Specify the GBC client in the application configuration file

For a single application, you can specify the GBC client to use in that application's configuration file.

In the application configuration file (.xcf), use the <GBC> element to specify the name of a GBC client to use.

For example:

<?xml version="1.0" encoding="UTF-8" ?>
<APPLICATION Parent="defaultgwc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
            xsi:noNamespaceSchemaLocation="http://www.4js.com/ns/gas/4.01/cfextwa.xsd">
 <EXECUTION>
    <PATH>myapps/app1/</PATH>
    <MODULE>myModule.42m</MODULE>
 </EXECUTION>
  <UA_OUTPUT>
    <PUBLIC_IMAGEPATH>$(res.public.resources)</PUBLIC_IMAGEPATH>
    <GBC>my_gbc</GBC>
  </UA_OUTPUT>
</APPLICATION>

In this example, my-gbc references the name of a GBC client.

Finding the GBC client

To find the GBC client, the GAS looks at the paths defined by the GBC_LOOKUP_PATH environment variable. The value of GBC_LOOKUP_PATH is set by the GAS configuration file (as.xcf). By default, it will look in these directories, in this order:

If the GAS was started with a dispatcher override that sets res.path.gbc.user to a directory, this directory is searched first. Using a dispatcher override to set res.path.gbc.user is a convenience intended for testing and development. Its use is not recommended for production sites.
Next, the directory specified by the res.gbc.deployment resource in the GAS configuration file (as.xcf). This resource defines the GBC deployment directory for the GAS.
Finally, the GBC folder in the FGL program directory. The GAS configuration file identifies this folder as $(res.fgldir)/web_utilities/gbc.

Important:

While it is possible to add paths to GBC_LOOKUP_PATH, it is recommended that you do NOT modify the value for this environment variable. If you deploy the GBC clients using either the Deployment App or the gasadmin deployment mechanism, your GBC clients will be in the correct location.

Next steps

Once you have completed your configuration, you can verify that the correct GBC client is used. Enter the application URL in a browser; this example uses the local standalone dispatcher:

http://localhost:6394/ua/r/myapp.

To find out which GBC client is being used, click on the Application information icon to open the Product identification dialog. The version number is appended with the suffix as defined by the GBC customization.

If your application does not load, the issue may be with your customized GBC runtime package. See topics such as Fix configuration issues in the Genero Browser Client User Guide.
