Hi All,

 

There are certain use-cases where we would like to access the values stored in particular components in servlet. This might or might not be the use case for @kattakiran1990 

 

@kattakiran1990 to achieve this, use the below code

 

Resource resource = resourceResolver.getResource("/content/we-retail/language-masters/en/user/jcr:content/root/responsivegrid/user");
UserModel model = resource.adaptTo(UserModel.class);

 

Hope this helps!

 

Thanks,

Kiran Vedantam.

    @kattakiran1990 ,

       Could you please help me understand what is the usecase you are trying to achieve ? I am not understanding the requirement to send the values from a Sling Model to Servlet ?

      I would do something like this:

      HTL:

       <div data-sly-list.pathlist="${resource.getChildren}">
		<div data-sly-test="${pathlist.name == 'multiField'}">   
			<div data-sly-list.multiplePathList= "${pathlist.getChildren}">
				<input type="hidden" id="multiplePathList" value="${multiplePathList.propName}"></input>
			</div>		
		</div>
	</div>

      JS:

       

       

      let multiFieldValue = document.QuerySelector("#multiplePathList").value;
      var url = "servletPath?" + "multiplePathList=" + multiplePathList;

      Java:

      String[] multiplePathList = StringUtils.isNotBlank(request.getParameter("multiplePathList")) ? request.getParameter("multiplePathList").split(",") : null;

        Hi,

        you need to get all param in javascript and then you can sepaarte them and send to servlet, I would suggest use post request to send all as a single param with multivalues

         

        const pathItems = userList.querySelectorAll("#multiplePathlist");
        let values = "";

pathItems.forEach(function(userItem) { 
          values = values + item.value + ","; 
        });

          @kattakiran1990 What is the reason you want to pass values from sling model to servlet ? 

           

          If you really want to use servlet, as @manikanthar1295 suggested,  you can try below using request / resource resolver. 

           

          SlingModel model = request.adaptTo(SlingModel.class);

          Or 

          SlingModel model = resourceResolver.adaptTo(SlingModel.class);

              Still it's not clear to me the reason why you want to use servlet,  but you can simply try with osgi service and achieve similar: 

               

              1. Create Interface: 

              public interface ISampleService {
                   testMethod(Strig args);
              }

              2. Create service: 

              @Component(service = ISampleService.class,immediate=true)

              public class SampleService {
                         testMethod(Strig args){

                                //write logic

                        } 
              }

               

              3. Call OSGI service from sling model:

               

              public class SlingModel{

              @OSGiService
              private ISammpleService sampleService;

                 

              @PostConstruct
              protected void init() {

                   sampleService.testMethod(pass required arguments here);

              }

              } 

              Hope this helps you.

                Hi @kattakiran1990 

                 

                In Sling servlet you can use below code and try

                 

                Model model =resourceResolver.adaptTo(model.class)

                 

                then u use   the getter method as you need.

                 

                Regards
