Hello @shivanandh 

 

In Adobe Experience Manager (AEM), when you have multiple servlets registered with the same resource type, the selection of which servlet will serve the request depends on the OSGi service ranking 

OSGi service ranking is a property that can be set when registering a service in AEM. The servlet with the highest service ranking value will be selected to serve the request. 

For example, let's say you have two servlets registered with the same resource type:

Servlet A:
- Resource Type: "myapp/components/mycomponent"
- Service Ranking: 100

 

Servlet B:
- Resource Type: "myapp/components/mycomponent"
- Service Ranking: 200

 

In this case, Servlet B will be selected to serve the request because it has a higher service ranking value.
