I am currently working on a student management system project. I have connected my VS code to MOngoDB successfully. I also added the MongoDB connector jar file to my reference library (VS code). My code works on Eclipse but everytime I tried it to run on VS code it shows error. But VScode doesn’t show any error in my code. It only happens when I run it. Since the code is very long I am giving an exaple code:

import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoClient;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import org.bson.Document;
import static com.mongodb.client.model.Filters.eq;

public class MongoDBTest {
    public static void main(String[] args) {
  
        try (MongoClient mongoClient = MongoClients.create("mongodb://localhost:27017")) {
            
            MongoDatabase database = mongoClient.getDatabase("testdb");
            
            
            MongoCollection<Document> collection = database.getCollection("testCollection");
            
            // Create a document to insert
            Document doc = new Document("name", "Alice")
                            .append("age", 30)
                            .append("city", "New York");
            
            
            collection.insertOne(doc);
            System.out.println("Document inserted successfully");

            
            Document myDoc = collection.find(eq("name", "Alice")).first();
            if (myDoc != null) {
                System.out.println("Retrieved document: " + myDoc.toJson());
            } else {
                System.out.println("No document found with the name Alice");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Everytime I run the code it shows the following error:

I previously asked why I was getting errors while importing MongoDB libraries. I was getting errors beacuse I didn’t added the MongoDB connector jar to my project. But now I also added that but still showing the following error in the terminal.
