Servlet (Server Applet) is the abbreviation of Java Servlet, which is called a small service program or service connector. It is a server-side program written in Java. Its main function is to interactively browse and modify data and generate dynamic Web content.
This Servlet implements the following functions: when a user accesses the Servlet through a browser, the Servlet returns an HTML page to the client browser. Enter the following content in Edit-Plus and compile it to get ShowHtml.class.
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Hello World</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1 id="Hello-nbsp-World">Hello World!</h1>");
out.println("</body>");
out.println("</html>");
}
}Add in the web.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems,Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet>
<servlet-name>HtmlServlet</servlet-name>
<servlet-class>com.JavaBean.ShowHtml</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HtmlServlet</servlet-name>
<url-pattern>/htmlservlet</url-pattern>
</servlet-mapping>
</web-app>The above is the operation tutorial on how Servlet generates html pages. Hope it helps everyone.

Mastering Java: Understanding Its Core Features and CapabilitiesMay 07, 2025 pm 06:49 PMThe core features of Java include platform independence, object-oriented design and a rich standard library. 1) Object-oriented design makes the code more flexible and maintainable through polymorphic features. 2) The garbage collection mechanism liberates the memory management burden of developers, but it needs to be optimized to avoid performance problems. 3) The standard library provides powerful tools from collections to networks, but data structures should be selected carefully to keep the code concise.

How does platform independence benefit enterprise-level Java applications?May 03, 2025 am 12:23 AMJava is widely used in enterprise-level applications because of its platform independence. 1) Platform independence is implemented through Java virtual machine (JVM), so that the code can run on any platform that supports Java. 2) It simplifies cross-platform deployment and development processes, providing greater flexibility and scalability. 3) However, it is necessary to pay attention to performance differences and third-party library compatibility and adopt best practices such as using pure Java code and cross-platform testing.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
