In reply to Giuliano Peretti. Hello Giuliano, Ajax POST call is jus a sample, that if you have to make a POST ajax call, you can use mentioned syntax. doGet example i am showing using browser hit directly. I am sorry , if i failed to explain. I will take out some time this weekend and restructure it for your better clarity.

This article is a mess…
You declare a Servlet with GET method and call it with POST, using resourceType implies that you have to use “jcr:content” to invoke it

Hi Ankur,

I am little bit confused.

You created servlet with resource type and same resource type you mentioned in page level jcr:content property. Now you are accessing servlet by using below URL.

http://localhost:4502/content/geometrixx/en/jcr:content.data.html.

The above URL is looks like page URL.

Now I have a component there in that I am making ajax call using above URL and I added this component in same page. Now my question is can I use same component in different page(Ajax call will work). I will not add any resource type in that page.

Could you please help me.

Thanks,
Satish

Hi, Will implementing the resource type servlet I am getting additional this HTML code in the response. If I call a servlet through the ajax then it will give an error due to this. So how can I stop this additional code. Is there any other way in which we can provide the path of the node instead of /app/demo/component/page, the node is present in the /content/ and we can add selector also.

@Satish – is POST call to sling servlet with resource type resolved? I am also facing the same issue. Already check:
1. Passing method is “POST”
2. extended SlingAllMethodsServlet

@Ankur – Can you please help here?

AEM version is 6.2

In reply to satish. 2 things for post check that you are passing methods = "POST" and instead of SlingSafeMethodsServlet you are extending SlingAllMethodsServlet

Hi,
I am trying to implement the post servlet in similar manner.
– created a servlet with resourceType = “/bin/customPath”
– created a page with ‘sling:resourceType = /bin/customPath”
– when I tried to hit the page URL as post method with proper payload, request is not hitting my servlet.
– the same thing worked for GET though.
Am I missing any config changes here?

Any suggestion would be helpful.
Thank you!

In reply to kumar. You cannot call OSGi service from front-end (AJAX). OSGI services can be injected into a component as well as servlets. OSGi services and servlets serve a completely different purpose. Infact it's always a good practice to use OSGi service inside a servlet. Any interactions with JCR, or complex business logic are best segregated to an OSGI service. Servlets should be created if you need the JCR content to be exposed to external REST based clients.

In reply to Shivani. Shivani, you are correct. It should be page/jcr:content as it has the resourceType property.
