Outdated Java Technologies: Why You Can Skip JSP, Struts, Hibernate, and Other Legacy Tools

JSP

JSP was once used as the View layer in MVC web applications, but most companies have moved to fully front‑end‑separated architectures where the back‑end only provides REST services. Consequently, learning JSP is no longer necessary.

Struts

Struts was a solid MVC framework, yet Spring MVC has become the dominant, all‑in‑one solution in the Java ecosystem. New projects now prefer Spring MVC, so beginners should start with it instead of Struts.

Hibernate

Hibernate offers powerful ORM capabilities but comes with high learning cost, complex configuration, and difficult performance tuning. Modern projects favor lightweight frameworks like MyBatis that combine ORM benefits with direct SQL access, making Hibernate less essential to learn.

Servlet (must master)

Although pure Servlet‑based applications are rare, Servlets remain the foundation of all Java web containers and MVC frameworks such as Spring MVC. Understanding the Servlet lifecycle enables deep customizations like request/response interception and security checks, so mastering Servlets is still crucial.

Other Technologies

In the Chinese market, Java is primarily used for web back‑end development, making several older technologies less relevant:

Applet : Browser plugins are obsolete.

Swing : Desktop UI is typically built with C++ (MFC) or C# (WinForms/WPF).

JDBC : While still useful, many frameworks (e.g., MyBatis) abstract it, so its priority can be lowered for beginners.

XML : Still used, but JSON is now the preferred data format for web services; deep XML API knowledge is unnecessary unless required.

Overall, focus on modern Java back‑end tools—Spring MVC, MyBatis, and a solid grasp of Servlets—while deprioritizing legacy technologies.
