I am new to front end developing. I have so far a back-end program written in java with Eclipse that does all I want, saves the output in an object and prints it in the console (for my convenience).
My goal is to display this output information dynamically (meaning that the backend part of the program might update and send new output) in a webpage on a local server. Hence I have "transformed" or "added" a Dynamical webpage to my Eclipse project using "Project Facets" in Eclipse Project Properties, and created an index.jsp file hosted on a tomcat server (See picture of the File organisation).
Ultimately, I want to have my index.jsp file open in my browser and when my backend program (which I assume I have to compile in an executable jar) detects changes , display those changes in the webpage. Also, I have a button on my webpage for which I would like to send information back to my backend program when it is clicked.
Should I use POST request in my backend with the URL of the index.jsp (although I don t want to display the information in a form, just regular text and images)?
or create a Javabean class in the webcontent/WEB-INF/ (if I can access and modify it dynamically from my backend) and then use that to get and set data from the jsp page?
or am I obliged to use something like Spring ?
I ve heard I should seperate backend and front end, but I don t really understand how they communicate dynamically !
Thank you for your help !
