Configure for the Web client

To display web applications or to run web services, you configure for both the Genero Browser Client (GBC) and for the Genero Application Server (GAS).

You can create multiple GAS Configurations, each with a different name.
Note:

If you did not initially install the complete Genero Studio package, you must install and set up the Genero Application Server (GAS) outside of Genero Studio. See the Install and License your Genero Products manual.

When you select a GAS configuration, Genero Studio dynamically generates an application configuration file. This file enables you to run, debug, or preview an application or file.

During development, the GAS standalone dispatcher: httpdispatch can be used instead of a web server.

For the Genero Browser Client, specify the browser to use in General Preferences or in the Configuration Management dialog.

Configure for the Genero Browser Client

In the Display section of the Genero Configuration Management dialog, select the Use Application Server radio button. You can then edit the following fields:
Use Application Server
Select which GAS configuration to use. To add a new GAS configuration, click the Edit icon and enter details using the Genero Application Server Management dialog.
Application Type
Select Universal Agent to use the Genero Browser Client.
Select Web Application to use an earlier version of the Genero Web Client.

If you select Web Application, the Theme combobox box is activated and you can select from the available clients. You must be connected to a GAS that supports it; see the GAS documentation for the version you are using. To use the default client, leave the Theme combobox empty.

Browser
Specify the browser to use. If the Browser field is empty, the default browser is used.

If you select Browser, the Options field is activated and you can specify the options for starting the browser. For example, to start a Chrome browser in Incognito mode, enter "--incognito".

Important:

To set the --incognito option on MacOS, set the Browser field to "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome". If that option is not available, set it to "/Applications/Google Chrome.app".

Configure the Genero Application Server

In the Genero Application Server Management dialog, existing GAS configurations are listed in the left-hand panel. Select a configuration from the list to modify its settings. Use the integrated toolbar to add, duplicate, rename, or remove a configuration. Once a name is added, enter its settings.

In the GAS Connection Details section:
Host
Specify the IP address or the network name of the server you are connecting to when running an application with the GAS.
To connect to a GAS standalone dispatcher using a direct connection, specify the IP address or the network name of the Application Server (the one where the compiler resides). If the GAS standalone dispatcher is local, you can leave this field blank.
To connect through a web server, specify the IP address or the network name of the web server.
Port
Specify either the port of the GAS (for a direct connection to the GAS standalone dispatcher) or of the web server.
Important:

Changing the port number in the GAS Connection Details section does not automatically change the port number used when the GAS standalone dispatcher is launched!

If you are launching the GAS standalone dispatcher from Genero Studio, you must either modify the GAS configuration file to have the GAS listen at the same port, or you can add a startup script option to launch the standalone dispatcher at the proper port

If you modify the GAS configuration file, the change will impact all users of the GAS. By default, the GAS configuration file is named as.xcf, and the port number where the GAS listens for connections is the sum of the values of TCP_BASE_PORT and TCP_PORT_OFFSET. For more information about specifying the listening port for the GAS, see the Genero Application Server User Guide.

To launch the standalone GAS with a port number that differs from that in the GAS configuration file, add this option in the Start script options field, where XX is the port offset from 6300:

-E res.ic.port.offset=XX

For example, if you set the port value to "6399", you could start the httpdispatcher with the offset value of "99".

Connector
Leave blank if you are using a direct connection to a GAS standalone dispatcher. This is common in development environments.
For a Web server, enter the alias configured for your dispatcher in your GAS installation (often, gas). See the configuration topics in the Genero Application Server User Guide for more information on configuring your dispatcher.
Secure protocol
The URL used when launching an application is impacted by this selection.
When selected, the protocol is "https".
When not selected, the protocol is "http".
In the GAS Configuration Details section:
Installation directory
Directory where the GAS is installed locally.
Use start script
The check box specifies whether to use the startup script to launch the GAS. When checked, the field specifies which start script to be launched when this configuration is used. The GAS standalone dispatcher: httpdispatch can be specified here to launch httpdispatch. httpdispatch can be used as the GAS script. In versions prior to 2.50, set the environment by specifying -p <GASDIR> in the Start script options field. Alternatively, call a script that calls . ./envas before calling httpdispatch, such as:
. ./envas 
httpdispatch

For GAS versions prior to 2.30, set the path for gasd instead of for httpdispatch.

Note:

The start script is only used when no GAS is found on the host at the port specified. The start script is not called even if the GAS to be launched from start script is different from the one already launched.

Start script options
Specify any options to be used with the start script. See GAS standalone dispatcher: httpdispatch for httpdispatch options. For more information on script parameters, see the Genero Application Server User Guide.
In the Application Details section:
Application group
The name of the Application Group defined in the GAS as.xcf file. Enter the value _default for the group to use the default configuration file, unless you have an explicit group to specify.
Application directory
The directory of the Application Group, the same path as the one referred to in the as.xcf file. If using the default application, the corresponding directory (usually GAS installation directory/app) has to be entered in the Group Directory field.
Parent application
The identifier of the parent GWC application; if no identifier is given, the default GWC application will be used.
Services group
The name of the Web Services Group defined in the GAS as.xcf file. Enter the value _default for the group to use the default configuration file, unless you have an explicit group to specify.
Services directory
The directory of the Web Services Group, the same path as the one referred to in the as.xcf file. If using the default application, the corresponding directory (usually GAS installation directory/app) has to be entered in the Group Directory field.
Parent service
The identifier of the parent Web Services application; if no identifier is given, the default Web Service application will be used.
Tip:

If you change details in the GAS configuration fields, click Fetch to retrieve information from the GAS and validate the settings.

If you get an error message from the fetch, verify that the GAS is started, and that the host and port values are correct. The GAS should also be configured to allow Genero Studio access to the GAS monitor. By default, the GAS monitor can only be accessed from the localhost, and Genero Studio/gsserver must be on the same machine as the GAS to access it.

URL example

The URL used when launching application from Project Manager is impacted by the Secure protocol option and the Application Type selection:

<protocol>://<host>:<port>/<connector>/<application_type>/r/<application_name>
  • protocol is either "http" or "https", depending on the value of the Secure protocol option.
  • application_type is either "ua" or "wa", depending on the value of the Application type option.
  • application_name depends on the executed application in project manager.
  • Other values depend on the GAS configuration parameters.

Example GAS configuration

  • Host: <Automatic>
  • Port: 6394
  • Application group: mygroup
  • Group directory: c:\work
  • Parent application: defaultgwc
In this configuration, GAS applications will be run using the GAS located on the current computer at port "6394". The group "mygroup" in the as.xcf file points to the directory "c:\work"; the corresponding fields in the GWC configuration dialog are filled with the same information.
Note:

Users on Windows® 64-bit machines who are using a network proxy: The browser cannot open 127.0.0.1 or localhost unless you modify your Advanced Network settings to avoid going through the proxy for these addresses.
