J2EE is Sun's Java platform designed for large enterprise host-level computing types. It is a Java-centric environment for online development, construction and deployment of Web-based enterprise applications. Let me introduce you to J2EE. I hope it will be helpful to you.
What is J2EE
J2EE is the abbreviation of Java 2 Enterprise Edition, which is a set of specifications. Pattern; used to define distributed, multi-tier application development, deployment, and management of the Java programming language.
J2EE is a set of technical architecture that is completely different from traditional application development. It contains many components and can mainly simplify and standardize the development and deployment of application systems, thereby improving portability, security and reuse value.
J2EE provides solutions to the problems encountered by companies migrating to a multi-tier computing model. Issues addressed include reliability, scalability, security, application deployment, transaction processing, web interface design, and timely software development. It is built on Java 2 Platform, Standard Edition (J2SE) for multi-tier computing.
Advantages of J2EE
J2EE provides a good mechanism for building a business system with scalability, flexibility, and easy maintenance:
1. Efficient development
Due to the use of component technology, application development can be divided according to the skills of developers and developed in parallel, providing overall development efficiency. J2EE allows companies to offload some common and tedious server-side tasks to intermediate providers. In this way, developers can focus on how to create business logic, thus shortening development time accordingly.
2. Support heterogeneous environments and have strong portability
J2EE can develop portable programs deployed in heterogeneous environments. J2EE-based applications do not rely on any specific operating system, middleware, or hardware. Therefore, a properly designed J2EE-based program only needs to be developed once and can be deployed to various platforms.
3. Scalability
Applications based on the J2EE platform can be deployed on various operating systems; suppliers in the J2EE field provide a wider range of Load balancing strategy. It can eliminate bottlenecks in the system and allow integrated deployment of multiple servers. This deployment can reach thousands of processors, enabling a highly scalable system to meet the needs of future commercial applications.
4. Good reusability
Since each software component is strictly separated in the EJB model, the server can be assembled from existing software components Client applications can be assembled from existing JavaBeans, enabling software to be reused.
5. Easy to maintain
Component-based design simplifies application maintenance. Because components can be updated and replaced independently, new functionality can be easily added by updating specific components in the application.

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),
