BUG: You receive a "Server error" error message if you try to invoke a Web service that has a name that contains a space character by using Visual C++ .NET
You may use Microsoft Visual C++ .NET to create an XML Web
service that contains a space character (" ") in its name. When you try to call this XML
Web service, you receive an error message that is similar to the following:
Server Error in '/my webs' Application.
The resource
cannot be found. Description: HTTP 404. The resource you are looking for (or
one of its dependencies) could have been removed, had its name changed, or is
temporarily unavailable. Please review the following URL and make sure that it
is spelled correctly. Requested Url: /my webs/my+webs.asmx
Version
Information: Microsoft .NET Framework Version:1.1.4322.573; ASP.NET
Version:1.1.4322.573
The word "Url" is not capitalized correctly in this error message.
If you name a Web service and if that name
contains a space character (" "), during run time the space character is
not escaped and the space character is replaced by a plus sign ("+") instead of
by "%20". The plus sign ("+") value instead of a space character generates an address that either
does not exist or may be irrelevant for that corresponding
Web service or method.
To work around this problem, use any of the following
methods:
- Do not use space characters when you name a Web
service. Use a name for the Web service that does not contain any space characters (" ").
- Replace "+" with "%20" in the Address bar when you address the Web service.
To do this with the example that is described in the "More Information" section of this article, follow these steps:
- After you click the HelloWorld link, a Web browser window opens with an address in the Address bar.
- Replace the following line in the Address
box
http://localhost/My%20Web2/my+webs.asmx?op=HelloWorld
http://localhost/My%20Web2/my%20webs.asmx?op=HelloWorld
Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section of this article.
Steps to reproduce the behavior
- Start Microsoft Visual Studio .NET.
- On the File menu, point to
New, and then click Project. The New
Project dialog box appears.
- Under
Project Types, click Visual C++
Projects, and under Templates, click ASP.NET
Web Service.
Note In Microsoft Visual Studio .NET 2002, under
Templates, click Managed C++ Web
Service. - In the Name box, type my webs, and then click
OK.
- Press F5 to run the application. The mywebsClass
Web Service Web page appears.
Note In Microsoft Visual Studio .NET 2002, the Class1 Web
Service Web page appears. - On the Web page,
click the HelloWorld link.
You may notice the error message that is mentioned in the "Symptoms"
section of this article.
