What approach should I take to understand a large J2EE application if I don't know any of the frameworks involved yet?

Hope this helps I am assuming that the "superb programmers" are still around, so your best bet is to use them. While not every developer is great at explaining things, they should be able to give you an overview of the application so that you can understand what each framework provides and how they work together.
The first thing to accomplish is WHAT, not HOW. Get guidance and hopefully design documentation that will allow you to understand what each piece of the puzzle provides to the solution as a whole.

What's the best approach in auditing a big java/j2ee web application

wish helps you I had two web applications with similar settings as you. I stopped using FindBugs and Checkstyle as they showed more than 10.000 problematic points. The applications used JDBC level data access, JSP for presentation and a custom framework for request dispatching. Luckily for me, these low level settings allowed me to do the extensions and fixes on medium difficulty. During the 3 year project, only about 20% of the original code remained as it were. Sooner or later everything else needed to be either changed, replaced or removed (and finally I was able to use FindBugs and Checkstyle).
We too faced the dilemma of complete rewrite. However, there were several factors against it:

This might help you So, your ActionLink will generate a hyperlink, which means it's a GET request to the server.
MVC has some smart defaults that send that link click to the Delete action in your controller.
code :
[HttpPost, ActionName("Delete")]

I wish this helpful for you interate is a stream source and limit is an intermediate operation. We have to remember 2 important things about intermediate operations: they return a new Stream and they are always lazy. So limit will return a new Stream consisting of the elements of the original stream IntStream.iterate(0, i -> i + 2), truncated to be no longer than maxSize 3 in length. Laziness simply means that nothing is going to happen unless you add a terminal operation such as forEach,count,anyMathch or any other. So with all this in mind, we can think about our code
code :
IntStream.iterate(0, i -> i + 2).limit(3).forEach(System.out::println);
new LimitedStream(new InfinitiveStream(0, i -> i + 2),3).forEach(print);
for (int i = 0, limit = 0; ; i += 2, limit++) {
        System.out.println(i);
        if (limit == 2) {
            break;
        }
}

like below fixes the issue Case sensitivity critically hits you. - it's Name not name. Besides that, you forgot [0] since you have an array of arrays.
Try $strain_data[0]['Name']

fixed the issue. Will look into that further Basically the line super(int health, int strength, int speed, int type); keeps giving me an error that says... , Remove type of parameters and add parameters to class constructor.
