I am getting the same response mention in the blog from servlet but not getting what need to pass in JSON PATH field of metadata schema to call servlet

[#2]

If I understand correctly you want servlet to provide the metadata instead of JSON file (as mentioned in blog)?

[#3]

Yes Navin. If you see the image available in blog has one property JSON PATH which is pointing to one .json file which is avaible in aem and providing yuu response . Instead of that i want to give servlet path which will provide the response

[#4]

I am not sure how to provide that path of servlet to get the response . Even you will see the blog comments, someone have asket the same quetion. I had tried to give the servlet path eg: /bin/dummyservlet.json  or /bin/dummyservlet.options.json or /bin/dummyservlet, but noting work for me. i am getting response servlet in below format

{"options":[{"value":"US","text":"United States"},{"value":"UK","text":"United Kingdom"}]}

You need to give servlet path and it should return the JSON data.

Also please make sure your content-type header should be set as application/json data type while returning the output.
