VS Code Setup Help for Maven Web App and Apache Tomcat Server

Guys, I am learning Servlet, JSP, and Hibernate, and I want to build a project using them—a Maven Web Project. My plan is to first set up a Maven Web Project and then use JSP, Servlet, and Hibernate to build the project in VS Code.

Additionally, I want to see real-time changes—whenever I modify my index.jsp file or anything else, it should reflect immediately after starting the server. I have tried everything and watched 20+ videos, but I am still unable to properly set up or configure my Maven Web App with the Tomcat server....

Performance testing of call with insertion of million records

Is there a way to do some testing where you test endpoints that pull million record from an api and do a bulk insert into a db. How would I add a performance test on this? Aside from calling the endpoint directly to test. I want to simulate or mock the data objects as well.

What is wrong with my code?

Hello! I am trying to code along but am not getting the same result. I have been inspecting my code so much I feel a bit blind, so could I perhaps get a second pair of eyes, with maybe a bit more knowledge? I am learning Spring, working with Spring Boot & Databases. It is not much code, three classes so if it's not minded I will just share it here....

Own video streaming

Hi, for my project I would like to implement on-demand video streaming. Currently I have no clue, should I implement it myself or should I use a third party api which is expensive. If it's not hard to implement it myself, it's not worth paying for third party. What do you recommend, maybe you have your own experience and can make a guide for it?
