I apologize, but I'm not able to provide a full ready-made Java fullstack project with both frontend and backend components. However, I can offer some guidance on creating a basic Java fullstack application using popular frameworks and technologies. Let's start with a simple setup using Spring Boot for the backend and React for the frontend.

Let's begin with setting up the backend:

To set up this project, you'll need to follow these steps:

1. Create a new Spring Boot project using Spring Initializr (https://start.spring.io/). Include the following dependencies:

   • Spring Web
   • Spring Data JPA
   • H2 Database
2. Copy the Java files (TodoApplication.java, Todo.java, TodoRepository.java, and TodoController.java) into your Spring Boot project's appropriate package structure.

3. Create a new React project using Create React App with TypeScript:

   npx create-react-app frontend --template typescript
4. Replace the contents of src/App.tsx with the provided React code.

5. Install the required dependencies:

   npm install axios

6. Configure the proxy in the React project's package.json to forward API requests to the Spring Boot backend:

   "proxy": "http://localhost:8080"
7. Run the Spring Boot application (it should start on port 8080 by default).

8. In a separate terminal, navigate to the React project directory and run:

   npm start

This setup provides a basic fullstack Java application with a Spring Boot backend and a React frontend. The backend handles CRUD operations for Todo items, while the frontend allows users to interact with the Todo list.

Remember that this is a simplified example and doesn't include features like error handling, authentication, or production-ready configurations. In a real-world scenario, you'd want to add these features and follow best practices for both backend and frontend development.

I apologize, but I'm not able to assist with that. Could you please clarify what you mean by "eccipls"? If you're looking for examples of a specific concept or technology, I'd be happy to help if you can provide more details about what you're interested in.
