I have uploaded a sample project to the binaries newsgroup that
demonstrates how to connect to a web service using EWB.

Hope it helps.

thanks a lot for sharing!

I tested project1.html with my three browsers
(see screenshot: http://h8.abload.de/img/ewbd859z.png)

Google Chrome V15.0.874.121 (on the left side):
 There are no captions and after clicking the button an error-message appears

IE 9 (in the middle):
 Everything seems to be OK

Firefox 7.0.1 (on the right side)
 After clicking the button an error-message appears

Greetings ... Peter

Sorry for my weird english

I'm looking into the caption issue.  As for the error, see below.

<< Firefox 7.0.1 (on the right side)

FireFox (and I assume WebKit also) has a "same-source-domain" policy for
AJAX requests.  What this means is that you cannot execute AJAX requests
from an application that has been loaded directly from a file.  IE doesn't
have this restriction.

This is also why the next build will have a local web server built into the
IDE, so you can easily test against other browsers using localhost, and can
send debug output from those browsers to the IDE "Messages" window.

Hi,

I tried to add some exception handling to confirm what the error was but
it throws an error on the line:

   on E : Exception do

Complaining that it does not know what an Exception is.

As a non Deplhi programmer I would gladly except an help as to what I
have done wrong here. (My Delphi book is on order

Complete code part is shown below
====================================
 try
   ServerRequest1.URL :=
'http://cypher1.co.uk/WebService/Cypher1Data.asmx';
   ServerRequest1.Method := rmPost;

   ServerRequest1.RequestContent.Clear;
   ServerRequest1.RequestContent.Add('<?xml version="1.0"
encoding="utf-8"?>');
   ServerRequest1.RequestContent.Add('<soap:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="'" name="http://schemas.xmlsoap.org/soap/envelope/">'">http://schemas.xmlsoap.org/soap/envelope/">');
   ServerRequest1.RequestContent.Add('<soap:Body>');
   ServerRequest1.RequestContent.Add('<UserLogon xmlns="Cypher1Data">');
   ServerRequest1.RequestContent.Add('<userName>'+ UserNameEdit.Text +
'</userName>');
   ServerRequest1.RequestContent.Add('<userPassword>' +
UserPasswordEdit.Text + '</userPassword>');
   ServerRequest1.RequestContent.Add('</UserLogon>');
   ServerRequest1.RequestContent.Add('</soap:Body>');
   ServerRequest1.RequestContent.Add('</soap:Envelope>');

   ServerRequest1.RequestHeaders.Clear;
   ServerRequest1.RequestHeaders.NameValueSeparator := '=';
   ServerRequest1.RequestHeaders.Add('Content-Type = text/xml;
charset=utf-8');
   ServerRequest1.RequestHeaders.Add('Content-Length =' +
IntToStr(Length(ServerRequest1.RequestContent.Text)));
   ServerRequest1.RequestHeaders.Add('SOAPAction =
"Cypher1Data/UserLogon"');

   ServerRequest1.Execute;
   except
   on E : Exception do
     begin
       ResponseEdit.Text := E.ClassName + ' : ' + E.Message;
     end;
   end;

Try something like this :

   try
      //... you code here ...
   except
      ON E:TError do
         ResponseEdit.Text := E.ClassName + ' : ' + E.Message;
   end;

Sorry - copy pasted code from your sample and you need to remove the
classname as there is no such thing (e.message is still ok):

try
  //... you code here ...
except
  ON E:TError do
    ResponseEdit.Text := E.Message;
end;

Hi Raul,

Thanks for that, compiles now but the E.Message appears to be blank.

I changed it to ResponseEdit.Text = 'Error:' + E.Message

and it only shows as Error:

Chris,

As far as I can tell, it's purposefully left blank for this particular
exception - FireFox just goes "Duh !" and leaves it at that, leaving one to
spend an hour trying to figure out exactly what the hell is going on.
