How to Enable Configuration for OSGI Components with R6
Adding configuration to OSGi Component(s) is as simple as annotating your class with @Designate(ocd=””) annotation with the “ocd” property, and to make the @Activate method accepts an config param; as indicated below: 1234567891011121314// /com/sourcedcode/services/impl/MyserviceImpl.java import org.osgi.service.component.annotations.Activate; import org.osgi.service.component.annotations.Component; import org.osgi.service.metatype.annotations.Designate; @Component(service = MyService.class, immediate = true) @Designate(ocd = SourcedCodeSiteSettingsConfig.class) public class MyserviceImpl extends MyService { […]
OSGI R6 Configuration @AttributeDefinition Essentials Reference Guide
When defining any OSGI component’s configuration its standard practice to use Declarative Services; these configurations can be edited in the OSGI Apache Felix Console. This can be done by creating a class interface with the annotated @ObjectClassDefinition, which includes a determined list of rules as @AttributeDefinition items. The @AttributeDefinition defines the supporting configuration for a […]

AEM Sling Model Constructor Injection
Sling Models field injection, @inject, are used to support injection of AEM Library-specific context objects. However, there is an alternative way to inject AEM objects into Sling Models, and its called Constructor Injection. The benefits of Sling Model Constructor Injection: Does not store the injection references to the adaptable. Since it does not store injection […]
AEM Sling Model Field Injection vs Constructor Injection Memory Consumption
Article was last updated on June 7th, 2020. Sling Models field injectors are used to support injection of AEM Library-specific context objects. For example, @ScriptVariable SightlyWCMMode will inject the WCMMode object, @ScriptVariable Resource will inject the current resource object, and @ScriptVariable Style will inject the Style object. These objects are typically stored within the object, […]
AEM Sling Model Injectors Annotations Reference Guide
The Apache Sling Model enables injector specific annotations which aggregate the standard annotations for each of the available injector, which are: Script Bindings, Value Map, Resource Path, Child Resources, Request Attributes, OSGI Services, Self, and the Sling Object. Sure we can invoke injectors by the @inject, followed by the @source annotation (with an injector name) […]
JUnit 4: AEM Sling Servlet Unit Test Example Using wcm.io AEM Mocks, Servlet by Resource Type
This article will demonstrate how to write AEM Unit tests for @SlingServletResourceTypes (OSGi DS 1.4 (R7) component property type annotations) using the Junit4 testing framework. With developers being more visual, the source code is posted below. Technologies here used are: AEM project archetype 19 (link) Mockito 2.27.0 (link) AEM Mocks JUnit 4 2.7.2 (link) This […]
Registering @SlingServletPaths Component Property Type
You are probably looking for the @SlingServletPaths, OSGi DS 1.4 (R7) component property type annotations for Sling Servlets, code/unit test examples and was not successful. Apache recommends not use the @SlingServletPaths annotation, Sling Servlet register by a path. Rather to use the @SlingServletResourceTypes component type. Given the drawbacks in the caveats below, it is strongly […]
Sugar Coat Registered AEM Servlet Scripts and Paths Endpoint
In AEM we tend to write Sling Servlet OSGI Services to expose JSON data using the various service reference properties such as “sling.servlet.paths”, “sling.servlet.resourceTypes”, “sling.servlet.selectors”, and “sling.servlet.extensions”. Example 1: DirectoriesServlet.Java doGet Servlet Implementation (html extension): This is an example how a servlet in AEM to retrieve the directories JSON data. 1234567891011121314151617// example for /content/mysite.directories.html @SlingServlet( […]
What is a Servlet in AEM?
What is a Servlet? A Servlet is a class used to extend capabilities of servers that host applications accessed by means of a request-response programming model; we know most the HTTP protocol. In AEM, Servlets are typically registered as an OSGI service. The reference of the “sling.servlet.paths” or “sling.servlet.resourceTypes” must be set, or the Servlet […]
Improve Performance of AEM Components During Development Phase
Web performance is how quick web pages are successfully downloaded and viewable on the visitor’s browser. When we say “Web Performance Optimization”, this means that we are optimising or increasing web performance. Quicker download speeds of websites, in general, have shown in user contentment, retention, and loyalty. Especially with AEM enterprise websites, our motive is […]
Scenario: Building AEM Components with 3rd Party Integrations in a High Performance and Scalable Way
we are assigned to build a hospital search component in a very high traffic website. This hospital search component allows users to search for available hospital private rooms across the United States; there are approximately 200,000 hospital private rooms across the US. The hospital search component, presented in the view, simply has an input field […]
How to Check all Active Run Modes in a Running AEM Instance.
The fastest way to retrieve all active run modes that are enabled within a running AEM instance would be from the OSGI console, Apache Sling Settings. Follow the two simple steps below: Log in to AEM as an admin or a user who has access to the OSGI console using this URL: http://localhost:4502/crx/de/index.jsp Navigate to […]
How to write Javascript Unit Tests for AEM Client Libraries with Jest
This article demonstrates how to set up and run Javascript Jest unit test for client libraries. As a part of this setup, code coverage will be produced by Jest. With this implementation, we will utilise the frontend-maven-plugin, where it makes it possible to run npm scripts apart of the maven build. Most of the time, […]
JUnit 4: AEM WCMUsePojo Unit Test Example (Passing Paramaters)
