Audio/Video format from the JMF into SDP media headers? or even a generator that I would input all the parameters for the content header, and it would generate a content header fast, or do I have to implement this myself? Once I've finished constructing the SDK and the SIP is up and running and I get an OK response from the server (after ringing and all), how do I start the media session? do I connect p2p according to caller details I send in the SIP invite? If 2 is correct, then how does a connection to land lines would be? does land lines knows that once they send an OK back to server they listen/start RTP session on a specific port? Or did I get everything wrong? :-/ I really appreciate any help I could I get, I looked every where for answers but they are not clear, they ignore question 2 as if it was an obvious thing, but for me it just isn't. Thank in advance, Adam Zehavi.

• Can't get SFTP to work in PHP

  - by Chris Kloberdanz

  I am writing a simple SFTP client in PHP because we have the need to programatically retrieve files via n remote servers. I am using the PECL SSH2 extension. I have run up against a road block, though. The documentation on php.net suggests that you can do this: $stream = fopen("ssh2.sftp://$sftp/path/to/file", 'r'); However, I have an ls method that attempts to something similar public function ls($dir) { $rd = "ssh2.sftp://{$this->sftp}/$dir"; $handle = opendir($rd); if (!is_resource($handle)) { throw new SFTPException("Could not open directory."); } while (false !== ($file = readdir($handle))) { if (substr($file, 0, 1) != '.'){ print $file . "\n"; } } closedir($handle); } I get the following error: PHP Warning: opendir(): Unable to open ssh2.sftp://Resource id #5/outgoing on remote host This makes perfect sense because that's what happens when you cast a resource to string. Is the documentation wrong? I tried replacing the resource with host, username, and host and that didn't work either. I know the path is correct because I can run SFTP from the command line and it works fine. Has anyone else tried to use the SSH2 extenstion with SFTP? Am I missing something obvious here? UPDATE: I setup sftp on another machine in-house and it works just fine. So, there must be something about the server I am trying to connect to that isn't working.

• SqlBackup from my client app

  - by Robbert Dam

  I have an client app that runs on several machines, and connects to a single SQL database. On the client app, the user has the possiblity to use a local SQL (CE) database or connect to a remote SQL database. There is also a box where a backup location can be set. For the backup of the remote SQL database I use the following code: var bdi = new BackupDeviceItem(backupFile, DeviceType.File); var backup = new Backup { Database = "AppDb", Initialize = true }; backup.Devices.Add(bdi); var server = new Server(connection); backup.SqlBackup(server); When developing my application, I wasn't aware that the given backupFile is written on the machine where the SQL server runs! And not on the client machine. What I want is "dump" all the data from my database to a local file. (Why? Because users may enter a network location in the "backup location" box, and backing up SQL immediately to a network location fails. So need to write local first and then copy to the network in that case.) I there an alternative to the method above?
