.NET Forum / ASP.NET / Web Services / February 2005An unexpected error occurred on a send
Hi, I'm trying consuming web services over SSL by an ASP .Net client without success. System Architecture: My Server side contains the following layers, starting from the client side: (Client side) WSD firewall Weblogic server. The webservices deployed On the weblogic Protocol: SSL. Version Information: Microsoft .NET Framework Version:1.1.4322.573; ASP.NET Version:1.1.4322.573 Symptoms 1. The handshake completed successfully, (taken from the MMC): “An SSL client handshake completed successfully. The negotiated cryptographic parameters are as follows. Protocol: SSL 3.0 Cipher: RC4 Cipher strength: 128 MAC: MD5 Exchange: RSA Exchange strength: 1024” 2. I’m getting the error message: WebException: The underlying connection was closed: An unexpected error occurred on a send.] emtv1.WebForm1.Button1_Click(Object sender, EventArgs e) in c:\inetpub\wwwroot\emtv1\webform1.aspx.cs:69 System.Web.UI.WebControls.Button.OnClick(EventArgs e) System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) System.Web.UI.Page.ProcessRequestMain() Facts: 1. Other client (java client) consumes the same services successfully. 2. Overriding the GetWebRequest method not solved the problem. What am I missing? Thanks in advanced, Can you look at the exception and post the error code?

You say that the Web Service can be called from a Java Client (is this a Windows Client?), so the first issue may not be the problem, but firstly, the COM component must be called from a STA thread, while your Web Service runs in a MTA thread. It may seem to work, but at least does not release the COM component properly. You will see that if you call an ActiveX exe, it will hang around (check in Task Manager) after the call completed. The second issue is security. You may want to use impersonation on the Web App you are calling the Web Service from, to see if it cures the problem. > Hi, > I'm trying consuming web services over SSL by an ASP .Net client without [quoted text clipped - 32 lines] > c:\inetpub\wwwroot\emtv1\webform1.aspx.cs:69 > System.Web.UI.WebControls.Button.OnClick(EventArgs e) System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePo stBackEvent(String eventArgument) > System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler > sourceControl, String eventArgument) [quoted text clipped - 8 lines] > > Thanks in advanced, Free MagazinesGet these publications absolutely FREE for up to 12 months.
