5. How Can Inherit Properties Of One Dialog To Another Dialog?


For Inheriting the Properties Have To Create Two Components With the Unique Names In Base Component Dialog. For Eg. If Plan Is To Have Two Rich Text Two Rich Text Areas In Dialog Of Components That Inherit From Base, Then Must Include the Two Rich Text Areas With Unique Names In Base Component Dialog. In Any Case Every Input Field Of Dialog Must Have Unique Name, Else They Will Point To a Same Property Path Relative To Jcr:content Node Of The Component When Used On the Page.

6. What Is Dependency/Dependencies In Client Library?


  Term Description Examples

External software components or libraries that the client library relies on for specific tasks.

External libraries, modules, or frameworks.
Dependency Management Tools or systems used to handle the installation, versioning, and resolution of dependencies. Package Managers (npm, pip, Maven, etc.)

17. Difference Between OSGi Bundle And Normal Jar File?


OSGi Bundles Are the Jar Files With Metadata Inside. Much Of This Metadata Is In Jar’s Manifest, Found At META-INF/MANIFEST.MF. This Metadata, When Read By OSGi Runtime Container, Is What Gives Bundle Its Power. With OSGi, Just Because A Class Is a Public Doesn’t Mean Can Get To It. All Bundles Include the Export List Of Package Names, And If Package Isn’t In The Export List, It Doesn’t Exist To Outside World. This Allows Developers To Build Extensive Internal Class Hierarchy And Minimize Surface Area Of Bundle’s API Without Abusing Notion Of a Package-Private Visibility.

18. What Is Meant By JCR (Java Content Repository)?


A Java Content Repository Uses JSR-170 API To Access The Content Repository Using the Java, Independent Of Physical Implementation.

    • Select Enabled Checkbox To Make Folder And Its Assets Available Only To the Closed User Group.

    38. What is technology stack that CQ5 is based on?


    The CQ5 technology stack is based on the three technologies. These technologies are Apache Sling, OSGI (Apache Felix), and Java Content Repository (JCR). Apache Sling is the RESTful framework that is used to access the jcr over http protocol. It will map that request url to the node in jcr. OSGI is a framework that is used for a modular application development using the Java. Each module, which is called the bundle, can be stopped and started independently during a runtime.

    39. What is sightly?


    Sightly is HTML templating language that was introduced in an AEM 6.0. It is meant to take place of JSP files and is the preferred templating system for HTML. The name sightly means “pleasing to eye”, and its focus is to keep markup beautiful and maintainable.

    40. What is listener’s property in AEM?


    The listener’s property in AEM for the component is used to define what happens before or after an action on component. This is added by using “cq: listeners” node with the node type of “cq: EditListenersConfig”. The listener’s property can also be added to the any widget in AEM. To add the listener to that widget just need to add to add node that is called “listeners” with the type of “nt: unstructured”. Then just need to add child nodes to “listeners” node that are events of that widget.

    41. How do load digital assets in dam?


    Can add digital assets to the dam by using graphical user interface or through the WebDav access. If using the graphical user interface, would just browse for the selected files would like to add, and then cq will create a metadata for those assets in dam folder. And would generally use WebDav option when want to upload the large number of assets at once.

    42. How do build bundle through crxde?


    Can build a bundle through the crxde by navigating to source folder of project located under “apps”. Once do this, right-click on “src” folder and choose to create bundle. This will open wizard that will walk through creating a bundle. It is recommended that no longer use crxde to create the OSGI bundles for AEM. Instead, should be using Maven.

    43. What is purpose of Activator.java file?


    The purpose of the Activator.java file is that is to be notified any time there are bundle start and stop events for bundle. The Activator.java file is the optional listener class that is created when create a bundle through the crxde.

    44. What is CQ5 overlay/override component?


    The overlay/override component is used when need to use an out of box component in AEM and want to add extra features to it and want to change it across all instances of that component.

    45. What is difference between dialog and design dialog?


    A dialog is the key element of component because they provide interface for authors to configure and provide input to component. This input will be stored at the page level in jcr. A design dialog is the dialog that will only display when are in design mode in AEM. The input that is received here will be stored at template level and will be accessed across whole site.

    46. What is extending a component?


    Extending a component is when want to create new component that will not override the base component but will have same features as the original so that can change or build upon that component. To extend component, must set “sling:resourceSuperType” of component to base component would like to extend. By doing this, will inherit everything from a base component.

    47. How does sightly differ from other templating systems?


    Sightly differs from the other templating systems in three ways. Sightly is a secure by default, it offers the separation of concerns, and sightly is HTML5 because it is valid HTML5 file. Sightly is secure by a default because it automatically filters and escapes all the variables being output to the presentation layer to prevent a cross-site-scripting vulnerabilities. Sightly offers the separation of concern because it is purposely limited to be ensure that a real programming language is used to express corresponding logic. This is done through Use-API pattern.

    48. Can create a page without template?


    Pages are usually created by selecting the template for page when create them in Website console. However, a page can be created manually in crxde by using same properties that are created when make a page in a Website console.

    49. What are xtypes and how are useful in AEM?


    In the ExtJS language, xtype is the symbolic name given to class. In AEM these xtypes are widgets that are used in creation of components. AEM comes with the bunch of widgets that are available out of box. can also create and define own xtype to be used in AEM. An example of xytpe is when creating a dialog for component, and want author to be able to enter text, would add a “cq: Widget” that has xtype property of “text field”.

    50. How do add properties to Page Properties dialog?


    Access Page/Document Properties: In your CMS, website builder, or document editing software, find the option to edit properties.

    Open Properties Dialog: Look for “Page Properties,” “Page Settings,” or “Document Properties.”

When this resource is located, sling resource type is extracted, and then it is used to locate script to be used for rendering that content.

    55. What design patterns used in AEM?


    Since AEM is built using the OSGI, many of the design patterns for OSGI are valid. Some of these design patterns are the Singleton (Service), Adapter Service, Resource Adapter Service, and Whiteboard. Also, since AEM is a modular, should be able to use any design pattern in the application.
