- The difference between nodejs and tomcat
- The main differences between Node.js and Tomcat are: Runtime: Node.js is based on JavaScript runtime, while Tomcat is a Java Servlet container. I/O model: Node.js uses an asynchronous non-blocking model, while Tomcat is synchronous blocking. Concurrency handling: Node.js handles concurrency through an event loop, while Tomcat uses a thread pool. Application scenarios: Node.js is suitable for real-time, data-intensive and high-concurrency applications, and Tomcat is suitable for traditional Java web applications.

- How are Java Servlets deployed and run?
- JavaServlet is deployed and run through a Servlet container. Deployment involves writing a Servlet class, packaging it as a WAR file, and copying it to the container's deployment directory. The container loads the WAR file, creates a Servlet instance, and calls Servlet methods to generate a response when the client requests it. For example, to use Tomcat to deploy a Servlet, first define the Servlet and its URL mapping, and then package it together with the Servlet class into my-servlet.war. Copy the WAR file to Tomcat's webapps directory and start the server. Access the specified URL to run the Servlet, which will generate a message containing "HelloW

- Why localhost8080 cannot be accessed?
- 7 common reasons and solutions for localhost:8080 being inaccessible: Make sure the firewall has opened port 8080. Confirm that an application is listening on port 8080. Check if any other application is using port 8080. Disable or change the IPv6 address to resolve the conflict. Check DNS records to resolve domain name issues. Clear your browser cache to resolve caching issues. Troubleshoot other causes such as network connectivity, configuration, or malware.

- What is the difference between Java Servlet and CGI?
- The difference between JavaServlet and CGI is that Servlet is hosted by a server container, while CGI is an independent executable program. Servlet requires a JavaEE server, and CGI can run on a web server that supports CGI. Servlet performance is usually better than CGI and has higher security.

- What are the advantages and disadvantages of how Java Servlets work?
- JavaServlet is a Java class used to build dynamic web pages and serves as a bridge between client and server. Working principle: receive requests, initialize Servlet, process requests, generate responses and close Servlet. Pros: Portable, scalable, secure and easy to use. Disadvantages: Overhead, coupling, and state management. Practical case: Create a simple Servlet to display the "Hello, Servlet!" message.

- How are Java Servlets used in distributed applications?
- In distributed applications, JavaServlet can achieve seamless communication across multiple servers. Its principles include: Client request: The client issues an HTTP request to the server. Servlet container: The container receives the request and instantiates the corresponding Servlet. Servlet call: Servlet performs request processing, generates and sends response. Load balancing: Multiple servers distribute requests through load balancing strategies to avoid overload.
