What are the options for embedding the Java compiler in web pages?

Question

Java

Good day to everyone, for the purposes of educational practice, an idea arose to create a Spring Framework project with a theme dedicated to online problem solving in Java using the compiler built right into the page. And the question is what to take as a basis for an online compiler, maybe there are web plugins that send data to the server, or remote services, or a module directly connected to the project? On JavaRush, for example, a certain Intellij Idea plugin is used to check solutions, but somehow I could not find anything about it on the Internet. Help with examples or explanation to understand this issue, thank you in advance.
