Pre-Configure a Launcher
- Install a Vision Client Launcher somewhere on network. Take note of the Installation directory you use, as a later step will involve finding this directory.
- Configure each application. Be mindful of the Gateway Address setting: the deployed launcher will need to be able find the Gateway based on the address you enter.
At this point, we should have a single launcher configured with one or more applications. Next we can zip up the the launcher and its configuration files.
Create a ZIP
In these steps, we will create a single ZIP, containing all of the required files.
- Navigate to the Launcher's installation directory. It should look similar to the image below:
Copy all of the files shown in Step 1, and paste them into the Client Launcher Data directory. This is the same directory that the configuration JSON file is located. The path differs by operating system, but should generally look like the following:
After pasting, the directory should look something like the following:
We now have a single folder containing the launcher, a JRE, and the application configurations.
Navigate up a directory to the ".ignition" folder. You will see the folder we were just in: "clientlauncher-data"
In this directory (the .ignition directory), create a new folder called .ignition. Note the leading period. In some operating systems you may have to attempt to rename with a trailing period as well.
- Copy the clientlauncher-data folder into the new .ignition folder. Note that you want to copy, not move. Moving would make prior application configurations on the local system unavailable.
Zip up the newer .ignition directory.
We now have a ZIP we can deploy to a new system.
Deploying the Launcher
- Take the ZIP, and move it to another computer.
Unzip the file at the user directory. The location of the directory is based on the local operating system.
The files should be unzipped. Navigate to the launcher at:
- Run the Launcher. It should contain all of the configured applications.
- At this point, consider creating a shortcut to the launcher, and placing the shortcut at a more accessible location. Alternatively, the launcher can be accessed via command line/terminal, so you could automate client launchers in a number of ways.
The client launcher can take advantage of a redundant Gateway setup. Whenever a connection is established with a master Gateway, the backup Gateway IP address is automatically stored in the client launcher configuration file. If the master Gateway cannot be contacted the next time the client launcher is run, an attempt is made to contact the backup Gateway. If the backup cannot be contacted, the client launcher switches between contacting the primary Gateway and the backup Gateway until one responds or the user closes the launcher.
Clients can be launched from the Client Launcher via command/terminal. When called in this way, many of the application properties may be overridden for the one call. The overrides use the same property names as noted in the Application Property Reference Table, under the "JSON name" column.
There are a few important notes when using the Command Line/Terminal to launch a project from the Vision Client Launcher.
- The Vision Client Launcher must be installed and have an application added for the Command Line/Terminal commands to work.
- The application argument requires the application name in the Launcher, not the project name. You can open the launcher to determine what the application name is. Adding new applications in the launcher uses the Project title by default.
Applications may contain spaces in their name. However, when launching from command/terminal, spaces should be escaped with %20. For example, if our application was named my project, then we could all it with the following:
Command Line Arguments
Launchers and SSL
When SSL is enabled on a Gateway, the Vision Client Launcher can take advantage of the enhanced security features associated with SSL.
Certificates Signed by a CA
When the Gateway's SSL certificates are signed by a recognized Certificate Authority, no additional configuration is required on the launcher.
When using a self-signed SSL certificate, the certificates for the Gateway must be locally accessible to the client launcher in the following directory:
When a certificate is placed in the directory above, the launcher will attempt to automatically add the certificate(s) to the local keystore upon application launch.
If the Vision Client Launcher fails to launch a client for some reason, the log file can be found at:
