Update the GBC runtime package on the GAS

Updates to the GBC often include changes to keep up with changing web technologies; as such, it is strongly recommended that you always use the latest version of the GBC.

If you are using the GBC runtime without any customization, you can deploy the most recent GBC runtime package to the Genero Application Server (GAS) from the command line or using the Deployment App.

Update runtime on GAS using the command line

Follow this procedure to deploy a GBC runtime package to the GAS from the command line.

Before you begin, you must have a GBC runtime package. To get the latest GBC runtime package, go to the Four Js Product Download Area and download the GBC runtime package: Genero Browser Client - Runtime package - Every OS.

Note:

To understand the syntax diagrams, see Syntax diagrams.

Set your environment by running the envas script ($FGLASDIR/envas or $FGLASDIR/envas.bat) for your GAS installation.
From a command prompt, deploy the GBC runtime package using the gasadmin command.
```
$ gasadmin gbc --deploy fjs-gbc-version[.suffix]-buildbuild-runtime.zip
```
The name of the runtime identifies the deployed GBC package.

Tip:
You can rename this file with a name that is shorter and easier to manage.

Specify this package as the default GBC client using the gasadmin command.

$ gasadmin gbc --default fjs-gbc-version[.suffix]-buildbuild-runtime.zip

View the list of deployed GBC clients.
```
$ gasadmin gbc --list
```
When the GBC is deployed, you can render your application using the default GBC with the following URL:
```
http://my.server.com:6394/ua/r/appName
```
Tip:
You can continue to use any (previously) deployed Genero Browser Clients by adding the URL parameter gbc=deployed_gbc_name to the end of the URL, for example:
```
http://my.server.com:6394/ua/r/appName?gbc=gbc-1.00.44
```

Update runtime on GAS using the Deployment app

The Deployment app provides a graphical interface for deploying GBC packages. It is provided as part of the Genero Identity Provider (GIP).

For instructions on setting up the GIP and using the Deployment app, please refer to the Single Sign-On User Guide.
