Everything looks good but Wireshark shows 505 coming back (HTTP/1.1 505 HTTP Version Not Supported). Tomcat admin sites post that says .NET has a known bug where HTTP 1.1 is handled correctly:
[URL]
To me it seems like a Tomcat issue because I trust that if this was a Microsoft issue they would've released a patch by now, but regardless, he thinks that if I change to HTTP 1.0 the problem will resolve itself. I do not see any property in HttpClient or HttpClient.TransportSettings to control this.
Has anyone ran into this before or know how to set the HTTP version with the REST API?
I have looked at nearly every single WCF Rest PUT/POST issues on SO here and have still been unable to determine why I am unable to PUT or POST to my web service but am able to call a test GetTime method via GET. This particular service exchanges custom credential information (username, password and some other information) for a token. This token information is encrypted and added to the header of subsequent requests to other web services so that username/passwords don't have to be passed around everywhere. All web service calls are still treated as stateless, but require this auth header information rather username/passwords to access secured service operations.

I have also checked in IIS 7 the handler mappings for *.svc and checked that 'all verbs' are enabled.
After going through all the codes I was given, I've come up with the following code below. The only problem now is connecting the upload button to the browse and then display the file and store in the image folder.
Is there any way an ASP.NET application can run on a Tomcat Server? The company I work for doesn't want me to install IIS, since, according to them, it is prone to hacking. Tomcat Server version that they're using is 4.1.31, and also, they're using J2SE 1.4.
I've written some code using the REST starter kit and it works fine on my development machine. However, when I upload it to our server the page gives me the following error message... CS1684: Warning as Error: Reference to type 'System.Runtime.Serialization.Json.DataContractJsonSerializer' claims it is defined in 'c:WINNTassemblyGAC_MSILSystem.ServiceModel.Web3.5.0.0__31bf3856ad364e35System.ServiceModel.Web.dll', but it could not be foundI've removed code line by line and it appears that the following line of code is triggering the error...HttpContent newOrganizationContent = HttpContentExtensions.CreateXmlSerializable(newOrganizationXml);Really haven't got a clue how to fix it. I assumed it might be because it needs a newer version of the framework to run, but looking in IIS it says it's running version 2.0.50727 which I think is the lates version because it says that even when we're using framework 3.5
While working with LINQ to ENTITIES I see that there is only a way to use stored procedure that is returning one entity only, or a view that is a join of two entities.
But what if I need in ASPX page to get two tables that there is NO connection between them, no join can be done between them at all.
I have one Stored Procedure that return the two tables, but entities don't support this right now.
I can split them to two Stored Procedure and call each of them separately.
I have a application with a 3-tier architecture. Onclick event of a button, I am calling a method in my code behind file. This method is defined in the Interface( Interface resides in my Business layer) and the implemtation of this method is given in the Data access layer.
The business layer and DAL are on different projects. I have compiled the entire solution and it complies OK. Now when I try to click the button I get the error:
"The method 'doInsertCust' was not found on the interface/type 'My.Type, MyTypeLibrary, Version=1.0.2371.15203, Culture=neutral, PublicKeyToken=null'.".
Note that I have already build the Business layer and DAL and the respective DLL gets automatically refreshed.

I upgraded a Website to use ASP.NET 4.0, from 3.5. This involved setting it up on a different server, with the same hosting company. I'm using a shared hosting plan on Windows Server 2008.
Since migrating, it gives an error message when I try to login to the site:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I'm using the same connection string as I did in the old version, which always worked. I also changed the permissions for the database to allow connections from the redeployed Website, via the host's control panel.
I have searched the web.config, and the source for the site, and I haven't been able to find a connection string that looks incorrect.
I've contacted the host about it, in case it is a configuration issue on their side.
When ever I try to connect to server through Microsoft sql server management studio express then an error is generated saying that
Cannot connect to .//SQLEXPRESS
Additional Information
A network related or instance specfic error occured while connecting to SQL server. The server not found or not accessible verify that instance name is correct and that SQL server is configured to allow remote connections.(Provider: Named Pipes Provider, error 40-could not open connection to SQL server )(Microsoft SQL server, Error:53)
My website is [URL] (access there to see error, please) When I was testing in VS2010, it was connecting to the DB because I set permissions READ/WRITE on my computer to ALL. If I put restrictions, VS2010 couldn't just connect to them. Well, I deployed my DB on the server of my website, and I'm not able to access it.
My connection string:
connection = New SqlConnection("Data Source=.SQLEXPRESS; Integrated Security=True;AttachDbFilename=|DataDirectory|Visitas.mdf")
I think I'm getting these errors because my server hasn't permission to access the database.
I am facing some problem while uploading excel sheet upload and connecting it to dataset. The Code works fine in local machine but on website its showing following error.

I have a WCF service hosted on win 2008 server. I'm using WAS to expose a named pipe endpoint on the service and have a client website that consumes the service. When i hit the website from a remote machine i get the following error:The pipe name could not be obtained for the pipe URI: Access is denied. (5, 0x5)Now if i hit the website ON THE SERVER it's being hosted from, using localhost in the url, it works fine. Clearly there is something i don't understand about what the named pipe endpoint is looking for. I tried running a trace from my service, but there is no output because the call doesn't even get to the service.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

what am I supposed to do to make this connection work! I have always done it in dreamweaver with no problems, but I have to use Visual Web Developer for this project.
I need to call a Rest service but would like to do so without having to redirect. Here is my dilemma. The Rest service we are trying to integrate offers the option to sign up for a subscription but does not allow us to upgrade an existing subscription. So if a user wants to upgrade an existing subscription we have to first cancel and then have the user sign up for a brand new subscription. I don't know how I can make this so it flows nicely in my code. I ideally I would like to do something like this
User decides to upgrade
Click upgrade button
Existing account is being cancelled, if cancellation was successful
New account is being created
How can I do this with a Rest service? Here is a sample URI/URL
Could anybody give me some ideas how to make this work in an elegant manner. We thought we could keep the old subscription and then just sign the user up for a new subscription for the difference of the money. For example the first subscription would be 2.95 and the second one would be 2.00 which would amount to a subscription of 4.95. I think it is not elegant and the user would see 2 charges on the credit card, weird, I think. Since I don't know much about Rest maybe there is a way that this can be solved.
When i compile my vs2008 solution which is a web application in debug mode i keep getting message box displayed which says that it cannot connect "whatever.designer.cs". Can
I want to implement a custom authentication in my application using the basic authentication schema. I've configured it in the Web.config and enabled the basic authentication in the IIS, but when I try to open the service in the browser... appears a login dialog... what do I have to put ther? Besides, I want to control the authentication, I mean, I want to check whom is allowed in my custom list... where is it looking now?
When I use the WebRequest class, I'm getting a "401 - Unauthorized":
req = WebRequest.Create("http://localhost/RESTfulService/Service1.svc/Test"); req.Credentials = CredentialCache.DefaultNetworkCredentials; WebResponse res = req.GetResponse();
What do I have to do for implement a custom basic authentication? (I cannot use membership providers).
I created an ASP.NET REST service (using WCF) and access it through one of my .aspx page. the problem is that when I publish (precomile) my code to the web server, I get an error :
"ThunServ not defined" in the Javascript console of my browser.
I have developed an rest enable wcf service by using the following link
[URL]
Now I want to know is there any difference between rest enabled wcf service (or restful web service) & rest web service ? If there is any difference then what is that ? If there is difference the can you provide me any link (which represents steps visually as in above link) through which I can develop rest web service ?
Background: I use SQL server 2005 developer edition and visual studio 2008. Visual studio 2008 is running on a local machine with Vista business edition. SQL server is running on a remote server using Windows server 2003. Both computers are within the same domain.
Problem: First, I used the server explorer to connect to the SQL server. Everything works as desired. Then I write code to do the same thing. I keep getting the following error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid)
However, I used the exactly identical connection string as the one used in the server explorer. So connection string should not be the problem. In addition, I tried the test code in MSDN, which tells whether my domainusername can flow the network. It turns out the user name is fine. I also went to the SQL server management studio and found the login for my computer is NVCWeihao while my computer login name is NVCweihao. I am wondering if this uppercase letter really affects the connection.
The problem i have would be im getting - 'System.Data.SqlClient.SqlException: Login failed for user 'discountb1'.' error message. my connection string in ASP was the following
Well it's finally time to stop ignoring my unit's need for reports. I keep coming to dead ends. I gave up the crystal reports idea, and ssrs seems a little easier. Now the problem is that I'm creating a report locally on my laptop, then will change the connection string, upload it to my server and have it run against an identical database on the server.
I'm using SQL Server Express locally, and when I try to create a dataset (using the wizard), I can see the tables, but when I try to add one, I get an error message "Could not retrieve schema information for table or view". I looked up this error and there isn't much useful info on it. I guess it some bug when trying to use SS Express? Is there a work around for this? Can I create the report programmatically? Should I use a different kind of reporting service?
We have a MOSS 2007 custom web part based on a user control that queries a database cluster. When the connection to the database is made, we regularly experience the error below and have had to create a work-around in the code to retry the connection. We have 3 environments - development, staging and production; the error only occurs in production. The difference in the production environment is it is a farm with 3 WFEs and a SQL cluster, where development and staging are single machine instances. All are MOSS 2007 & SQL Server 2008. We cannot find what is causing this issue and I'm hoping someone else has experienced a similar problem and knows the cause.
This is the error that occurs frequently when the query is executed: System.Data.SqlClient.SqlException: A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.) at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParserStateObject.WriteSni() at System.Data.SqlClient.TdsParserStateObject.ExecuteFlush() at System.Data.SqlClient.TdsParser.TdsExecuteRPC(_SqlRPC[] rpcArray, Int32 timeout, Boolean inSchema, SqlNotificationRequest notificationRequest, TdsParserStateObject stateObj, Boolean isCommandProc) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method) at System.Data.SqlClient.SqlCommand.ExecuteScalar() at [Our Namespace.OurMethod](String someParam)
More than one method will generate this, but this is typical code, note the retry work-around: public static DataTable OurMethod(string someParam) { const string query = "sp_OurStoredProcedure"; var resultsTable = new DataTable(); var connection = new SqlConnection { ConnectionString = OurDatabaseConnection }; var command = new SqlCommand(query, connection) { CommandType = CommandType.StoredProcedure }; var dataAdapter = new SqlDataAdapter(command); var retry = 5; SqlConnection.ClearPool(connection); while (retry > 0) { try { command.Parameters.Clear(); command.Parameters.AddWithValue("@someParam", someParam); connection.Open(); dataAdapter.Fill(resultsTable); retry = -1; } catch (Exception ex) { retry--; if (retry <= 0) { LogError("Exception: DataAccess:OurMethod: *RETRIES EXCEEDED* " + ex, "error"); } else { SqlConnection.ClearPool(connection); LogError("Exception: DataAccess:OurMethod: ATTEMPTS REMAINING " + retry + ". " + ex, "warning"); } } finally { dataAdapter.Dispose(); command.Dispose(); connection.Dispose(); } } return resultsTable; }
