Servlet for fetching data from one node and using that data elsewhere

Say I have multiple pages under /content/practice/articles. Now in /content/practice/articles/firstpage/jcr:content there is a property named myImage. I want to read and fetch that value from myImage property which is a path basically.

 

Now I want to navigate to /content/practice/articles/firstpage/jcr:content/root/container/detailed_page and replace the properties (mainImage & smallImage) value with the data fetched from myImage property.

 

Can someone help me with the servlet code that I need to write in order to fetch the same?

 

Note : There are 500 pages under /content/practice/articles and I would have to do the above for all of them.

    Hi @nitin_laad , need some more help. Can you please surround this with try/catch block? And in my scenario there are 500 pages under /content/practice/articles. So can you please format the code accordingly?

    Like get all nodes under that path and then maybe fetch that nod get the property value and then replace the existing value with this recent one?
