AEM 6.3 - Bundle Whitelisting - Deprecation of administrative authentication

I stumbled on an issue when I was using neab with AEM 6.3. I created few neba ResourceModels and when I tried to access neba Model Registry, I got an error (java.lang.IllegalStateException: Bundle org.eclipse.gemini.blueprint.extender is NOT whitelisted):

NOTE: Neba team has already fixed it on their development branch and we don’t need to explicitly add whitelisting configuration for neba bundle.
Here is the reason for error Originally the ResourceResolverFactory.getAdministrativeResourceResolver and SlingRepository.loginAdministrative methods have been defined to provide access to the resource tree and JCR Repository. These methods proved to be inappropriate because they allow for much too broad access. Consequently these methods are being deprecated and will be removed in future releases of the service implementations. The following methods are deprecated: ResourceResolverFactory.getAdministr…

Part 1 - Angular 2 with AEM – Introduction, Challenges, Installation and Prerequisite

I am writing about AEM after long time and there is reason for that :-) I was learning something else interesting and that interesting thing is frontend technologies. So far in my professional career I have spent most of my time in designing and developing server side applications mainly using Java technology stack (Spring, ORM, JMS and what not) with basic UI development using JSP/JSF, HTML, Velocity, Sightly, jQuery, ExtJS etc. Also, in last few years I have delivered many applications which is combination of AEM, other CMS and Java backend but, I felt that still there is something missing and that missing piece is end to end knowledge of frontend development. So that’s what I was focusing on frontend development in recent past. I thought it is good time to combine frontend development knowledge with AEM and come up with something interesting that might help my friends out there.
In this multi series post (and tutorial in coming parts of this series), I’ll show you how you can use An…

Part 2 - AEM with Angular 2 – Building project using Gulp and Maven

Angular 2 is modular in nature, what that means is there are number of smaller modules that you can choose to mix and match based on what is required in your project. When you are developing Angular 2 application outside of AEM this is not a big challenge in terms of building and shipping an Angular 2 application out of the door because there are many build tools (e.g. Angular 2 CLI) are available to take care of bundling and packaging these angular modules and dependencies. But, when we are in AEM, components are just building blocks and content authors can drag-drop these components anywhere and as many times as they need so, reusability is key i.e. authors should be able to use Angular 2 components in same way as regular AEM component. So this mean build tools that are available today for Angular 2 application can’t help because those tools need to know upfront where components have been used and then these tools compiles applications but, in AEM this is different because authors c…
