We have 1. Written and tested a WebService in VB.Net. 2. Saved the WSDL and edited it to make it work 3. Used 'Generate from WSDL' to create the classes 4. Built a Visual force page.
And we get this error:
Visualforce Error
Help for this Page
System.CalloutException: IO Exception: Read timed out
Class.alphaIndexCoUk.CNetWebServiceSimpleSoap.HelloWorld: line 30, column 1 Class.alphaIndexCoUkSample.__sfdc_hellow: line 8, column 1
Looking at the Log our web service generates, Salesforce is not connecting to the webservice.
The code used is as follows:
1. ASMX FILE
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
' <System.Web.Script.Services.ScriptService()> _
<System.Web.Services.WebService(Namespace:="http://alpha-index.co.uk/")> _
<System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ToolboxItem(False)> _
Public Class CNetWebServiceSimple
Inherits System.Web.Services.WebService
<WebMethod()> _
Public Function HelloWorld() As String
Return "Hello World"
End Function
End Class

public class alphaIndexCoUk {
public class HelloWorld_element {
private String[] apex_schema_type_info = new String[]{'http://alpha-index.co.uk/','true','false'};
private String[] field_order_type_info = new String[]{};
}
public class HelloWorldResponse_element {
public String HelloWorldResult;
private String[] HelloWorldResult_type_info = new String[]{'HelloWorldResult','http://www.w3.org/2001/XMLSchema','string','0','1','false'};

);
response_x = response_map_x.get('response_x');
return response_x.HelloWorldResult;
}
}
}
4. Custom Apex class
public class alphaIndexCoUkSample {
public string hellow{
get{
alphaIndexCoUk.CNetWebServiceSimpleSoap dns = new alphaIndexCoUk.CNetWebServiceSimpleSoap ();
return dns.HelloWorld();
}
set;
}
}
5. Visual force page to show HelloWorld
<apex:page controller="alphaIndexCoUkSample">
<apex:form ><apex:inputText value="{!hellow}"/></apex:form>
<!-- Begin Default Content REMOVE THIS -->
<h1>Congratulations</h1>
This is your new Page
<!-- End Default Content REMOVE THIS -->
</apex:page>
All the web service does is return 'Hello World' and record the call to a log file. Clicking on [Test Hello World] runs the Web Service And clicking on [View Hello World Log] displays the last log entry (we used this to see if Salesforce was reaching our web service)
We are trying to extract a PDF Document object from Salesforce. We've managed to get the document, but seem to be getting stuck with the encoding. Please see the VB code below.
It does create a PDF file, and it even has the correct number of pages, but all the pages are blank.
Comparing the original PDF file, and the one we are creating and a text editor, we can see the character coding is slightly different:
The 'good' PDF starts with: %PDF-1.4
%âãÏÓ
The 'bad' one is: %PDF-1.4
%âã�Ó
We've tried all sorts of decoding but are completely stuck. Anyone any ideas?
Thanks - Pablo
