Browser connects to WCF service but not my WCF client. What can be the reason? -

-

On the production server (Windows Server 2003 SP2), I can connect to a remote WCF service with Internet Explorer 8: When I browse the URL (where my service listens) I see the expected notification page of the service I Internet Connection setting in Explorer specifies only "auto address", proxy settings are disabled.

If I connect to the same server on the same console console application (which is created with WCF) the same WCF service is telling me that no endpoint is available but not available.

WCF Client Configuration: 

  & lt; Configuration & gt; & Lt; System.serviceModel & gt; & Lt; Binding & gt; & Lt; WsHttpBinding & gt; & Lt; Binding name = "WSHttpBinding_IMyService" closeTimeout = "00:01:00" openTimeout = "00:01:00" receiveTimeout = "00:10:00" sendTimeout = "00:01:00" bypassProxyOnLocal = "false" transactionFlow = " False "hostNameComparisonMode =" StrongWildcard "maxBufferPoolSize =" 524288 "maxReceivedMessageSize =" 65536 "messageEncoding =" text "textEncoding =" utf-8 "useDefaultWebProxy =" true "AllowCookies =" false "& gt; & Lt; ReaderQuotas maxDepth = "32" maxStringContentLength = "8192" maxArrayLength = "16384" maxBytesPerRead = "4096" maxNameTableCharCount = "16384" /> & Lt; Trusted session ordered = "true" idle time = "00:10:00" enabled = "wrong" /> & Lt; Safety Mode = "None" & gt; & Lt; Transport Client Credential Type = "Windows" Proxy Credential Type = "None" realm = "" /> & Lt; Message Client Credential Type = "Windows" Conversation ServiceCreation = "true" /> & Lt; / Safety & gt; & Lt; / Binding & gt; & Lt; / WsHttpBinding & gt; & Lt; / Binding & gt; & Lt; Customers & gt; & Lt; Endpoint address = "http://www.domain.com/Service.svc" binding = "wsHttpBinding" bindingConfiguration = "WSHttpBinding_IMyService" contract = "Service.IMyService" name = "WSHttpBinding_IMyService" /> & Lt; / Customer & gt; & Lt; /system.serviceModel> & Lt; Configuration & gt;

With these settings, I can communicate successfully with remote service from my development machine.

Searching for other options I found out that I have Internet Explorer proxy settings: 

   & Lt; / DefaultProxy & gt; & Lt; /system.net>

It was not working and I'm not sure that I really understand this setting correctly. (I hope WCF customers connect to the "auto-find" installation of Internet Explorer and then to serve like IE installed in the same way.)

I also use useDefaultWebProxy < There was no success in binding configuration between / code> correct and false.

Now I am asking for help, what can I do? Which setting might be incorrect or unavailable?

Edit:

In the heap InnerException is saying:

  • System.Net.WebException : The connection to the remote server could not be established
  • System.Net.Sockets.SocketException : The host responded after a fixed time period Not given or the connection was not answered by the connected host, because the connection failed. & Lt; Proxy utility systemdefault = "true" /> (The documentation says: It will pick up Internet Explorer settings but it does not work.) Finally the customer gave me a solid proxy address and I have compelled my client configuration in the following manner:

    • changed: useDefaultWebProxy = "false" (instead of true )
    • Added: proxyAddress = "http : //10.20. 30.40: 8080 " (Edit 2: IP address not only! Prefix with http: // is important! Otherwise See the follow-up question below.)

    With this WebException and SocketConnection disappeared and the client service seems to be connected, but I now have the first problem when the first Calling service operation I will put it in a new question.

    Edit: Here is the follow-up question:

    Edit 2: Answer- above question with proxy address with The http is important for the prefix. (My answer has changed now)

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's...

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa...

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k])
