Deploying a WAR File in Tomcat 7: A Beginner's Guide
When deploying a WAR (web application archive) file in Tomcat 7, an automatic deployment process generally occurs. Here's how to deploy your WAR file:
- Copy the WAR File: Place the sample.war file in the webapps directory of your Tomcat installation.
- Access Your Application: The deployed application can be accessed at http://localhost:8080/sample. This is possible because Tomcat automatically extracts the WAR file into a folder with the same name within the webapps directory.
- Monitor the Deployment: After copying the WAR file, check the webapps folder for the extracted folder sample. If it's not created, or if the application doesn't open properly, inspect the log files (e.g., tomcat/logs/catalina.out) to identify any deployment issues.
Additional Notes:
- The auto-deployment process can be adjusted using the context.xml configuration file located in the META-INF directory of the WAR file.
- If you encounter errors during deployment, ensure that the WEB-INF/web.xml file complies with the Servlet specifications and that all required dependencies are present.
- To redeploy an existing WAR file, simply overwrite the old file in the webapps directory. Tomcat will automatically detect the change and restart the application.

The Java compiler realizes Java's platform independence by converting source code into platform-independent bytecode, allowing Java programs to run on any operating system with JVM installed.

Java cannot achieve 100% platform independence, but its platform independence is implemented through JVM and bytecode to ensure that the code runs on different platforms. Specific implementations include: 1. Compilation into bytecode; 2. Interpretation and execution of JVM; 3. Consistency of the standard library. However, JVM implementation differences, operating system and hardware differences, and compatibility of third-party libraries may affect its platform independence.

Java realizes platform independence through "write once, run everywhere" and improves code maintainability: 1. High code reuse and reduces duplicate development; 2. Low maintenance cost, only one modification is required; 3. High team collaboration efficiency is high, convenient for knowledge sharing.

The main challenges facing creating a JVM on a new platform include hardware compatibility, operating system compatibility, and performance optimization. 1. Hardware compatibility: It is necessary to ensure that the JVM can correctly use the processor instruction set of the new platform, such as RISC-V. 2. Operating system compatibility: The JVM needs to correctly call the system API of the new platform, such as Linux. 3. Performance optimization: Performance testing and tuning are required, and the garbage collection strategy is adjusted to adapt to the memory characteristics of the new platform.

JVM works by converting Java code into machine code and managing resources. 1) Class loading: Load the .class file into memory. 2) Runtime data area: manage memory area. 3) Execution engine: interpret or compile execution bytecode. 4) Local method interface: interact with the operating system through JNI.

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),
