Hi Team, we have a requirement to get session of an AEM instance in another(different) AEM instance. I know that using jackrabbit-standalone(JcrUtil.getRepository we can get in standalone application). Same logic is not working when we try to access on aem server

AEM version is : 6.5

java version : java 8

Please suggest if there is any way to achieve this

Hi,

I don’t think there is a way to connect remotely to another AEM instance via JCR. The traditional approach to address what you are trying to do is to have a "service" running on your AEM Target instance that performs the actions your AEM Source instance needs. This "service" could then be invoked from the AEM Source instance. I hope this makes sense.

For reference, check this link: Connecting an Instance of AEM to Another Remote Instance of AEM.

Hope this help

Hi EstebanBustamante,

Thank you for the reply!

Can we access JCR repo from spring boot application ?

I have tried adding the dependancy in local mvn repo & using it in pom.xml directly for testing purpose. However, logic works fine when I run the Java main Class from Eclipse

& not on spring boot application running on port 8080 with same logic

AEM is running on port 4502

Adding pom.xml is below for reference:
