Update templates Jakarta EE:

1. Open NetBeans Templates Manager

In NetBeans, go to: Tools → Templates
In the Templates dialog, expand: Project → Web -> Servlet
Update javax to jakarta:

import jakarta.servlet.ServletException;
import jakarta.servlet.annotation.WebServlet;
import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;
import java.io.IOException;

Maven Web Application

Step 1: Create a New Maven Web Application

Open NetBeans 13.
Go to File → New Project.
Choose:
- Categories: Java with Maven
- Projects: Web Application
Click Next.
Fill in:
- Project Name: JSP_Shop
- Project Location: Choose your preferred workspace folder.
- Group ID: com.jsp.shop
- Artifact ID: jsp-shop
- Version: 1.0-SNAPSHOT
Click Next.

Step 2: Configure Server & Java Version

In Server, select Apache Tomcat 10.0.23.
In Java EE Version, choose Jakarta EE 9 Web (Tomcat 10+ uses Jakarta namespaces).
Make sure Java Platform is JDK 1.8_231.

Step 3: Verify Folder Structure

Your Maven project will have:

jsp-shop/
 ├─ src/main/java/      (Java source files)
 ├─ src/main/resources/ (Config files)
 ├─ src/main/webapp/    (JSP, HTML, CSS, JS)
 │    ├─ META-INF/
 │    ├─ WEB-INF/
 │    │    └─ web.xml
 └─ pom.xml             (Maven configuration)

Step 4: Edit pom.xml

Add dependencies for JSP and Servlet:

<dependencies>
    <!-- Servlet API -->
    <dependency>
        <groupId>jakarta.servlet</groupId>
        <artifactId>jakarta.servlet-api</artifactId>
        <version>5.0.0</version>
        <scope>provided</scope>
    </dependency>

    <!-- JSP API -->
    <dependency>
        <groupId>org.glassfish.web</groupId>
        <artifactId>jakarta.servlet.jsp.jstl</artifactId>
        <version>2.0.0</version>
    </dependency>
</dependencies>

Note: Scope provided means the server (Tomcat) will provide these libraries at runtime.

Step 5: Create Your First JSP File

Right-click src/main/webapp → New → JSP File.
Name it index.jsp.
Add simple HTML:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Welcome to JSP Shop</title>
</head>
<body>
    <h1>Hello, JSP World!</h1>
</body>
</html>

Step 6: Configure web.xml (Optional)

If you want to set a default welcome page:

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

Step 7: Build & Run

Right-click project → Clean and Build.
Right-click project → Run.

The browser should open:

http://localhost:8080/jsp-shop

You’ll see Hello, JSP World!
