• Can i use a different parser for Axis 1.4?

  - by NishM

  The current SAX parser takes a lot of time (20 minutes) and heap memory(around 400mb) to deserialize the response coming from the soap server as per the logs. Our response XMLs are of average size 4 mb. A part of the log when it runs the applicaiton out of heap is below DEBUG (org.apache.axis.encoding.DeserializationContext) Pushing handler org.apache.axis.message.SOAPHandler@16d22f1 DEBUG (org.apache.axis.i18n.ProjectResourceBundle) org.apache.axis.i18n.resource::handleGetObject(newElem00) DEBUG (org.apache.axis.message.MessageElement) New MessageElement (org.apache.axis.message.MessageElement@112c22) named {}name DEBUG (org.apache.axis.encoding.DeserializationContext) Pushing element name DEBUG (org.apache.axis.utils.NSStack) NSPush (32) DEBUG (org.apache.axis.encoding.DeserializationContext) Exit: DeserializationContext::startElement() DEBUG (org.apache.axis.encoding.DeserializationContext) Enter: DeserializationContext::endElement(, name) DEBUG (org.apache.axis.i18n.ProjectResourceBundle) org.apache.axis.i18n.resource::handleGetObject(popHandler00) DEBUG (org.apache.axis.encoding.DeserializationContext) Popping handler org.apache.axis.message.SOAPHandler@16d22f1 DEBUG (org.apache.axis.utils.NSStack) NSPop (32) DEBUG (org.apache.axis.encoding.DeserializationContext) Popped element stack to org.apache.axis.message.MessageElement:property DEBUG (org.apache.axis.encoding.DeserializationContext) Exit: DeserializationContext::endElement() DEBUG (org.apache.axis.encoding.DeserializationContext) Enter: DeserializationContext::startElement(, value) DEBUG (org.apache.axis.i18n.ProjectResourceBundle) org.apache.axis.i18n.resource::handleGetObject(pushHandler00) DEBUG (org.apache.axis.encoding.DeserializationContext) Pushing handler org.apache.axis.message.SOAPHandler@16880ba DEBUG (org.apache.axis.i18n.ProjectResourceBundle) org.apache.axis.i18n.resource::handleGetObject(newElem00) DEBUG (org.apache.axis.message.MessageElement) New MessageElement (org.apache.axis.message.MessageElement@1db74af) named {}value DEBUG (org.apache.axis.encoding.DeserializationContext) Pushing element value DEBUG (org.apache.axis.utils.NSStack) NSPush (32) DEBUG (org.apache.axis.encoding.DeserializationContext) Exit: DeserializationContext::startElement() DEBUG (org.apache.axis.encoding.DeserializationContext) Enter: DeserializationContext::endElement(, value) DEBUG (org.apache.axis.i18n.ProjectResourceBundle) org.apache.axis.i18n.resource::handleGetObject(popHandler00) DEBUG (org.apache.axis.encoding.DeserializationContext) Popping handler org.apache.axis.message.SOAPHandler@16880ba DEBUG (org.apache.axis.utils.NSStack) NSPop (32) I cannot use Axis2 because of technical reasons. I have tried using HTTP Commons client instead of HTTP client but the response time remains the same. How can i link a different parser(example xerces 2.10.0 or xstream 1.3.1?) to Axis 1.4 framework in this context so that memory management and response time is favorable?.

• Model validation with enumerations

  - by Robert Koritnik

  I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

• Sorting tasks to assign

  - by Diego

  I've got a problem that I don't know where to start. I'd realy appreciate some help. The problem: I have several T task that must be done in D days by just 1 employee (let's forget using several resources right now). Each task can be done in some times (not all tasks can be done all time). e.g.: If my employee starts working at 8 o'clock and one task is "call a client". Maybe the client office opens at 9 o'clock. Also each task has a duration (really estimated). It is supposed that the D days are enough to do all task. I've to sort the tasks to the employee. e.g.: at monday 8:00 do task 7, then at 9:30 starts with task 2. In the example task 7 duration would be 1 and a half hour. Thanks for the help! Diego PD: If someone has a way to make this and it is not an algorithm never minds, please answer and I'll manage to think the algorithm. I just don't know how to face the problem. Edit Would Project be usefull? Edit 2 Tasks / Jobs dependency is NOT required

• how to group by over anonymous type with vb.net linq to object

  - by smoothdeveloper

  I'm trying to write a linq to object query in vb.net, here is the c# version of what I'm trying to achieve (I'm running this in linqpad): void Main() { var items = GetArray( new {a="a",b="a",c=1} , new {a="a",b="a",c=2} , new {a="a",b="b",c=1} ); ( from i in items group i by new {i.a, i.b} into g let p = new{ k = g, v = g.Sum((i)=>i.c)} where p.v > 1 select p ).Dump(); } // because vb.net doesn't support anonymous type array initializer, it will ease the translation T[] GetArray<T>(params T[] values){ return values; } I'm having hard time with either the group by syntax which is not the same (vb require 'identifier = expression' at some places, as well as with the summing functor with 'expression required' ) Thanks so much for your help!

• WSE 3.0 crashes when ClearHeaders is called

  - by Daniel Enetoft

  Hi! I'm developing a client-server application in c# using WSE web-service. One of the things that the user can do is send jpg images to the server for backup via the web-service. Recently strange errors have occurred. This does not happen for all users, just a few. On the client side the exception is a System.Net.WebException Exception message: The operation has timed out and on the server the following warning is found in the event viewer: Exception information: Exception type: HttpException Exception message: Server cannot clear headers after HTTP headers have been sent. Request information Request URL: MyUrl/Service.asmx Request path: /MyWebService/Service.asmx User host address: ------- User: Is authenticated: False Authentication Type: Thread account name: NT AUTHORITY\NETWORK SERVICE Thread information: Thread ID: 7 Thread account name: NT AUTHORITY\NETWORK SERVICE Is impersonating: False Stack trace: at System.Web.HttpResponse.ClearHeaders() at System.Web.Services.Protocols.SoapServerProtocol.WriteException(Exception e, Stream outputStream) at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing) at System.Web.Services.Protocols.WebServiceHandlerFactory.CoreGetHandler(Type type, HttpContext context, HttpRequest request, HttpResponse response) Does anyone have an idea where this error can come from? I have already tried to raise the "maxRequestLength" in web.config to 16Mb but this doesn't fix it. Regards /Daniel

• Getting a new session key after Facebook offline_access permission

  - by Richard

  I have a mobile application that I'm using with Facebook connect. I'm having trouble getting an offline_access session key after a user has granted extended permissions. Here's the user flow: User goes to my site for the first time I send them to m.facebook.com/tos.php? and pass my api key and secret The user logs in using Facebook connect Facebook returns them to a page in my site, mysite/login-success.php with an auth_token in the query string On mysite/login-success.php I instantiate the FB api client and check to see if I already have an offline_access session key for them: $facebook = new Facebook($appapikey, $appsecret); If they haven't already provided offline_access FB gives me a temporary session key I need to get offline_access permission from the user so I forward them on to www.facebook.com/connect/prompt_permissions.php? and pass offline_access in the querystring. The user authorizes offline_access and get forwarded to mysite/permissions-success.php The problem I'm having is that after instantiating the API client on permissions-success.php the session key I have is still the temporary session key, not a new offline_access session key. The only way I've found to get the offline_access key is to delete all cookies for the user and then have them login again using Facebook connect. A fairly poor user experience. Can anyone shed some light on how to use the Facebook api to generate a new session key even if one already exists (in my case a temporary session key)?

• Nonblocking Tcp server

  - by hoodoos

  It's not a question really, i'm just looking for some guidelines :) I'm currently writing some abstract tcp server which should use as low number of threads as it can. Currently it works this way. I have a thread doing listening and some worker threads. Listener thread is just sits and wait for clients to connect I expect to have a single listener thread per server instance. Worker threads are doing all read/write/processing job on clients socket. So my problem is in building efficient worker process. And I came to some problem I can't really solve yet. Worker code is something like that(code is really simple just to show a place where i have my problem): List<Socket> readSockets = new List<Socket>(); List<Socket> writeSockets = new List<Socket>(); List<Socket> errorSockets = new List<Socket>(); while( true ){ Socket.Select( readSockets, writeSockets, errorSockets, 10 ); foreach( readSocket in readSockets ){ // do reading here } foreach( writeSocket in writeSockets ){ // do writing here } // POINT2 and here's the problem i will describe below } it works all smothly accept for 100% CPU utilization because of while loop being cycling all over again, if I have my clients doing send-receive-disconnect routine it's not that painful, but if I try to keep alive doing send-receive-send-receive all over again it really eats up all CPU. So my first idea was to put a sleep there, I check if all sockets have their data send and then putting Thread.Sleep in POINT2 just for 10ms, but this 10ms later on produces a huge delay of that 10ms when I want to receive next command from client socket.. For example if I don't try to "keep alive" commands are being executed within 10-15ms and with keep alive it becomes worse by atleast 10ms :( Maybe it's just a poor architecture? What can be done so my processor won't get 100% utilization and my server to react on something appear in client socket as soon as possible? Maybe somebody can point a good example of nonblocking server and architecture it should maintain?

• OpenId ASP MVC Authentication with long expiry

  - by Khash

  Stackoverflow uses OpenId as many other websites. However, I rarely need to provide my OpenId to Stackoverflow while with other OpenId enabled websites, I have to do it once a day or week. This suggests to me that the expiry of the session is with the website and not the OpenId provider. Looking at the DotNetOpenId code in ASP MVC, I can see that after a successful authentication by the OpenId provider FormsAuthentication.SetAuthCookie is called with the identifier and a boolean parameter to determine if the cookie should be persisted. How can I force this cookie to expire, say in 2020 instead of whatever the default value is.

• Google App Engine application instance recycling and response times...

  - by Konrad

  Hi, I posted this on GAE for Java group, but I hope to get some answers here quicker :) I decided to do some long-run performance tests on my application. I created some small client hitting app every 5-30 minutes and I run 3-5 of threads with such client. I noticed huge differenced in response times and started to investigate issue. I found reason very quick. I am experiencing same issues as described in following topics: Uneven response time between connection to server to first byte sent Application instances seem to be too aggressively recycled Getting 'Request was aborted after waiting too long to attempt to service your request.' after application idle I am using Springframework, it tkes around 18-20s to start app instance, which is causing response times to take from 1s (when requests hits running app - very rare) to 22s when fresh application is created. Is there any solution for this? I was thinking about creating most basic servlet performing critical tasks (serving API call) and leave UI as is. But then I would loose all benefits of Springframework. Is there any solution for this? After solving (hacking) numerous constrains of App Engine which I hit while developing my app that is the one I think will make me move out of App Engine... that's simply to much to all the time think how to win with GAE problems than how to solve my application problems... Any help? Regards Konrad

• Web service SSL handshake fails in production environment unless SSL debugging enabled

  - by JST

  Scenario: calling a client web service over SSL (https) with mutual SSL authentication. Different service endpoint URLs and certs (both keystore and truststore) for test vs. production environments. Both test and production environments run tomcat / JBoss clustered. Production environment has load balancing / BigIP, runs Blade and non-Blade machines. Truststore is set (using -Djavax.net.ssl.trustStore=value) at startup. Keystore is set using System.setProperty("javax.net.ssl.keyStore", "value") in Java code. Web service call made using Axis2. All works fine in test environment, but when we moved to production environment (6 servers), it appears certs are not being forwarded for the handshake. Here's what we've done: in test environment, handshake using test versions of certs has been working all along, with no ssl debugging enabled confirmed in test environment that handshake with client production endpoint succeeds (production certs, both ours and theirs, are fine) -- this was done using -Djavax.net.debug=handshake,ssl confirmed that the error condition occurs on all 6 production servers took one server out of the cluster, turned on ssl debugging for just that one (with a restart), hit it directly, handshake works! switched to a different server without the debugging turned on, handshake error condition occurs turned debugging on on that second server (with a restart), hit it directly, handshake works! From the evidence, it seems like somehow the debugging being enabled causes the certificates to be properly retrieved/conveyed, although that makes no sense! I wonder whether somehow the enabled debugging makes the system pay attention to the System.setProperty call, and ignore it otherwise. However, in local and test environments, handshake worked without debugging enabled. Do I maybe need to be setting keystore on server startup like I'm setting truststore? Have been avoiding that because the keystore will differ for each of our test environments (16 of them).

• Mercurial Remote Subrepos

  - by Travis G

  I'm trying to set up my Mercurial repository system to work with multiple subrepos. I've basically followed these instructions to set up the client repo with Mercurial client v1.5 and I'm using HgWebDir to host my multiple projects. I have an HgWebDir with the following structure: http://myserver/hg fooproj mylib where mylib is some collection of common template library to be consumed by fooproj. The structure of fooproj looks like this: fooproj doc/ src/ .hgignore .hgsub .hgsubstate And .hgsub looks like: src/mylib = http://myserver/hg/mylib This should work, per my interpretation of the documentation: The first 'nested' is the path in our working dir, and the second is a URL or path to pull from. So, let's say I pull down fooproj to my home folder with: ~$ hg clone http://myserver/hg/fooproj foo Which pulls down the directory structure properly and adds the folder ~/foo/src/mylib which is a local Mercurial repository. This is where the problems begin: the mylib folder is empty aside from the items in .hg. With 2 seconds of investigation, one can see the src/mylib/.hg/hgrc is: [paths] default = http://myserver/hg/fooproj/src/mylib which is completely wrong (attempting a pull of that repo will give a 404 because, well, that URL doesn't make any sense). Logically, the default value should be what I specified in .hgsub or it would get the files from the repository in some way. None of the Mercurial commands return error codes (aside from a pull from within src/mylib), so it clearly believes that it is behaving properly (and just might be), although this does not seem logical at all. What am I doing wrong?

• Rails - difference between config.cache_store and config.action_controller.cache_store?

  - by gsmendoza

  If I set this in my environment config.action_controller.cache_store = :mem_cache_store ActionController::Base.cache_store will use a memcached store but Rails.cache will use a memory store instead: $ ./script/console >> ActionController::Base.cache_store => #<ActiveSupport::Cache::MemCacheStore:0xb6eb4bbc @data=<MemCache: 1 servers, ns: nil, ro: false>> >> Rails.cache => #<ActiveSupport::Cache::MemoryStore:0xb78b5e54 @data={}> In my app, I use Rails.cache.fetch(key){ object } to cache objects inside my helpers. All this time, I assumed that Rails.cache uses the memcached store so I'm surprised that it uses memory store. If I change the cache_store setting in my environment to config.cache_store = :mem_cache_store both ActionController::Base.cache_store and Rails.cache will now use the same memory store, which is what I expect: $ ./script/console >> ActionController::Base.cache_store => #<ActiveSupport::Cache::MemCacheStore:0xb7b8e928 @data=<MemCache: 1 servers, ns: nil, ro: false>, @middleware=#<Class:0xb7b73d44>, @thread_local_key=:active_support_cache_mem_cache_store_local_cache> >> Rails.cache => #<ActiveSupport::Cache::MemCacheStore:0xb7b8e928 @data=<MemCache: 1 servers, ns: nil, ro: false>, @middleware=#<Class:0xb7b73d44>, @thread_local_key=:active_support_cache_mem_cache_store_local_cache> However, when I run the app, I get a "marshal dump" error in the line where I call Rails.cache.fetch(key){ object } no marshal_dump is defined for class Proc Extracted source (around line #1): 1: Rails.cache.fetch(fragment_cache_key(...), :expires_in => 15.minutes) { ... } vendor/gems/memcache-client-1.8.1/lib/memcache.rb:359:in 'dump' vendor/gems/memcache-client-1.8.1/lib/memcache.rb:359:in 'set_without_newrelic_trace' What gives? Is Rails.cache meant to be a memory store? Should I call controller.cache_store.fetch in the places where I call Rails.cache.fetch?

• How can I return json from my WCF rest service (.NET 4), using Json.Net, without it being a string,

  - by Samuel Meacham

  The DataContractJsonSerializer is unable to handle many scenarios that Json.Net handles just fine when properly configured (specifically, cycles). A service method can either return a specific object type (in this case a DTO), in which case the DataContractJsonSerializer will be used, or I can have the method return a string, and do the serialization myself with Json.Net. The problem is that when I return a json string as opposed to an object, the json that is sent to the client is wrapped in quotes. Using DataContractJsonSerializer, returning a specific object type, the response is: {"Message":"Hello World"} Using Json.Net to return a json string, the response is: "{\"Message\":\"Hello World\"}" I do not want to have to eval() or JSON.parse() the result on the client, which is what I would have to do if the json comes back as a string, wrapped in quotes. I realize that the behavior is correct; it's just not what I want/need. I need the raw json; the behavior when the service method's return type is an object, not a string. So, how can I have my method return an object type, but not use the DataContractJsonSerializer? How can I tell it to use the Json.Net serializer instead? Or, is there someway to directly write to the response stream? So I can just return the raw json myself? Without the wrapping quotes? Here is my contrived example, for reference: [DataContract] public class SimpleMessage { [DataMember] public string Message { get; set; } } [ServiceContract] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)] public class PersonService { // uses DataContractJsonSerializer // returns {"Message":"Hello World"} [WebGet(UriTemplate = "helloObject")] public SimpleMessage SayHelloObject() { return new SimpleMessage("Hello World"); } // uses Json.Net serialization, to return a json string // returns "{\"Message\":\"Hello World\"}" [WebGet(UriTemplate = "helloString")] public string SayHelloString() { SimpleMessage message = new SimpleMessage() { Message = "Hello World" }; string json = JsonConvert.Serialize(message); return json; } // I need a mix of the two. Return an object type, but use the Json.Net serializer. }

• Binding a member signal to a function

  - by the_drow

  This line of code compiles correctly without a problem: boost::bind(boost::ref(connected_), boost::dynamic_pointer_cast<session<version> >(shared_from_this()), boost::asio::placeholders::error); However when assigning it to a boost::function or as a callback like this: socket_->async_connect(connection_->remote_endpoint(), boost::bind(boost::ref(connected_), boost::dynamic_pointer_cast<session<version> >(shared_from_this()), boost::asio::placeholders::error)); I'm getting a whole bunch of incomprehensible errors (linked since it's too long to fit here). On the other hand I have succeeded binding a free signal to a boost::function like this: void print(const boost::system::error_code& error) { cout << "session connected"; } int main() { boost::signal<void(const boost::system::error_code &)> connected_; connected_.connect(boost::bind(&print, boost::asio::placeholders::error)); client<>::connection_t::socket_ptr socket_(new client<>::connection_t::socket_t(conn->service())); // shared_ptr of a tcp socket socket_->async_connect(conn->remote_endpoint(), boost::bind(boost::ref(connected_), boost::asio::placeholders::error)); conn->service().run(); // io_service.run() return 0; } This works and prints session connected correctly. What am I doing wrong here?

• How to organize a large number of objects

  - by shane

  We have a large number of documents and metadata (xml files) associated with these documents. What is the best way to organize them? Currently we put them into a series of nested folders: /repository/category/date(when they were loaded into our db)/document_number.pdf and .xml We use the path as a unique identifier for the document in our system. This is more versatile than putting them all in a single flat folder. also it is independent from our database/application, so we can reload them in case of failure. Yet, it introduces some limitations. for example we can't move the files once they've been placed in this structure, also it takes work to put them this way. What is the best practice? How websites such as Scribd deal with this problem?

• Forwarding an email with python smtplib

  - by robbles

  I'm trying to put together a script that automatically forwards certain emails that match a specific criteria to another email. I've got the downloading and parsing of messages using imaplib and email working, but I can't figure out how to forward an entire email to another address. Do I need to build a new message from scratch, or can I somehow modify the old one and re-send it? Here's what I have so far (client is an imaplib.IMAP4 connection, and id is a message ID): status, data = client.fetch(id, '(RFC822)') email_body = data[0][1] mail = email.message_from_string(email_body) # ...Process message... # This doesn't work forward = email.message.Message() forward.set_payload(mail.get_payload()) forward['From'] = '[email protected]' forward['To'] = '[email protected]' smtp.sendmail(user, ['[email protected]'], forward.as_string()) I'm sure there's something slightly more complicated I need to be doing with regard to the MIME content of the message. Surely there's some simple way of just forwarding the entire message though? # This doesn't work either, it just freezes...? mail['From'] = '[email protected]' mail['To'] = '[email protected]' smtp.sendmail(user, ['[email protected]'], mail.as_string())

• WCF ReliableMessaging method called twice

  - by Brian

  Using Fiddler, we see 3 HTTP requests (and matching responses) for each call when: WS-ReliableMessaging is enabled, and, the method returns a large amount of data (17MB) The first HTTP request is a SOAP message with the action "CreateSequence" (presumable to establish the reliable session). The second and third HTTP requests are identical SOAP messages invoking our webservice method. Why are there two identical messages?

• Sending hidden fields via POST in iPhone in-app email

  - by Michael

  I'm letting my App's user send email from within the app to share some content on myserver. To do so I need to include a button with two bits of data and I want to use POST to keep it somewhat hidden. I've decided to add an html form using POST and two hidden fields in the email rather, like so: NSString *buttonCode = [NSString stringWithFormat:@"<form method='post' action='http://www.example.com/iphone/nifty.php'> <input type='hidden' name='dataOne' value='%@'> <input type='hidden' name='dataTwo' value='%@'> <input type='submit'value='Submit'></form>",dataOne, dataTwo]; NSString *emailBody = [NSString stringWithFormat: @"<b>%@ - %@</b>\n\n<HR WIDTH=200 SIZE=2 COLOR=#755f0f ALIGN=CENTER>\n Here is a email:<br><br>%@", dateString, timeString, buttonCode]; [picker setMessageBody:emailBody isHTML:YES]; I've confirmed by looking at the raw source of the email that the form is constructed correctly and I've copied and pasted it into a web page and it works. So here is the problem. When I click on the button in the received email (using apple's mail client) the dataOne and dataTwo variables don't get passed to my server. Is there a better way to do this or is the issue with my mail client?

• How to implement a web app with blazeds+java+flex+tomcat?

  - by ARYAD

  Hi, i'm doing a web app in flex blazeds and java, i installed the eclipse plugs for using WTP mixed project, i use the flex's server that uses an emulate of tomcat when i ran my flex service the web app got the datas, everythings is ok. the problem is when i copy the proyect with all files generated by flex in my tomcat or the blazeds's tomcat, it doesn't work, this is becasue i want to implement my app on a server the error is: "(mx.messaging.messages::ErrorMessage)#0 body = (Object)#1 clientId = (null) correlationId = "B425A2A7-7D12-A982-7779-8CCBF669413C" destination = "" extendedData = (null) faultCode = "Client.Error.MessageSend" faultDetail = "Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed: url: 'http://172.16.8.245:8400/IEC-BLAZEDS/messagebroker/amf'" faultString = "Send failed" headers = (Object)#2 messageId = "1CBC6020-0ED8-C4CC-3B77-8CCBF6D6621D" rootCause = (mx.messaging.events::ChannelFaultEvent)#3 bubbles = false cancelable = false channel = (mx.messaging.channels::AMFChannel)#4 authenticated = false channelSets = (Array)#5 [0] (mx.messaging::ChannelSet)#6 authenticated = false channelIds = (Array)#7 [0] "my-amf" channels = (Array)#8 [0] (mx.messaging.channels::AMFChannel)#4 clustered = false connected = false currentChannel = (mx.messaging.channels::AMFChannel)#4 initialDestinationId = (null) messageAgents = (Array)#9 [0] (mx.rpc::AsyncRequest)#10 authenticated = false autoConnect = true channelSet = (mx.messaging::ChannelSet)#6 clientId = (null) connected = false defaultHeaders = (null) destination = "ADEscenario" id = "7D92EDF2-CF62-9545-BA11-8CCBF6691E6B" reconnectAttempts = 0 reconnectInterval = 0 requestTimeout = -1 subtopic = "" connected = false connectTimeout = -1 enableSmallMessages = true endpoint = "http://172.16.8.245:8400/IEC-BLAZEDS/messagebroker/amf" failoverURIs = (Array)#11 id = "my-amf" mpiEnabled = false netConnection = (flash.net::NetConnection)#12 client = (mx.messaging.channels::AMFChannel)#4 connected = false objectEncoding = 3 proxyType = "none" uri = "http://172.16.8.245:8400/IEC-BLAZEDS/messagebroker/amf" piggybackingEnabled = false polling = false pollingEnabled = true pollingInterval = 3000 protocol = "http" reconnecting = false recordMessageSizes = false recordMessageTimes = false requestTimeout = -1 uri = "http://{server.name}:{server.port}/IEC-BLAZEDS/messagebroker/amf" url = "http://{server.name}:{server.port}/IEC-BLAZEDS/messagebroker/amf" useSmallMessages = false channelId = "my-amf" connected = false currentTarget = (mx.messaging.channels::AMFChannel)#4 eventPhase = 2 faultCode = "Channel.Connect.Failed" faultDetail = "NetConnection.Call.Failed: HTTP: Failed: url: 'http://172.16.8.245:8400/IEC-BLAZEDS/messagebroker/amf'" faultString = "error" reconnecting = false rejected = false rootCause = (Object)#13 code = "NetConnection.Call.Failed" description = "HTTP: Failed" details = "http://172.16.8.245:8400/IEC-BLAZEDS/messagebroker/amf" level = "error" target = (mx.messaging.channels::AMFChannel)#4 type = "channelFault" timestamp = 0 timeToLive = 0" i don't know why tomcat doesn't find the class of flex.messaging.endpoints.AMFEndpoint that is used for my-amf 'http://172.16.8.245:8400/IEC-BLAZEDS/messagebroker/amf'. all works well in the emulated server that flex has.

• WCF, ASMX Basic HTTP binding and IIS

  - by Brennan Mann

  Hello, I have been doing a lot of work with WCF "self" hosted applications. I recently was requested to write a web service where the calling client was a Linux based program named "WGET". I would like to use WCF instead of a traditional ASMX web service. The web service is returning a standard XML response. I am not sure of the underlining details between the two technologies but I know WCF is the proper route. I created a WCF service to be hosted in IIS ( using basicHttpBinding). 1.) Did classic ASMX web services ( standard HTTP POST/GET) use SOAP to return responses? I created an class from XSD for the web service response. What is really going on behind the scenes? Is there just special XML HTTP headers that know how to handle to response? Is the response not wrapped in SOAP? The traditional ASMX web service worked perfectly with the class I generated using the .Net "XSD" program. 2.) I want to use WCF for this service. Will using basicHttpBinding work? As I have read, that is the correct binding to use for ASMX clients. Does this use SOAP, standard HTTP headers, or something else? 3.) This is a dumb question because I have not done a lot of web service programming. I noticed on the ASMX default landing page there were examples for responses and code to invoke the functionality. When I create the same service using WCF, I had to create a client application to perform these tasks. Is there a way to expose the WCF endpoint like a classic ASMX service or is the WSDL the only route? As always, I really appreciate the feedback. Thanks, Brennan
