To develop a webpage in Java language with all actions, you will need to:

Create a Java project.
Create a HTML file.
Create a Java servlet.
Configure the servlet.
Deploy the servlet.

Here are the steps in more detail:

Create a Java project.

To create a Java project, you can use an IDE like Eclipse or IntelliJ IDEA. In Eclipse, you can create a new project by selecting File > New > Project and selecting Java Project from the list of project types. In IntelliJ IDEA, you can create a new project by selecting File > New > Project and selecting Java from the list of project types.

Create a HTML file.

To create a HTML file, you can use a text editor like Notepad or Sublime Text. In Notepad, you can create a new file by selecting File > New. In Sublime Text, you can create a new file by pressing Ctrl+N.

The HTML file should contain the following code:

Code snippet

<!DOCTYPE html>
<html>
<head>
<title>My Webpage</title>
</head>
<body>
<h1>My Webpage</h1>
<p>This is my webpage.</p>
</body>
</html>

Create a Java servlet.

To create a Java servlet, you can use an IDE like Eclipse or IntelliJ IDEA. In Eclipse, you can create a new servlet by selecting File > New > Class and selecting Servlet from the list of class types. In IntelliJ IDEA, you can create a new servlet by selecting File > New > Java Class and selecting Servlet from the list of class types.

The servlet should contain the following code:

package com.example;

import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;

public class MyServlet extends HttpServlet {

Code snippet

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.setContentType("text/html");
    response.getWriter().write("<html><head><title>My Webpage</title></head><body><h1>My Webpage</h1><p>This is my webpage.</p></body></html>");
}

}

Configure the servlet.

To configure the servlet, you will need to add the following entry to the web.xml file:

Code snippet

<servlet>
    <servlet-name>myServlet</servlet-name>
    <servlet-class>com.example.MyServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>myServlet</servlet-name>
    <url-pattern>/myServlet</url-pattern>
</servlet-mapping>

Deploy the servlet.

To deploy the servlet, you will need to copy the servlet JAR file to the WEB-INF/lib directory of your web application. You will also need to restart the web server.

Once you have completed these steps, you will be able to access your webpage by opening a web browser and navigating to the URL http://localhost:8080/myWebapp/myServlet.
