java.util.concurrent.ExecutionException: Failed to initialize component

Question

I'm working for a maven web application and I'm struggling with this error and I can't find any solution:

It comes from running a index.jsp page that imports multiple other classes:

<%@page import="java.util.ArrayList" %>
<%@page import="java.util.List" %>
<%@page import= "java.net.URL" %>

<%@ page language="java" contentType="text/html; charset=US-ASCII" pageEncoding="US-ASCII"%>

From what I found so far, it says that some JAR files could be corrupt so I just deleted them from my lib file. After that I got an error like Java error: Only a type can be imported. XYZ resolves to a package that I also couldn't solve and just sent me back to add all jars in the lib folder in WEB-INF. I tried deleting my repository then maven install again, didn't work. I checked the versions of my jars and everything, I tried lots of things but nothing seem to work so far. Here is my pom.xml for reference:

 <properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
 <java.version>1.8</java.version>

Here is my project structure in Eclipse:

Do you have any idea how I can deal with this issue? I really don't see where problem is.

this was quite a common suggestion that I got while trying to solve previous issues. If I take them out I got the other error I mentioned and the solution was to add jars. It's like a loop that I don't know how to get out of — Paul Buciuman, May 31 '19 at 17:40

If you look into the following exception stacktrace which says,

Caused by: java.lang.IllegalArgumentException: java.util.zip.ZipException: error in opening zip file

It means, the war file is not proper from a deployment view point. Besides, you have to create war packaging in maven. Apart from that, you have to use maven war plugin. You have to make a complete web project in eclipse also. I will suggest to go through the following tutorials to get an idea.

I just created a new project using the tutorial you provided. I want to make sure all my classes and dependencies are placed in the right way so I have these questions now: do I put my packages inside the java resources/src folder? Also, should I add the jars inside the lib folder in WEB-INF? Should I user a classes folder as well under WEB-INF? – Paul Buciuman May 31 '19 at 18:09
If you are using IDE like eclipse, you can create packages by right click and select to create a package. – Sambit May 31 '19 at 18:10
I never worked with war files so I have a dummy question: do I still work with jar files in the same way? adding dependencies in pom.xml? – Paul Buciuman May 31 '19 at 18:28

You have to deploy the war file for web application. Check this link. https://stackoverflow.com/questions/5871053/difference-between-jar-and-war-in-java – Sambit May 31 '19 at 18:30
is there a way this error can be solved without using war files? – Paul Buciuman Jun 01 '19 at 00:47
