Java - Web - API : Build a small application that sends XML request and receives XML response

Job ID: 32271472

Budget: $10 – $30 USD

I want to demonstrate a Java based application where users can upload multiple documents and submit the transaction in XML to an API and check its status through another API by sending another XML.

I have a document class that contains a file class. This document class is a member of a Txn class that I want to save. Document objects with uploaded files should display in the list.

I need to generate and send XML to APIs (URL given) and get its XML response and parse its values. I have an XSD to validate the XML.

I was trying to build this in Grails but facing some issues. I need this in Java 8 or 11.

I will share the sample files in grails.
