Accessing CQ component

Yes -- you can access an AEM Sling Servlet from a standard HTTP call. Your CQ Servlet can return data that you can display in another client. For example - your Servlet can obtain data from the AEM JCR and return it within a data set (ie - JSON).

Hi,

I understood the approach you have mentioned about accessing Sling servlet with HTTP call, but I am little bit confused about how to create data set having CQ component. e.g. in below code I have retrieved CQ Page instance from JCR.

ResourceResolver resourceResolver = resolverFactory.getAdministrativeResourceResolver(null);
Resource res = resourceResolver.getResource(location);
Page page = res.adaptTo(Page.class);

But I am not getting how I can return it within data set or JSON. If I do something like following code, then how 3rd party eCommerce system will convert CQ page object?

JSONObject jsonObj = new JSONObject();
jsonObj.put("page", page);

Please guide me how I can create data set/JSON which will contain CQ component?

Thanks,

Manju

Can anyone please give me some hint on how I can send CQ component to 3rd party eCommerce system? Do I have to convert component into any other object and then send it through JSON? How can I create data set/JSON for CQ component?

Please reply.

Hello Manju,

You can create a sling servlet as well that will read data and return Modified JSON view of page (http://sling.apache.org/documentation/the-sling-engine/servlets.html)

If you want a component to to accessible like JSON then create json.jsp under your component, write logic to render json output for that component, create a node of type cq:Page under say /etc/something with default redering as JSON based on above resource type. And then from your e commerce system call /etc/something path.

I think servlet would be easy :D

Example to access text component in json use [1]

[1]   http://localhost:4502/content/geometrixx/en/jcr:content/par/text_1.json

Hi Yogesh,

As I am beginner to CQ I dont know sending JSON will be good approach or not. What I want to implement is to fetch CQ component from JCR and display it on 3rd party eCommerce system. About 2nd approach you have mentioned above, I dont think we can directly access CQ data by just mentioning URL /etc/something in eCommerce system. What about authentication?

I will prefer to use Sling servlet but I still didnt understand how to read component data. Lets take example mentioned below

ResourceResolver resourceResolver = resolverFactory.getAdministrativeResourceResolver(null);
Resource res = resourceResolver.getResource("/content/testSite/customPage");
Page page = res.adaptTo(Page.class);

I have retrieved Page component from JCR. Now how should I read its data?

Is there any standard approach for such type of integration (displaying CQ component on 3rd party system front end)?

Thanks,

Manju
