• WCF Service Exception

  - by Maciek

  Hiya, I'm currently working on an Silverlight 3 project, I'm using 2 machines to test it. "harbinger" is the web server running Win7 + IIS . I've deployed the webpage and the WCF webservice to that machine. I've entered the following url's in my browser : http://harbinger:43011/UserService.svc http://harbinger:43011/UserService.svc?wsdl and got pages load expected contents for both Next I've decided to check if I can call the webservice from my machine, I've added the ServiceReference, executed a call to one of the methods and .... BOOM : System.ServiceModel.CommunicationException was unhandled by user code Message="An error occurred while trying to make a request to URI 'http://harbinger:43011/UserService.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent.

• CKEditor instance already exists

  - by jackboberg

  I am using jquery dialogs to present forms (fetched via AJAX). On some forms I am using a CKEditor for the textareas. The editor displays fine on the first load. When the user cancels the dialog, I am removing the contents so that they are loaded fresh on a later request. The issue is, once the dialog is reloaded, the CKEditor claims the editor already exists. uncaught exception: [CKEDITOR.editor] The instance "textarea_name" already exists. The API includes a method for destroying existing editors, and I have seen people claiming this is a solution: if (CKEDITOR.instances['textarea_name']) { CKEDITOR.instances['textarea_name'].destroy(); } CKEDITOR.replace('textarea_name'); This is not working for me, as I receive a new error instead: TypeError: Result of expression 'i.contentWindow' [null] is not an object. This error seems to occur on the "destroy()" rather than the "replace()". Has anyone experienced this and found a different solution? Is is possible to 're-render' the existing editor, rather than destroying and replacing it? UPDATED Here is another question dealing with the same problem, but he has provided a downloadable test case.

• How to scrape a _private_ google group?

  - by John

  Hi there, I'd like to scrape the discussion list of a private google group. It's a multi-page list and I might have to this later again so scripting sounds like the way to go. Since this is a private group, I need to login in my google account first. Unfortunately I can't manage to login using wget or ruby Net::HTTP. Surprisingly google groups is not accessible with the Client Login interface, so all the code samples are useless. My ruby script is embedded at the end of the post. The response to the authentication query is a 200-OK but no cookies in the response headers and the body contains the message "Your browser's cookie functionality is turned off. Please turn it on." I got the same output with wget. See the bash script at the end of this message. I don't know how to workaround this. am I missing something? Any idea? Thanks in advance. John Here is the ruby script: # a ruby script require 'net/https' http = Net::HTTP.new('www.google.com', 443) http.use_ssl = true path = '/accounts/ServiceLoginAuth' email='[email protected]' password='topsecret' # form inputs from the login page data = "Email=#{email}&Passwd=#{password}&dsh=7379491738180116079&GALX=irvvmW0Z-zI" headers = { 'Content-Type' => 'application/x-www-form-urlencoded', 'user-agent' => "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/533.2 (KHTML, like Gecko) Chrome/6.0"} # Post the request and print out the response to retrieve our authentication token resp, data = http.post(path, data, headers) puts resp resp.each {|h, v| puts h+'='+v} #warning: peer certificate won't be verified in this SSL session Here is the bash script: # A bash script for wget CMD="" CMD="$CMD --keep-session-cookies --save-cookies cookies.tmp" CMD="$CMD --no-check-certificate" CMD="$CMD --post-data='[email protected]&Passwd=topsecret&dsh=-8408553335275857936&GALX=irvvmW0Z-zI'" CMD="$CMD --user-agent='Mozilla'" CMD="$CMD https://www.google.com/accounts/ServiceLoginAuth" echo $CMD wget $CMD wget --load-cookies="cookies.tmp" http://groups.google.com/group/mygroup/topics?tsc=2

• ASP.NET MVC Session Expiration

  - by Andrew Flanagan

  We have an internal ASP.NET MVC application that requires a logon. Log on works great and does what's expected. We have a session expiration of 15 minutes. After sitting on a single page for that period of time, the user has lost the session. If they attempt to refresh the current page or browse to another, they will get a log on page. We keep their request stored so once they've logged in they can continue on to the page that they've requested. This works great. However, my issue is that on some pages there are AJAX calls. For example, they may fill out part of a form, wander off and let their session expire. When they come back, the screen is still displayed. If they simply fill in a box (which will make an AJAX call) the AJAX call will return the Logon page (inside of whatever div the AJAX should have simply returned the actual results). This looks horrible. I think that the solution is to make the page itself expire (so that when a session is terminated, they automatically are returned to the logon screen without any action by them). However, I'm wondering if there are opinions/ideas on how best to implement this specifically in regards to best practices in ASP.NET MVC.

• MySQL performance - 100Mb ethernet vs 1Gb ethernet

  - by Rob Penridge

  Hi All I've just started a new job and noticed that the analysts computers are connected to the network at 100Mbps. The ODBC queries we run against the MySQL server can easily return 500MB+ and it seems at times when the servers are under high load the DBAs kill low priority jobs as they are taking too long to run. My question is this... How much of this server time is spent executing the request, and how much time is spent returning the data to the client? Could the query speeds be improved by upgrading the network connections to 1Gbps? (Updated for the why): The database in question was built to accomodate reporting needs and contains massive amounts of data. We usually work with subsets of this data at a granular level in external applications such as SAS or Excel, hence the reason for the large amounts of data being transmitted. The queries are not poorly structured - they are very simple and the appropriate joins/indexes etc are being used. I've removed 'query' from the Title of the post as I realised this question is more to do with general MySQL performance rather than query related performance. I was kind of hoping that someone with a Gigabit connection may be able to actually quantify some results for me here by running a query that returns a decent amount of data, then they could limit their connection speed to 100Mb and rerun the same query. Hopefully this could be done in an environment where loads are reasonably stable so as not to skew the results. If ethernet speed can improve the situation I wanted some quantifiable results to help argue my case for upgrading the network connections. Thanks Rob

• Amazon Web services - retrieving a wishlist

  - by izb

  I've been tinkering with Yahoo Pipes and the Amazon E-Commerce Service (ECS) SDK to retrieve my wishlist. The problem is that although I can get all the items on my wishlist just fine, it seems to include items that I've deleted too. Has anyone else used this API and noticed this? Is there a way around it? UPDATE: Requested additional information in comments... Here is the URL I use to fetch the wishlist XML: http://webservices.amazon.co.uk/onca/xml?SubscriptionId=[my subs id]&Service=AWSECommerceService&ResponseGroup=ListItems&ProductPage=1&ProductGroup=Book&Operation=ListLookup&ListType=WishList&ListId=[my list id] And here is the relevant part of the XML response: <ListId>[my list id]</ListId> <ListName>Wishlist</ListName> <TotalItems>132</TotalItems> <TotalPages>14</TotalPages> <ListItem> <ListItemId>EPIE5559HKT391</ListItemId> <DateAdded>2003-11-17</DateAdded> <QuantityDesired>1</QuantityDesired> <QuantityReceived>0</QuantityReceived> <Item> <ASIN>5557205521</ASIN> <ItemAttributes> <Title>Horton hears a who</Title> </ItemAttributes> </Item> </ListItem> ... The rest of the XML is just either more list items like that, or information about the request at the top of the response.

• EF4 querying from parent to grandchildren

  - by Hans Kesting

  I have a model withs Parents, Children and Grandchildren, in a many-to-many relationship. Using this article I created POCO classes that work fine, except for one thing I can't yet figure out. When I query the Parents or Children directly using LINQ, the SQL reflects the LINQ query (a .Count() executes a COUNT in the database and so on) - fine. The Parent class has a Children property, to access it's children. But (and now for the problem) this doesn't expose an IQueryable interface but an ICollection. So when I access the Children property on a particular parent all the Parent's Children are read. Even worse, when I access the Grandchildren (theParent.Children.SelectMany(child => child.GrandChildren).Count()) then for each and every child a separate request is issued to select all data of it's grandchildren. That's a lot of separate queries! Changing the type of the Children property from ICollection to IQueryable doesn't solve this. Apart from missing methods I need, like Add() and Remove(), EF just doesn't recognize the navigation property then. Are there correct ways (as in: low database interaction) of querying through children (and what are they)? Or is this just not possible?

• Using db4o with multiple application instances under medium trust

  - by Anders Fjeldstad

  I recently stumbled over the object database engine db4o which I think looks really interesting. I would like to use it in an ASP.NET MVC application that will be deployed to a shared hosting environment under medium trust. Because of the trust level, I'm restricted to using db4o in embedded/in-process mode. That in itself should be no problem, but the hosting provider also transparently runs each web application in multiple (load-balanced) server instances with shared storage, which I would say is normally a very nice feature for a $10/month hoster. However, since an instance of a db4o server with write access (whether in-process or networked) locks the underlying database file, having multiple instances of the application using the same file won't work (or at least I can't see how it would). So the question is: is it possible to use db4o in this specific environment? I have considered letting each application have its own database which is synchronized with a master database using replication (dRS), but that approach will most likely end up with very frequent bi-directional replication (read master changes at beginning of each request, write to master after each change) which I don't think will be very efficient. Summary of the web application/environment characteristics: Read-intensive (but not entirely read-only) Some delay (a few seconds) is acceptible between the time that a change is made and the time when the change shows up in all the application instances' data Must run in medium trust No guarantee that the load-balancer uses "sticky sessions" All suggestions are much appreciated!

• 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.

• Why would Basic Auth not work with my WCF client to Java SOAP Web Service?

  - by orj

  I have a Java based web service that requires basic authentication to communicate with it. If I type the WSDL url into my browser I'm prompted for Basic Auth. Which I can get by entering the correct credentials. However using my WCF client doesn't work. I construct my WCF client like this: var binding = new BasicHttpBinding { MaxReceivedMessageSize = 2048 * 10240, Security = { Mode = BasicHttpSecurityMode.TransportCredentialOnly, Transport = { ClientCredentialType = HttpClientCredentialType.Basic, Realm = "MYREALM", ProxyCredentialType = HttpProxyCredentialType.None }, Message = { ClientCredentialType = BasicHttpMessageCredentialType.UserName, AlgorithmSuite = SecurityAlgorithmSuite.Default } } }; var client = new WebServiceClient(binding, endpoint); client.ClientCredentials.UserName.UserName = username; client.ClientCredentials.UserName.Password = password; client.DoWebServiceMethod(); I get the following exception. System.Net.WebException: The remote server returned an error: (401) Unauthorized. at System.Net.HttpWebRequest.GetResponse() at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout) System.ServiceModel.Security.MessageSecurityException: The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was 'Basic realm="MYREALM"'. From what I can tell I'm doing things right. Where am I going wrong?

• WCF - Increase ReaderQuoatas on REST service

  - by Christo Fur

  I have a WCF REST Service which accepts a JSON string One of the parameters is a large string of numbers This causes the following error - which is visible by tracing and using SVC Trace Viewer There was an error deserializing the object of type CarConfiguration. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Now I've read all sorts of articles advising how to rectify this All of them recommend increasing various config settings on the server and client e.g. http://stackoverflow.com/questions/65452/error-serializing-string-in-webservice-call http://bloggingabout.net/blogs/ramon/archive/2008/08/20/wcf-and-large-messages.aspx http://social.msdn.microsoft.com/Forums/en/wcf/thread/f570823a-8581-45ba-8b0b-ab0c7d7fcae1 So my config file looks like this <webHttpBinding> <binding name="webBinding" maxBufferSize="5242880" maxReceivedMessageSize="5242880" > <readerQuotas maxDepth="5242880" maxStringContentLength="5242880" maxArrayLength="5242880" maxBytesPerRead="5242880" maxNameTableCharCount="5242880"/> </binding> </webHttpBinding> ... ... ... <endpoint address="/" binding="webHttpBinding" bindingConfiguration="webBinding" My problem is that I can change this on the server, but there are no WCF config settings on the client as its a REST service and I'm just making a http request using the WebClient object any ideas?

My main code is as simple as possible: before do ensure_application_is_installed_by_facebook_user @user = session[:facebook_session].user @photos = session[:facebook_session].get_photos(nil,@user.uid,nil) end get "/" do erb :index end get "/:uid/:image" do |uid,image| @photo_selected = session[:facebook_session].get_photos([image.to_i],nil,nil) erb :selected end The index page just renders a link to the other one (identified by regex "/:uid/:image") however I always get an error when it's trying to render the one identified by regex "/:uid/:image" Facebooker::Session::MissingOrInvalidParameter: Invalid parameter /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/parser.rb:610:in `process' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/parser.rb:30:in `parse' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/service.rb:67:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:600:in `post_without_logging' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:611:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/logging.rb:20:in `log_fb_api' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/benchmark.rb:308:in `realtime' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/logging.rb:20:in `log_fb_api' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:610:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:198:in `secure!' ./config/frankie/lib/frankie.rb:66:in `secure_with_token!' ./config/frankie/lib/frankie.rb:44:in `set_facebook_session' ./config/frankie/lib/frankie.rb:164:in `ensure_authenticated_to_facebook' ./config/frankie/lib/frankie.rb:169:in `ensure_application_is_installed_by_facebook_user' I've no idea why, it seems to be related with the auth token I guess.. I logged the request made o the fb rest server: {:sig="4f244d1f510498f4efaae3c03d036a85", :generate_session_secret="0", :method="facebook.auth.getSession", :auth_token="9dae0d02c19c680b574c78d202b0582a", :api_key="70c14732815ace0ae71a561ea5eb38b7", :v="1.0"} {:call_id="1269003766.05665", :sig="194469457d1424dc8ba0678979692363", :method="facebook.photos.get", :subj_id=750401957, :session_key="2.lXL0z3s4_r573xzQwAiA9A__.3600.1269010800-750401957", :api_key="70c14732815ace0ae71a561ea5eb38b7", :v="1.0"} {:sig="4f244d1f510498f4efaae3c03d036a85", :generate_session_secret="0", :method="facebook.auth.getSession", :auth_token="9dae0d02c19c680b574c78d202b0582a", :api_key="70c14732815ace0ae71a561ea5eb38b7", :v="1.0"} The last one gives the error, it could be related with auth_token having the same value in the 1st and on the 3rd ? Cheers and tks, Ze Maria

• How to Global onRouteRequest directly to onBadRequest?

  - by virtualeyes

  EDIT Came up with this to sanitize URI date params prior to passing off to Play router val ymdMatcher = "\\d{8}".r // matcher for yyyyMMdd URI param val ymdFormat = org.joda.time.format.DateTimeFormat.forPattern("yyyyMMdd") def ymd2Date(ymd: String) = ymdFormat.parseDateTime(ymd) override def onRouteRequest(r: RequestHeader): Option[Handler] = { import play.api.i18n.Messages ymdMatcher.findFirstIn(r.uri) map{ ymd=> try { ymd2Date( ymd); super.onRouteRequest(r) } catch { case e:Exception => // kick to "bad" action handler on invalid date Some(controllers.Application.bad(Messages("bad.date.format"))) } } getOrElse(super.onRouteRequest(r)) } ORIGINAL Let's say I want to return a BadRequest result type for all /foo URIs: override def onBadRequest(r: RequestHeader, error: String) = { BadRequest("Bad Request: " + error) } override def onRouteRequest(r: RequestHeader): Option[Handler] = { if(r.uri.startsWith("/foo") onBadRequest("go away") else super.onRouteRequest(r) } Of course does not work, since the expected return type is Option[play.api.mvc.Handler] What's the idiomatic way to deal with this, create a default Application controller method to handle filtered bad requests? Ideally, since I know in onRouteRequest that /foo is in fact a BadRequest, I'd like to call onBadRequest directly. Should note that this is a contrived example, am actually verifying a URI yyyyMMdd date param, and BadRequest-ing if it does not parse to a JodaTime instance -- basically a catch-all filter to sanitize a given date param rather than handling on every single controller method call, not to mention, avoiding cluttering up application log with useless stack traces re: invalid date parse conversions (have several MBs of these junk trace entries accruing daily due to users pointlessly manipulating the uri date in attempts to get at paid subscriber content)

• .NET SAP Connection Authentication via WEB Service

  - by mehmet6parmak

  Hi, I am trying to connect to a web service served by SAP and i have authentication problem. I simply added the service by right clicking project, selecting add service reference, giving WSDL url for the service and clicking OK.(After clicking ok asked for credentials and i provided them) Then when i tried to call a method from the serviceclien object i got the error message below: The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Basic realm="SAP Web Application Server <hostname>"'. Web Config Related Part: <basicHttpBinding> <binding name="binding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm=""> <extendedProtectionPolicy policyEnforcement="Never" /> </transport> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> Also, What problems will i face with?

• How to parse a raw HTTP response?

  - by Ed

  If I have a raw HTTP response as a string: HTTP/1.1 200 OK Date: Tue, 11 May 2010 07:28:30 GMT Expires: -1 Cache-Control: private, max-age=0 Content-Type: text/html; charset=UTF-8 Server: gws X-XSS-Protection: 1; mode=block Connection: close <!doctype html><html>...</html> Is there an easy way I can parse it into an HttpListenerResponse object? Or at least some kind .NET object so I don't have to work with raw responses. What I'm doing currently is extracting the header key/value pairs and setting them on the HttpListenerResponse. But some headers can't be set, and then I have to cut out the body of the response and write it to the OutputStream. But the body could be gzipped, or it could be an image, which I can't get to work yet. And some responses contain random characters everywhere, which looks like an encoding problem. It's a lot of trouble. I'm getting a raw response because I'm using SOCKS to send an HTTP request. The program I'm working on is basically an HTTP proxy that can route requests through a SOCKS proxy, like Privoxy does.

• UpdatePanel doesn't load correctly on second try

  - by Ed Woodcock

  Ok, I've got two UpdatePanels on a (relatively simple) CRUD-management page, and I'm having some issues with them. The first updatepanel fails the second time it's updated (infinite loading popout, page doesn't change, request comes back properly but apparently isn't used). The second updatepanel fails if the first updatepanel has updated first, or if a certain internal trigger is pressed twice. Interestingly, the first updatepanel can be called multiple times with no problems if the first has yet to be called. layout example: <updatepanel> <table> <trigger> </table> </updatepanel> <lightbox> <updatepanel> <multiple triggers> </updatepanel> </lightbox> The use of the second updatepanel is required for the lightbox to function correctly (so it can't just be one big one). The first updatepanel exhibits this behaviour regardless of whether the second is present on the page or not. Has anyone ever experienced similar problems/have any ideas?

• JavaScript variable to ColdFusion variable

  - by Alexander

  I have a tricky one. By means of a <cfoutput query="…"> I list some records in the page from a SQL Server database. By the end of each line viewing I try to add this in to a record in a MySQL database. As you see is simple, because I can use the exact variables from the output query in to my new INSERT INTO statement. BUT: the rsPick.name comes from a database with a different character set and the only way to get it right into my new database is to read it from the web page and not from the value came in the output query. So I read this value with that little JavaScript I made and put it in the myValue variable and then I want ColdFusion to read that variable in order to place it in my SQL statement. <cfoutput query="rsPick"> <tr> <td>#rsPick.ABBREVIATION#</td> <td id="square"> #rsPick.name# </td> <td>#rsPick.Composition#</td> <td> Transaction done... <script type="text/javascript"> var myvalue = document.getElementById("square").innerHTML </script> </td> <cfquery datasource="#Request.Order#"> INSERT INTO products (iniid, abbreviation, clsid, cllid, dfsid, dflid, szsid, szlid, gross, retail, netvaluebc, composition, name) VALUES ( #rsPick.ID#, '#rsPick.ABBREVIATION#', #rsPick.CLSID#, #rsPick.CLLID#, #rsPick.DFSID#, #rsPick.DFLID#, #rsPick.SZSID#, #rsPick.SZLID#, #rsPick.GROSSPRICE#, #rsPick.RETAILPRICE#, #rsPick.NETVALUEBC#, '#rsPick.COMPOSITION#','#MYVALUE#' ) </cfquery> </tr> </cfoutput>
