When to use value tag and value attribute?

By
A bean can be configured using either value attribute/tag, constructor injection. We should use value tag only when we need to configure a property instance variable in a class, else we should avoid it. Below is an example




<bean id="mappings" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<property name="properties">

<value>

jdbc.driver.className=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/mydb

value>

property>

bean>

AEM as a Cloud Service (AEMaaCS) – Architecture Overview

AEM as a Cloud Service (AEMaaCS) – Architecture Adobe Experience Manager (AEM) is one of the leading CMS from Adobe and is part of Adobe Experience Cloud (AEC). The Adobe Experience Manager (AEM) web content management offers a set of capabilities for creating, managing, delivering, and personalizing content across various digital marketing channels, including web, mobile, and email.  Before we dive into architecture of AEM as a Cloud Service (AEMaaCS) we need to understand why AEMaaCS is needed and how it is different as compared to classic AEM. To understand this, we’ll first look at: Evolution/history of AEM Challenges with traditional/classic AEM (the AEM that majority of us have used from last 10-12 years) Evolution/History of AEM The software was originally launched in early 2000 as Communiqué (CQ) by Day Software of Basel, Switzerland. After CQ 5.3 had been released, Day Software was acquired by Adobe Systems in 2010 then CQ became Adobe Experience Manager. From

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: org.apache.sling.api.resource.LoginException: Bundle org.eclipse.gemini.blueprint.extender is NOT whitelisted ): Image: neba Model Registry Menu Image: Error Screen 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 deprecat

AEM - Query list of components and templates

By
Some time while migration or for auditing purposes we need to know where a particular component/template or any other resource have been used. Have you ever wondered about how to fetch a list of all the paths where a particular component or template is being used? I this short article I am going to show a quick way to write a utility with which you can get list if paths (actual resource nodes) where a targeted resource is being used. Here is the code snipped: public void getResourceListHelper(Resource parentResource , String targetSearchPropertyKey ,  String targetSearchPropertyValue , List components ) {      Resource childResource ; for (Iterator resourceChildrenIter = parentResource .listChildren(); resourceChildrenIter .hasNext();  getResourceListHelper ( childResource, targetSearchPropertyKey, targetSearchPropertyValue, components)) { childResource = (Resource) resourceChildrenIter .next(); ValueMap childProperties = (ValueMap) childResource .adap

Custom synchronisation or rollout action for blueprint ?

By
Image
Blueprint is an important feature for all those sites which needs to deals with multiple locale and region specific sites. Consider that we have 20 different regional sites and each regional site have 2 locales (English and regional language). Now let’s say you need to do a small update on a English locale page and that changes is required on all sites, there will be 20 pages that you’ll need to visit and make changes one by one (if you have not used blueprint and live copy). With blueprint  we can create a master copy (which is called as blueprint) and create many live copies (which are actual sites) and the benefit you get is that as soon as you do any change in blueprint that same change will be propagated to all live copies pages when changes are rolled out by authors…this is cool. With blueprint you’ll need to apply changes only to English locale page on blueprint and all English locale pages (live copies) will receive that change implicitly. So, how this whole thing works? W
