No content provider for request

rbuser

Hello, again,

While trying to implement a server with parameters i'm getting a problem
using the rsWebTier.
My 'regular'-client, derived from the demo app with parameters works fine.
I'm able to check what user logged in and i'm showing only the 'allowed'
reports to that user.

When doing the some over a WebTier (testing as a WebApp-exe or ISAPI-dll),
the login works (i'm using codesite to 'monitor' my webserver) but then i'm
getting this error on the WebTier

EWebTierError TrsWebTier.GenerateContent: No Content provider for Request

Any suggestions ???

The error you are receiving indicates that either the content parameter
is missing or there is no content provider registered for the specified
content type.

I just wrote the following article that explains the ContentProvider
architecture:


---------------------------------------------
Tech Tips: WebTier Content Providers
---------------------------------------------

The WebTier architecture dispatches WebRequests to appropriate
ContentProviders. ContentProviders are responsible for processing a
request and generating a response.

Requests sent from a web browser to the webtier must include a content
parameter. For example:

content=Viewer


In your WebTier application you can check this by checking
TrsWebRequest.ContentType (or by checking
TrsWebRequest.ContentParameters['content']). Either syntax checks the
same parameter.


RB Server ContentProviders
---------------------------

Viewer - web report previewer
Explorer - web report explorer
SearchForm - web autosearch form
Soap - web proxy for Thin Client applications using HTTP
PDF - PDF report provider for Waler or Pragnaan, if registered

rbuser

I've added the code aWebRequest.ContentType = 'Viewer', but now i'm getting
the next error

TrsWebContentProviderViewer.ValidaterequestParameters : No volume name
specified.

I'm sure the server is running, when connection with a thin-client to the
same server it works fine (program copied from the thin-client-parameters
demo).

Perhaps this will help......

Tech Tips: How can I request that the webtier
execute a specified report?
---------------------------------------------


Question:
---------

Without using the Web ReportExplorer, how can I request that the webtier
execute a specified report?


Solution:
---------

The webtier processes requests for web content. These requests consists of

1. The URL for the webtier

example: http://127.0.0.1/rbWebPub/report.dll


2. A parameter specifying the content type.

example: content=viewer

{note: content=viewer, is used to request report viewer content.}


3. Additional parameters that are specific to the content request.

volume=Report Forms (the volume name)
Name=Basic\Biolife Table (the full path name to the report)
frameset=1 (show the framset with the toolbar etc., this is required)


Use a web browser to access the webtier demo that displays the report
explorer.

Notice that when you place the mouse over a report in the report explorer
that the status bar in IE shows the url plus some params. That is the string
required to run the report on the web tier.

Example:
http://127.0.0.1/rbWebPub/report.dll?content=viewer&volume=Report
Forms&name=Basic\Biolife Table&framset=1


So the parameters here are

content=viewer (type of content is report viewer)
volume=Report Forms (the volume name)
Name=Basic\Biolife Table (the full path name to the report)
frameset=1 (show the framset with the toolbar etc., this is required)
