It's hard to know if your question is on-topic because it's very confusing.

Node is a server-side JavaScript runtime. It can be used to run JavaScript code 
on the server. Often, people use that capability to create a web server. That 
web server can produce HTML and send it to a client (i.e. web browser) which 
interprets and displays it the same way it would were it received from any 
other web server stack (e.g. Apache or Nginx, possibly having been generated by 
PHP, etc.). Your web server that you create in JavaScript and run with Node can 
of course send other types of files to the client (web browser) as well, such 
as images, stylesheets or JavaScript scripts, which the browser will interpret 
the same way it always does.

The JavaScript language is perfectly powerful, and the Node runtime is a great 
place to run JavaScript on the server, especially when combined with 
pre-written npm modules. JavaScript in a web browser is more limited by 
necessity of the security concerns inherent in running untrusted code. You 
wouldn't want any random web site you visit to be able to have direct access to 
the files on your disk, for example, so a web browser doesn't allow JavaScript 
to do that, but JavaScript in Node doesn't have those limitations.

So, what, specifically, is the data you are sending from your remote Java app 
to your Node JavaScript app? Can you give an example? And then, in what format 
does it have to appear on the web page? Can you show any code of what you've 
done so far, and show us what it currently outputs or does and what you want it 
to output or do instead?
