Generation of nodes based on the values entered in the dialog of a component ??

YOu are on the right track. However -- if you want to call Java from a JSP (which is really what an AEM component is), instead of using a Servlet -- setup an OSGI bundle and call the OSGi bundle via sling.getService().

For example:
//This is a component so it can provide or consume services

@Component
  
@Service
public class NodeServiceImpl implements NodeService {
  

//method that uses the jcr api
public int  createNode()

{

       ... 
      //USE JCR API HERE TO CREATE NODES AND PERFORM OTHER JCR operations;

        return 0;

} 

}

From your JSP -- you can use sling to get an instance of NodeService and invoke createNode:

To see an article that puts this all together and uses the JCR API from within an OSGi bundle -- see:

Hope this helps

Hi Smacdonald,

Thanks for your reply.

I implemented the functionality with the help of Post Processor. Below are he steps to reproduce my method:

/**
 * Processes a POST request and sends appropriate response by creating child nodes
 */
@Service
@Component(metatype = true,immediate = true)
public class ParentPostProcessor implements SlingPostProcessor {
  //variables come here

    /**
     * processes the post request
     * @param request the request Object
     * @param changes the list of Modified properties.
     */
    public void process(SlingHttpServletRequest request, List<Modification> changes) {

    // This PostProcessor should only act on resources with "resourceType path"
        //and if the operation is not delete
        if (request.getResource().getResourceType().equals("mysite/components/myparent") 
            && !"delete".equals(request.getParameter(":operation")) {
            
            createChildNodes(request);
        }
    }

}
