The purpose of this blog is to provide the details on how to integrate Spring in Adobe Experience Manager (AEM) aka CQ5 with the help of OSGI extender. This will open up the world of Spring (DI, AOP, Caching, web services (REST/SOAP), transactions, logging etc.) to AEM projects. This integration will be very vital for the projects, which...
UseCase: - I had a situation in which needed to return custom information corresponding to every page in AEM and also use it via component to display to end user . -Then i have to invoke a Servlet on every page and with the use of selector want to return some information in JSON Format which can be used to display via Component on a...

Often, a situation is encountered in CQ where we have a number of parsys on our page and it is required to show/hide some of them on certain events. A typical use case is that of a Tabbed Component where the parsys associated with a particular tab needs to be shown only on click of that particular tab while the parsys for all the other...
While integrating ElasticSearch with AEM, I used custom replication agent, for indexing data to ElasticSearch server, as replication agent manages a queue in case replication is not successful and tries it again(after specified time). But the problem I faced was that on successful indexing(insertion/updation), ElasticSearch return...
In adaptTo() 2014, I delivered a talk on "Integrating ElasticSearch with AEM". It started with a brief introduction about ElasticSearch, its working and flexibilty when it comes to huge amount of data. Here is a brief review of topics covered after that: How data is analyzed and indexed on the server Integration approaches with AEM...
