"404: Not Found" error when calling a web method

J

Jaime Stuardo

Hi all....

I have a web service method that when I call, I get the error:

The request failed with HTTP status 404: Not Found.

Line 58:
<System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://cursoaspnet1.com/webservices/ValidaUsuario",
RequestNamespace:="http://cursoaspnet1.com/webservices/",
ResponseNamespace:="http://cursoaspnet1.com/webservices/",
Use:=System.Web.Services.Description.SoapBindingUse.Literal,
ParameterStyle:=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)>
_
Line 59: Public Function ValidaUsuario(ByVal usuario As String,
ByVal pass As String, ByRef osigno As String) As Integer
Line 60: Dim results() As Object = Me.Invoke("ValidaUsuario",
New Object() {usuario, pass, osigno})
Line 61: osigno = CType(results(1),String)
Line 62: Return CType(results(0),Integer)

The line with the Invoke call is colored in red.

This is the webmethod definition for that function:

[WebMethod]
public int ValidaUsuario(string usuario, string pass, ref string osigno)
{
...
}

And this is the call:

Dim oWs As Alcahuet.AlcahuetNet = New Alcahuet.AlcahuetNet
Dim iAcceso = oWs.ValidaUsuario(strUsr, strPass, resigno)

I have added the web reference with the name of Alcahuet and when I connect
to http://localhost/AlcahuetNet/Alcahuetnet.asmx I get a list of methods.

Any help to solve this will be greatly appreciated

Thanks
Jaime

Use...

Dim iAcceso = oWs.ValidaUsuario(strUsr, strPass, ref resigno)

It may solve ur problem.

But with VB.NET I cannot use ref keyword to call a ByRef parameter. That is
only for C#

I cannot test it because when I see the method SOAP definition, using this
URL, http://localhost/AlcahuetNet/alcahuetnet.asmx?op=ValidaUsuario, at Test
area, this message is displayed:

"The test form is only available for methods with primitive types or arrays
of primitive types as parameters."

That's strange too, since the definition has string types, this way:

<ValidaUsuario xmlns="http://cursoaspnet1.com/webservices/">
<usuario>string</usuario>
<pass>string</pass>
<osigno>string</osigno>
</ValidaUsuario>

Maybe I would have to program the web service from scratch using the wizard
and then copy and paste each method bodies. Fortunately they are only 2.

The fact is that I downloaded this code as part of a tutorial. When I have
programmed web services using the wizard, I haven't had any problems on
invocation (using and not using primitive types).

One particularity with this web service is that all code is contained in the
ASMX file. The web services generated by the wizard contain a ASMX file with
only 1 line, and a the corresponding code behind, for example, ASMX.CS.
Maybe this is the problem, but according to the tutorial say, the webservice
should work.

Thanks
Jaime

Hi all....

I have a web service method that when I call, I get the error:

Line 61: osigno = CType(results(1),String)

The line with the Invoke call is colored in red.

This is the webmethod definition for that function:

[WebMethod]

And this is the call:

Dim oWs As Alcahuet.AlcahuetNet = New Alcahuet.AlcahuetNet
Dim iAcceso = oWs.ValidaUsuario(strUsr, strPass, resigno)

I have added the web reference with the name of Alcahuet and when I
connect to http://localhost/AlcahuetNet/Alcahuetnet.asmx I get a list
of methods.

Any help to solve this will be greatly appreciated

You can not use ref keyword in parameter list which u r passing it into the
web method. Becoz when I tried it by passing parameter with ref keyword and
running it through IE, i was not able to invoke the method. Than means, web
service method does support only primitive datatypes but not datatypes with
keywords.
if u delete ref keyword frm parameter list, everything should work fine.
Please try it once..

I cannot test it because when I see the method SOAP definition, using this
URL, http://localhost/AlcahuetNet/alcahuetnet.asmx?op=ValidaUsuario, at
Test area, this message is displayed:

"The test form is only available for methods with primitive types or
arrays of primitive types as parameters."

That's strange too, since the definition has string types, this way:

<ValidaUsuario xmlns="http://cursoaspnet1.com/webservices/">
<usuario>string</usuario>
<pass>string</pass>
<osigno>string</osigno>
</ValidaUsuario>

Maybe I would have to program the web service from scratch using the
wizard and then copy and paste each method bodies. Fortunately they are
only 2.

The fact is that I downloaded this code as part of a tutorial. When I have
programmed web services using the wizard, I haven't had any problems on
invocation (using and not using primitive types).

One particularity with this web service is that all code is contained in
the ASMX file. The web services generated by the wizard contain a ASMX
file with only 1 line, and a the corresponding code behind, for example,
ASMX.CS. Maybe this is the problem, but according to the tutorial say, the
webservice should work.

Thanks
Jaime

Can u plse provide me the WSDL file for the webservice u r calling?

-Deepak
But with VB.NET I cannot use ref keyword to call a ByRef parameter.
That is only for C#

Jaime

Use...

Dim iAcceso = oWs.ValidaUsuario(strUsr, strPass, ref resigno)

It may solve ur problem.

Hi all....

I have a web service method that when I call, I get the error:

The request failed with HTTP status 404: Not Found.

Line 58:
<System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://cursoaspnet1.com/webservices/ValidaUsuario",
RequestNamespace:="http://cursoaspnet1.com/webservices/",
ResponseNamespace:="http://cursoaspnet1.com/webservices/",
Use:=System.Web.Services.Description.SoapBindingUse.Literal,
ParameterStyle:=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)>
_
Line 59: Public Function ValidaUsuario(ByVal usuario As
String, ByVal pass As String, ByRef osigno As String) As Integer
Line 60: Dim results() As Object =
Me.Invoke("ValidaUsuario", New Object() {usuario, pass, osigno})
Line 61: osigno = CType(results(1),String)
Line 62: Return CType(results(0),Integer)

The line with the Invoke call is colored in red.

This is the webmethod definition for that function:

[WebMethod]
public int ValidaUsuario(string usuario, string pass, ref string
osigno)
{
...
}

And this is the call:

Dim oWs As Alcahuet.AlcahuetNet = New Alcahuet.AlcahuetNet
Dim iAcceso = oWs.ValidaUsuario(strUsr, strPass, resigno)

I have added the web reference with the name of Alcahuet and when I
connect to http://localhost/AlcahuetNet/Alcahuetnet.asmx I get a
list of methods.

Any help to solve this will be greatly appreciated

Thanks
Jaime
