Genero Application Server (GAS) is an engine that delivers Genero
applications. It creates relationships between various front-ends (the Genero Desktop Client Active X,
the Genero Java Client and the Genero Web Client) and the DVMs which run the
applications. The GAS also manages a pool of DVMs for Web Services applications.
See also Front-ends and Extensions.
This Application Server is interfaced with a Web Server to handle requests
from the Internet. Communication between the Web Server and the GAS daemon is
handled by the Application Server Connector.Back to the

With the support of the http protocol, the GAS daemon provides a direct connection
for access to applications without using a Web Server. During the development phase,
you can exclude the Web Server from your development architecture.GAS simplifies the deployment phase by taking care of the connection
to the applications. No software installation or configuration is needed
on the end user's side; a simple browser is all that is required to access the program.

The GAS connector sends requests from the Web Server to the correct GAS
daemon.
Several GAS daemons can be configured to load balance the requests. The
configuration of GAS daemons is
done in the connector.xcf file (the GAS connector
configuration file), found in the script
directory of the Web Server.
There are two kinds of connectors: CGI and ISAPI. While they use different technologies,
they both play the same role and use the same GAS connector configuration file.
The ISAPI connector is only available on Windows platforms.

The Genero Application Server can serve your applications with these various
front-ends and extensions.
- Genero Desktop Client ActiveX
Genero Desktop Client Active X (GDC/AX) allows you to run the Genero
Desktop Client via a Web site or http address. The first time you access the
Client in Active X mode, the GDC/AX software installs itself on your client
machine and creates a shortcut in Windows Start Menu. The GDC can then be
executed from the web page or directly using the shortcut.
For more information and installation instructions, refer to the Genero
Desktop Client Manual.
- Genero Web Client
The Genero Web Client (GWC) allows you to deliver Genero applications in
a Web browser, without having to install any software on the client machine.
Starting with 2.11, the GWC is included in the installation for the GAS.
When working with the GWC, scan the GWC-specific sections in the Table of
Contents.
For a more detailed overview of the GWC, see What
is the Genero Web Client?
- Genero Web Services Extension
The Genero Web Services Extension (GWS) allows you to implement Web
services. Web services are a standard way of communicating between
applications over the Internet or Intranet. A web service can be a server
that exposes services, or a client that consumes a service.
For more information and installation instructions, refer to the Genero
Web Services Extension Manual.
- Genero Java Client
Genero Java Client (GJC) is a graphical front-end for delivering Genero
applications. It is written in Java and can be run under any operating
system which supports J2SE Java Runtime Environment (JRE) version 1.4.2 or
higher. GJC can also be embedded into an HTML page thanks to an Applet,
which will work on any browser that supports Java Plug-in technology with a
1.4.2 or higher J2SE Java Runtime Environment.
For more information and installation instructions, refer to the Genero
Java Client Manual.
