Can't get the Web Tier\Custom Parameters demo to work

rbuser

Hi,

I'm using RB Server in Delphi 7 on Win XP Pro

After I click the Submit Form button on the Custom Login Form, on the
following web page (http://localhost:8081/rbWebDebug.CoRBWebDebug/Login) I
get two frames with "Action Cancelled".



Am I overlooking something?

Make sure that the WebTier is configured properly for your installation. And
IIS needs to be running.

Can you run the Web Debugger demo?

Referring to Web Tier\Customer Parameters demo: In the three Page
Producers,
the HTMLFile property is C:\TeamSource\RBServer Examples\Web Tier\Custom
Parameters\.....
I presume the path must be changed to: C:\Program
Files\Borland\Delphi7\RBServer\Demos\Web Tier\Custom Parameters
I started C:\Program Files\Borland\Delphi7\RBServer\Demos\Servers\04. Custom
Parameters\rbServer.exe, and the Web App Debugger, Clicked on the default
URL, supplied my name and password on the next page and clicked on Submit
Form.
But on the following web page, with address
http://localhost:8081/rbWebDebug.CoRBWebDebug/Login, displays two frames
with "The page cannot be displayed"

1. No path change is required. Please see the WebModule.OnCreate
event-handler, the file names are dynamically resolved to use the
application file path.

2. Check the following:

- make sure that you have a web server running (IIS or Apache). The HTML
page that displays the frames has references to other HTML pages
(TreeView.HTML and ListView.HTML) These must be loaded via the web server.
Same with image references etc.

- from the Web Browser perform a View | Source on the frame page and check
the URL for the TreeView.HTML and ListView.HTML. Make sure they are correct
and that the web server has security access to the directoy.

- Use Windows Explorer to check the web cache and make sure the
Treeview.HTML and ListView.HTML are generated to the proper directory.
Adjust the WebTier settings if needed.

O.K, It's working now. I did the following: I created a new web server
application as a ISAPI/NSAPI Dll and, as the WebTier example, implemented it
under IIS then the Web App Debugger work fine.

I also got a way to let an IntraWeb application interface with this WebTier
Dll. See code snippet appearing below:
=====================================================
unit Main;

interface

uses
Classes, SysUtils, IWAppForm, IWApplication, IWColor, IWTypes, ppComm,
rsWebTier, Controls, IWVCLBaseControl, IWBaseControl, IWBaseHTMLControl,
IWControl, IWCompButton, IWCompEdit, IWCompLabel, IWCompListbox;

type
TfrmMain = class(TIWAppForm)
btnReport: TIWButton;
cbxColor: TIWComboBox;
lblAccountName: TIWLabel;
lblAccountPassword: TIWLabel;
lblColor: TIWLabel;
edtName: TIWEdit;
edtPassword: TIWEdit;
procedure btnReportClick(Sender: TObject);
public
end;

implementation

uses IWBaseForm;

{$R *.dfm}


procedure TfrmMain.btnReportClick(Sender: TObject);
const
AIPOptions: string =
'toolbar=no,status=no,menubar=yes,scrollbars=yes,resizable=yes,location=no,directories=no,width=780,height=580';
var
AIPURL: string;
begin
AIPURL := 'http://localhost/myWebTierParams/myWebTierParams.dll/Login?' +
'AccountName=' + edtName.Text + '&' +
'AccountPassword=' + edtPassword.Text + '&' +
'Color=' + cbxColor.Items[cbxColor.ItemIndex];
AddToInitProc('NewWindow("' + AIPURL + '", "Agenda", "' + AIPOptions
+'");');
end;

initialization
TfrmMain.SetAsMainForm;

end.
=====================================================

It feeds the name and password and color to first window and take the user
directly to the second window.

So it's a matter of IntraWeb talking to the WebTier and Webtier talking to
the Windows Services.

I don't know if there is a better or a more elegant way to do it but at
least I have now something to work with.

By the way, I wondered if one can use the rsClientReport and
rsClientReportExplorer directly in a IntraWeb application or are they
bounded to a Windows application?

1. IntraWeb

Looks good

2. TrsClientReportCatalog

This is a non-visual component that can be used to retrieve information
about the available reports on the server. It is used by the
ClientReportExplorer.

For examples, see RBServer\Demos\Clients\ClientReportCatalog\Dynamic List
and Dynamic Menu. The TrsClientReportCatalog is documented in the
RBServer.hlp.

The TrsClientReportExplore creates a TForm, so I you should not use it in a
web app unless you avoid creating the form. But I think using
TrsClientReportCatalog should do what you need - get the available reports
and then you can build the html from there.

3. TrsClientReport.

TrsWebTier uses TrsClientReport internally to retrieve autoseach info and
page objects from the server. However, all of the HTML creation (or PDF
creation or whatever) is done by the TrsWebTier class and there is quite a
bit of other complex processing/caching/session management/etc. performed as
well. The pages are generated incrementall upon demand - which also adds
complex (but speeds performance greatly).
