Proxy Floating

8min
The ProxyFloatingService is intended to be used with the on-premise Floating Server (Old)﻿ and is part of the Floating Client﻿ module.
Initializing the Proxy Floating Client module
At the minimum there are three parameters you will need to initialize the SDK:
apiKey, your company API key
sharedKey, company-specific encryption key, used when signing requests
productCode, an alphanumeric code identifying a specific product
The productCode is tied to a specific product the license applies to and is defined while creating the product.
Optional Configuration parameters for initializing the Floating Client SDK:
addShutdownHook indicates if you want the SDK to automatically release any currently active licenses on the device before you shut down the runtime process. Default is true.
enablePeriodicRegister enables periodic calls to register method to prolong the license usage. It will be prolonged every time the license has passed half of its floating timeout time. Usage time is set through the LicenseSpring platform with the floatingTimeout parameter in the product configuration
proxyRegisterSubscriber subscriber on periodic register, default implementation is IgnoreRegisterEventSubscriber, but you can add your own implementation to handle the onSuccess and onError of the periodic register. This, of course, isn't a parameter you need to worry about if you chose not to enable periodic checks.
requestLogging request logging for debug purposes, default is no request logging.
appVersion manually set the version of the application that's using the SDK.
enableRetrying enables the retry option on failed API call to the server. The call can be repeated for up to 4 times. Default is false
identityProvider set a custom IdentityProvider which generates unique keys for a particular device. Default implementation is based on ONCE_PER_PROCESS. More details on our Java Hardware (Device) IDs﻿﻿
requestTimeout set the timeout of requests make to API (in seconds), default is 10 seconds
Java
// configuration with only required parameters
// NOTE building a LicenseSpringConfiguration without required parameters will throw a ConfigurationException
try {
  ProxyConfiguration configuration = ProxyConfiguration.builder()
    .host("localhost")
    .port(8080)
    .product("pc")
    .build();
} catch (ConfigurationException e) {
  log.error(e.getCause().getMessage());
}

// Configuration with more parameters
try {
  ProxyConfiguration configuration = ProxyConfiguration.builder()
    .host("localhost")
    .port(8080)
    .product("pc")
    .addShutdownHook(false)
    .enablePeriodicCheck(false)
    .enableRetrying(true)
    .requestTimeout(60L)
    .build();
} catch (ConfigurationException e) {
  log.error(e.getCause().getMessage());
}

ProxyFloatingService
After setting up the SDK configuration, there are a number of methods and objects available to the app developer.
To make the ProxyFloatingService, initialize it by passing the ProxyConfiguration object you set up earlier.
Java
ProxyFloatingService service = new ProxyFloatingService(configuration);
ProxyFloatingService service = new ProxyFloatingService(configuration);
﻿
Now you can use the methods that the ProxyFloatingService provides.
register()
Registers the user by making a ProxyRequest which contains the product code from the ProxyConfiguration and the device ID which is provided by the IdentityProvider. Each registration lasts for the time specified in the LicenseSpring platform (floating timeout). In order to prolong the usage of the product, this method needs to be called periodically (this is automatically called in the background if the property enablePeriodicRegister in the ProxyConfiguration was set to true). Returns the LicenseData object which contains information about the license.
Java
try {
  LicenseData licenseData = service.register();
  System.out.println("You have " + licenseData.getFloatingTimeout() + " more minutes.");
} catch (LicenseSpringException e) {
  log.error(e.getCause().getMessage());
}
try {
  LicenseData licenseData = service.register();
  System.out.println("You have " + licenseData.getFloatingTimeout() + " more minutes.");
} catch (LicenseSpringException e) {
  log.error(e.getCause().getMessage());
}
﻿
unregister()
Unregisters the user, which by definition, frees up one user slot on the server. Returns true if the action was successful.
Java
try {
  if (service.unregister()) {
    System.out.println("You have been successfully unregistered from product " + configuration.getProduct());
  }
} catch (LicenseSpringException e) {
  log.error(e.getCause().getMessage());
}
try {
  if (service.unregister()) {
    System.out.println("You have been successfully unregistered from product " + configuration.getProduct());
  }
} catch (LicenseSpringException e) {
  log.error(e.getCause().getMessage());
}
﻿
getLicense()
Fetches the license information from the server for the product specified in the ProxyConfiguration object.
Java
try {
  if (service.unregister()) {
    System.out.println("You have been successfully unregistered from product " + configuration.getProduct());
  }
} catch (LicenseSpringException e) {
  log.error(e.getCause().getMessage());
}
try {
  if (service.unregister()) {
    System.out.println("You have been successfully unregistered from product " + configuration.getProduct());
  }
} catch (LicenseSpringException e) {
  log.error(e.getCause().getMessage());
}
﻿
getSettings()
Retrievers the server settings. The returned Settings object contains registrationExpiryMinutes, and an array of server addresses.
Java
try {
  Settings settings = service.getSettings();
  System.out.println("There are " + settings.getServers().length + "in your proxy network.");
  System.out.println("The registration expiry time for product " + configuration.getProduct() + " is " +
                     settings.getRegistrationExpiryMinutes() + " minutes");
} catch (LicenseSpringException e) {
  log.error(e.getCause().getMessage());
}try {
  if (service.unregister()) {
    System.out.println("You have been successfully unregistered from product " + configuration.getProduct());
  }
} catch (LicenseSpringException e) {
  log.error(e.getCause().getMessage());
}
try {
  Settings settings = service.getSettings();
  System.out.println("There are " + settings.getServers().length + "in your proxy network.");
  System.out.println("The registration expiry time for product " + configuration.getProduct() + " is " +
                     settings.getRegistrationExpiryMinutes() + " minutes");
} catch (LicenseSpringException e) {
  log.error(e.getCause().getMessage());
}try {
  if (service.unregister()) {
    System.out.println("You have been successfully unregistered from product " + configuration.getProduct());
  }
} catch (LicenseSpringException e) {
  log.error(e.getCause().getMessage());
}
﻿
pingServer()
Pings the local proxy server.
Java
try {
  service.pingServer();
  System.out.println("The proxy server is up and running. :)");
} catch (LicenseSpringException e) {
  System.out.println("There is something wrong with your local server, this application cannot connect to it.");
  System.out.println("Please check why: " + e.getCause().getMessage());
}
try {
  service.pingServer();
  System.out.println("The proxy server is up and running. :)");
} catch (LicenseSpringException e) {
  System.out.println("There is something wrong with your local server, this application cannot connect to it.");
  System.out.println("Please check why: " + e.getCause().getMessage());
}
