This application demonstrates my blog post about Feature Toggles and their different usage as Permissioning Toggles.

First clone this repository and open it with your favorite IDE/editor.

Then;

1. I assume Sentinel runtime & device driver are already installed.

2. Sentinel JNI and runtime libraries should be set otherwise the application will throw this error and stopped;

   Exception in thread "main" java.lang.reflect.InvocationTargetException
   	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
   	at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

   Caused by: java.lang.UnsatisfiedLinkError: no HASPJava in java.library.path
   

   You can find these files in Sentinel Samples. You will need hasp_darwin_demo.dylib and libHASPJava.dylib files under MacOSX. Files for Linux and/or Windows are provided in the samples too. Read more.

   And the runtime can be downloaded from Sentinel web site.

3. You should change the VENDOR_CODE to login the Sentinel HL dongle otherwise the application will not started;

   12:13:29.704 [main] DEBUG com.azizunsal.blog.permissioningtoggles.helper.HaspHelper - HASP login result for 0 is false
   12:13:29.710 [main] INFO com.azizunsal.blog.permissioningtoggles.helper.HaspHelper - The HASP error description for code '22' is 'Invalid vendor code!'
   12:13:29.711 [main] ERROR com.azizunsal.blog.permissioningtoggles.PermissioningTogglesSampleApplication - Sentinel HL check is NOT ok!
   

1. Then you will need to make changes in HaspHelper (in checkLicense method) to be able to properly run the application.

$ ./gradlew assemble && java -jar build/libs/permissioningtoggles-0.0.1-SNAPSHOT.jar

Or if you want to use Docker container;

$ docker build -t azizunsal/permissioningtoggles .
$ docker run --privileged -d -p 8082:8082 azizunsal/permissioningtoggles

Let's run the application with the default and camera profiles

INFO 32983 --- [           main] .p.PermissioningTogglesSampleApplication : The following profiles are active: camera

and then make a request to the camera controller;

azizunsal:~/ $ curl --request GET https://localhost:8082/cameras
[]%

We received an empty result.

Now make a request to the Video Controller

azizunsal:~/ $ curl --request GET https://localhost:8082/videos 
{"timestamp":"2019-10-31T13:14:14.763+0000","status":404,"error":"Not Found","message":"No message available","path":"/videos"}%

As you see, if video permission couldn't be found then the related class won't be bootstrapped.
